我正在创建一个PHP和MySQL登录页面。我已经注册工作但是当我到达登录页面时，我收到HTTP 500错误。我很确定它是login.php文件，因为注册工作正在使用相同的connect.php文件。

的login.php

<?php  //Start the Session
session_start();
require('../inc/connect.php');
if (isset($_POST['username']) and isset($_POST['password'])){
    $username = $_POST['username'];
    $password = $_POST['password'];
    $query = "SELECT * FROM `user` WHERE username='$username' and password='$password'";

    $result = mysqli_query($connection, $query) or die(mysqli_error($connection));
    $count = mysqli_num_rows($result);
    if ($count == 1){
        $_SESSION['username'] = $username;
    }else{
        $fmsg = "Invalid Login Credentials.";
    }
}
if (isset($_SESSION['username'])){
    $username = $_SESSION['username'];
    echo "Hai " . $username . "";
    echo "This is the Members Area";
    echo "<a href='logout.php'>Logout</a>";

}else{
    echo  "Please login.";
}
?>

<?php
$connection = mysqli_connect('localhost', 'username', 'password');
if (!$connection){
    die("Database Connection Failed" . mysqli_error($connection));
}
$select_db = mysqli_select_db($connection, 'beta');
if (!$select_db){
    die("Database Selection Failed" . mysqli_error($connection));
}
?>

答案 0 :(得分：0)

它没有工作的原因是它说＆＃34; ../ inc / connect.php＆＃34;它从另一个目录而不是web根目录中提取。所以我将其更改为＆＃34; ./ inc / connect.php＆＃34;有效。
