Also, just a caution, you will need to take some care in figuring when and where to place your 'and' statements linking the various parts of the query.

So do something like:
$query = "SELECT id, name , lastname , m_date from users where 1 "; if (isset($_POST['name'])) { $query .= "AND name like binary '%{$-POST['name']}%' "; } if (isset($_POST['lastname'])) { $query .= "AND name like binary '%{$_post['lastname']}%' "; } //etc etc $query .= " order by id ASC "; $sql = mysql_query($query) or die(mysql_error());
