"</td>"; echo "<td>" . $row['Reg_L_Name'] . "</td>"; echo "<td>" . $row['Reg_Request'] . "</td>"; echo "<td><input name=\"checkbox[]\" type=\"checkbox\" id=\"checkbox[]\" value=\"".$rows['Reg_ID']. "\" /></td>"; echo "</tr>"; } echo "</table>"; echo "<form action='' method='post'> <input type='submit' name='use_button' value='Update' /> </form>"; if(isset($_POST['use_button'])) { echo "Updated"; $update_id = $_POST['checkbox']; foreach($update_id as $value){ $sql = "Update Request set Reg_Status=0 WHERE Reg_ID='".$value."'"; $result = mysql_query($sql); } } mysqli_close($con); ?> the database is not updated when i click update.
