Anti-Spam Addon Modification for Frontend

[peppy]

Hi,

i´m sorry for my english and i hope you understand me.

In the last days i had many spammers that used my comment-formular for commercial comments.

It is easy to kill this comments with the addon Pixelpost Anti-Spam (anti_spam.php - version 2.0). But after some days i hade no fun to kill this comments manual. So i changes the index.php. With this modification the script compares the comment with the spamlist of the Anti-Spam-Addon before the comment will be saved. If there ist more than one word in the spamlist, the script exits.

To use the modification you must use the Pixelpost Anti-Spam-Addon (anti_spam.php - version 2.0)

Than you must insert following code in the index.php

PHP Code:

            // do not insert comments with spam
                $level_of_spamprotection = 1;  //how many words of your spamlist should be in a comment before it is spam
                $message_temp = explode(" ",$message );
                $spam_i = 1;
                
                // Get the ban list
                $query = "SELECT banlist FROM {$pixelpost_db_prefix}ban LIMIT 1";
                $result = mysql_query($query) or die( mysql_error() );
                if( $row = mysql_fetch_row($result) ) {
                    $banlist = $row[0];
                    $banlistarray = explode( "\n", $banlist );
                } else {
                    $banlist = '';
                    $banlistarray = array();
                }
                
                $spam_array = $banlistarray;
        
                foreach($message_temp as $ti) {
                        if (in_array($ti, $spam_array)) {$spam_i ++;}
                } 
                if ($spam_i > $level_of_spamprotection ) {die ("Your comment contained words which are filtered by my spam list");}
            // do not insert comments with spam 


Thera are two places where this code must be insertet. First one is bevore this line

PHP Code:

        sql_save("
    insert into ".$pixelpost_db_prefix."comments(id,parent_id,datetime,ip,message,name,url,email)
               VALUES('NULL','$parent_id','$datetime','$ip','$message','$name','$url','$email')
                    "); 


Second one is before this line

PHP Code:

if($parent_id == "")    $extra_message = "<b>$lang_message_missing_image</b><p />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"; 


Tested with version 1.4.2 of Pixelpost.
