我正在努力將cookie添加到我現有的登錄表單中。 這是我到目前爲止有：要記住上次登錄名的Cookie
的login.php
<?php require_once('../../Connections/connBoekengidsv2.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

$theValue = get_magic_quotes_gpc() ? stripslashes($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;

我讀過，你不能讀取同一頁上的cookie。它只能在下一頁（index.php）上完成。這是我編寫setcookie（）代碼行的地方。
的index.php
<?php setcookie('mijnLogin', $_POST['login'], time()+86400*30)?>
<?php
if (!isset($_SESSION)) {
session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";
// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
// For security, start by assuming the visitor is NOT authorized.
$isValid = False;
// When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
// Therefore, we know that a user is NOT logged in if that Session variable is blank.
if (!empty($UserName)) {
// Besides being logged in, you may restrict access to only certain users based on an ID established when they login.
// Parse the strings into arrays.
$arrUsers = Explode(",", $strUsers);
$arrGroups = Explode(",", $strGroups);
if (in_array($UserName, $arrUsers)) {
$isValid = true;
}
// Or, you may restrict access to only certain users based on their username.
if (in_array($UserGroup, $arrGroups)) {
$isValid = true;
}
if (($strUsers == "") && true) {
$isValid = true;
}
}
return $isValid;
}
$MM_restrictGoTo = "login.php";
if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {
$MM_qsChar = "?";
$MM_referrer = $_SERVER['PHP_SELF'];
if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
if (isset($_SERVER['QUERY_STRING']) && strlen($_SERVER['QUERY_STRING']) > 0)
$MM_referrer .= "?" . $_SERVER['QUERY_STRING'];
$MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" .urlencode($MM_referrer);
header("Location: ". $MM_restrictGoTo);
exit;
}
?>

所有這些代碼是屬性爲我添加了一個服務器行爲。我現在想要實現一個cookie，這樣第二次有人想要登錄時，用戶名已經填寫完畢。 我試過幾種嘗試添加它的方法，但都沒有工作。 當它測試它時，cookie不會被創建。如果我更改cookie的名稱以讀取現有的cookie，它確實有效。因此，某處登錄代碼會阻止創建cookie frome。
