Question

如何在find（）方法中添加多个字段进行排序？

我试过如下

$model::find()->orderBy([['id_date' => SORT_DESC],['item_no'=>SORT_ASC]);

但它在查询时抛出错误。由yii2生成的Orderby Query是：ORDER BY 0, 1

Answer 1

根据documentation：

$model::find()->orderBy([
  'id_date' => SORT_DESC,
  'item_no'=>SORT_ASC
]);

Answer 2

以下代码中有语法错误：

$model::find()->orderBy([['id_date' => SORT_DESC], ['item_no' => SORT_ASC]);

正确的方法是：

$model::find()->orderBy(['id_date' => SORT_DESC, 'item_no' => SORT_ASC]);

Answer 3

class NewsController extends Controller
{

    public function actionIndex ()
    {   $news = \common\models\News::find()->orderBy(['date' => SORT_DESC])->all();
        return $this->render("index",[
            'news' => $news
        ]);
    }
}
