如果用戶未登錄，則 PHP 重定向 - Yii2

Question

如果 CO 最終確定，我的站點會向用戶發送帶有鏈接的電子郵件。

如果用戶未登錄，則用戶必須首先轉到登錄頁面，並且只有當用戶登錄時，他們才會被重定向到 url。

現在，如果用戶已登錄，他們會直接轉到 url，但未登錄會轉到登錄頁面，他可以登錄，但不能直接訪問 url 任何人都可以幫忙嗎？

這個帶有一些參數的頁面 url 作為鏈接發送給用戶

應該使用會話來處理登錄。

假設您的網址是http://somedomain.com/somepage.php?token=some_tokan 。 因此，在somepage.php ，使用會話檢查進行登錄確認，例如：

<?php 

   ob_start();
   session_start();  

   if(isset($_SESSION['ssid']) &&  $_SESSION['ssid'] == session_id() ) 
   { 
          // do your stuff, after login confirm
   }          
   else { 
        // redirect to loginPage.php
        // With "header('Location:yoururl'); for example
   }

在loginPage.php 中，成功登錄憑據后，分配$_SESSION['ssid']值，如：

    ob_start();
    session_start();  
    //  if login credentials are verified.
    $_SESSION['ssid'] = session_id();
