[PHP] How to print nice looking text on an image?

[Kevin Stone]

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!

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 . "" . $errorcount .")
Email Address field does not contain @
\n";
  }
  else if (preg_match_all("/(.)/",
$_POST['Travel_Request_Email_Address'], $match) < 1)
  {
$errorcount++;
$error = $error . "" . $errorcount .")
Email Address field does not contain .
\n";
  }
  else
  {
$_SESSION['Travel_Request_Email_Address'] =
$_POST['Travel_Request_Email_Address'];
  }
}
else
{
  $errorcount++;
  $error = $error . "" . $errorcount .")
Email Address field is empty\n";
}

RE: [PHP] removing all duplicate values from an array

[Kevin Stone]

Or... you could use array_count_values() and loop through the array it
produces to find out how many of each duplicate value exists in the
original array.

Subject: [PHP] removing all duplicate values from an array

Hi,

I'm looking for a function that does almost the same as array_unique()

But it must also delete the other duplicate entry.

sample to explain:

array(
'a' => 'one',
'b' => 'one',
'c' => 'zero',
'd' => 'two'
);

I now want the result to be:

array(
'c' => 'zero',
'd' => 'two'
);

This way I will be able to do an array_diff and then see all the
duplicate 
entries listed.

this is to find dup. ip address for a hosting system, displaying both
accounts will make it easy to trace the amount of accounts 1 
ip curruntly has.


Anybody know how to do this?

Thanks,
Allowee

[PHP] Re: header() refresh vs location

[Kevin Stone]

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.

[PHP] Re: header() function for displaying an opened PDF document.

[Kevin Stone]

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.

Forget the content length and disposition headers.  Just set the content type then 
output the file..

header("Content-type: application/pdf");
readfile("junk.pdf");

"Pushpinder Singh Garcha" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]
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. !

Thanks in advance

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.

Chris,

This is just a thought.. I have never employed this method personally.. but I suppose 
you could read the page into a string and use the md5() function to generate a 
hexidecimal value based on that string.  Store the hex value in a database and compare 
it against the new value generated the next day.  If anything on the page has been 
modified the values should not match.  Even the most minute change should trigger a 
new value.  Obviously you won't know *what* has been modified only that the page *has* 
been modified

There are some pitfalls to keep in mind such as if the page contains dynamic content, 
if there is a server error, or if the page has been removed.  Thanks to Network 
Solutions evil Sitefinder you may find it difficult if not impossible to predict what 
will be read by your script if the page goes missing.  But this will all show up in 
the hex value and you won't know if the page is still relevant until you personally 
visit the links.

[PHP] Re: Central authentication for multiple sites

[Kevin Stone]

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.

This is less code and is tested.

$seconds = 86397; // any starting value
$days = floor($seconds/86400);
$days_mod = $seconds%86400;
$hours = floor($days_mod/3600);
$hours_mod = $days_mod%3600;

You cannot store file pointers.  If you output the variable it's going to
look something like "Resource ID #1" which is meaningless except to the
instance of the script that created it.  Or did you mean something different
by "$file pointer"?

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
 as the outputs.  Very little logic goes between the  tags
in my HTML files but of course sometimes it's unaviodable and that's why you
want to use  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.

Anyway.. just my two bits.  Take it or leave it.  :-)

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.");
}

The mail() function has two optional inputs.  Additional Headers and
Additional Parameters.  FROM and other optional headers can be set up like
this..

$headers = "From: [EMAIL PROTECTED]";
$headers .= "Cc: [EMAIL PROTECTED]";
$headers .= "Reply-To: [EMAIL PROTECTED]";

And then included as the fourth input to the function..

mail("[EMAIL PROTECTED]", "test", "testbody", $headers);

Be aware that forging headers can get you into trouble with the spam
blockers regardless of the legitimacy of your intentions.  Go to Google
Groups and read up on what you need to know in order to keep your legitimate
mail servers from being black listed.

Yup it's working perfectly.  $_GET['list'] overwrites $_GET['list']
overwrites $_GET['list'].  You will only ever see the last one.  Instead add
square brackets to each variable name..

http://awebsite.net/formlist.php?list[]=2&list[]=3&list[]=99

Now $_GET['list'] is an array wth three elements.

echo $_GET['list'][0]; // prints 2
echo $_GET['list'][1]; // prints 3
echo $_GET['list'][2]; // prints 99

To do this within your multi-select form field add the square brackets to
the field name...

date("Y-d-m",mktime(0,0,0,substr($firstdate,5,2),substr($firstdate,8,2),subs

Should do the trick, you can probably use strtotime instead of all
the substr()'s but at a guess I would expect the above to be quicker
(not that I have benchmarked it).

HTH

David's reply was spot on but I thought I'd break it down for you in case
you didn't understand...

$firstdate = "2003-06-28";

// Parse the date
list($year, $month, $day) = explode("-", $firstdate);

// Get the timestamp for this date..
$ts = mktime(0,0,0,$month,$day,$year);

// Add four days to timestamp..
$ts += 345600;

// Get year, month, day for new date..
$newdate = date("Y-m-d", $ts);

The only thing that I'm doing differntly is the way in which I'm parsing the
date.  I'm using the list()=explode() method as opposed to substr() becuase
this method is not prone to fail when values are not zero filled.

Good luck,

The resource identifier returned by mysql_connect() is an optional input to
the mysql_query() function.  You should test it out to see if your system
isn't passing the value automatically.

$result = mysql_query($sql, $connect); //<-- like this

The reason you may be seeing 1 instead of the value you expected is that the
mysql_query() function can return True even if it doesn't succesfully
execute the query.  In that case you may see the output 1 becuase the
boolean True evaluates to 1 in the parser.

I assume you want to KEEP the other values in the array?  If not then you
can just unset($myStuff).

If you do want to keep the array intact then I suppose you could store the
count in a variable $counta, add more elements to the array (or not), take
the count again and store it in a new variable $countb, then subtract the
values $count = abs($counta - $countb);

abs() converts to the absolute value if the result is negative.

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 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.



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 cannot emulate the javascript close command with PHP.  Output code from

Beauford, here's a login routine that I wrote using Sessions and Header
redirects.  It is my interpretation of what you are trying to do.  I'm not
saying this is the only way to do it but it works well for me.  Compare it
to what you're doing to see if you're doing anything wrong.

page-whatever.php
http://www.yourdomain.com".$_SERVER['REQUEST_URI'];
$_SESSION['return-to'] = $thispage;
if($_SESSION['valid_user'] !== true)
{
// Access Denied!  Redirect to the login screen.
header("Location: http://www.yourdomain.com/login.php";);
exit;
}

// Access Granted!  Display secure content.
?>

Hello World!
Click here to logout
-

login.php
 $val)
{
$_SESSION[$key] = '';
}

echo "You have logged out succesfully.";
// Continue to the login form..
}

// Validate form input if submitted..
if(isset($_POST['submit']))
{
if(valid_user($_POST['username'], $_POST['password']))
{
// Access Granted!  Redirect to the page that brought us here.
$_SESSION['valid_user'] = true;
header("Location: ". $_SESSION['return-to']);
exit;
}
else
{
echo "Invalid Username/Password.";
}
}

// Function to validate username/password..
function valid_user($un, $pw)
{
// Open database/userfile.
// Check submited input against content
// Return true or false based on result.
}

// Display the login form.

I would assume that if you turned register_globals off $PHP_SELF will no

You cannot do what you propose and there is no work around becuase PHP
automatically closes any connctions left open when the script closes,
rendering the resource/object handels invalid.

The compromise most people live with is to put their connection script
within a separate file and include it (either manually or automatically) at
the top of any script they may need to access the database in.  This at
least saves you the headache of maintaining twelve different instances of
the same code in a pile of scripts.

POST and GET are synonymous in PHP thanks to the $_REQUEST array.  If you
are not concerned about the input method then use $_REQUEST in place of
$_GET and $_POST.

When you redirect to login.php store the refering page in a hidden form
field field and redirect back to that url after the user has logged in
succesfully.

Look in the manual under 'printer'..

Printer functions are server-side and work on Windows operating systems

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

You make an interesting point however the problem is people reply to this
list using Email, Newsgroup and Web-based clients.  The clients don't all
put the same information in their headers and they don't all understand the
same headers.  If it were strictly a newsgroup list or strictly an email
list or strictly a web-based list then Yes you would have a valid point.
But if the list is to remain open to these different portals then you are
going to have to live with the occasional broken thread.

Case in point... => ME <=... I only recently moved from an Email client to a
Newsgroup client to view this list and I had no idea what-so-ever that any
of my replies were breaking threads.  It was a real eye opener.  :-)

You can try putting "LIMIT 1" on the end of your query but to be honest I
don't know if  LIMIT works with the DELETE command.  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.

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.

Re: [PHP] Re: Eval var from query

I realized that may not make any sense.  Following up the eample relates to
your original query like this..

> MySQL field `name` = hi my name is $name
> In my script I have:
> $name = "Shawn";

$data = 'hi my name is $name';
$code = 'echo "'.$data.'";';
$name = 'Shawn';
eval($code); // prints "hi may name is Shawn".

Hope that makes it more clear.

The string you send to eval() must be valid PHP code.  So try this..

Make a choice here..

=> session_register('foo');
=> $HTTP_SESSION_VARS['foo'] = 'bar';

Use either the session_register() function or the session global array.  Not
both.

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

[Kevin Stone]

I'd just dump all of the results into an array and do something like this:

echo "\n";
for($i=0; $i\n";
for($j=0; $j<2; $j++)
{
echo "\t\t".$array[$i]."\n";
$i++;
}
echo "\t\n";
}
echo "\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.

Re: [PHP] New to PHP

[Kevin Stone]

No there are no real pre-requisites to learning PHP.  You should be
comfortable working with the OS that you're used to, but that goes without
saying.  PHP is an almost ideal beginner's language.  Knowledge of Linux is
certainly not required.  There are PHP installers for Windows and Mac that
are point and click.  Very easy step by step.  And there's plenty of easily
accessible info on Google Groups if you get stuck.

Re: [PHP] New to PHP

[Kevin Stone]

There are many great books to help get you started.  Infact.. believe it or
not.. for the complete newbie "PHP for Dummies" is a great chioce.  It's
very well written and starts with no assumptions about your skill level.

But if you do happen to have some programming experience try "PHP and MySQL
Web Development" (do a search on Amazon).  That's the book that helped me
out the most.  It has some great real-world examples with complete
walk-through tutorials.

Don't bother purchasing a function reference becuase the php.net reference
is the best there is.  And it's free.  :)

HTH,
Kevin

Hi I am new to PHP and would like to learn more about it. Which would be the
best place to start with besides the manual and what would you suggest is a
pre-requiste for learning PHP.

Thanks

[PHP] Reg Ex to search for both Integer and Comma-spaced Integer

[Kevin Stone]

I'm a little confused by something.  I need to build a reg-ex to scrape for
both plain integers and comma spaced integers in the same place in the same
string at the same time.  For example..

$string = "Mark's average score was 544.";
preg_match("/average score was ([0-9]+)/", $string, $matches);
$score = $matches(1);

$string = "Julie's average score was 10,443.";
preg_match("/average score was ([0-9]+,[0-9]+)/", $string, $matches);
$score = $matches(1);

How do I combine these two queries so that the reg-ex matches both the comma
spaced integer and regular integer?

Thanks!

You're missing a starting bracket.

You know this was WAY too easy to find.  What kind of editor are you using
that would miss something this obvious?

On an unrelated note you can save yourself a lot of grief by separating your
logic and content.  In your case a page template with the look and feel of
the message page.

/** message_page.html  **/



 




/** index.php **/
if($login)
{
$message = "Please enter your Username or Sign Up.";
include("message_page.html");
}
else
{
$message = "Thank you for login in.";
include("message_page.html");
}

This is just a friendly suggestion.  I know most people don't like to be
preached to.  :)

[SNIP]

Mark, this is kind of a lame hack but give it a try...

/** PAGE A (first form) **/


/** PAGE B (second form) **/


/** PAGE C (results page) **/



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.

HTH,
Kevin

Logan,

When you're activating the script through the browser then
$_SERVER['QUERY_STRING'] is always set.  It is only empty or not empty.  You
should modify your conditional statements to reflect that..

http://www.helpelf.com/test2.php";);
}
?>

This is tested.

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...

# ===
# PostToHost($host, $path, $data_to_send)
# $host = valid domain (ie. http://www.asiostudio.com)
# $path = relative URL (ie. /myfile.php)
# $data_to_send = urlencoded key/val string (ie.
"key=val&key2=val2&key3=val3")
# ===
function PostToHost($host, $path, $data_to_send)
{
 $fp = fsockopen($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))
 {
  $str = fgets($fp, 128);

  $skpit = array(
  "HTTP/1.1 200 OK",
  "Date:",
  "Server:",
  "X-Powered-By:",
  "Connection:",
  "Content-Type:",
  "enSSL");

  $out = true;

Yes but when I fail to output the socket file the request is no longer
recieved.  No data is recorded in the POST array.  Let me explain once more
what I'm doing..

1) Initiate Script-A through the browser.
2) Script-A opens a socket connection to Script-B and posts a request.
3) Script-B produces a formated data string based on the requst.
4)  Script-B then opens a socket connection to Script-A and posts the data.

It should be seamless and it works for the most part.  But the thing is it
outputs this generic server info which you can see in this working example..

http://www.helpelf.com/test.php

You'll notice in the example that this server info.. I don't know what it is
becuase this is the first time I've done anything like this.. gets outputed
along with the request.  I can't NOT (double negative) output the request
file becuase it contains the headers and data which make it all work.  At
least that is what I realized a few minutes ago when I said ACK then Oh (see
two posts below).  :-)

Now I'm looking for a way to avoid that server info output, without
compromizing the functionality of the method,  if it is possible to do so.

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?

[PHP] How to avoid Socket Post output?

[Kevin Stone]

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)
 $data_to_send; urlencoded key/val string (ie.
"key=val&key2=val2&key3=val3")
*/
function PostToHost($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?


Thanks,
Kevin Stone

Oh you're right I didn't read the original post.  You can still use the OB
method and redirect to an HTML page containing the "sorry we're not here,
we're redirecting you to the right location" message and meta refresh
without goofing up the output in the original script.  It's a straight
forward and clean transition.

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.

HTH,
Kevin

Calling session_write_close() at the end of the script will do nothing of
consiquence if you launch the edit script before the function is called.
You end up with the same "page not found" error.

I just don't see how this could have solved your problem except to do the
same thing that output buffering would have done and that is to
(essentially) queue the execution of the two scripts.  Anyone care to
explain this?

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//
ob_end_flush();

Kevin

I'll bet you're using an onLoad command to launch the popup aren't you.  Use
Output Buffering to keep stdout from flushing before the parent script dies.
If my assumption about onLoad is correct then that'll solve your problem.

Re: [PHP] Passing values back to form

[Kevin Stone]

Hi Daniel,

My advice is to use php sessions.  You can register both the filled and
empty values in the session after processing them.  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.

Read up on sessions..

Subject: [PHP] Passing values back to form


Im new to PHP coming from a background in perl devlopement.  I have a form
that a user can fill out.

On submit the values are iterated over a foreach to check for empty().  If
the an emtyp $key is found then it passes an error string to my error
function.

I have 2 php files, one that is the Form called profile.php and one that
processes the values from the form, called profileprocess.php.  There are
multiple functions in profileprocess.php.  When the header function is
called in the profileprocess.php it takes you back to the profile.php with
empty values in the fields.  I was wandering if their is a way, (which Im
sure their is) to pass back all the data that was correctly entered back to
the form, and then a nice little message that displays the error of the data
that needs to be checked by the user.  I could do this a number of ways, but
the key is not writing code that you dont have to.  Its just smarter
programming.

Any ideas, or functions I could read on in the rtFM manual is greatly
appreciated.

I appreciate you looking at this problem...
Thanks in advance,
Daniel

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:
http://us2.php.net/manual/en/function.mysql-fetch-array.php

print_r($_SERVER) to see what values are available to you.

If HTTP_REFERER is blank, which is entirely possible, try HTTP_HOST and
SCRIPT_NAME and pass those to your from the intranet page to your login
script instead of getting the referrer after you've redirected to the login
script.

Uh. no that can't be right becuase  mysql_query() returns a pointer not an

You should be accessing the $_GET, $_POST and $_SESSION arrays directly
rather than relying on request vars to be parsed automatically.  This will
allow you to be much more discriminatory in your code.

I will add in this case that include() is going to be no less secure than
fopen(), plus it's going to be a whole hell of a lot easier.

Couple of HTML problems to point out.  Where you have "\n",  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.  :-)

Kevin

You might be able to be more precise using ereg_replace().  But I donot know
the regular expression to make it happen.  Or if your situation allows it
you can hack it by appending a single space on the end of each input.
Either way what you need to do is give the script more information about
exactly what you want to replace.

echo str_replace("Blue ", "Red ", $paragraph);

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 "\n";
}

Kevin

You can open a file, write to a variable, and then send that through a POST

Re: [PHP] Re: Include Question

[Kevin Stone]

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
out of the PHP parser.  I recommend you do a header() redirect rather than
include() at the end of the script.  Just my opinion.

You'll find examples at the bottom of the page of some code that you can add
to the script.  Or if you know where the input for the script is coming from
then you can use extract($_POST) or extract($_SERVER), or whatever, at the
top of the script.

with this line:
GetNextDate("4", "2003-03", "5");

that $frequency ends up ""? Whether I set it myself when I call the

with nothing in it. empty() returns 1, while isset() returns nothing on

Good question.  Are you certain your not misspelling "frequency" when you

\r\n should be used (esspecially in email!) to be compatible with all

The uploaded file's path is stored in $_FILES['photonew']['tmp_name'];  You

From, CC and BCC are headers to be set in the fourth parameter of the mail()
function.  Headers must be spearated by end-of-line characters.

$headers = "From: [EMAIL PROTECTED]
CC: [EMAIL PROTECTED]
BCC: [EMAIL PROTECTED]";

mail($to, $subject, $body, $headers);

There are many other headers that you may find useful that are just as easy
to add through the mail() function.

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.

Re: [PHP] Sessions question

[Kevin Stone]

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:
http://www.thiersite.com";>www.theirsite.com

The script will look something like this:


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".

Voodoo.  *LOL*

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
Home
Office
Friends' home

Group #2
Home
Office
Friends' home

Then in my script each group array can be accessed with something like this.

GROUP #$i";
 for($j=0; $j";
 }
}
?>

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

Well I can tell you that you're commenting out the lower half of the page
source with this..  .  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?

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; $ihttp://www.php.net/)
