CakePHP 3 : 即使数据不是从数据库中获取的，也返回 true - CakePHP 3 : returns true even if data is not fetched from database

CakePHP 3 : returns true even if data is not fetched from database

我在CakePHP 3.2中工作。有一个表user_addresses我正在尝试从中获取用户的所有记录

public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}

为了检查它，我在控制器的beforeFilter中添加了myFun

$this->Auth->allow(['myFun']);

这将打印 World 而不是 Hello，因为没有从数据库中检索到的数据，因为如果用户未登录，那么$user_id必须为空。

首先检查$user_id是否可用，然后调用find()方法。

public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    if(empty($user_id)){
        echo "Not able to access this method";
        die();
    }
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}
