CAPTCHA newpost & reply - UBB.Developers

Hej
This post will describe how to install a captcha in newpost and replies, so its possible to allow anonymous posters, without open your forum for spambots. The capatcha will thus only have effect for anonumous posters. Registrated users can ignore captcha.

Its provided that you have uploaded:
audit.php
button.php

If you havent, you can download them here. You can read about the captcha and test it here http://php.webmaster-kit.com/

Modified files
addpost.php
addpost.php(language file)
newpost.php
newpost.php (language file)
newreply.php
newreply.php (language file)
newpost.tmpl
newreply.tmpl
addpost_prewiev.tmpl

Step 1.
open addpost.php(language file) and add the lines

Code


$ubbt_lang['NO_CAPTCHA'] = "Wrong digits";
$ubbt_lang['ENTER_DIGITS'] = "Enter digits if you're not logged in";

Step 2.
Open newpost.php( language file) and add the line

Code


$ubbt_lang['ENTER_DIGITS']  = "Enter digits if you're not logged in";

Step.3
Open newrely.php(language file) and add the line

Code


$ubbt_lang['ENTER_DIGITS']  = "Enter digits if you're not logged in";

Step.4
Open newpost.tmpl and newreply.tmpl and add the captcha and digit input box

Code



<br/>
<img width="120" height="30" src="button.php" border="1" />




<b>
{$ubbt_lang['ENTER_DIGITS']}
</b>


<input type="text" maxlenght="5" size="5" name="userdigit" class="formboxes" value="" />

Step.5
NOTE!In addpost_prewiev.tmpl, the captcha has to be put into 2 places, because you have 2 options. One option to send the post, and a option to edit the post. You may not exclude one of them, otherwise it will not work!

Code

</form>

</table>
UBBTPRINT;
/* UBBTREMARK */ ?>

Step.6
Open addpost.php and add the code just before these lines
// -----------------------------------------------------
// Now if we are doing a preview of the post, we do this

Code


//------------------------------------------------------------	
// Captcha - af Arentzen
	if( ($config['anonnames']) && (!$Username) ) {
	include "audit.php";
	if(audit()){
	}
	else {
		$html -> not_right($ubbt_lang['NO_CAPTCHA'],$Cat);
	}
	}

Step.7
Open newpost.php and newreply.php and put in a "dummy code" in the middle of the scripts, so you dont get error message when executing the scripts.

Code


//---------------------------------------------------------------------------
// Reset captcha ved besvarelse - af Arentzen	
	if( ($config['anonnames']) && (!$Username) ){
	include "audit.php";
	if(!audit()){
	}
	}

Then we are finish. You should now be able to open your forum for anonymous without collecting spamposts from spambots...
