[SOLVED] Session var works in FF but not in IE

Yesideez · July 13, 2007

In the include at the start of the code session_start() is beign called.

Part of the script:

  if ($_POST['submit']) {
    echo 'C='.$_SESSION['vercode'].'<br />V='.md5($_POST['vcode']);
    if (md5($_POST['vcode'])==$_SESSION['vercode']) {

My captcha script:

<?php
  /* makeimg.php
  **
  ** Created: 11-Jun-2007 (Zeb)
  ** Edited : 11-Jun-2007 (Zeb)
  *****************************************************************************/
  session_start();
  $imgWidth=130;
  $imgHeight=34;
  $chars='abcdefghijkmnqrstuvwxyz0123456789ABCDEFGHIJKLMNPQRSTUVWXYZ';
  $strText='';
  for ($i=1;$i<7;$i++) {$strText.=substr($chars,mt_rand(0,strlen($chars)-1),1);}
  $_SESSION['vercode']=md5($strText);
  header("Content-type: image/png");
  $img=imagecreatetruecolor($imgWidth,$imgHeight); //22
  $colBG=imagecolorallocate($img,0x11,0x11,0x11);
  $colFG=imagecolorallocate($img,255,255,255);
  for ($i=0;$i<strlen($strText);$i++) {
    $colFG=imagecolorallocate($img,mt_rand(100,255),mt_rand(100,255),mt_rand(100,255));
    imagettftext($img,20,mt_rand(-40,40),10+($i*20),27,$colFG,'fonts/times.ttf',substr($strText,$i,1));
  }
  imagepng($img);
  imagedestroy($img);
?>

In the captcha script I've tried removing session_start() in case that makes a difference and it doesn't. I've also got two other sites hosted on exactly the same web space using the same code and they both work - this one doesn't.

I just can't get the session variable to read - this is a sample of what I get in the browser:

C=
V=3588b8a8010f88846007457cf3cb87fd

Anyone see what I'm doing wrong here?

btw, this is the page in action:

captcha script looks ok..

try another file

ie

test.php

<?php
session_start();
print_r($_SESSION);
die();
?>

Yesideez · July 13, 2007

Now why didn't I think of debugging using that?

MadTechie · July 13, 2007

because you would hate to find a simple solution due the amount time spent LOL

happens to me all the time.. ::)

Yesideez · July 13, 2007

heh how true!

Here's what I used for testing:

<?php
  session_start;
  echo 'SESSION:<pre>',print_r($_SESSION),'</pre>';
  echo 'SESSIONcheese:<pre>',print_r($_SESSION['cheese']),'</pre>';
  $_SESSION['cheese']=md5('bleh');
  echo 'SESSIONcheese<pre>',print_r($_SESSION['cheese']),'</pre>';
?>

The result can be seen here: http://braeside.pictureinthesky.net/test.php

Yesideez · July 13, 2007

The full script itself is here: http://braeside.pictureinthesky.net/contactus.php

EDIT: Just remember I disabled the captcha until I can get this sorted as they need emails sent - soz for posting that link!

MadTechie · July 13, 2007

well its setting the session, can you post more of the form code please

have you tried

<?php
start_session(); //Added
  include("db_connect.php");
  include("fn_encodestr.php");
  include("fn_secureint.php");
//.....

Yesideez · July 13, 2007

That didn't work - the session_start() is in the db_connect.php file also as well as in the makeimg.php file.

http://braeside.pictureinthesky.net/contactus.php

I've enabled the captcha routine.

C: The session variable (always empty!)

V: What the user enters

Yesideez · July 13, 2007

FIXED!!!

Don't know why but I've not had to make this change on the other sites that use exactly the same captcha script.

All I did was move the following line AFTER header():

$_SESSION['vercode']=md5($strText);

Some reason the header setting the file to PNG was losing all of the session variables.

[SOLVED] Session var works in FF but not in IE
