PHP致命错误：未捕获错误：在控制器的负载模型中找不到类

Question

我有这个MVC文件夹结构：

application
-----------catalog
------------------controller
----------------------------ProfileContoller.php
------------------model
----------------------------UserModel.php
------------------view
------------------language
-----------admin
------------------controller
------------------model
------------------view
------------------language
core
---- Controller.php
public
vendor
....

现在，在ProfileController.php中，我有：

namespace Application\Catalog\Controller;

use Application\Core\Controller as Controller;

use Application\Core\Model\UserModel;

class ProfileController extends Controller
{
    /**
     * Construct this object by extending the basic Controller class
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * This method controls what happens when you move to /overview/index in your app.
     * Shows a list of all users.
     */
    public function index()
    {
        $this->View->render('profile/index','', array(
            'users' => UserModel::getPublicProfilesOfAllUsers())
        );
    }

}

在usermodel.php中，我有：

namespace Application\Catalog\Model;

class UserModel
{

    public static function getPublicProfilesOfAllUsers()
    {
        $database = DatabaseFactory::getFactory()->getConnection();

        $sql = "SELECT user_id, user_name, user_email, user_active, user_has_avatar, user_deleted FROM users";
        $query = $database->prepare($sql);
        $query->execute();

        $all_users_profiles = array();

        foreach ($query->fetchAll() as $user) {

            array_walk_recursive($user, 'Filter::XSSFilter');

            $all_users_profiles[$user->user_id] = new stdClass();
            $all_users_profiles[$user->user_id]->user_id = $user->user_id;
            $all_users_profiles[$user->user_id]->user_name = $user->user_name;
            $all_users_profiles[$user->user_id]->user_email = $user->user_email;
            $all_users_profiles[$user->user_id]->user_active = $user->user_active;
            $all_users_profiles[$user->user_id]->user_deleted = $user->user_deleted;
            $all_users_profiles[$user->user_id]->user_avatar_link = (Config::get('USE_GRAVATAR') ? AvatarModel::getGravatarLinkByEmail($user->user_email) : AvatarModel::getPublicAvatarFilePathOfUser($user->user_has_avatar, $user->user_id));
        }

        return $all_users_profiles;
    }

并使用Composer Psr4 I自动加载文件：

"autoload": {
        "psr-4": { "Application\\": "application/","Application\\Core\\": "application/core/","Application\\Catalog\\Model\\": "application/catalog/model/"}
    }
    }

现在,当我需要路由我的URL时,我会采取行动：

$route->get('/cms/profile/index/', 'Application\Catalog\Controller\ProfileController@index');

我看到这个错误：

Answer 1

在这里，您调用的函数的类名为model class在控制器中不存在。UserModel::GetPublicProfileSofAllUsers()

使用Application\Controller\Model\UserModel作为

或

use Application\Controller\Model\UserModel;

class ProfileController extends Controller
{

    protected $userModel;
    /**
     * Construct this object by extending the basic Controller class
     */
    public function __construct()
    {
        parent::__construct();
        $this->load->model('UserModel');
    }

您可以调用为

$this->View->render('profile/index','', array(
            'users' => $this->UserModel->getPublicProfilesOfAllUsers())
        );

最好的方法是通过对象调用非静态函数。在PHP5.3中，我们可以将非静态函数作为静态函数，但在PHP7+中，它被标记为不推荐使用，并将在未来删除它。
