コントローラ：

public function userdata() 
    { 

     $query = $this->Users->find('all') 
      ->join([ 
       'subsection' => [ 
        'table' => 'subsections', 
        'type' => 'inner', 
        'conditions' => 'users.subsection_id = subsections.id', 
       ], 
       'city' => [ 
        'table' => 'cities', 
        'type' => 'INNER', 
        'conditions' => 'users.city_id = cities.id', 
       ] 
      ]); 

     //$user = $this->Users->get($id); 

     $this->set([ 
      'success' => true, 
      'data' => $query, 
      '_serialize' => ['success', 'data'] 
     ]); 
    } 

私は必要なMySQLはこれです：

SELECT * FROM mydb.users 
INNER JOIN subsections on users.subsection_id = subsections.id 
INNER JOIN cities on users.city_id = cities.id; 

私は仕事NOSバージョンのPHPを変更するが、選択は、テーブルのサブセクションや都市

Answer 1

のために働いていません。このようなクエリの後->toArray();を追加してください：

$query = $this->Users->find('all') 
      ->join([ 
       'subsection' => [ 
        'table' => 'subsections', 
        'type' => 'inner', 
        'conditions' => 'users.subsection_id = subsections.id', 
       ], 
       'city' => [ 
        'table' => 'cities', 
        'type' => 'INNER', 
        'conditions' => 'users.city_id = cities.id', 
       ] 
      ])->toArray(); 

確認してください。それがあなたを助けることを願っています。
