Solution 1

PHP

$checkbox = isset($_REQUEST['checkbox']);
$countaa = count($checkbox);

You have set $checkbox to the boolean value returned by isset(), so count($checkbox) and $checkbox[$i] make no sense. You probably meant to set it to $_REQUEST['checkbox'].

Also, watch out for SQL injection - don't put $del_id in your query without escaping it first.
