Improved Spam list plugin

[kirby145]

This is a very small improvement but definately a time saver. Now on the spam word blocker plugin when you add or remove a word, you don't have to go through another page to continue. This just keeps it all on one page and makes a little message telling you if it worked.

Simply paste this in /plugins/spam.php

Code: Select all

<?php
/*
Plugin Name: Spam filter
Plugin URI: http://cutenews.ru
Description: Create a list with words and don't allow comments which contain these words.
Version: 0.1
Application: CuteNews
Author: Лёха zloy и красивый
Author URI: http://lexa.cutenews.ru
*/


add_filter('news-allow-addcomment', 'spam_filter');

add_filter('cutenews-options', 'spam_AddToOptions');
add_action('plugin-options', 'spam_CheckAdminOptions');

function spam_filter($allow){
global $name, $mail, $comments;

$barword = new PluginSettings('BarWord');

if ($comments){
foreach($barword->settings as $bad){
if (preg_match("/$bad/i", strtolower($comments))){$allow = false;}
}
}

return ($allow ? true : false);

I'm not a php expert but I was able to figure this little trick out

And, in case you want to add in a few spam words from the start, here's a list of common comment spam words:

But does it actually improve the current spam plugin? Or is this just a timesaver to add and remove spam words?
I think the current spam plugin is not "Spam Proof" at all. I use at several websites, a guestbook by a comment page and after a couple of weeks, the spam bots find their way to my guestbook and ahve to setup a standalone guestbook.
So if this is really an improved spam plugin...
Please tell us.

[kirby145]

Nope just a timesaver sorry. I'm sure next version will improve some of its spam blocking though.

[D72]

that's a shame. I used your code anyway and waiting patiently for a improved spam blocker
i hate spam!

how can i add an error message ? like "Sorry we dont accept this word :p"

heheheh
