Question

我有一个问题，如何使用条件WHERE在YII2中使用Closure类型Active记录查询。

这是我想要实现的目标：

public function getUsers($limit = 10, $type = 1, $company_id = 0) { 
    return User::find()->where( function($query) use ($type, $company_id){       
                $query->where(['type' => $type]); 
                if($company_id != 0) { 
                   $query->andWhere(['company_id' => $company_id]); 
                } 
               })
            ->orderBy([ 'created_at'=> SORT_DESC, ]) 
            ->limit($limit); 
}

如果有人知道这一点，请提供帮助。

无法弄清楚Closure的用途。您可以将andFilterWhere()用于company_id条件，但是您应该将其设置为默认值为null，因此如果未初始化company_id，则会忽略此条件：

public function getUsers($limit = 10, $type = 1, $company_id = null) { 
    return User::find()
            ->where(['type' => $type])
            ->andFilterWhere(['company_id' => $company_id])
            ->orderBy([ 'created_at'=> SORT_DESC ]) 
            ->limit($limit)
            ->all(); //probably you muiss it
}

public function getUsers($limit = 10, $type = 1, $company_id = null) 
{
       $query =User::find()
            ->where(['type' => $type])
            ->orderBy([ 'created_at'=> SORT_DESC ]) 
            ->limit($limit)
            ->all(); 

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);

      // then filter data
      if($company_id != null)
          $query->andFilterWhere(['company_id' => $company_id]);
}

我在Laravel MVC中遇到了同样的问题，这样的事情对我来说还不错。

替换

$query->andWhere(['company_id' => $company_id]);

带

$query->where(['company_id' => $company_id]);

YII2中的多个where子句
