YII2 implementation of simultaneous search for multiple fields _php instance

The example in this article describes how YII2 implements searching multiple fields at the same time. Share to everyone for your reference, specific as follows:

The search field in Yii2 is a andfilterwhere This method that can be used to search for a paragraph.

If you are searching for more than one field, such as searching for the title of the article and the content of the article to include keywords to search for, because their relationship is or, so you need to use the orfilterwhere method

Here's the whole code.

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 ' =>
  ]);
  $model = $post->offset ($pages->offset)->limit ($pages->limit)->all ();
  return $this->render (' index ', [
    ' model ' => $model,
    ' pages ' => $pages,
  ]);
}

You can see the SQL statement as follows:

Copy Code code as follows:

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 '. * ' 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
