for those who style have some problem, edit theme.inc.php


add :


Quote
'{CONFIRM}' => $lang_display_comments['confirm'],


after

Quote
'{COMMENT}' => $lang_display_comments['comment'],




then add

Quote
<tr>
  <td class="tableb_compact" colspan="2">
    {CONFIRM}
  </td>
  <td class="tableb_compact" colspan="2">
    <input type="text" name="confirmCode" size="5" class="textinput"> <img src="captcha.php" align="middle">
  </td>
</tr>


after (style of your website depending Wink)

Quote
<!-- END input_box_no_smilies -->

In my gallery, the confirmation image does not show up anymore. I don't know what happened to it. Example:

@gymnastdude182: Was the image beign shown previously? If yes, then it means that your webhost changed something in php setup and freetype2 is no longer supported on your server.

He told me he did not edit any of that   Sad what happened? Is it because I input a 404 error page? I removed that and it still does not work. That's the only thing I can think of that I edited.

Well, it finally happened to me. I started getting porn spam on my youths sports gallery - http://www.bullseyephotos.com/sports/index.php. Good thing that I have email notification set up for everything that happens on that site otherwise some young person or parent might have seen it and I would have been clobbered. I was able to install this mod in 5 minutes following Abbas' instructions in the initial post in my gallery which is heavily modded without any issues. Excellent work and many thanks Abbas!  Grin

Cheers,

@mvyvoda: Did you modified captcha.php file? When http://www.derpishi.com/gallery/captcha.php is opened, it should show an image. But in your case the page comes blank. Also do you have error messages turned off on your server?

here's the error message i now see on http://www.derpishi.com/gallery/captcha.php:
Quote
Fatal error: Call to undefined function imageftbbox() in /home/vyvodamr/public_html/gallery/include/captcha.class.php on line 115

my ISP doesn't know what's up with this. could it be something with the captcha.class.php code? any suggestions are more than welcome and I appreciate the time and energy of your help!!! currently, i've turned off commenting for unregistered users. please advise if you need me to turn it back on.

thanks a lot!,

Well, well... I find this mod very interesting and useful, but I was not able to do the modifications and get this thing to work. I'm very illiterate regarding code. I will have to find another solution to avoid those freaking spammers.

But thank you Abbas Ali, anyway.

Wonderful hack! Just a minor comment, if you're using another language than english it might be a good idea to use:

Code:
require("include/captcha.class.php");
        if (!PhpCaptcha::Validate($_POST['confirmCode'])) {
          cpg_die(ERROR, $lang_errors['captcha_error'], __FILE__, __LINE__);
        }

instead of

   
Code:
require("include/captcha.class.php");
        if (!PhpCaptcha::Validate($_POST['confirmCode'])) {
          cpg_die(ERROR, "Confirmation code didn't matched", __FILE__, __LINE__);
        }

in db_input.php

I made a small modification so users who are logged in don't need to confirm, while anonymous users has to.
I haven't tested how secure this is, but it seems to work. My modification for theme.php is written for the Project VII-theme, you have to adjust it for your own theme. The trick is to write two versions of $template_add_your_comment, one for users who are logged in and one for those who aren't.

I just write the modifications necessary after you have done Abbas Alis modifications.

In db_input.php:

Instead of
Code:
require("include/captcha.class.php");
        if (!PhpCaptcha::Validate($_POST['confirmCode'])) {
          cpg_die(ERROR, "Confirmation code didn't matched", __FILE__, __LINE__);
        }

write

Code:
if (!USER_ID) {require("include/captcha.class.php");
        if (!PhpCaptcha::Validate($_POST['confirmCode'])) {
          cpg_die(ERROR, $lang_errors['captcha_error'], __FILE__, __LINE__);
        } }

In theme.php, instead of

Code:
$template_add_your_comment = <<<EOT
        <form method="post" name="post" action="db_input.php">
                <table align="center" width="{WIDTH}" cellspacing="1" cellpadding="0" class="maintable">

This seems like a bit unnecessary complicated, but I couldn't get it working in any other way.

Check phpinfo, look for the GD section, see if freetype is actually there. Should look similar to http://coppermine-gallery.net/demo/cpg14x/docs/faq.htm#VersionGD

freetype is now installed and i can see the captcha image!!!!!! thanks for all the help. I am still having a problem however. It seems as though the confirmation image doesn't work properly because I can comment w/o typing the captcha image.

did i do something in correct w/ modding the code?

thanks for the help. i do appreciate it!

Did you not edit db_input.php? That's the part that tests for whether the confirmation code is correct.

Niiiice.

Just edited the files to make it work.
Didn't have freetype2 in my webhotel but after contacting my provider they gave me a newer server with more phun stuff to play around.

Thank you for the mod Abbas Smiley

(offcourse, I had to get the first pr0n spam comments to my gallery to get this done (g*ay links to a BMW picture Wink )

Sorry for such a basic question but I'm new to all this PHP stuff. I;ve just taken over a website that is being bombarded with spam. Am going to try this out but falling down at the 1st hurdle - where can I find my 'Coppermine Root Directory?'

I've searched in all the folders of the website but can't find it! Again, sorry for the basic question but is it really obvious where it is?

Sorry everyone - I've just found it all. But I think I will have to upgrade the gallery I have as I think it is a bit out of date - some of the code mentioned doesn't exist in my coding.

However, is it right that when I download the file it only has 4 files and nothing about fonts that was mentioned in the original post?
