PHP會話變量在刷新時顯示爲空

爲了讓我的網址更加美觀，並使多步驟激活過程更加簡單，我編寫了我的頁面，將激活電子郵件中的用戶ID和激活碼存儲爲會話變量。當一個userID和actCode在url中時，它將它們保存爲會話變量，然後重定向到激活（我使用htaccess來取消.php部分）PHP會話變量在刷新時顯示爲空

它在第一次（當頁面刷新時），但是當您移動到不同的步驟或手動刷新頁面時，它會將其擦除。

這裏是我的代碼：

<?php 
error_reporting (E_ALL^E_NOTICE); 
session_start(); 

if ((!empty($_GET['u'])) && (!empty($_GET['a']))) { 
    $_SESSION["activate_userID"]  = $_GET['u']; 
    $_SESSION["activate_actCode"]  = $_GET['a']; 
    header('Location:activate') ; 
}else{ 
    $userID = $_SESSION["activate_userID"]; 
    $actCode = $_SESSION["activate_actCode"]; 
    echo 'session variable found: '.$actCode; 
} 

if ($actCode == ""){$actCode = "nUlL";} 


require "***connection script***"; 



$checkCode = "SELECT ***account details***, `activationExpire` FROM `users` WHERE `userID` = \"$userID\"; "; 
$result = $conn->query($checkCode); 

if ($result->num_rows > 0) { 
    // output data of each row 
    while($actInfo = $result->fetch_assoc()) { 
    *** account details are here *** 
    $step    = $actInfo['activationStatus']; 
    $activationCode  = $actInfo['activationCode']; 
    $activationExpire = $actInfo['activationExpire']; 
    } 
} 
?>

就我所見，您的代碼似乎是正確的，並且會話cookie被髮送到服務器。你可以看看服務器上的php/tmp目錄並打開其中一個會話文件（它們具有會話ID作爲名稱）並查看它們是否包含值？編輯：也嘗試print_r（$ _ COOKIE），看看是否有會話cookie – x4rf41

我得到陣列（[PHPSESSID] => 170f07f1467f149eda07f3 *******） –

@ x4rf41我應該這樣做，而不是一個會話的cookie變量？ –
