I appreciate the information, too. I was about to undertake the project for myself, but this was much quicker!

Awesome job!

The Captcha hack works fine in the secon page of registration form. I want avoid the second page and tried to bring the captcha to fist page(Because most users ignore/forget to press finish button in secong page and complaint for incomplete registration).

For this i edited include/registerform.php, but returns parse error.
Can you help.
Thanks

This may need another thread, but I'll ask it here to start -

I have uploaded the same version of Frameworks and the same modified /class/xoopsformloader.php and /register.php to 2 different servers. On one I get the images, on the other I get text. Any idea why?

Same version of XOOPS on both servers. On my local XAMPP server (3rd site to test) I get the images.

@ skenow
Please check your Frameworks/Captcha/Config.php
Line 15
$config = array(
"mode" => 'text',

You can use 'text' or 'image' values and it works correct with me.

May be you have different values for mode.

Hope this will help.

Do have any ideas on removing the second page in registration and bringing captcha to the first page?

If it was only that easy - all sites are the same: 'image'. I'm wondering if it has to do with the check in img.php to see if GD extension is loaded. All sites report the same - it's loaded and 2.0.28 compatible.

Starting at line 127
switch ( $op ) {
case 
'newuser':
...
    include 
'footer.php';
    break;
case 
'finish':
is how the process is divided in 2 steps. I would probably look at using Formulize and it's registration codes to customize your process instead of hacking the core register.php.

I've done a bit more research and I have discovered why one of my sites does not use the image mode for verification. There are several required functions for the image mode to work correctly and if they are not present, the code sets the mode to 'text'.

GD2 and Freetype2 support are required for the images.

Now I just need to get my host to add Freetype2 or move me to another server.

Does anyone know if the 1.10 Frameworks captcha can be used with XOOPS 2.2.4 user registration? We'd like to do away with the user activation as an increasing number of registrations are not being verified, but I'd like to drop in a captcha to keep spambots/automated registrations at bay.


Thanks!
