เอาฟังก์ชันนี้ไปใช้แทน header() ครับ
Code (PHP)
function Redirect($url){
echo '<script>';
echo "window.location.href = '$url';";
echo '</script>';
}
แทนบรรทัดนี้
Code (PHP)
header(sprintf("Location: %s", $updateGoTo));
ด้วย
Code (PHP)
Redirect($updateGoTo);
แบบนี้ครับ ไม่มีปัญหา

ข้างบนก็ละเอียดซะเป็นผงแล้วนะครับนั่น เอาแบบเต็ม
ขออธิบายก่อน
header("location: URL"); เป็นฟังก์ชั่นใช้สำหรับรีไดเรคไปหน้านึงๆ ที่เราต้องการ บางครั้งมันเกิดปัญหาดังที่คุณเห็นอยู่(มันแก้ได้ลองค้นดู)
แล้วนี่เป็นฟังก์ชันที่ผมใช้แก้ปัญหาดังกล่าววิธีนึง คือใช้จาวาสคริปให้มีประโยชน์
function Redirect($url){
echo '<script>';
echo "window.location.href = '$url';";
echo '</script>';
}
การเรียกใช้งาน ก็แค่
Redirect('ตามด้วย url ที่ต้องการให้ไป');
Code (PHP)
<?
ob_start();
function Redirect($url){
echo '<script>';
echo "window.location.href = '$url';";
echo '</script>';
}
?>
<meta http-equiv=Content-Type content="text/html; charset=utf-8">
<?php require_once('Connections/mk.php'); ?>
<?php
mysql_query("SET character_set_results=utf8");
mysql_query("SET character_set_client=utf8");
mysql_query("SET character_set_connection=utf8");
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
$editFormAction = $_SERVER['PHP_SELF'];

}
