Question

这是代码

UsersController.php

<?php

class UsersController extends AppController
{
    public function login()
    {
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                return $this->redirect($this->Auth->redirect());
            }
            $this->Session->setFlash(__('Invalid username or password, try again'));
        }
    }

    public function logout()
    {
        return $this->redirect($this->Auth->logout());
    }
}

?>

User.php（模型文件）

<?php

class User extends AppModel
{

    public function beforeSave($options = array())
    {
        if (isset($this->data[$this->alias]['password'])) {
            $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
        }

        return true;
    }
}

login.ctp（查看文件）

<?php
echo $this->Session->flash('auth');
echo $this->Form->create('User');
echo $this->Form->input('username');
echo $this->Form->input('password', array('type' => 'password'));
echo $this->Form->end(__('Login'));
?>

的 AppController.php

<?php

class AppController extends Controller
{
    public $components = array(
        'DebugKit.Toolbar',
        'Session',
        'Auth' => array(
            'loginRedirect' => array(
                'controller' => 'books',
                'action' => 'view'
            ),
            'logoutRedirect' => array(
                'controller' => 'pages',
                'action' => 'home'
            ),
        )
    );
}

表名：用户

我是CakePHP的新手，我刚刚编写了简单登录操作的代码，
当我尝试使用正确的凭据登录时，它始终显示不正确的用户名和密码

$this->Auth->login()总是返回false值，即使我提供了正确的用户名和密码。请给我一个解决方案。谢谢。

你应该试试这个

在CakePHP数据库中，表名应为复数。模型名称应该是CamelCase的单数。控制器应为复数，并且必须添加CamelCase添加后缀 Controller 。查看文件夹名称始终与Controller复数名称（不带后缀）相同，.ctp文件名应为动词。

Answer 2

无意中我限制了数据库中的密码字段，以便密码部分存储在数据库中，这就是导致此问题的原因。
