[sabret00the]

thanks xenon, however still can't get it to work, could you please take a look at this and tell me i'm just coding this badly or not

PHP Code:

         $projectid = intval($_POST['projectid']);
         if (isset($rate_source)) {
             if ($rate_source == $PHP_SELF . '?projectid=' . $projectid) {
                 if ('project_rate' && $rate && $projectid != '' && $bbuserinfo[userid] > 0) {
                     $projectid = intval($_POST['projectid']);
                     $verify = $DB_site->query_first("
                         SELECT userid 
                         FROM project_rate 
                         WHERE projectid = $projectid AND userid = $bbuserinfo[userid]
                     ");
                     if ($verify) {
                         eval(print_standard_error('error_project_novotetwice')); 
                     } else {
                        $DB_site->query("INSERT INTO project_rate SET
                         projectid = '$projectid',
                         userid = '$bbuserinfo[userid]',
                         rate = '$rate',
                         timestamp = '".time ()."'");
             
                         header("Location: $PHP_SELF?s="); //takes you back to main project page
                     }
                 } else {
                     eval(print_standard_error('error_project_voteerror')); 
                 }
             } else {
                eval(print_standard_error('error_project_shouldnotbehere')); 
             }
         } else {
            eval(print_standard_error('error_project_shouldnotbehere'));
         }
