Question

我有桌子名为书籍，想在书籍视图中显示“相关书籍”。

books table
`book_id`
`isbn`
`book_name`
`author_name`
`Date`
`number`
`language`
`Translator`
`abstract`
`picture`
`created_at`

控制器代码

public function actionView($id)
{
    $model=$this->findModel($id);
    $dataProvider=$this->related($model);
    return $this->render('view', [
        'model' => $model,
        'dataProvider' => $dataProvider,
    ]);
}
protected function related($model)
{
    $query = Books::find();
    $query->select('book_id,picture, book_name,author_name,(( author_name LIKE \'%'.$model->author_name.'%\')+( book_name LIKE \'%'.$model->book_name.'%\')) as total')
    ->orFilterwhere(['or like','author_name' , explode(' ',$model->author_name)])
    ->orFilterwhere(['or like','book_name' , explode(' ',$model->book_name)])
    ->orderBy('total')
    ->limit(25);

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

问题： book_name LIKE \'%'.$model->book_name.'%\'不接受数组。像LIKE \'%'.explode(' ',$model->book_name).'%\'之类的东西它必须是一个正常工作的数组。如何在选择条件下使用数组。或者告诉我一些其他方法来获得最佳匹配结果。 TNX

Answer 1

首先如果你想要Total，则无需在select

中写入条件

$query->select('book_id,picture, book_name,author_name,(book_name+author_name) as total');

$model->author_name $model->book_name是数组所以你可以这样做。

protected function related($model)
{
    $query = Books::find();
    $query->select('book_id,picture, book_name,author_name,(book_name+author_name) as total');

     $author_names=  explode(' ',$model->author_name);
     foreach($author_names as $author_name)
     {
      $query->orFilterwhere(['like','author_name' , $author_name]);
     }

     $book_names=explode(' ',$model->book_name);
     foreach($book_names as $book_name)
     {
      $query->orFilterwhere(['like','book_name' , $book_name]);
     }
    ->orderBy('total')
    ->limit(25);

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

您需要使用MySQL match() against()功能（或者如果您使用不同的数据库，则替换）。
