I understand you … I use the bbcode and this is my security function

public function post($post,$type=false) {

if(get_magic_quotes_gpc()){

$post = stripslashes($post);

}

$post = mysql_real_escape_string($post);

$post = trim($post);

$post = ($type==false?strip_tags($post):htmlspecialchars($post));

return $post;

}

in comment box i’m doing

post($_POST,true);

and on each other i’m doing

post($_POST);

this is true ?
