在某些瀏覽器中未定義cookie的索引

Question

我使用的是登錄腳本，我在專家的幫助下發現在用戶登錄時創建cookie。

登錄頁面的過程是這樣的：

function process_login() { 

    var username = $.trim($('#input_username').val()); 
    var password = $.trim($('#input_password').val()); 

    username = $.trim(username); 
    password = $.trim(password); 
    var remember = document.getElementById("remember_user_checkbox").checked; 

    if (!username || !password) { 

     return false; 

    } 

    remember == true ? remember = "true" : remember = "false"; 

    $.ajax({ 
     type: "POST", 
     cache: false, 
     url: "login_user.php", 
     data: "username=" + username + "&password=" + password + "&remember=" + remember, 
     dataType: "json", 
     success: function (data) { 

      if (data == "FALSE") { 

       $('#input_password').val(""); 

       alert("The username or password you have entered is incorrect."); 

       return false; 
      } 

      window.location = "orders-home.php?<?=time()?>"; 

     } 

    }); 

} 

並提交login-user.php，在這裏：

<?php 
include('login-config.php'); 
$username = pg_escape_string($_POST['username']); 
$password = pg_escape_string($_POST['password']); 

//no encryption for now 


//php gets this as a string 
$remember = $_POST['remember']; 

if ($remember == "true") 
{ 
    $remember = TRUE; 
} 
else 
{ 
    $remember = FALSE; 
} 


$user_query = "SELECT * FROM users WHERE username = '$username' AND password = '$password' LIMIT 1"; 

$user_result = pg_query($con , $user_query); 

if (!$user_result) 
{ 
    echo json_encode("FALSE"); 
} 


$arr = array(); 

if (!$user_result) 
{ 
die(pg_last_error($con)); 
} 
else 
{ 

     while ($row = pg_fetch_array($user_result)) 
     { 

      //put the customer id in a session so we can put it in a cookie later 
      //then when the page is refreshed the stored customer id will be used 
      //as their ksisoldby identifier 
      if ($row['cust_id']) 
      { 
      $_SESSION['customer_id'] = $row['cust_id']; 
      $_SESSION['customer_name'] = $row['first_name']." ".$row['last_name']; 
      $_SESSION['uid'] = $row['id']; 


      if ($remember) 
      { 
       remember_user($row["id"]); 
      } 
      } 

     $arr[] = array(

     "first_name"   =>$row['first_name'], 
     "last_name"   =>$row['last_name'], 
     "customer_id"   =>$row['cust_id'], 
     "accepted_terms"  =>$row['accepted_terms'], 
     ); 
     } 

} 

if (empty($arr)){ 
echo json_encode('FALSE'); 
} 
else 
{ 

    $path = '/webtrack'; 
    $site = 'www.isco.net'; 


    if ($remember === TRUE) 
    { 
     $remember_time = time()+60*60*24*30; 

     setcookie('username', $username, $remember_time, $path, $site); 
     setcookie('customer_id', $_SESSION['customer_id'], $remember_time, $path, $site); 
     setcookie('customer_name', $_SESSION['customer_name'], $remember_time, $path, $site); 
     // setcookie('uuk', $uuk, $remember_time, $path, $site); 

    } 
    else 
    { 
     setcookie('username', $username, false, $path, $site); 
     setcookie('customer_id', $_SESSION['customer_id'], false, $path, $site); 
     setcookie('customer_name', $_SESSION['customer_name'], false, $path, $site); 

    } 

echo json_encode($arr); 

} 
?> 

我再從該cookie打印在主屏幕

<div class="fl customer_id"> 
    <?= strtoupper($_COOKIE['customer_name']); ?> 
</div> 

但我得到錯誤

Notice: Undefined index: customer_name in /home/iscotest/public_html/webtrack/orders-home.php

實際網站是www.isco.net。但該網站託管在iscotest.com。 isco.net只是指向iscotest.com。這可能是爲什麼我的cookie沒有被設置？

這是一個相當的問題，因爲這完全杜絕頁的負荷，作爲cookie信息來檢索顯示

另一個奇怪的是，這個錯誤沒有出現一致的數據。我在一臺電腦上看到safari和chrome上的錯誤，但該網站通常在safari和chrome中的另一臺電腦上運行。

感謝所有幫助

當您使用setcookie（）函數來創建一個cookie，這將只提供另一頁上。因此，它可能是您的AJAX問題。
