[PHP] How to print nice looking text on an image?
Hello, I am producing a script that writes text onto a JPEG image to create custom printable gift certificates for an online store. The basics of the scripts are straight forward. However I found that the imagestring() function produces absolutely horrible looking pixelized text and on these gift certificates looks are important. I attempted to employ the imagepstext() family of functions but they do not appear to be installed on this account (it's a shared server), I'm getting call to undefined function errors. So my question is; Is there any other way to produce good looking anti-aliased text on an image? I'd appreciate any information, classes and links to guides you can point me to. Thanks!

RE: [PHP] preg question
The period is a modifier within the expression (see manual on pattern
syntax link below). You need to escape it with a back slash:

Hi all,
I am trying to do a simple validation of an email address being
submitted. I have the @ sign being validated, but I can't get the
period to work.. Can someone help me out?
Here's my code..
if ($_POST['Travel_Request_Email_Address'] != )
{
if (preg_match_all(/(@)/,
$_POST['Travel_Request_Email_Address'], $match) != 1)
{
$errorcount++;
$error = $error . nbsp;nbsp;nbsp;nbsp; . $errorcount .)
font color=\red\Email Address/font field does not contain @br
\n;
}
else if (preg_match_all(/(.)/,
$_POST['Travel_Request_Email_Address'], $match) 1)
{
$errorcount++;
$error = $error . nbsp;nbsp;nbsp;nbsp; . $errorcount .)
font color=\red\Email Address/font field does not contain .br
\n;
}
else
{
$_SESSION['Travel_Request_Email_Address'] =

[PHP] Re: header() refresh vs location
The Refresh directive is a valid header. I've used it for many years and it seems to
be supported by the majority of browsers. However I've never read anything that would
indicate that Refresh works any differently than Location. The only difference is
that Refresh allows you to set a number of seconds before redirecting to the given
URL. As to whether or not it will solve your problem is something only you can answer.

Chris Hubbard [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]
All,
I have done a number of searches.
I have read the online documentation and user supplied comments.
I recently ran into problem using:
-some code here to create session and set variables-
header('Location: index.php');
where the sessions would sometimes get lost, they wouldn't make it to the
index.php page. A print_r on $_SESSION would display an empty array. And
yes the sessions are getting set properly. The same code works on three
different servers, with no modifications.
So a friend recommended using:
header (Refresh: 0; url=index.php);
I haven't seen documentation for refresh in the header function. Is there
any reason to use one in lieu of the other? Any comments on 'refresh'?
As I said, I've looked at the online documentation:
this page: http://us4.php.net/manual/en/function.header.php doesn't have the
word refresh on it.
this page: http://www.w3.org/Protocols/rfc2616/rfc2616 doesn't have the word
refresh on it.
this page: http://us4.php.net/manual/en/function.headers-sent.php does have
the word refresh but it's not relevant.
Thanks in advance.

[PHP] Re: header() function for displaying an opened PDF document.
I'm sorry but it can't be done. You cannot output a file without printing it to the output buffer. You cannot print a file to the output buffer without opening the file into memory. You cannot open a file into memory without using a function like fopen() or readfile(). It's as simple as that. There must be something wrong with Internet Explorer on your end. Corrupt files perhaps? Try installing the latest update, or use system restore to go back a few weeks, or reinstall the components from the Windows CD. That's my best advice. But I guarentee this is not a PHP problem and that there is no work around for it other than to fix what's wrong on your system. Good luck. Once everything is working you will see the PDF open in the browser plugin when you set the Content-type header. And you should see a download prompt when you set the Content-disposition header. - Kevin Scott Fletcher [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I can't do readfile() because of lots of bug in IE (Internet Explorer) Kevin Stone [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Forget the content length and disposition headers.

Hello Everyone,
I am trying to display a JPG image to a use, who has logged in. Some
research on google revealed a way to do this. I am using the following
code to display it.
if (session_is_registered(valid_user)){
if(session_is_registered(cmi)){
header(Content-type: image/jpg);
$file = docs/picture1.jpg;
header(Content-disposition: attachment; filename=$file );
readfile($file);
}
My question is that while this approach works fine with Mozilla on the
MAC and Win platform. it throws up a dialog box asking whether the user
wants to download the file or view it. However IE on either platforms
does not work fine. On the PC it does not recognize the file extension
correctly. While on the MAC side of things, it just shows the image in
the same frame.
Any suggestions would be most welcome. !

Too much pittfals and too slow! Really the socket connection only
retreiving the headers is really the best way.
This function is what you need:
function fileStamp($domain, $file)
{
$file = / . $file;
$fp = fsockopen ($domain, 80, $errno, $errstr, 30);
$header = HEAD $file HTTP/1.0\r\nHost: $domain\r\n\r\n;
if (!$fp){
echo $errstr ($errno);
return false;
}
fputs ($fp, $header);
while (!feof($fp)) {
$output .= fgets ($fp,128);
}
fclose ($fp);
$begin = strpos($output, Last-Modified: ) + 15;
if($begin==15) //no last-modified (like yahoo.com)
return false;
$end = strpos($output, \n, $begin);
$time = substr($output, $begin, $end-$begin-1);
return strtotime($time);
}
Polleke
Slow? Hogwash. You're pining over microseconds. Besides most of the time is taken
opening the file which you're doing anyway. Except that the socket method relies on
header information that may or may not be there. I agree it would be ideal if you
could use that information but your fileStamp() function isn't going to work for all
files on all servers.

[PHP] Re: Central authentication for multiple sites
If all domains have access to the same database then there is absolutely nothing preventing you from using a Cookie. Have a normal login on Domain1.com. Once authenticated produce a random ID and store it in the database. Store the ID in a cookie then Redirect the client to the desired domain. The page the client is redirected to checks to see if the ID matches one stored in the database. If it does then the user is valid. A logout request on any one of the domains destroys the ID in the database and erases the cookie. Associate a timestamp with the ID in the database so that you can make the login invalid after a period of no activity. - Kevin Fraser Campbell [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, Does anyone know of a way to authenticate a person on one site and have that authentication carried through to multiple sites?

I'm sure there's more than one viewpoint out there, so I'd like to hear a couple of them. Is this frequent mode switching good, bad, or indifferent? Is there a point at which the mode switching starts to seriously degrade performance and reliability? -Derrick I used to program that way. The logic and presentation portions of my scripts were combined into one or two monolithic files. That worked well for small projects. But as I got involved in larger projects and had to juggle many code files at once I found that I prefered to separate as much of the HTML from the PHP code as possible. Typically what I do now is set up my HTML in a template-like format using ?= $var? as the outputs. Very little logic goes between the ?php? tags in my HTML files but of course sometimes it's unaviodable and that's why you want to use ?php? tags here and not some phoney template language. Then sipmly include() the HTML file back into the script allowing the outputs to fill in. This makes for a very 'plastic' interface that you can mold very easily in an HTML editor without screwing up your script. For example I did a calendar script recently with the following outputs... $next_year $prev_year $cur_year $cur_month $cur_day $january $february $march $april $may $june $july $august $september $october $november $december $event_list $event_header Each output contains a portion of the final calendar page. So I could take the months and put them into rows or columns, take the event list and put it on the top or the bottom, take the interface elements and place them where they work best. Or I can ignore half of the outputs and display only one month if I wanted to. Point being I could do this in a fraction of the time it would take me to do it in logic portion of the script.

[PHP] Re: why doesn't default values for this function work
Anders Thoresson [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
Hi,
I'm having problem with a function that I'll use to validate user input
before passing it to MySQL. For strings, I want to make sure that they
aren't to long, so I have written this function:
function secure_string($unsafe_string, $max_length = -1, $errormessage =
Too many characters. ) */ { // verify that string isn't longer then
$max_length, if $max_length is set if ($max_length -1) { if
(!is_int($max_length)) { error(Variable max_length is not an integer. );
} if (strlen($unsafe_string) $max_length) { error($errormessage); } }
...
and the validation will continue here.
When I want to use the max length check I pass a value to the function
like
this:
$a_header = secure_string($_POST['a_header'], 60, Header must not be more
then 60 characters. );
But I having to problems:
1) If no max length is passed, and $max_length gets the value -1, the if-
loop if ($max_length -1) is still run.
2) Calls to my own function error doesn't work. Instead of creating a
popupwindow with javascript (which works in other places where error() is
called) the errormessage is printed like html.
What's wrong?
Best regards,

Having trouble with your line wrap?
Okay.. from what I can decipher you have a logic error starting with the
first if() statement. You've set a default value of -1 and then you're
testing if the input is greater than -1. However if the variable Is Set but
Empty the input will evaluate to 0 which is greater than -1 and the
condition will be true. This is what Jason was talking about but it's only
half the problem.
The other thing is if you're going to use the default value then the
is_int() statement should come *before* the value comparison. But you
should not need the default value at all becuase your're testing the
validity of $max_length against the length of the string later in the
function. Provided you know that the value is an integer and less than
$max_length then any testing beyond that is just redundant nonsense.
So fortunately all you need to do is eliminate the default value along with
the first if() statement and you should be good to go..
function secure_string($unsafe_string, $max_length)
{
if(!is_int($max_length))
error(Variable max_length is not an integer. );
if (strlen($unsafe_string) $max_length)
error(Too many characters.);
}

$result = mysql_query($sql, $connect); //-- like this
The reason you may be seeing 1 instead of the value you expected is that the

Why? AFAIK, exit quits the script, exactly what you want if you want to

---
Zerof, Comex is absolutely correct. exit() should almost always be used in
conjucntion with header(Location: ). I would be interested in learning
what collateral effects you see when doing so. By any logic exit()
should reduce the number of adverse effects when using header() redirects.
Consider this example..
?
if($i==10){
header(Location: $nextpage);
}
$_SESSION['i'] = $i;
?
If we were to employ this code $i would be set to the session even if
header() was called and the user was redirected. PHP does not care that
another script has been launched and happily continues to execute this
script. Is this really a desirable effect? No.. surely not. Instead what
we should do is exit the script after redirecting the user.
?
if($i==10) {
header(Location: $nextpage);
exit;
}
$_SESSION['i'] = $i;
?
Now we're safe becuase nothing beyond the header() call is going to execute.
Obviously this is an extraordinarily simple example. But most scripts are
not so straight forward. If you don't exit after a header redirect you
could be causing yourself one hell of a headache.
Be wise and have one script running at one time.

You can use the HTTP_REFERRER, but i wouldn't depend on it, it isn't a

what you prolbably should do is when the arn't logged int, you can send
them to something like:
header('location: login.php?next=a.php');
Then on your login form add a hidden variable:
input type=hidden name=next value=?echo $_GET['next']?
Finally when the user submits this form, and the user logs in
successfully you know that you need to redirect them to the a.php.

Umm.. well.. '$name' is a litteral inside the string until it is evaluated.
It doesn't matter if you make a copy of the variable, '$name' is still going
to be a litteral value. So you'll have to eval() it exactly the same way
every time. But maybe I can offer an alternative...
You look at this string and see a code evaluation problem. I look at this
string and see a find and replace problem. Consider useing str_replace()
to search for and replace '$name' as a template marker rather than a
variable to be evaluated..
$data = 'hi my name is $name';
$name = 'Shawn';
echo str_replace('$name', $name, $data);
This accomplishes exactly the same thing and it's a perfectly valid form.
Plus it's going to work on any string becuase you don't have to turn them
into PHP code first.

Worth a try. Ideally you should have an additional column with an autoincrementing value to act as your primary key and you delete on that key. - Kevin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Subject: [PHP] Session Problem
Hi,
I am getting a weird session problem in my site.
Background of the Problem:
--
My site use sessions for user authentication. Site has a Admin Panel where
admin can search users and then through a link
(which has login and password appended) login as user.
On login as user, session var changes to the new user vars, like user id
etc. So, if some one try to access any thing on
admin panel, they get error which is quite evident why is that happened.
The
login user is not a admin any more, its a normal
user with no privilege.
I came to a conclusion that if I spawn new browser window it takes old
session. After trying for hours, I was able to solve
this. I started a new session when I login as user by setting session name
and storing the other vars. This way I can start
the session as needed.
After solving this problem I thought I am done. But some thing really
weird
popped up. The links on the page, like My
Account, Change Password goes to admin when I click them. This looks
like
on clicking the link, Old admin session becoming
active and showing the page as a admin. I have no idea why is that
happening. I have searched goggle but no result.
Is it a browser issue, or php issue, or I am doing something wrong.
* I have compiled PHP with trans-sid option.
** I store session in my sql database. I can see the user session active.
Ideal Solution:-)
--
When I search the user and login as user. Both admin and user session
remain
alive and I can work on both windows seamlessly.
Can Any one point me in the right direction.
Thanks
This is a problem that many of us have had to deal with.. Session ID's
caching and revalidating when the back button is used or a page is
revisited. The solution is simple. Don't just destroy the Session, also
write over all variables within the session like this..
foreach($_SESSION as $key = $val)
{
$_SESSION[$key] = '';
}
The next time session_start() is called the session file will be emptied.
This will ensure that if you click the back button and the Session ID has
been cached the session file no longer contains any useful data and there is
no possibility that your Login script will revalidate the user.
Quite frankly I wouldn't even bother using session_destroy(). It doesn't
seem to do anything useful.
Good luck,
Kevin

I'm trying to understand how the code works within the preg_replace

but the manual is just obscure as the examples are. Anyway, I am looking
to
use it to replace \\ in a string with / and I can not figure how how.
At first, I thought I could just do:
$filevalue = preg_replace('\\', /, $filevalue);
but it doesn't do anything. If someone could relate what it is and what
the
parts mean between the (), I would appreciate it.
thanks
You're not using the function correctly. You've got the search string and
replace string tied up into one input there. They need to be separate.
$filevalue = preg_replace('\\', '/', $filevalue);
http://www.php.net/manual/en/function.preg-replace.php
However you should consider using the str_replace() function in your case
since you aren't doing any pattern matching and it's a lot faster than
preg_replace().
$filevalue = str_replace('\\'. '/', $filevalue);

Re: [PHP] Table trouble
I'd just dump all of the results into an array and do something like this:
echo table border=1\n;
for($i=0; $icount($array);)
{
echo \ttr\n;
for($j=0; $j2; $j++)
{
echo \t\ttd.$array[$i]./td\n;
$i++;
}
echo \t/tr\n;
}
echo /table\n;
On odd numbered arrays you'll end up with an empty cell. Most browsers will
handel the empty cell by simply not displaying it. Others might show the
box. It's a minor cosmetic thing but if you want it to look consistent then
test for that situation and add a non-breaking space to the final cell.

Subject: Re: [PHP] clearing cache
I can't just create a link on the last page back to the first page.
Because
if the user hits the back button on the browser they end up on page 2.
Which can't happen. Once you are on the last page the user can't by
anyway
get back to page 2, unless they start over on page 1.
What I am planning on doing is passing the variables using the POST
method.
Then have a hidden variable pass with the pages. If this hidden variable
is
missing then redirect the user back to page 1. Thus if I can get page 2
to
be cleared from the browsers cache after it has been displayed, if the
user
came back to this page using the back button the page will be reload from
the server because it is not in cache, there for my code will not find the
hidden variable and redirect the user back to page 1.
I think the theory of this will work ok, but I don't know how to clear a
page from the browsers cache after it is displayed.
Thanks,
Mark.
[SNIP]
Mark, this is kind of a lame hack but give it a try...
/** PAGE A (first form) **/
?
session_start();
if (isset($_POST['submit'])) {
header(Location: test3.php);
exit;
}
?
/** PAGE B (second form) **/
?
session_start();
if ($_SESSION['startover']) {
$_SESSION['startover'] = false;
header(Location: test2.php);
exit;
}
if (isset($_POST['submit'])) {
header(Location: test4.php);
exit;
}
?
/** PAGE C (results page) **/
?
session_start();
$_SESSION['startover'] = true;
?
The idea is to keep a startover variable in the session. The variable is
set when you reach Page C (the results page). When the user hits the back
button the variable is tested on Page B for true or false. If it's true
header() redirect back to Page A. Otherwise it prints and/or validates the
form on Page B.
Why header() redirect between each page? Becuase it overwrites the post
data allowing you to use your back button without a repost. This results in
a much cleaner more controlable user interface. If you need to pass form
data between forms then simply store the post data in the Session and
extract it on the next page.
If I'm right, what you're going to see in the browser's back button history
using this method is a single instance of PAGE A repeated for each cycle.
Good luck with this.

[PHP] How to avoid Socket Post output?
Hello list,
I'm attempting to use the PostToHost() function to send a request to a
remote script. The purpose for this is to request and retrieve information
from a remote database without the need for messy HTTP HTML methods. I
realize that I could use an HTML form, put the data in hidden fields, and
send the request that way, but then I would have to redirect back from the
master script recording an unwanted page in the 'Back Button' history. I'd
like to avoid that so I'm investigating methods of POST'ing through a manual
socket connection.
Here is that PostToHost() function..
/*
PostToHost($host, $path, $data_to_send)
$host; valid domain (ie. www.domain.com)
$path; relative URL (ie. /myfile.php)
$data_to_send; urlencoded key/val string (ie.
key=valkey2=val2key3=val3)
*/
function PostToHost($host, $path, $data_to_send)
{
ob_end_flush();
$fp = fsockopen($host,80);
fputs($fp, POST $path HTTP/1.0\n);
fputs($fp, Host: $host\n);
fputs($fp, Content-type: application/x-www-form-urlencoded\n);
fputs($fp, Content-length: . strlen($data_to_send) . \n);
fputs($fp, Connection: close\n\n);
fputs($fp, $data_to_send);
while(!feof($fp))
{
echo fgets($fp, 128);
}
fclose($fp);
}
It works great! The only problem is I get output from the socket connection
and I don't know how to skip over it...
HTTP/1.1 200 OK
Date: Mon, 16 Jun 2003 20:10:36 GMT
Server: Apache/1.3.20 (Unix) ApacheJServ/1.1.2 PHP/4.2.3
FrontPage/5.0.2.2510 Rewrit/1.1a
X-Powered-By: PHP/4.2.3
Connection: close
Content-Type: text/html
I'm very much a newbie to all of this so you'll have to forgive me. But I'm
wondering if there is anyway to avoid this output and have a completely
invisible manual socket POST?

Re: [PHP] How to avoid Socket Post output?
Oh wait.. unless that output is required somehow. I removed the echo
statement now my request isn't being replied to by the database script.
Seems I desparately need a lesson in socket connections. Does anyone know
of a good book or tutorial other than the manual that goes into this stuff
in depth?

Subject: [PHP] How to avoid Socket Post output?
Hello list,
I'm attempting to use the PostToHost() function to send a request to a
remote script. The purpose for this is to request and retrieve
information
from a remote database without the need for messy HTTP HTML methods.
I
realize that I could use an HTML form, put the data in hidden fields,
and
send the request that way, but then I would have to redirect back from
the
master script recording an unwanted page in the 'Back Button' history.
I'd
like to avoid that so I'm investigating methods of POST'ing through a
manual
socket connection.
Here is that PostToHost() function..
/*
PostToHost($host, $path, $data_to_send)
$host; valid domain (ie. www.domain.com)
$path; relative URL (ie. /myfile.php)
$data_to_send; urlencoded key/val string (ie.
key=valkey2=val2key3=val3)
*/
function PostToHost($host, $path, $data_to_send)
{
ob_end_flush();
$fp = fsockopen($host,80);
fputs($fp, POST $path HTTP/1.0\n);
fputs($fp, Host: $host\n);
fputs($fp, Content-type: application/x-www-form-urlencoded\n);
fputs($fp, Content-length: . strlen($data_to_send) . \n);
fputs($fp, Connection: close\n\n);
fputs($fp, $data_to_send);
while(!feof($fp))
{
echo fgets($fp, 128);
}
fclose($fp);
}
It works great! The only problem is I get output from the socket
connection
and I don't know how to skip over it...

- Kevin
After brainstorming and experimenting for about an hour I found that I was
able to get by with a dirty hack. I do an ereg match for each line that
comprises the server info being outputed. These lines are not required for
the request to work so if the output matches one of the values in the
'skipit' array I ignore it, and if there are no matches then I assume it's a
required header and I output it. Again I'm working off of very little
knowlege about how all of this actually works so I'm sure there's got to be
a real solution to this. But for now at least the request works 100%
invisibly between these two servers and I am able to accomplish what I set
out to do.
Thanks for everybody's suggestions. Here is the modified function...

What fucntion should I use the move_uploaded_file() or copy() and what's the function's first argument so that the file is copied to the server? Thanks Hi, Your problem isn't your code, it's your method. The temp file is automatically deleted after confirmation.php dies. Therefore by the time you send the tmp_name through to the send_file.php it no longer exists. What you're going to have to do is copy() the tmp file to a permenant location within confirmation.php. And then post that information to send_file.php with an added subroutine to delete the file if the user goes back to change some info. Confirmations are normally only used durring descructive actions so you may consider ditching the confirmation screen all together.

Um not onload the link looks like this:
a onclick='openEdit(add=eventamp;cellid=10); return false;'
onkeypress='openEdit(add=eventamp;cellid=10); return
false;'href='edit.php?add=eventamp;cellid=10'Add an event/a
and the javascript looks like this:

function openEdit(params) {
var url = editsmall.php?+params;
var ewin = window.open(url, ewin,
width=500,height=300,toolbar=0,resizable=1,scrollbars=1);
ewin.focus();
}
Blows that theory away. :-)
I still believe what's happening is the edit script is being executed before
the parent script has died. Are you doing some kind of looping background
process or something that's keeping the parent script from exiting?
As far as I know you cannot have two instances of the same session running
simultaneously. The way I understand sessions it should be systemically
impossible to do so unless there's some kind of flock'ing option for session
files that I don't know of. Of course that doesn't mean PHP won't let you
try.
You need to avoid this situation by - killing that parent script- before
the edit script is launched. You can ensure this with output buffering as I
suggested before. Becuase you're controlling the output there won't be a
button to press until the parent script has died.
ob_start();
//script here//

Re: [PHP] Passing values back to form

Then you can header() redirect normally with no fuss and extract the values from the session file on the form page. And here's a tip. Set up some CSS in a switch() statement to highlight the form fields that are left blank. This makes for a nice user interface, esspecially on larger forms.

Once they have logged in (authentication via sessions, drawing from info held in a mysql database) they can then go wherever they want. What I am trying to get is that when they click on a link and login, the process then forwards them on to the page whose link they clicked on, rather than presenting them back with the home page. Basically, every page calls a function that checks whether the person is logged in, and if not redirects them to the login page. The login page register the $http_referer as a variable on the form - and when the form is submitted (ie. login takes place) that variable is passed on, and used for a location: instruction on success. The real kicker is that this worked fine when I developed it - using IE5 on my Mac (and still does). Only after a short while did I discover and realise that it wasn't working at all on IE5.5 / 6 on Windows. But surely these are server side operations, and if it works for one it should work for others? The only thing I can think of is that IE5.5 on Windows doesn't pass on the referer info in the same way?? In which case, is there an alternative way of capturing this that would withstand the differences? Thanks - Mallen print_r($_SERVER) to see what values are available to you.

print p.$myrow[vanNumber];
print br.$myrow[origin]. to .$myrow[destination];

Hi,
mysql_fetch_array(); produces two arrays, one indexed and one associative,
thus count() will return twice the expected number. Use mysql_fetch_row()
to retrieve a single indexed array or mysql_fetch_assoc() to retrieve a
single associative array.
Refer to the documentation:

Currently I am doing: $pinfo = fopen (/director1/directory2/filename.ini,r); Does this filename.ini contain the code to connect to your database? If so, I usually do two things with this file: 1. put it outside the document root, so users can't browse to it 2. put any code that might output something (an error message, for example) inside a function, so even if it is run, nothing will happen - you need to include() it and then call the function yourself. If it's just connection information, with no code (I'm a bit confused by the .ini extension :-) then just make sure it's somewhere outside your document root. Is XML a solution? I don't think XML is inherently any more secure than plain text - it's all down to how you store and transmit the data.

Re: [PHP] mysql_num_rows
Uh. no that can't be right becuase mysql_query() returns a pointer not an
array. The variable does contain a string refering to the pointer ID but
that's about all the information you're going to disseminate from print_r();

Subject: [PHP] mailing forms and input into MySQL
Hi all,
I have a current php script that allows me to add/remove customer
information from a particular MySQL Database. What I would like to do, is
when an employee adds a customer, have some (if not all) of that information
e-mailed to a particular e-mail address.
I've created scripts that e-mail info, and ones that just enter info into
a database, but have not attempted combining them.
Anyone have any ideas, or is anyone doing this? If so, could you give me
a quick how-to or point me in the direction of some online documentation?
Thanks,

Subject: [PHP] Date Problem - Last Day Of Month
Hi there, can anyone tell me how to fix my code so that on the last day of
the month, my code doesn't repeat the months...
What the code suppose to do is, makes a drop down box from which you can
select the month, and if its the current month
the box is already selected.
select name=month
?
for ($i=1; $i=12; $i++) {
if ($i == date(m)) {
print option selected value=\. $i . \ .
date(F,mktime(0,0,0,$i,date(d),date(Y))) . /option;
} else {
print option value=\. $i . \ .
date(F,mktime(0,0,0,$i,date(d),date(Y))) . /option;
}
}
?
/select
Thanks
Vinesh
Vinesh, there's a fundemental flaw in your logic. The date(d) input will
fail to produce a reliable list if it is executed on any day after the 28th
of the month. Since today is the 31st obviously this is going to cause some
problems becuase any month that ends on the 30th or earlier will return plus
one the month. So February will return March, April willl return May, and
so on. If you wait until tommorrow (the 1st) your function will magically
work. :)
One way to fix this is to build your own array of month names and reference
that instead of using the date() function.
$months = array(1=January, 2=February, 3=March, 4=April,
5=May, 6= ... and so on...);
for($i=1; $i=12; $i++)
{
$selected = ;
if ($i == date(m));{$selected = SELECTED;}
echo option $selected value=\${months[$i]}\\n;
}

Subject: [PHP] Files uploads problem
I am a learner in PHP - I have been using Larry Ullman's Peachpit
beginners
book which I have found useful to take me through the basics.
But the examples were written before the general applicaton of the new
$_POST, $_GET and similar arrays. It has been valuable learning to change
the code for that (I use version 4.2. (and a bit) and Larry Ullman is
very
helpful on his own website forum with readers' queries on the book
examples.
But I am having real trouble making a file upload programme work. It needs
substitution of $FileName given in the example with $_FILES array values
which I have done and use of isset instead of a raw if(). But I still
cannot get it to work
May I put the code here and ask if anyone can tell me the problme.
Incidentally I use Windows ME with Apache 2.0.36 and PHP 4.2.. The files
upload is on with a max size of 2M and no specific directory given for a
temp store (the INI says it will use the default directory.)
My test out script is as follows::-
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN
html
head
titleUploader/title
/head
body
?php
if(isset($_FILES['File'])) {
$File=$_FILES['File'];
$File_name=$_FILES['File']['name'];
$File_size=$_FILES['File']['size'];
echo (p$File_name/pbr /\n);
echo ($_FILES['File']['name']);
print(File name: $File_namep /\n);
print(File size: $File_sizep /\n);
if (copy ($_FILES[File][tmp_name],users/$File_name)) {
print(The file was sucessfully uploaded.p /\n);
}else{
print(Your file could not be copied unfortunately.p /\n);
}
unlink($File);
}
echo (Upload a file to the server.);
echo (Form action=\FileUpload.php\ method=POST
enctype=\multipart/form-data\\n);
echo (File: input type=file name=\File\br /\n);
echo (input type=submit name=\submit\ value=\Press here to
upload.\br // form\n);
//test whether anything prints for the FILES array
echo (pemfont color=\green\Can I get it to print the variable
outside the conditional? i.e. this one
{$_FILES['File']['name']}./font/em/p\n);
//set any old variable and print it to be sure basics work
$TestPrint=pbigfont color=\purple\Print this out
then./font/big/p.\n;
echo($TestPrint);
?
/body
/html
Is there something I've missed in the script. Or perhaps Apache 2 is the
problem?
Thanks
Couple of HTML problems to point out. Where you have br // form\n, /
form is an invalid tag. Remove the space. Also where you have
enctype=\multipart/form-data\ you need quotes after the slashes (ie. \)
otherwise PHP is going to assume that you want the litteral slash in the
HTML.
Niether of these errors will return visable error code but both will result
in you not being able to submit the form.
Also when you go to unlink($File); you're going to see an error becuase
$File is not a valid file path, it's an array. Besides you shouldn't worry
about trying to clean up the temp file. PHP will do it automatically when
the script exists. :-)

Re: [PHP] Re: Include Question
Guys I would say looping include()'s is just a bad idea all together. It
can get you into some gritty situations. For example it would be very easy
to end in an infinte loop, or overwrite variables, or just confuse the heck

include() at the end of the script. Just my opinion.

back to the root directory (although I would rather have them in a login
directory). Anyway, I have a question regarding the include function. I
have
a login script in a file called login.php - in this file it includes
checklogin.php and loginerrors.php. If the user inputs an incorrect
login
I
assign $messages the appropriate error from loginerrors, then I
re-include
login.php where I want to show the error message, but no matter what I
do
the error message will not show up.
Example.
Login.php
Enter your Name:
Enter Your Password:
if ($message) { echo $message; }
Checklogin.php
if (!$name || !password) {
$message = $enter_info;
include (login.php);
exit;
}

Here is the link to the site: http://tillergroup.com/test/ This person has a book, and therefore produces the problem (on Netscape 4.7): http://tillergroup.com/test/speaker_full.php?speaker_id=29 This person does not have a book, and the page loads fine without refreshing: http://tillergroup.com/test/speaker_full.php?speaker_id=60 The page is huge, so I hate to send the code for the whole page unless someone wants to see it. I am desperate for help! Thanks!! Amanda Well I can tell you that you're commenting out the lower half of the page source with this.. !--NETSCAPE--!. The correct syntax for HTML comments is !-- code --. I can also tell you that your first table is invalid. Apparently it doesn't have a closing tag but that's as much as my validator will tell me. Perhaps these problems are associated with the missing info? - Kevin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Subject: [PHP] php and javascript
Hi,
I'm not sure if this is a PHP or a JavaScript question but I have found
the
following code to enable me to select all of the checkboxes on my form.
SCRIPT LANGUAGE=JavaScript
!-- Begin
var checkflag = false;
function check(field) {
if (checkflag == false) {
for (i = 0; i field.length; i++) {
field[i].checked = true;}
checkflag = true;
return Uncheck all; }
else {
for (i = 0; i field.length; i++) {
field[i].checked = false; }
checkflag = false;
return Check all; }
}
// End --
/script
form name=mon_formulaire action= method=post
table
bWhere do you connect to the Internet from?/bbr
input type=checkbox name=list value=1Homebr
input type=checkbox name=list value=2Officebr
input type=checkbox name=list value=3Friends' homebr
input type=checkbox name=list value=4Post officebr
input type=checkbox name=list value=5Internet Cafébr
br
input type=button value=Check all
onClick=this.value=check(this.form.list)
/form
The problem is that in the example all of the boxes are called list and i
need to name each checkbox on my form with a different user_id so that i
can
collect the data sent from the form, is there a way around this?
Thanks in advance for any advice offered.
I see a number of possible solutions through PHP. The way that I would
handle this is to give each group its own numerical id. So something like..
Group #1
input type=checkbox name=list_1[] value=1Homebr
input type=checkbox name=list_1[] value=2Officebr
input type=checkbox name=list_1[] value=3Friends' homebr
Group #2
input type=checkbox name=list_2[] value=1Homebr
input type=checkbox name=list_2[] value=2Officebr
input type=checkbox name=list_2[] value=3Friends' homebr
Then in my script each group array can be accessed with something like this.
?
$num_groups = 2;
for($i=1; $i=$num_groups; $i++)
{
echo bGROUP #$i/bbr;
for($j=0; $jcount($_POST['list_'.$i]); $j++)
{
echo $_POST['list_'.$i][$j].br;
}
}
?
If you need to define each group with a userid then you cuold store those
ids in an array and use ereg() in a loop to parse the groups.
HTH,
Kevin

Re: [PHP] Sessions question
This is one of those rare things in programming that can only be done one way. Absolutely the only way to kill the session when a user leaves your site is to go through a script and then redirect after the session has been destroyed. For this to work every outgoing link on your website will have to point to a script. Then you'll pass the redirect url or url id (that referse to a url in your database) through the link and redirect after session_destroy() has killed the session. The link can look like this: a href=exit.php?url=http://www.thiersite.com;www.theirsite.com/a The script will look something like this: ? // exit.php session_start(); session_destroy(); header(Location: .$_POST['url']); ? Keep in mind if you want to do this then the user will not be able to use his/her back button in order to return to your website unless you define an additional redirect in a conditional that states if the session is not active then go here.

Re: [PHP] Session Not Working
Why is there a space between = = ? And where is $user_data and
$database_data coming form? First thing I would recommend you do is print
out those variables to make sure they actually contain the information
you're expecting.

Hello,
I'm trying to use sessions for the first time.
I have a log in script that gets the user to enter their name and
password. Then the script compares the entered data to a database.
If
the entered data matches whats in the database then the user is
granted
access to the main php script.
basically my code in the log in script is this:
if ($user_data = = $database_data) {
$_SESSION['verified_user']=1;
header(Location:http://www.myserver.com/main.php;);
exit;
The opening code in my main.php script is this:
session_start();
if ( isset($_SESSION['verified_user'])) {
run the whole script
}else {
return to log in page
exit;
}
Anyone care to clue me in as to why I'm always sent back to the log in
page even when the log in is correct?
Did I miss the session boat all together? Perhaps I'm not grasping it
at all..
Thanks,
Roger

Subject: [PHP] detecting end of line - php 4.1.2
Hi
I am trying to get php 4.1.2 to read a Mac file (exported from
FileMaker Pro) and split it into different lines using the following
but php does not recognize the end of line. For some tech reason I
cannot upgrade php now but I need to be able to read my Mac files
now. What is the easiest : edit the Mac file and replace the end of
line or modify the script below? In any case I need help to know
exactly what to do.
// first read the entire file
$file = file($Export_ImageBank);
// process each line in turn
foreach ($lines as $line_num = $line) {
// first split tab-separated fields
list($Image_ID,$Mark_Check,$Image_Good,$Image_VeryGood,$Image_ShortCodeOrgan
,$Image_Number,$Image_SubFolder,$Image_Format,$Image_MaxPxWidth,$Image_MaxPx
Height,$Image_Year,$Image_Month,$Image_Subject,$Image_CodeCountry,$Image_Reg
ion,$Image_Location,$Image_Collection,$Image_Caption,$Image_CodePrice)
= explode(\t, $line);
Please email me directly at [EMAIL PROTECTED] Thanks.

Kind regards, Paul.

I take it the file is ending up as one whole line in $file? Try the atomic
reaction method..
$file = explode(\r, implode(\r, file($_Esport_ImageBank)));
implode() ensures $file is a string, not an array and explode() breaks the
string on Mac end-of-line characters. With any luck that'll work for you.

Sincerely your;
pei_world ( .::IT::. )
There are some (what I would call) engineering issues with your function
but it looks like it should work. Maybe your problem lies in the array?
// Cleaned up function..
function array_is_numeric($array)
{
$result=true;
for($i=0; $isizeof($array); $i++)
{
if(!is_numeric($array[$i]))
$result=false;
}
return $result;
