Question

我已经为我的代码创建了一个if语句用于登录，并且我试图让按钮使用if语句，这样如果用户详细信息被授权，那么他们就可以访问该页面。

我遇到的问题是，我想获取提交按钮以验证用户是否已获得授权并将其重定向到另一个页面，但是如果登录详细信息不正确，则无法登录

这是我的代码：

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
   if ((isset($_POST['email']))  && (isset($_POST['password'])) ) {
        if (isAuthenticate($_POST['email'], $_POST['password']))
         header("Location: roster3101.php");
         exit();
   }
}

header("Location: index.php");

?>

Answer 1

isAuthenticate是一个javascript函数。你不能将它用作php函数。你需要编写一个处理auth东西的php函数。

如果声明为用户授权
