标签： php mongodb

我正在尝试为登录页面添加用户，但即使代码中没有提供重定向，它也会保持重定向

的login.php 

<?php
include './connect.php';
session_start();
if (($_SERVER["REQUEST_METHOD"] == "POST") && (!empty($_POST['username'])) && (!empty($_POST['password']))) {
    $postedUsername = $_POST['username'];
    $postedPassword = $_POST['password'];
    $userDatabaseFind = $database->login->findOne(array('username' => $postedUsername, 'password' => $postedPassword));
    $storedUsername = $userDatabaseFind['username'];
    $storedPassword = $userDatabaseFind['password'];

    if (($postedUsername == $storedUsername) && ($postedPassword == $storedPassword)) {
        $_SESSION['username'] = $storedUsername;


        if($_SESSION['username'] == 'admin'){

            session_regenerate_id();
             header('location:printDetail.php');
            }
        else{
                session_regenerate_id();
                header('location:welcome.php');
        }

    } else {
        echo 'Error';
    }
}

printDetail.php 

<?php
require './connect.php';
require './login.php';

//SEARCHING ACROSS THE COLLECTIONS IN THE DATABASE

$printDetailCollections = $database->details;
$printDetailCursor = $printDetailCollections->find();

//INITIALIZE THE VALUE TO ZERO SO IT CAN GO THROUGH THE DATABASE

$i = 0;

//USERNAME AND PASSWORD ARE CHECKED IF IT IS ASSIGNRD THEN THE SESSION IS DISPLAYED

if (isset($_SESSION['username']) && !(empty($_SESSION['username']))) {

    //LOOP FOR TRAVERSING ACROSS THE DATABASE

    foreach ($printDetailCursor as $doc) {
        $i++;
    }
} else {
    header('location:index.html');
}
?>

我在mongodb登录和详细信息中有3个集合。添加用户尝试访问登录集合以添加用户

addUser.php

我试图通过URL禁用对printDetail.php的访问 我认为这是重定向的主要原因。但是无法找出代码中的错误

只需点击用户名

字段即可重定向网页

P.s：我知道以这种方式存储的密码是不安全的

1 个答案:

答案 0 :(得分：0)

我在我的服务器上尝试了您的代码，并在尝试以addUser.php形式输入内容时确认了页面重定向问题...

你的错误在于以下几点：

<nav class="navbar navbar-inverse">
    <ul class="nav navbar-nav navbar-left">
        <li><a href="printDetail.php"><span class="glyphicon glyphicon-arrow-left">Back</span></li>
    </ul>
</nav>

你没有为＃34;关闭＆＃34;关闭ancor。

结果是你的所有形式和页面的每个元素（直到另一个ancor ......但没有）被浏览器包含在这个ancor中。
然后也是＆＃34;返回＆＃ 34;链接。 enter image description here 这很简单。

使用[F12]通过控制台和代码检查器进行调试，下次...
