变量没有在数组中传回

此问题与this主题相关。我将语法更改为建议的语法,因此我的代码现在看起来像这样:

课堂上的方法:

private $password;
private $user_id;
private $img_thumb;

public function getUserInfo(){
            $stmt = $this->dbh->prepare("SELECT user_id FROM oopforum_users WHERE username = ?");
            $stmt->bindParam(1, $this->post_data['username']);
            $stmt->execute();

            while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {

                $password = $row['password'];
                $user_id = $row['user_id'];
                $img_thumb = $row['thumbnail'];
            }
            return array(
                'password' => $this->password,
                'id' => $this->user_id,
                'thumb' => $this->img_thumb
                );

        }

致电计划:

session_start();
require_once('init.php');

$username = trim($_POST['username']);
// create a new object
$login = new Auth($_POST, $dbh);

    if($login->validateLogin()){

        $_SESSION['loggedin'] = true;
        $list = $login->getUserInfo();


        $_SESSION['password'] = $list['password'];
        $_SESSION['id'] = $list['id'];
        $_SESSION['thumb'] = $list['img_thumb'];
}

没有任何变量似乎被传递回调用程序,我是否遗漏了类中需要明确声明可以传回的内容?

print_r()'$list数组,它不包含三个变量。

数据库中确实存在三个条目。

在调用程序中将检索到的数据库条目返回到数组中我做错了什么?

1 个答案:

答案 0 :(得分:2)

在while循环中,将变量分配给当前对象:

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
  $this->password  = $row['password'];
  $this->user_id   = $row['user_id'];
  $this->img_thumb = $row['thumbnail'];
}

更新:您错过了SQL中的一些字段:

SELECT user_id, password, img_thumb FROM oopforum_users WHERE username = ?
