Question

我创建了两个php文件..一个包含所有功能，另一个包含用户名＆amp;密码..但是当我输入正确的用户名时，我收到错误。密码。尽管我在表单中输入了正确的密码，但它告诉我错误的组合。请验证我的代码：

文件login.php

include 'init.php';

if(empty($_POST) === false){
    $username = $_POST['username'];
    $password = $_POST['password'];

    if(empty($username) === true || empty($password) === true){
        $errors[] = 'You need to enter a username and password';
    } else if(user_exists($username) === false){
        $errors[] = 'We cannot find that username. Have you registered yet?';
    } else if(user_active($username) === false){
        $errors[] = 'You have not activated your account yet';
    } else{
        $login = login($username, $password);
        if($login === false){
            $errors[] = 'That username or password combination is incorrect';
        } else{
            echo 'Okay';
        }
    }

    print_r($errors);
}

Users.php

function user_id_from_username($username){
    $username = sanitize($username);
    return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function login($username, $password){
    $user_id = user_id_from_username($username);

    $username = sanitize($username);
    $password = md5($password);

    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND 'password' = '$password'"), 0) == 1) ? $user_id : false;
}

init.php文件

<?php

session_start();
//error_reporting(0);

require 'database/connect.php';
require 'functions/general.php'; // general contains the senatanize function
require 'functions/users.php';

$errors = array();


?>

PHP和MySQL无法检索密码
