Question

我正在使用会话制作登录表单但是。我有一个问题。

问题是。当我按下提交按钮时，我发送到＆＃34; login.php＆＃34;而不是＆＃34; office.php＆＃34;。还有＆＃34;错误＆＃34;变量是空的。所以我不知道问题是什么。

的index.php

<?php
include('login.php'); // Includes Login Script

if(isset($_SESSION['login_user'])){
header("location: office.php");
}
?>

<!DOCTYPE html>

        <form method="post" action="login.php">

    $rows = mysql_num_rows($query);
    if ($rows == 1) {
