本文实例讲述了Yii2实现同时搜索多个字段的方法。分享给大家供大家参考,具体如下:
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

public function actionIndex()
{
$key =Yii:: $app ->request->post( "key" );
$query = Post::find()->joinWith( 'cate' );
$post = $query ->orderBy([ 'post.id' => SORT_DESC])->asArray()->where([ 'post.status' => 1]);
if ( $key ){
$post ->andFilterWhere([ 'like' , 'post.title' , $key ])
->orFilterWhere([ 'like' , 'post.content' , $key ]);
}
$pages = new Pagination([
'totalCount' => $post -> count (),
'defaultPageSize' => 10
]);
$model = $post ->offset( $pages ->offset)->limit( $pages ->limit)->all();
return $this ->render( 'index' , [
'model' => $model ,
'pages' => $pages ,
]);
}

可以看到sql语句如下:
复制代码 代码如下:
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
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
希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
