如何在php中登录后将用户重定向到特定的链接 [英] how to redirect user to particular link after login in php

问题描述

我想知道如何在用户点击添加到购物车按钮并且如果该用户没有登录后在用户登录后将用户重定向到特定链接，例如在电子商务网站中的用户名
，那么用户将被重定向到登录页面，登录后用户将被重定向到请求页面
的购物车页面，所以我想知道如何为此编码。

{
        $url=' .php';//here i want dynamic link which is requested page link when user tries to access

推荐答案

首先检查用户是登录还是而不是

First check user is login or not

if(isset($_SESSION['username'])){
$url='cart.php';
}else{
$url='login.php';
}
<a href="<?php echo $url; ?>">add to cart</a>
