problem with captcha field 2007/05/31 13:40	Karma: 0
Hi, i have a problem with the captcha field.. I tested the field locally and it works, but when i tried it in my website the image doesn't appear... Maybe it's fault of the website server ? how can i fix this?

Hello

Make sure your server has gd libraries enabled. you can check this by using this small script.

Code:


 
<?php
header("Content-type: image/png");
$im = @imagecreate(110, 20)
    or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 119, 255, 111);
imagestring($im, 1, 5, 5,  "GD Found", $text_color);
imagepng($im);
imagedestroy($im);
?>

Seeing the server setting seems that GD libraries are enabled, but the problem remain... Here is a link to the form.. http://lnx.salsamarchestyle.com/index.php?option=com_forme&fid=1 (the captcha field is named "codice antispam")

I tried the script but i receive an internal server error...

My Gd configuration:

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

If you see my guestbook here captcha works...

I too have a problem with captcha. My server is Linux Gentoo with gd installed. I must admit to not completely understanding how to implement this field using the supplied fields. Perhaps I just have something wrong in the field. Help! Bob Rynkiewicz

seems like captcha on some servers does not work because of session issues. I will fix it next week.
