I had written a captcha generator a few weeks ago and hadn't had a chance to see how to implement it in phpBB3. I downloaded yours to save myself some time searching through the code for how.

Anyway, your install steps lead me to a way to integrate my own captcha generator with a single line of code. I thought you might be interested.

I put my image generating code into a class called "captcha" and created a new method called "execute" which takes two parameters, $code and $seed. You then put the code to generate the image in the execute method, set the headers, and output the image. For example

Code: Select all

<?php
class captcha
{
  function execute($code, $seed)
  {
    $image = generateCaptcha($code);   

    header('Content-type: image/png');
    header('Cache-Control: no-cache, no-store');
    header("Expires: Thu, 01 Jan 1970 00:00:00 GMT");
    imagepng($image);
    imagedestroy($image);
  }

  /* The rest of my code that actually creates the image...*/
}
?>

execute() doesn't need to use $seed, but it needs to accept it if you want to reuse the code already in phpBB.

The in "includes/ucp/ucp_confirm.php", find "include($phpbb_root_path . 'includes/captcha/captcha_gd.' . $phpEx);" and replace with the include path for your captcha class.

The phpbb3 core code already does that, in effect. see includes/captcha/*.*

I'm instead working on a different solution, the class I created for the next version does not affect the native captcha but adds itself to the ACP options for it, like an alternate solution the user can choice from.

Thank you.

After I install the MOD and try to register, after I agree to the terms I get a JPEG image with the URL of registration page! I think that the reason is in these headers in ucp_register.php...

Would you mind to post a screenshot of the issue?

Hi,

First, thanks for the mod.

I've installed this and it seems to basically be working fine. My one comment is that the explanation as provided in common.php:

Code: Select all

Enter the code exactly as it appears. All letters are case "sensitive", there are (no zero, no o, no O).

Is apparently incorrect. As far as I've been able to tell, all letters are actually case insensitive. I've confirmed this on my site with the mod installed, as well as on your demo-site at http://gold.io3di.com/ucp.php?mode=register

Unless I''m doing something drastically wrong, I am able to successfully register using any mixture of upper and lower case that I choose, as long as I get the letters presented in the CAPTCHA correct.

I don't know if your preference is to fix the code to make it truly case-sensitive or to change the description to say that it is case insensitive. I've done the latter on my board for now.

Thanks again.

[3Di]

Thanks for feedback. I'll test it out myself and fix it of course. I do prefer to have it case SenSiTiVe.

I see, hmm. Please post here: http://gold.io3di.com/pastebin.php your includes/ucp/ucp_register.php file as PHP highlight, thank you.

Do you have GD library enabled in your php.ini? Have a look with the phpinfo facility provided by your phpBB3 ACP, thanks.
