'.$row_last_name.'</a></td>                     </tr>                      <tr>                       <td><div align="right">birth date:</div></td>                       <td>'.$row_birthdate.'</td>                     </tr>                     <tr>                      <td><div align="right">registered:</div></td>                      <td>'.$row_registered_date.'</td>                     </tr>                      <tr>                      <td><div align="right">governorate</div></td>                      <td>'.$row_gov.'</td>                     </tr>                     </table>                     <hr />             ';             }        }     } } else {     $errormsg = "no member has listed location!!"; }  ?>

html code

  <table width="94%" height="63">                 <tr>                   <td width="29%"><form id="form1" method="post" action="member_search2.php">                    <h3>search location</h3><br />                   <?php require_once('location_fields.php'); ?>                     <input type="hidden" name="listbyq" value="by_gov" />                     <input type="hidden" name="listbyq" value="by_dist" />                     <input type="hidden" name="listbyq" value="by_city" />                     <input type="submit" name="searchbylocation" id="button" value="go" />                   </form></td> </tr> </table>

this because assigning same name input field name="listbyq", change name different among them can retrieve in different variables

<input type="hidden" name="listbyq" value="by_gov" /> <input type="hidden" name="listbyqa" value="by_dist" /> <input type="hidden" name="listbyqb" value="by_city" />

now can use them respectively in if statements

 if($_post['listbyq'] == 'by_gov')  if($_post['listbyqa'] == 'by_dist')  if($_post['listbyqb'] == 'by_city')

then remember mysql_ functions deprecated advise switch mysqli or pdo , indeed @ risk of sql injection, have here how can prevent sql injection in php?. should use prepared statment avoid risk
