CakePHP - 在非对象错误时调用成员函数allow()

Question

我正在 CakePHP 中创建一个登录身份验证应用程序，并收到此致命错误：在第 5 行的 /var/www/cakephp1/app/Controller/users_controller.php 中的非对象上调用成员函数allow()

这是我的控制器代码 users_controller.php

<?php
class UsersController extends AppController {
    public function beforeFilter() {
        parent::beforeFilter();
        $this->Auth->allow('add');
    }
    public function add() {
        if (!empty($this->data)) {
            $this->User->create();
            if ($this->User->save($this->data)) {
                $this->Session->setFlash('User created!');
                $this->redirect(array('action'=>'login'));
            } else {
                $this->Session->setFlash('Please correct the errors');
            }
        }
        $this->set('groups', $this->User->Group->find('list'));
    }
    public function login() {
    }
    public function logout() {
        $this->redirect($this->Auth->logout());
    }
    public function dashboard() {
        $groupName = $this->User->Group->field('name', 
            array('Group.id'=>$this->Auth->user('group_id'))
        );
        $this->redirect(array('action'=>strtolower($groupName)));
    }
    public function user() {
    }
    public function administrator() {
    }
    public function manager() {
    }
}
?>

应用程序控制器.php

<?php
class AppController extends Controller {
    public $components = array(
        'Acl',
        'Auth' => array(
            'authorize' => 'actions',
            'loginRedirect' => array(
                'admin' => false,
                'controller' => 'users',
                'action' => 'dashboard'
            )
        ),
        'Session'
    );
}
?>

查看登录.ctp

<?php
echo $this->Form->create(array('action'=>'login'));
echo $this->Form->inputs(array(
    'legend' => 'Login',
    'username',
    'password',
    'remember' => array('type' => 'checkbox', 'label' => 'Remember me')
));
echo $this->Form->end('Login');
?>

我正在使用 CakePHP 版本 1.3

Answer 1

1.解决方案：您需要做的就是在UsersController中添加以下行：

public $components = array('Auth');

或者

2.解决方案：在UsersController中：

App::uses('AppController', 'Controller');

class UsersController extends AppController {

}

然后在AppController中：

public $components = array('Auth');
