Smart MySQL Escape Function
This function first checks to see if PHP is set to automagically quote stuff. If it is, we first strip pre-quoted stuff, then (assuming our text isn't numeric), we properly quote everything.
A good bit of room for improvement here, but at the very least, you should hit this before inserting anything into your database.
// check to see if a string needs to be escaped for database input
function escapeit ( $text ) {
if ( get_magic_quotes_gpc() ) {
$text = stripslashes($text);
}
if ( !is_numeric($text) ) {
$text = mysql_real_escape_string($text);
}
return $text;
}
