Question

我有以下课程用户：

class USER
{
    private $db;
    //constructor que estable la conexión con la base de datos
    function __construct($DB_con) {
        $this->db = $DB_con;
    }

    //Estable el login del usuario
    public function login($uname, $upass)
    {
        try 
        {
            $query = $this->db->prepare("SELECT * FROM users WHERE user_name=:uname");
            $query->execute(array(':uname'=>$uname, ':upass'=>$upass));
            var_dump($query);

当我创建var_dump（$ query）;

时，我得不到任何结果

我的index.php如下

require_once 'inc/config.php';

//Si el usuario esta logueado

if($user->is_loggedin())
{
    $user->redirect('home.php');
}

if(isset($_POST['btn-login']))
{
    var_dump('dentro');
    $uname = $_POST['txt_uname'];
    $upassword = $_POST['txt_password'];
    if($user->login($uname,$upassword))
    {
        $user->redirect('home.php');
    }
    else
    {
        $error = "Nombre de usuario y/o contraseña incorrecto";
    }
}

有什么问题？我在phpmyadmin中尝试查询，然后得到结果。

我做错了什么？

你想要获取它 public function login($uname, $upass) { try { $query = $this->db->prepare("SELECT * FROM users WHERE user_name=:uname"); $query->execute(array(':uname'=>$uname, ':upass'=>$upass)); var_dump($query->fetch(PDO::FETCH_ASSOC));

PHP - 我没有得到任何结果选择查询
