I have a trouble with my code below :

<form name="form" method="get" action="" autocomplete="off">

                                    {

                                }
                            ?>

This code are not error but not yet useful. because when I try to find (example : find by date : "27-Apr-2012") the data show, but it show with double data whereas in database that's not a double data.

I suspect the code in here maybe :

$sql = "select t_submissions.submission_no,
                                    t_submissions.badge_id,
                                    t_submissions.employee_name,
                                    t_submissions.ot_date,
                                    t_submissions.ot_from,
                                    t_submissions.ot_to,
                                    t_submissions.submission_by,
                                    t_acknowledged.status_acknowledge,
                                    t_submissions.status_approve

                                    from t_submissions, t_acknowledged where t_submissions.employee_name like '%$q%' or ot_date like '%$q%' or t_submissions.badge_id like '%$q%' and t_submissions.submission_no=t_acknowledged.submission_no ORDER BY time_submission DESC";

how to combine 2 condition if it has "or" & "and" ?

Thank you for helping.
