Re: [PHP] Strange_session-problem_with_php-file_in_img_src
Problem solved. The error came because I was calling the function inside another function, outside the latter it worked good. So I simply passed the variable with the second function - works great! Thanks anyway for all your time trying to help me! /V -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

--- Victor [EMAIL PROTECTED] wrote: img src=createjpg.php?id=xyz ... The problem is that since the file createjpg.php is'nt loaded in the browser as and ordinary file, it doesnt recognizes the session variable. When a browser requests an image, the request is identical to a request for any other resource, be it a .html file or a .php script. It will send cookies, URL variables (if they are in the src attribute as your example shows), and anything else that a normal request includes. Instead of trying to tell us what the problem is, just explain what trouble you are having. We can then tell *you* what the problem is.

Ok, first I have the function
session_start();
function return_session_raettighet($session = null)
{
if ( isset($session) )
{
return $session;
}
else
{
return 0;
}
}
I ask this function to return the value of a specifik session, that is,
if the user is logged in the value is at least 10.
Then I perform
if(return_session_raettighet($HTTP_SESSION_VARS[session_raettighet])
10)
{
ImageAlphaBlending($img_des, true);
$im_copy = imagecreatefrompng(const_picture_dir . /copyright.png);
$copy_imgsize = GetImageSize(const_picture_dir . /copyright.png);
$copyxloc = (($imgwidth + (2*$kant))/2)-($copy_imgsize[0]/2);
$copyyloc = (($imgheight + (2*$kant))/2)-($copy_imgsize[1]/2);
imagecopy($img_des,
$im_copy,$copyxloc,$copyyloc,0,0,$copy_imgsize[0], $copy_imgsize[1]);
}
this means, that if the user is not logged in, a copyright © sign will
appear over the image.
And this fails
Don't know why because the same code works on other
pages
Sincerely
Victorr
