使用条件CakePHP从数据库中的2个表中选择数据

php mysql cakephp

使用条件CakePHP从数据库中的2个表中选择数据,php,mysql,cakephp,Php,Mysql,Cakephp,我有两个表标准和主题，标准包含id、用户id、姓名和主题包含id、用户id、姓名、学校id public function admin_subject_list($standard_id = null) { $this->loadModel('Subject'); $this->Subject->bindModel(array( 'belongsTo'=>array(

我有两个表

标准

和

主题

，

标准

包含

id、用户id、姓名

和

主题

包含

id、用户id、姓名、学校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));      
}

我想根据用户登录条件从

标准

和

主题

检索数据。因此，用户只能看到他们的学校名称

错误：错误是，它将显示学校名称属于所有用户，而不仅仅是登录用户

我想显示登录的学校名称用户

这是我的控制器：

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));      
}

这是我的视图文件standartd_list.ctp

看起来您正在使用CakePHP 2.x，对吗？还有一点不清楚您在问什么，但我相信您应该能够使用标准的find（）
s
我想显示登录的学校名称用户
这将查找与登录用户关联的所有主题，以及与登录用户关联的所有标准
或者，您甚至可以使用Cake中提供的动态查找器来简化它：
$topics = $this->Topic->findByUserId($this->Auth->user('id'));
$standards = $this->Standard->findByUserId($this->Auth->user('id'));

您正在使用主题id检查登录用户id。因此，在您的情况下，您需要使用主题的用户id检查登录用户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));      
}

是的，我正在使用CakePHP2.x。我改变了$data=$this->Subject->findByUserId（$this->Auth->user（'id'）；但它什么都没有。请告诉我应该删除或更改哪一行可以显示$data
的调试吗？当我编译程序时，将显示所有用户的学校名称，而不仅仅是用户日志on@Rik.esh你好我忘了我在generalhelper.php中还有一个函数请查看并帮助我错误：未找到列：1054未知列“where子句”中的“Topic.user_id”，但我确信Topics表包含user_id，我已使用containable with conditions更新了答案。请检查。它仍然显示所有用户学校名称，而不仅仅是用户登录。对不起，兄弟，你的问题让我越来越困惑。
