Yii2同时搜索多个字段

Yii2中搜索字段是用的andFilterWhere这个方法,用它可以搜索一个一段。

如果是搜索多个字段的话 ,比如搜索文章标题和文章内容是是否包含需要搜索的关键词,因为他们两个的关系是or,所以就要用到orFilterWhere这个方法

下面就是全部的代码

  1. public function actionIndex()
  2. {
  3. $key =Yii::$app->request->post("key");
  4.  
  5. $query = Post::find()->joinWith('cate');
  6. $post = $query->orderBy(['post.id' => SORT_DESC])->asArray()->where(['post.status' => 1]);
  7. if($key){
  8. $post->andFilterWhere(['like', 'post.title', $key])
  9. ->orFilterWhere(['like', 'post.content', $key]);
  10. }
  11.  
  12. $pages = new Pagination([
  13. 'totalCount' => $post->count(),
  14. 'defaultPageSize' => 10
  15. ]);
  16. $model = $post->offset($pages->offset)->limit($pages->limit)->all();
  17.  
  18. return $this->render('index', [
  19. 'model' => $model,
  20. 'pages' => $pages,
  21. ]);
  22. }

可以看到sql语句如下

select count(*) from `post` left join `category` on `post`.`cate_id`=`category`.`id` where ((`post`.`status`=1) and (`post`.`title` like '%key%')) or (`post`.`content` like '%key%') order by `post`.`id` desc

select `post`.* from `post` left join `category` on `post`.`cate_id`=`category`.`id` where ((`post`.`status`=1) and (`post`.`title` like '%key%')) or (`post`.`content` like '%key%') order by `post`.`id` desc limit 10
