Thank you

<?php require_once('../Connections/connection.php'); ?>

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {

I think the error is update statement,so i cannot update the value to the database

$editFormAction = $_SERVER;if (isset($_SERVER)) { $editFormAction .= "?" . htmlentities($_SERVER);} if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) { $updateSQL = sprintf("UPDATE student_info SET student_e=%s, present_time=%s WHERE id=%s", GetSQLValueString($_POST, "text"), GetSQLValueString($_POST, "int"), GetSQLValueString($_POST, "int")); mysql_select_db($database_connection, $connection); $Result1 = mysql_query($updateSQL, $connection) or die(mysql_error());}
