Re: [PHP] Re: Need login suggestions

[Bobby Pejman]

I would also agree that allowing parent registration could be risky.  What you 
may be able to do just off the top is create a UserLevel field in your users 
table and assign value 1 for all those who say they're students.  That is, if 
you have no student ids at your disposal.

Then, when parents register, you can ask who their kid is, and assign a user 
level 2, for example.  When a parent finishes their registration, don't allow 
them access.  Display a message saying you'll have to call in to get your 
password or something similar.

What you're essentially doing is identifying parents by their user level yet 
making sure parents are parents.

Just an idea I thought I share.

 We're building a large site for a school district, to be used by both
 students and parents.  When a student logs in, they gain some access to the
 site, and when a parent logs in, they gain access to other sections on the
 site.  That's all fine and dandy, it's the actual registration process that
 I'm having a hard time with.
 
  
 
 How to determine if a registration is a student or a parent.  Do I simply
 give them a check box (or other method) to pick from (student or parent) and
 hope they're being honest?  Has anyone here have to deal with that in the
 past, and would you be willing to give me some ideas of what you did?
 Thanks!


Ideally you need to be able to unambiguously identify either a student
or a parent, you're best bet is to go for student - thus try and find a
single bit of information that both a student and you know about that
student, possibilities are:

  student id
  class
  teacher
  year

and so forth.. if the person signing up has any of these things then
they must be a student.

Best,

Nathan

[PHP] Overwrite value of true or false in PHP

[Bobby Pejman]

Hi,

I noticed that the following returns a 1.

echo (12) ? True : False

I was under the impression that true/false are of type boolean and not int.  
But in php anything other than 0 translates to true, meaning a 1.  What I am 
trying to achieve is for a 1 to be a 1 and a true or false to be a true and 
false respectively and I do not want to put quotes around the word true/false 
either because then it is no longer a boolean but string.

Is it possible to overwrite php's true/false and declare them as boolean?  You 
often see in C++, some use Define().

Thanks.

Re: [PHP] Overwrite value of true or false in PHP

[Bobby Pejman]

I see what's going on now.  Because of the type conversion, I am writing my 
code such that my return codes are translated to a strict 1 or 0.  The idea of 
having anything other than '' or 0 translating to a true scares me a little but 
thanks for pointing out the === operator.  I had to rewrite a lot of code after 
discovering it.  Good times...

Thanks for clarifying everyone.

Yes *true* and *false* are booleans.
PHP convert natively different types to boolean in order to help write
sentences like this

if( $object )
{
$object-something();
}

while( $data = mysql_fetch_assoc( $resource ) )
{
print_r( $data );
}

But we you try to print a boolean variable PHP convert it to string: true
becomes '1' and false becomes ''. That's why you can't just echo a boolean
variable to see the value, but you can rely on var_dump to show this.

$bool = true;
echo $bool;
var_dump( $bool );

$bool =! $bool;
echo $bool;
var_dump( $bool );


As other languages PHP as an special operator for checking types while
comparing values.

$a = 'false';
$b = true;

var_dump(
   $a == $b, # -- true
   $a === $b # -- false
);

This happens because values are converted before comparison so, 'false'
becomes true.
PHP converts everything different to an empty string as *true*
This also affect any type of variable.

Re: [PHP] how to check function's execution?

[Bobby Pejman]

Your dbupdate is probably executing a mysql_query command.  Is so, update 
results from mysql_query will be either true on success or false on failure.  
If your query also fails due to perms it will return false.

[PHP] ZEND Certification

I'm sure this has been asked in the past, but I figured up to date info
never hurts.  I'm going to be scheduling my certification soon, but I wanted
to hear from any of you that recently got zend certified recently and if you
had any advice.

Is there any particular portion I should make sure I have strong knowledge
of more than any other?

Any sites with good advice for this exam?

I have read countless online tutorials, but perhaps there are some good ones
out there I have passed upany good links?

I have read the official Zend Certification guide - which with all the
grammatical mistakes, I still was able to make sense of 98% of it or at
least knew that when they made a mistake, I knew it was a mistake and what
should have been there.

Anyway, any certification advice, any at all would be much
appreciated...

Subject: [PHP] Why does this work on one server, but not another?

Hi gang:

I posted this question to a MySQL list, but apparently it stumped them. So,
I'll ask here:

On one server, the following code works without any problems whatsoever:

--- quote ---

$sqlString = INSERT INTO $dbtable (id, image_type, image_large,
image_small, image_width, image_height, image_name, image_size, date_time,
date_created ) VALUES ('', '{$type}', '{$image_large}', '{$image_small}',
'{$width}', '{$height}','{$name}', '{$size}', '{$date_time}',
'{$date_created}'); $result = mysql_query($sqlString)  or die(2. 
Error in query $sqlString  . mysql_error());

--- un-quote ---

However, on another server, it doesn't (remember the code is identical for
both).

I have looked at the PHP Info on both servers, the php versions are
different (4.3.10 v 4.4.2) but the mysql specifics are identical except the
version differs slightly (v 4.1.15 v 4.1.14).

A clue, on the server it chokes on, if I reduce the image size to 100 x 67
pixels, it will work. 
However, if the image is 150 x 100 pixels, or greater, it will crater.

The error message is:

2. Error in query INSERT INTO as_table2 (id, image_type, image_large,
image_small, image_width, image_height, image_name, image_size, date_time,
date_created ) VALUES ('', 'image/jpeg', 'ÿØÿà\0JFIF\
-snip- (the entire text file for the image) 'v_small.jpg', '32',
'2006-03-22 14:10:55',
'2006-03-22 14:10:55') You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right syntax to
use near

[PHP] explode() an array and grep out a string

[Bobby R . Cox]

Hi all.

Is it possible to explode an array and have it exclude a certain 
string.   I currently have an array that is an ldapsearch that returns 
sub-accounts of a parent account. These accounts are then displayed so 
customer can either change the passwd or delete them.Thing is 
ldapsearch returns everymatch which includes the parent account, which 
is already listed on the page as the parent account.  I would like to 
eliminate the second listing of the parent account where the 
sub-accounts are listed.

This is where the array is collected:

$search = ldap_search($connection,dc=isp,dc=com, 
ispParentAcct=$sessUsername);

$entries = ldap_get_entries($connection, $search);
$num = $entries[count];
if ($num) {
$sessSubAccounts = ;
$i = 0;
while ($i  $num) {
$sessSubAccounts .= 
$entries[$i][uid][0] . |;
$i++;
}
}
One thing I would like to point out is that I did not have this problem 
before, but when I updated to a new version of openldap the following 
ldapsearch would no longer return the subaccounts:

$search = ldap_search($connection,dc=isp,dc=com, 
homeDirectory=/home/$sessUsername/*);

Any idea why that may be?

This is where the array is exploded:

?
   $i = 0;
 if ($sessSubAccounts) {

   $accounts = explode(|, $sessSubAccounts);

while ($i  count($accounts) - 1)
  ?

[PHP] ldap_add - Error number 65: Object class violation

[Bobby R . Cox]

Hi All.

Our ISP has a web page that allows ISP customers to add sub-email 
accounts to their existing accounts.  The information is stored on an 
LDAP server and added via the ldap_add command.

Currently I am getting the following error when trying to add a sub 
account.

Warning: LDAP: add operation could not be completed. in 
/usr/web/pmt.coop/htdocs/userTools/email/doAddCheckEmail.php on line 63
An error occurred. Error number 65: Object class violation

The following is a list of the object classes and attributes as they 
appear in the script.

// prepare data
$info[uid]= $addEmail;
$info[cn]= $sessCN;
$info[l]= $sessL;
$info[givenname] = $sessGivenname;
$info[mail] = $addEmail . @pmt.org;
$info[userpassword] = {CRYPT}.crypt($password);
$info[loginshell] = /bin/bash;
$info[homedirectory] = /home/ . $sessUsername . / 
. $addEm
ail;
$info[gidnumber] = 101;
$info[uidnumber] = 9514;
$info[uidnumber] = 9514;
$info[gecos] = $sessCN;
$info[mailMessageStore] =/home/vmail/pmt/$addEmail/;
$info[ispParentAcct] =$sessUsername;

$info[objectclass][0] = person;
$info[objectclass][1] = organizationalPerson;
$info[objectclass][2] = inetOrgPerson;
$info[objectclass][3] = posixAccount;
$info[objectclass][4] = top;
$info[objectclass][5] = shadowAccount;
$info[objectclass][6] = qmailUser;
$info[objectclass][7] = ispAccount;
The following is the line that is generating the error.

 // add data to directory
$r=ldap_add($connection, $dn, $info);
  if ($r) {
echo Added LDAP data ;
  }
  else {
  echo An error occurred. Error number  . 
ldap_errno($connection) . :
  . ldap_err2str(ldap_errno($connection));
 }

I am beating my head trying to figure this one out.  I know it's an 
object class violation, but I can't figure out if it's one that is in 
place or one that I am missing.  I thought that it may have been the 
ispAccount OC, but removing that and the ispParentAcct did not resolve 
the error.  I hope someone can help.   I apologize if this is better 
directed to the openldap list.

$HTTP_SESSION_VARS[$user][$options] = 'registered';

[PHP] Re: how to auto create a new page on the fly

[Bobby Patel]

also look into output buffering.
so you would then do these steps

1. start buffer
2. redirect all output to varaible $output
3. echo Static HTML code (from opening to closing html tags)
4. when completly done all output, the variable $output should have all the
html code
5. then using filesystem functions (fopen, etc...) dump variable into that
newly created file and then you are done.

If you have questions just post onto the list, but check the filesystem
methods and the output buffering methods (ob_start, ob_flush, etc...).

[PHP] Re: Mail funtion question

[Bobby Patel]

I haven't worked with PHP mail for a while, but since no one has responded
I'll give you something to consider:

1. Why don't you try error suppression , @ ? or you can set error_reporting
down or you can capture all output by using output buffering.
2. You can trap the invalid email, but it may be *more* complex and result
in a slower script. You will have to evaluate this for yourself,

$emails = array (); #array of email info
# In the form
# $emails[0] = array (email = mailto:'[EMAIL PROTECTED]' , name = 'Reciever
Name');
# $emails[1] = array (email = mailto:'[EMAIL PROTECTED]' , name = 'Reciever Name
2');

$invalid_emails = array();
foreach ($emails as $index = $info){

$result = @mail ($info['email'], 'Bulk Newsletter Subject', 'email
messafge') ;
if (!$result) {
$invalid_emails [] = $info['email']; // capture invalid email
}
}

Please note, that the code above will call mail once for each email, so if
you have 100 emails this will run 100 times, where as if you stacked all the
emails into one mail call. But then you may not be able to find the invalid
emails.

[PHP] Re: Hiding URL's...

[Bobby Patel]

If you want to restrict the download to once per user, the best is to use a
database (or a I guess a file) which keeps tracks of who can download it and
downloaded status, etc..

I haven't worked directly with this issue, but I would start by having a
table Permissions with columns username, articleID, downloaded, authKey (and
whatever else you may want). Then present the link to the user as
getFile.php?auth=$authKey.
where getFile.php is
?php
$query = select downloaded, articleID from Permissions Where authKey =
$_POST['auth'];
$result = mysql_query ($query);
if ($result) {
$row = mysql_fetch_array ($result, MYSQL_ASSOC);
if ($row ['downloaded'] == 'N') {
# Update table and set downloaded = 'Y'
# Select the text of article from Articles table or from disk and
store in variable $contents
header (content/type pdf); # or text/plain, or whatever type you
need
echo $contents;
exit();
}
}
?

OK, I got tired of coding near the end (since I know you can do that), but I
think that this may be better. If you just pass the file name to the script
then you have to do checks that the user has access but how? Unless the user
already logged in to a members area I guess.

Anyways, there are problems to this script, for example if the download was
terminated half way through, it's already set that it has been downloaded
(maybe you can do the update query after the echo $contents, but I don't
think that will help).

That's my $0.02

 I built a basic php script where they add the sisters and their names,
grad.
 date, and email.  Is there anyway to build a page that shows all the
fields
 where someone could go in and edit/add what they need?  What I basically
 want is a webpage that works like MyCC SQL Database.  The only thing I've
 been able to figure out is a basic update page, but using that they have
to
 type in everything again- so for example if they want to change the email
 address, they'd have to retype the names and grad. date.  So I'd like a
 script that shows all the rows and columns and allows someone to go in and
 change whatever field they want.

 Any help greatly appreciated,
 Hedges

[PHP] Re: PHP webpage like MySQL, PART 2

[Bobby Patel]

Are you talking about editing mutiple rows at the same time?
if so there is no efficient way to check what row has been edited and which
haven't. What I would is use HTML variable arrays for the names of the
fields.
example you have input type='text' name='FirstName' size='20'
maxlength='20' value='Allison'  change the name attribute to name =
[data][$id][FirstName], so now you have all variables grouped (note the use
if a fixed index 'data', explination in foreach loop ). Then your script
will loop through the POST variables and do sequential UPDATES
example
foreach ($_POST[data] as $ID = $Field) {
$query  =  Update tablename Set First = '$Field[FirstName'], Last =
'$Field[LastName'],  Where id = $ID; #List all fields in the set clause
mysql_query($query);

}

The reason for the initial 'data' index is so you can safely loop through a
cetrain part of the post array. If you left that out you would deal with
extra variables like submit, and other hidden fields.

It's a little hard to work with multi-dimensional arrays, so what I usually
do to help me is use the var_dump() on the passed POST array.
So take a look at var_dimp(), HTML with array indexes, the foreach loop
construct.

HOWEVER, if you need to just let the user edit 1 row, what you have is fine
all you have to do is pass the id number thourgh a HTML hidden field. So
when you pull the rest of the fields and spitting out HTML spit this out
somewhere in between the form tags :: input type='hidden' name='id'
value='$id'

 Many hanks for ya'lls help earlier.

 I've figured out how to pull the data and edit it:
 http://www.hedges.org/aoii/olemiss/updatesister.php

 However, for some reason I can't get it to edit whatever row.  In the code
 (pasted below) I have to specificy $id=row to edit...

 I can't figure out how to make it to where the user can select the field
 (which is the id/row) and edit it.  I've tried putting a ?id=# at the end
of
 the url, but that doesn't work...  Any thoughts?  So what I want is where
it
 says

 $id=1

 to have it someway where that is a variable that the user can define...





 Thank you.

[PHP] Re: PHP should know my data!

[Bobby Patel]

auto-populate data, as in putting in mock data depending on column type? or
transferring data from another data source.
If the former, you can look at 3rd party sources (I think I saw one from
winSQL), if the latter you can convert any data source to a (tab, comma,
etc.) delimeted  file which you can load into MySQL through your own PHP
script or I'm sure there is some php script out there that loads in CVS
files.

[PHP] Re: Input Submi Help

[Bobby Patel]

I thought you could, but actually I dont think you can ... however there is
this little hack I just came up with.
FORM Example
form  action = 'redirect.php

input type = 'submit' name = 'Page1' value = goto Page 1
input type = 'submit' name = 'Page2' value = goto Page 2

/form

Code for redirect.php
?php

# Has button 1 been pushed/sent?
if (isset ($HTTP_POST_VARS['Page1'])) {
include ('page1.php');
exit(); #optional depending on programming style
}
# Has button 2 been pushed/sent?
elseif (isset ($HTTP_POST_VARS['Page2'])) {
include ('page2.php');
exit(); #optional depending on programming style
}
# Both buttons NOT been pushed/sent
else {
die ('no page selected');
}
?

I hope you are familiar enough with PHP to understand the above. Basically
depending on what Page variable was passed from the submit button, then you
pull that script (either page1.php or page2.php).  Note: The name attribute
of the submit button must match in the POST array and also are case
sensitive.

 I have a script that contains a form which goes to page1.php on the

 things to fill out that get passed to page1.php.  I want to put another
 button in there that send all the same names and values of the
 checkboxes to page2.php.  Is this possible to have 2 buttons going to 2
 different places, but using the same data for all other form elements?
 I would really appreciate any help I can get.  Thanks.

[PHP] Re: Value for entire file

[Bobby Patel]

it should be in the $_GET or $HTTP_GET_VARS array in the index.php script.
put this at the top of your index.php script

var_dump ($_GET); # or $HTTP_GET_VARS depending on PHP version

and see if the value is there. Also, if you are using the value in a
function and you have PHP  4.1.0 (I think), GET array is not global so to
get this value you have to declare the array global
example

function some_function () {
global $_GET;
echo   $_GET['year'];
}

NOT

function some_function () {
  echo   $_GET['year'];
}

[PHP] Re: session handling works on local server, but not when uploaded to ISP

[Bobby Patel]

It could be a warning in your script. On your local server, maybe you have
error reporting set to minimal (ie. don't report warnings), whereas the ISP
server might have it turned up higher by default.

near the top of your script reporter_view.php put in  the line
error_reporting(E_ALL); ie.
?php
error_reporting(E_ALL);
 PHP code
?

Maybe line 5 is causing a warning? After you have error_reporting on full
you may be able to solve the problem on your local server.

For more info checkout error_reporting() on php.net

Re: [PHP] Newbie and learning

I wanted to attach one more point (esp. since this is an ecomm solution),
you should also check your POST variables (in addition to the GET varaibles)
to make sure they are clean and what are expected. It's not that hard to
change posted values.

 PHP is, arguably, the better way to go when developing an ecomm solution.
 This list is full of very intelligent programmers that will help or direct
 you to the proper documentation.
 If you use $_GET you will be able to pass value pairs in the url.  Make
sure
 that in your data check script that you specifically assign variables to
 your $_GET in order to prevent malicious use.  $HTTP_POST_VARS is probably
a
 better way to go here.  Its cross platform and will almost guarantee that
 you will be able to use on any server.

 $HTTP_POST_VARS['name'];
 $HTTP_POST_VARS['email'];


 Good Luck!

  Hello All,
 
  I have been reading and digesting information from this list for about
two
  weeks now.
 
  I am doing some work and testing (both) and learning php on the way.
 
  Now I have seen several replies about using $_GET[] and $_POST[] and
that
  if you ARE sending variables using the URL you _should_ use $_GET[]
 whereas
  if you are _not_ passing variables in the URL you should use $_POST[].
 
  Is this correct?  I just want to make sure I have it in my mind so that
  when I start passing info via url I use the right method.  I ask this
  because I have a friend that wants to have me setup an e-commerce site
for
  him.  I am trying to decide if I should use ASP (gasp) or PHP (yeah).
It
  will be a db driven site which will have images in the db and probably
  multiple tables with inner and outer joins and search systems.
 
  Yes, I have the 4000+ (pdf) page manual on my system and refer to it and
  read sections of it at a time (chunk).  And I hope that I will be able
to
  answer most of my own questions there or in other resources before I
have
  to submit to the list.

[PHP] Re: Weird comparison error.

[Bobby Patel]

In PHP there are two operators for comparisons, the double and triple
equivalance.

Double equivalance just check's the boolean type so if (0 == 'n') is
translated to if (False == False), where as triple equivalance checks the
data types as well so if (0==='n') becomes if (Int(False)==String(False))
but since the data types don't match that would be False.

to get a better reference check PHP.net for 'Bolean Types' , because  I
think I dodn't explain the double equivalance right, and also it will
clarify situations of the Null type.

Rob Adams [EMAIL PROTECTED] wrote in message

 I don't need anything fixed, I'm just curious about something I noticed.

 I'm doing a comparison between a variable and a hard coded char.  Like
this:
 if ($k1 == n)

 The variable is usually the first key in an array (0) so it should usually
 evaluate false, but it was true every time until I changed it to:
 if ($k1 === n)

 So I'm assuming that it decided that since $k1 was an int to convert n
to
 an int (which would be 0) and conclude that 0 does indeed equal n.  So I
 decided for fun to try:
 if (n == $k1)

 And it still was true everytime.  So why does it always try convert my
 literal to an int instead of use the variable as a string?

 Just curious.  Thanks.

 I just started to dump my four $_SESSION-variables on top of every page,
 and to my big suprise they changes all the time.

 At login is store the users userid in $_SESSION['u_id']. At later times,
 I'm working with $_POST['u_id'] when for example changing administrators
 for different parts of the site. When I'm doing this, also
 $_SESSION['u_id'] changes.

 And at my localhost, $_SESSION's stays put.

[PHP] Re: nl2br and br /

[Bobby Patel]

Since I haven't had any problems with br / I really don't care. However,
if you are concerned why don't you write a function like this:

my_nl2br($targetStr, XML = true) {
$buffer = '';
if (XML) {
return nl2br($targetStr);
}
else {
$buffer = nl2br($targetStr);
$buffer = str_replace ('br /', 'br', $buffer );
return $buffer
}
}


You might be able to call the function nl2br but I am sure you will get  a
function name class or function re-declartion error, but if you are doing
some OOP then you may be able to overide that.

Maybe this is not the post you were looking for, anyways my 2 cents.

Bobby

Raymond C. Rodgers [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
 I'm sure that this has probably been discussed before, but I couldn't
 seem to find any direct references to such a discussion. The line break
 tags that nl2br() produces have the forward slash embedded in them,
 which is not in the HTML 4.x standard. While this isn't a big deal
 really, the fact of the matter is that web browsers built to the
 specifications of the W3C HTML 4.x standards may not like this. In fact
 the W3C HTML validator reports this as an error.

 I read on the function description page that this is apparently an XHTML
 curiosity. Would it be possible for someone to add an optional flag to
 nl2br() to specify HTML rather than XHTML compliance? For instance, a
 call to nl2br() without XHTML compliance might look like this:

 $mystring=nl2br($myotherstring,false);

 For compatibility's sake, maybe default the flag to true and make the
 flag optional. If unspecified, the call to nl2br() would continue to
 function as it always has. However if specified, and set to false, the
 function would return the HTML compliant break tag br.

 Thoughts? Comments?

Isn't Call-time pass-by-reference the following

Where as pass-be-reference is called as
$variable = myFunction2($x); Where is defined as function myFunction2

I think the latter is better anyways, because the caller shouldn't know the

  pass-by-reference has not been dropped, it is Call-time

 so call-time pass-by-reference is giving parameters as reference to
 functions, e.g.

 function returnObjectToAccumulator($obj) {...}

 If this feature is really dropped, how would you implement
 ConnectionPools for DB-connections for instance, or any classes
 managing a set of object and providing them by returning references?

 many OOP design patterns (primarily adopted from java) would not be

[Bobby Patel]

You can try using the cURL package with PHP. I use it with a system call.

$curl_path = /usr/bin/curl; # or full path of curl

$post = 'amount=3.40merchant_id=2351235'; #POST  key value pairs with ,
these variables will be POSTed to site

$command = $curl_path -d \$post\ $gateway_url;

exec($command, $responce);

the $responce variable holds any out put from the site.

Then you  will have to parse the HTML (which I hate).

The above technique is best for when the site you call post back variables
(thus no parsing).

Now, this is with PHP with no cURL package, if you have it installed than
maybe you can use the cURL Library to do the above.

I usually think that alot of rookie PHP programmers (I just started PHP a
year ago, myself) read the list, and the way I figure is that it is good to
make readers of the list aware of the issues of register globals.

Plus, after coding in both states of register globals, I personally like
explictly referring to the assoc array $HTTP_xxx_VARS to retrieve the
variable. Coders are familiar with magic numbers and we should stay away
from that, but to me register_globals seems like magic variables I look at
this variable and I think to myself Where did this variable come from?
(but that's just me).

  Correct, if you properly initialize your internal variables there is

  Then why has there been such a big deal about register_globals security?
  Is it because so much code is sloppy?

 From a robustness perspective, it is not a bad idea to be more explicit
 about where your user data is coming from and being able to easily
 distinguish user-oriented data from internal data.  What has been blown a
 bit out of proportion is the idea that you cannot possibly write secure
 code with register_globals on.  That is of course completely false, but
 you do have to be a little bit more careful which why the default was
 changed to error on the side of safety.

[PHP] (no) file creation by convert (ImageMagik)

[Bobby Patel]

I am working on creating a thumbnail script but the obsticle is that
'convert ' doesn't create a file from the script. I am doing a system call
with the following

?php
exec('convert -size 400x293 /home/original.gif -resize 8x8
/home/thumb.gif');
exec('cp /home/test1 /home/test2'); # Copying an existant file does work,
but calling convert to create a file doesn't
?

Where thumb.gif is the name of the new file to be created.

After I run this script, no file is created, however if I run it from the
command line (as httpd or any user) it works.

[PHP] Re: Text file breaking!

[Bobby Patel]

try this
$string = ereg_replace ('\r\n|\n|\r', 'br', $string);
OR
$string = nl2br($string);

NOTE: for me the first case will remove the newline, whereas the second will
keep them (It might be becuase of my old php version [4.06]?)

 Ok, I don't get it... I put a string to one line ( $string =
 str_replace(\n, br, $string); ) but when I put it in a text file I
see
 breaks right before br. For example:

 I have a text area and type:
 1
 22
 333

 then, I take that string and replace \n with br.
 $string = str_replace(\n, br, $string);

 then, I put the string in a txt file...
 and here's what I see in the text file:
 1
 br22
 br333

 instead of:
 1br22br333

 How can I make it that way?

Re: [PHP] RE: newbie alternate row colours in dynamic table

Hiya people

After a lot of soul searching, exploring the web and help from many people I 
came up with this simple solution:

Thank you Chris for explaining the toggle $colorset. In the end I decided 
this made life alot simplier.

(clearly the brackets have to be correctly aligned)

while( $row = mysql_fetch_array($db_result) )
{
echo(
tr $c
td . $row['bugid'] . /td
/tr
);
if ( !isset($c) )
{
$c = bgcolor=#FF;
echo $c;
}
else
{
unset($c);
}
}

Within the loop that prints the rows, whcih is usually a while loop. But

if ($colorset==0){
if ($trcolor=='#B0C4DE'){
$trcolor='#F0F8FF';}
}
print tr bgcolor='$trcolor';
}
I see that you are using a helping variable $colorset.
I have a problem reading your code in email, as i do not see hte indents 
well, so i restructure it here with _ underscores to make the indents 
survive the email program.

$trcolor=#F0F8FF; //1

while ($myrow = mysql_fetch_array($result))
{
___$colorset=0;
___if ($trcolor=='#F0F8FF')//1
___{$trcolor='#B0C4DE'; //2
$colorset=1;
___}
___if ($colorset==0)
___{ if ($trcolor=='#B0C4DE')   //2
__{$trcolor='#F0F8FF';   //1
__}
___}
print tr bgcolor='$trcolor';
}
Lets walk through.
In the 1st walk,
1a) you enter with color#1 and colorset=0.
2b) the first 'if' then sets it to color#2 and colorset=1
3c) The second if sees that both conditions are true and set the color back 
to color#1.

So the first row prints color1.

Ok. The code remembers the values, which are color#1 and colorset1.
In the next walkthrough,
2a) the colorset is set to 0 to start with.
At this moment you have the exact situation as with 1a).
do you see that? it would be much easier to see what is happening if you 
would have only colorset toggling its value and just before printing, 
decide what the color is as a result of the value of colorset.
Give it a try!

Basically:

$colorset=0;

while ()
{ toggle collorset (toggle: if 1 then 0 and opposite)
 if colorser=0 color=ff else color=a
 print color.
}

connect to mysql db and select all usernames from table user and place in 
the menu.

here what I have so far
?
$connection = db_connect();
$querystring = (select username from user);
$db_result = mysql_query($querystring);
(if mysql_num_rows($db_result))
{
 while ($row = mysql_fetch_row($db_result))
  {
 print(option value=\$row[0]\$row[0]/option);
  }
}
else
{
print(option value=\\No users created yet/option);
}

Any URLS will be much appreciated.

I need advice for an optimum solution to display the username that is logged

I have a header.php :
?
session_start();
echo BRfont face=\Verdana\font color=\red\size=\3\Logged in as: 
.$_SESSION['curr_user'].BR/fontbr;
?

Now I have many html forms which user's see
What I want to know is how to include the header.php into every html form 
page.

One way is to rename the html file with extension .php
then
?
require_once(header.php)
?
This seems a bit wasteful for one line of php to change all the forms to 
.php. Is there any other ways of embedding the header.php file in html 
forms.The reason I am so keen on keeping html and php files seperate is thus 
to make debugging easier and maintain a kinda three tier design.

Any suggestions will be much appreciated

[PHP] [Newbie] Password()

[Bobby Rahman]

Hi,

in my code I am trying to send an email (containing a password) to a user 
when he has forgotten his password.

The problem is that security leads to needing to encrypt passwords in the 
database. Im using the password function within mysql. Is there any way of 
reversing the password function() to get the original password to send out 
to the user?

Or are there any other suggestions in PHP to reverse encryption of 
passwords. I do understand the principles of encryption and can see the 
point of unreversible functions but Im sure that not all applications re-set 
passwords with random generated ones but do send out forgotten passwords.

Cheers

Re: [PHP] Passing variable from webpage to php (newbie?)

[Bobby Rahman]

Hiya

It could need setting register_globals =on in your php.ini

if after that still problems then you may need to look into sessions and in 
particular session_start() and $_SESSION['varname'] and make sure the 
variables are global so that more than one script can use them.

Hope this steers you in right direction
*warning im a newbie too so you may wait for some more replies to confirm

Date: Wed, 19 Mar 2003 10:57:11 -0500
I think I already tried to post once, so sorry if this is a duplicate, but 
I
don't see my first attempt.  I am trying to do what should be a relatively
simple and basic task.  I've got a php script/page that has a switch/case
selection statement in it.  Obviously, depending on what value a particular
variable takes when passed to the script, the script SHOULD :) do different
things.  However, when I invoke the script using
www.somedomain.com/somephpscript.php?action=1  (substitute one with, 2, 3, 
4
or whatever) and then do a check whether any value is passed to my script,
it always tells me the value is empty ( if (empty ($action)) - it just
always thinks its empty.  I'm copying this script from a book, so I do not
have any reason to believe there is an error in the code, but obviously
something is not happening properly.  My thought is that perhaps something
needs to be turned on in the php.ini or in the apache httpd.conf file to
allow this variable passing to work.  Is there some other way to do this?

Sorry for the long paragraph sentence.  I'll be happy to post the code if
needed or provide any additional information or give the actual URL so you
can see what is happening.
Thanks for any thoughts

[PHP] Re: Missing session vars when doing var_dump()

[Bobby Patel]

I would think that they are 16 key/value pairs when the MySQL (TEXT) fields
are null thus the session variables are NOT set thus NOT present.

Hypothsis: I believe that your are using mysql_fetch_array($query_resource),
try using the second parameter as well ie.
mysql_fetch_array($query_resource, TYPE_OF_ASSOCIATION) example
mysql_fetch_array($query_resource, MYSQL_ASSOC) (please see php.net for
details of mysql_fetch_array).

By using the second parameter, even NULL values will has a variable set.

Example say you had a field called FirstName in the MySQL database. If it
was NULL, then without the additional parameter you would have NO key named
'FirstName' exisiting (ie it is not set). But if you used the second
parameter a key would be created with no value (ie it is set but empty).

So remember, the second parameter is OPTIONAL, but it has different
behaviors when you do (and do not) use it. Hopefully I cleared it up (or at
least shed  some light).

 Hi

 I have come across a strange problem. I have an application that a user
 logs into and when I find the user in the database I load all the custom
 info for that use which I store. By the time I'm done, the session array
 has 18 key's. When I do a var_dump($_SESSION) I sometimes get
 18 variables and sometimes I only get 16. The two fields that are missing
 are TEXT fields from a MySQL database and they also appear to be
 the last two keys when var_dump() returns all 18 keys.

 Does anyone know what is causing this, it's driving me crazy at the

Re: [PHP] Re: Missing session vars when doing var_dump()

[Bobby Patel]

If you it's either ALL or Nothing then I would think it has something to do
with retrieving sessions from the client (in the form of the cookie) or on
the server (in the form of the session file, default is /tmp on *nix
systems).  I ran your script on my server where I have session varaibles and
I never had a problem.

I'm out of ideas now.

 Hi Bobby

 The following is a copy and paste of the page I'm using to
 generate the problem. I have 18 keys in the $_SESSION
 variable and just by simply refreshing the page with the
 following code, it returns either array(0){} or session info and
 array(18){ will all the correct variables }. I must be doing
 something fundamentally wrong somewhere.

 Thanks very much for your willingness to help me.

 foreach( $_SESSION as $key = $value )

 var_dump( $_SESSION );

I would think that they are 16 key/value pairs when the MySQL (TEXT)
fields
are null thus the session variables are NOT set thus NOT present.
   
Hypothsis: I believe that your are using
mysql_fetch_array($query_resource),
try using the second parameter as well ie.
mysql_fetch_array($query_resource, TYPE_OF_ASSOCIATION) example
mysql_fetch_array($query_resource, MYSQL_ASSOC) (please see php.net
  for
details of mysql_fetch_array).
   
By using the second parameter, even NULL values will has a variable
  set.
   
Example say you had a field called FirstName in the MySQL database.
If
  it
was NULL, then without the additional parameter you would have NO
key
named
'FirstName' exisiting (ie it is not set). But if you used the second
parameter a key would be created with no value (ie it is set but
  empty).
   
So remember, the second parameter is OPTIONAL, but it has different
behaviors when you do (and do not) use it. Hopefully I cleared it up
  (or
at
least shed  some light).

[PHP] Re: Passing variable from webpage to php (newbie?)

[Bobby Patel]

You have register_globals set to off (read up on register globals in
php.net).
your code should read
$HTTP_POST_VARS['action'] or $_POST['action'] (depending on PHP version)
INSTEAD of just $action.

so to test an if::
if ($HTTP_POST_VARS['action']==1) {
/*
Code for if action is equal to 1
*/
}

Of course checkingif the variable is set or empty might be a good idea as
well, is set example:
if (isset($HTTP_POST_VARS['action'])) {
/*
Code if the variable POSTed is set
*/
}

different
 things.  However, when I invoke the script using
 www.somedomain.com/somephpscript.php?action=1  (substitute one with, 2, 3,

 it always tells me the value is empty ( if (empty ($action)) - it just
 always thinks its empty.  I'm copying this script from a book, so I do not
 have any reason to believe there is an error in the code, but obviously
 something is not happening properly.  My thought is that perhaps something
 needs to be turned on in the php.ini or in the apache httpd.conf file to
 allow this variable passing to work.  Is there some other way to do this?

 Sorry for the long paragraph sentence.  I'll be happy to post the code if

 admin's see other things, but I can't seem to pull the information out
 of the database.

 Here is part of what I have.

 $query = select * from users where username='$username' and

 $num = mysql_num_rows($result);

 $row = mysql_fetch_array($result);

 $_SESSION['valid_user'] = $username;
 $valid_user = $_SESSION['valid_user'];
 }

 Now if I tell it to print $valid_user, it shows the user logged in, but
 if I try to print $user_type I don't get anything in return. Any ideas
 as to what I am doing wrong? I have tried a separate query for the
 mysql_fetch_array, and that didn't seem to work either.

[PHP] Re: Checking for Null Variables

[Bobby Patel]

you can look at isset() and empty(). If you retrieve the query result with
Mysql association (ie. $field=mysql_fetch_array($resource, MYSQL_ASSOC),
then even the field has a blank value, there will be a blank variable
created ($field[Name] is created but with no value)), however if you grab
the resource values as such $field=mysql_fetch_array($resource), then a
blank field will not create a $field[Name].

So, if using :
$field=mysql_fetch_array($resource, MYSQL_ASSOC)
 if(empty($field[Name])) { do this }
 else { do this }

OR
$field=mysql_fetch_array($resource)
 if(!isset($field[Name])) { do this }
 else { do this }

 It does not work right. Actually, at one point, it was working in the

 create the INSERT statement? I feel this will be awkward due to the

 anyone's input. The form names are the same as the field alues in the
 table...

 It will need to be something like

 $query = 

 while (more Form Fields){
 $query = $query + 'form fieldname';
 }

 $query = $query + ) VALUES (;

 while (more POST Values){
 $query = $query + POST Value;

 log-in page like this:

 include_once(function_library.php);
 session_start();

 if (!LoggedIn()) {  // If not logged in, take to Login page.
 header(Location: /login.php);
 }

 LogAccess($_SESSION['user']);  // This function logs user's access.


 I noticed that the LogAccess() function I have after the header() redirect
 is executing, even if the user is not logged in and is redirected to the
 Log-In page. I did confirm that the LoggedIn() custom function is working
 properly and returning the right value.

 I thought the code below the header() redirect would not actually be
 executed unless the user was logged in and allowed to proceed. Is this how
 PHP is supposed to work? Is there any way to prevent the script from
 executing below a certain point if the user is not logged in?

 Thanks,

I believe PHP and MySQL use two different definitions of the start of a time

strtotime($attributes[startdate]) ,  UNIX_TIMESTAMP (datestamp)

Also, in your query you are looking for all headlines that have

two strtotime($attributes[startdate]) but not an 'end date '

As the previous post of using die would be better. Also try using

more than one query per script execution, then DON'T keeping trying to
connect/select database.

I suggest you do the first two things at the start of ALL the scripts that
will need to connect to the database, so make an include file with 2 things
(connecting and selecting a database). Then make another function just for
queries, this way on the second and onward queries will save overhead some

[PHP] Re: Passing emails to database

[Bobby Patel]

I have an idea that might work in theory. Provided that you have php running
on a Unix based OS. You could forward all emails to an email that sits on a
Unix server. There they are stored as plain text files, then just parse what
you need on a daily basis and truncate that file to 0 bytes.

BUT it sounds that you have the whole setup on a Windows based
machine/server.  If you can get access to PHP and Mysql on a unix server
then you will have a chance.

I just did a quick check on the PC and it seems that Outlook express creates
files with a DBX extension to hold email folders.
I found mine at C:\WINDOWS\Application Data\Identities\{JIBBERISH
HEX}\Microsoft\Outlook Express. Try anyalsing these dbx files (open them up
in a text editor). But there HUGE even just if they have one message in
them.

good luck

what did you chmod the file to? who owns the file? and what user does PHP

Just to get it to work chmod the file to 777, BUT this is a security risk.
MAKE SURE this file is NOT in the web folder (or any of it's subfolders).
Remember to write to a file PHP (the user nobody or httpd) also needs Read

is created.  Then when they logout, and the sesion is destoyed get the
current time stamp again and minus it from the start time.

Note: This requires the user to login and logout, if they just close the
browser then they will never get to your logour script, thus you can't
calculate their money owed.

 Got a quick and easy question that I'm not sure about. What I need to do
is
 calculate how long someone has been in a chatroom, then update a members
 table to add some money to their account. Something like this:

 For every hour they're in the chatroom: 5 cents

[PHP] Re: Read file and get what i want

[Bobby Patel]

Check out explode()
$file // say this variable has your file contents
$lines = explode (\n, $file); // lines contains each line of the file

foreach ($lines as $line - $content) {
if (strrpos($line, ':')) {
$values = explode (':', $content);
echo The first value is : .$values[0];
}
else {
echo This line doesn't contain a : moving to next line;
}

}


NOTE: if \n doesn't work try \r\n , I think. Also this is mostly from
the top of my head so there might be some syntax problems.

[PHP] Re: Session Variables

[Bobby Patel]

This variable is registered in the Session, and the variable isn't active
until the page refreshes.  It's hard to explain. I thought I would try.
There are some things you can do. If you need the variable right away, you
can do this:
if (isset($HTTP_SESSION_VARS[user1])) {
$user1 = $HTTP_SESSION_VARS[user1];
}
else {
$user1  = $HTTP_POST_VARS[user1];
}
echo $user1;

Hope that helps. This is natural for sessions, but I have been in the
situation where I needed the session variable right away, instead of the
script's next activation.

[PHP] Re: Multiplication of double

It seems you have register globals set to off, thus when you have variables
$price and $qty they are just fresh variables, you might try
$HTTP_POST_VARS['price'] and $HTTP_POST_VARS['qty'] (don't forget the single
quote).

I have done something similar:

Skelton for getArticle.php
- take id and store in $id
- Select FullBody from Articles where ID = $id
- $body = query['FullBody']
- then echo $body

That's the basic idea, if you have any problems email me and post to the

Re: [PHP] Re: Images : Store in dB or disk?

[Bobby Patel]

That makes sense. When Marek explained it I didn't realise that IMG tags
can't use the raw data, and needs to make a seperate HTTP request for the
Headers.

Now, I understand. Unfortunately the desicion has been made to go with the
database.

Oh well, I can always code the scripts to store and grab from the
filesystem, after if need be.

Thank you everyone, who has responded.

 Hopefully you've gotten the point that this isn't true. If you store
 your images in the database, it's going to make your main script execute
 one query to output something like img src=file.php?id=xxx
 ...properties... for each image. Each one of those img tags will be a
 separate request where file.php would pull the data for _one_ image,
 send the headers and then send the data.

[PHP] Re: Question about using session and logging out

[Bobby Patel]

I believe there something (a meta tag?) called  meta-refresh or just
refresh.

But I believe you have to set the refresh interval. and if you set the
interval to small it might eat your server's resources.

OR I just thought of this, sometimes when you get to a page (usually with
forms?) it says that the page is expired and must be refreshed. Maybe you
can get that behaviour, so that when someone hits back, they have to
refresh.

Hi,

I have an application that uses sessions to allow customers to access a
restricted area.  That is, they are prompted for a user login and password.
I then use sessions to track each customer.  At the top of each page, I have
placed the following PHP code:

session_cache_limiter('Cache-control: private');
session_start();

Everything works fine.  However, I have a logout link that when clicked,
runs the following PHP code (where userid is the login name):

session_cache_limiter('nocache');
if (isset($HTTP_SESSION_VARS['userid'])) {
   $HTTP_SESSION_VARS['userid'] = '';
   session_unregister($HTTP_SESSION_VARS['userid']);
}
session_unset();
session_destroy();
Header('Location: ' . 'http://www.lclnav.com' . $globals-relative_path .
'customerlogin_standard.html');

I think the above is all that is needed to end the session.  I use the
Header() function to take the user back to the login  page.

Here is my question:  Once I click on the logout link and am taken back to
the main login page, I can click on the browser BACK button and still get my
previous page 'as if I was still logged in'.  Please note that clicking on
REFRESH tells me that I am not really logged in.

I know that browsers cache pages and there may not be anything I can do,
however, I have seen sites that seem to work around this; i.e.., clicking on
the back button loads a pages telling the user that they are no longer
logged in.  This is what I want to emulate.  Is there a PHP method to always
force a reload the first time a page is called?

Thanks,
Don

 Hello,
 I have the Images table setup with columns (width, height, size, type,

 disk?

 I know, alot of people have said it is faster in disk, which is 1 page
I/O.
 But I need these images for displaying product pages, and I believe that
it
 would be faster to just pluck the properties from the dB (including the
 image file) .

 Usually I will need to pull 6 or 10 images per page, this is my rational
for
 this situation:

 If all stored on db:
 One query  - will take about 4-5 page I/O (assumiing index on filename)

 If just properties stored on dB and image on disk:
 One query to grab the rows of properties - 2-3 page I/O
 to grab 6 or 10 images - 6 or 10 page I/O
 Total - 8 - 13 Page I/O's

 If all images stored on disk, no dB whatso ever:
 to grab 6 or 10 images - 6 or 10 page I/O
 cpu time to run getimagesize()  for each image - CPU time unknown?

 I assume that page I/O is that same as disk access.

 I AGREE that storing images strored on disk is a valid approach PROVIDED
 that you only need 1 image per page, but if you need to grab a bunch at a
 time, I do beleieve that storing the actual file on the dB is faster.

 I would like to hear from the list, of people that have worked with images

Re: [PHP] Images : Store in dB or disk?

[Bobby Patel]

It looks nice. It does take a couple of seconds, (but I guess that is to be
expected with dealing with images).
I guess seeing your example, it seems that I can go with the filesystem. But
do you use the getimagezise function? do you set the width and height for
the IMG tag dynamically, or you don't use the image function and just have
the IMG tags already set in stone?

[EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
 Have a look at:

 http://vrscenes.com/2003/gallery.php?mls=230944

 and tell me what you think - all images are stored in the filesystem

 Don't worry about what it looks like - I extracted this from the frameset
it goes in

[Bobby Patel]

I was trying to do it without cURL, since it's not on our server. I guess
I'll just install it, and just use that. I checked out snoopy but when it
gets down to it, it just uses cURL, so I rather just use cURL directly and
cut the fat (of code that is).

 Have a look at curl and snoopy.

Re: [PHP] Password Script

[Bobby Patel]

If you have access to a database on your server then you can do the
following:
- user logs in to site (user enters unique username and password)
- once in they will be displayed with the 3-6 Questions
- after they answer the questions they hit submit which sends it to a PHP
script
- the PHP script will check a table in the database for the username and
increment a counter
- then if the counter is less than 10 then validate questions for right
answer, .then you understand the rest

[PHP] Re: dynamic variable headache

[Bobby Patel]

try this:
$mmdd  = $foo.$bar.$bleh.$doh; /*note double-quotes and the concat
operator (the period) */
$$mmdd  = a_date_value;

To test;
echo $mmdd ;
echo $$mmdd;  /*provided that a_date_value is a string literal*/

My newbie brain is maxed out on this, and I'm sure one of you more
experience guys can quickly straighten me out.

I've got a variable:

$_mmdd =  a_date_value;

Later, I've got four variables;

$foo= _;
$bar=;
$bleh=mm;
$doh=dd;

I want to stick these variables together on the fly to get _mmdd  and
use that value as a variable name to return a_date_value.

It would be the equivalent of,

echo $foo$bar$bleh$doh;

That would give me a_date_value

I've read the docs on dynamic variables but still can't seem to break
through mentally on this one.  Can you clear this up for me?

Thanks in advance.

[PHP] Office XP pro - email attachments

[Bobby]

Hello, I know XP (argh...)
Anyways, I written a script where a user can upload a gif or jpeg and then I
email it to an email address. Now, everything works fine, the reciever can
view the attachments in Squirell Mail, Outlook Express, and Outlook (both
are Office 2000  versions). But under outlook for Office XP pro, it doesn't
even display that there is an attachment. I was wondering, are there some
email headers that I must send as well for XP to see it? Also, Outlook Xp
can see email attachments when I send from an email client so I don't think
it's a Xp settings issue.

[PHP] Problem with function declaration in include files

[Bobby]

I have been using the following function declaration syntax for ages with no
problems.

Main php file:

?php
include my-inc.php;
...
FuncExample(arg1,arg2);
...
?


Include file:

?php
...
FuncExample(arg1,arg2){
Function Content
}
...
?php

I have just finished some work for a client, after full testing on both my
Unix and Win32 test servers I moved the site over to their hosting company
and I get the following problem.

All my functions that are declared in my Inc files are spitting back the
error:

Fatal error: Call to undefined function:...

I have spoken with the hosting company, but they have considerable trouble
with 'backside' and 'elbow' recognition.

Are there any PHP.ini settings that affect this type of function
declaration?

Any help would be appreciated.

Bobby

Re: [PHP] Problem with function declaration in include files

[Bobby]

I wish it was that simple, I have already added debug 'echo' statements to
make sure the included file is being included correctly and it is?

This problem really has me beat, I never usually send out desperate pleas,
but I am not a happy bunny atm.

Any thoughts would be appreciated

Cheers

The problem is most likely with your include statement.  The include path
imay be incorrect...
