Hi,Good day!I created a search box and my problem is when I type Employee ID the auto list displayed is Employee Name, I need to display on the list is based on what I type. I don't know if it is possible that in one search box I can search Employee name then the list of names will display, when I type Employee ID, employee id list will display. same with Passport no and res id.Now, when I type Employee Id or Passport No or res id and employee name. the displayed list is employee name.this is my code:

<script type="text/javascript" src="js/jquery.js"></script>     <script type='text/javascript' src='js/jquery.autocomplete.js'></script>     <link rel="stylesheet" type="text/css" href="js/jquery.autocomplete.css" /><script type="text/javascript">//----auto complete emp no--//$().ready(function() {  $("#search_data").autocomplete("get_emp_info.php", {  width: 237,    minLength: 3,//search after three characters  matchContains: true,  mustMatch: true,  selectFirst: false  });     });</script>  <table>     <tr>     <td style="border: none;color:#80600a;font-weight:bold;">Search:</td>     <td><input type="text" name="search_data" id="search_data" value="" size="35" autofocus></td>     </tr>     </table>

<?phpob_start();include('includes/connection.php');$q = strtolower($_GET["q"]);if ($q == '') {  header("HTTP/1.0 404 Not Found", true, 404);}//else (!$q) return;else{$sql = "SELECT pe.employee_no, pe.employee_name, pe.passport_no,   gov.res_id   FROM tbl_personal_info AS pe JOIN tbl_public_info AS pu ON (pe.employee_no = pu.employee_no) JOIN tbl_e_government_info AS gov ON (pu.employee_no = gov.employee_no)   WHERE pe.employee_no LIKE '%".$q."%' OR pe.employee_name LIKE '%".$q."%' OR pe.passport_no LIKE '%".$q."%' OR gov.res_id LIKE '%".$q."%'";$result = $conn->query($sql);if ($result->num_rows > 0) {  // output data of each row  while($row = $result->fetch_assoc()) {     $pid = $row["employee_no"];     $employee_name = $row["employee_name"];     $passport_no = $row["passport_no"];     $res_id = $row["res_id"];           echo "$employee_name|$pid|$passport_no|$res_idn";   }} else {  echo "0 results";}$conn->close();  }?>
