選擇數據從數據庫中的表2的條件CakePHP的

Question

我有兩個表Standards和Topics，Standard包含id, user_id, name和Topics包含id, user_id, name, school_id。

我想從用戶登錄條件中檢索Standards和Topics中的數據。所以用戶只能看到他們的學校名稱。

錯誤：錯誤是，它將顯示學校名稱屬於所有用戶，而不僅僅是登錄用戶。

我想顯示登錄的學校名稱用戶。

這是我的控制器：

public function admin_subject_list($standard_id = null) 
{ 
    $this->loadModel('Subject'); 
    $this->Subject->bindModel(array(
         'belongsTo'=>array(
          'Standard' 
         ), 
         'hasMany'=>array(
          'Topic' 
         ) 
    ),false); 

    $standard_data = $this->Standard->find('first',array('conditions'=>array('Standard.id'=>$standard_id))); 

    $filters  = array('Topic.id'=>$this->Auth->user('id')); 

    $filter = array('Subject.standard_id'=>$standard_id); 
    $data = $this->Subject->find('all',array('conditions'=>$filter));  
    $this->set(compact('data','standard_id','standard_data')); 
    $this->set('title_for_layout', __('Standards', true));  
} 

這是我的看法文件standartd_list.ctp

<?php 
    } 
    // pr($data); 
    $color = array('bg-kypta','bg-green','bg-aqua','bg-uni-n','bg-light-blue','bg-orange','bg-ferozi','bg-light-bluen','bg-light-yellow','bg-teal','bg-maroon'); 
    foreach($data as $key=>$value) 
    { 
     $random = rand(0,10); 
     $get_subscribe_subject = $this->General->getSubscribeTutor($value['Subject']['id']); 
     if(empty($get_subscribe_subject))

Answer 1

你被檢查登錄的用戶與題目的ID。所以，在你的情況下，你需要檢查登錄用戶的ID與主題的user_id。

public function admin_subject_list($standard_id = null) 
{ 
    $this->loadModel('Subject'); 
    $this->Subject->bindModel(array(
        'belongsTo'=>array(
         'Standard' 
        ), 
        'hasMany'=>array(
         'Topic' 
        ) 
    ),false); 

    $standard_data = $this->Standard->find('first',array('conditions'=>array('Standard.id'=>$standard_id))); 

    $this->Subject->Behaviors->load('Containable'); 
    $userId = $this->Auth->user('id'); 
    $filters = array('Subject.standard_id'=>$standard_id); 
    $data = $this->Subject->find('all',array('conditions'=>$filters, 'contain' => array('Standard', 'Topic' => array('conditions' => array('Topic.user_id' => $userId))))); 

    $this->set(compact('data','standard_id','standard_data')); 
    $this->set('title_for_layout', __('Standards', true));  
} 

Answer 2

它看起來像你使用CakePHP 2.x的，對不對？這也有點不清楚你在問什麼，但我相信你應該只能使用標準find() s。

I want to display school name user who log on.

$topics = $this->Topic->find('all', [ 
    'conditions' => [ 
     'user_id' => $this->Auth->user('id') 
    ] 
]); 
$standards = $this->Standard->find('all', [ 
    'conditions' => [ 
     'user_id' => $this->Auth->user('id') 
    ] 
]); 

這會發現，關聯w的用戶登錄/所有主題，以及與登錄的用戶相關聯的所有標準。

或者，你甚至可以用在蛋糕中可用的動態查找器簡化它：

$topics = $this->Topic->findByUserId($this->Auth->user('id')); 
$standards = $this->Standard->findByUserId($this->Auth->user('id'));
