how able remove specific 1 form , post sql statement delete?

<? if (isset($_post['submit'])) {   echo "hello!";   $selectoption = $_post['info'];    $query = "select * `requests` order $selectoption";    echo $query;   $result = $db->query($query);   if ($result == false) {          die ("could not execute statement $query<br />");   }      else   echo "<form action='' method='post'>";   echo "<table>";        while($row=$result->fetchrow()){     if ($row['status'] == 0) {       $type="rejected";   }   else if ($row['status'] == 1){       $type="pending";   }   else if ($row['status'] == 2){       $type="accepted";   }     echo "<tr id=".$type."><td>" . $row['requestid'] . "</td>";   echo "<td>" . $row['booking_type'] . "</td>";   echo "<td>" . $row['userid'] . "</td>";   echo "<td>" . $row['moduleid'] . "</td>";   echo "<td>" . $row['no_rooms'] . "</td>";   echo "<td>" . $row['park'] . "</td>";   echo "<td>" . $row['semester'] . "</td>";   echo "<td>" . $row['day'] . "</td>";   echo "<td>" . $row['start_time'] . "</td>";   echo "<td>" . $row['end_time'] . "</td>";   echo "<td>" . $row['length'] . "</td>";   echo "<td>" . $row['students'] . "</td>";   echo "<td>" . $row['priority'] . "</td>";   echo "<td>" . $row['comments'] . "</td>";   echo "<td>" . $row['status'] . "</td>";     // <td class="'.(($row['status'] == 2) ? 'status-rejected' : 'status-accepted'). '">'.$row['status'].'</td>';   echo "<td>".$stats."</td>";*/   echo "<td>" . $row['round'] . "</td>";   echo "<td>" . $row['date_submitted'] . "</td>";   }    echo "</tr>";    echo "</table>";    echo "</form>"; }   echo "</tr>";   echo "</table>";

i don't understand trying delete.

if want delete data / row in database, need use delete statement explained here: http://www.w3schools.com/sql/sql_delete.asp

i guess statement this:

delete requests requestid=$row['requestid'];

$row['requestid'] actual unique key identifier data row delete.

edit: create button / link exact page data (yourpage.php?deleteid=1) pass id of data delete database.

keep in mind using paratemers isn't best way this. should rather use form , post regarding id.
