我遇到了过滤问题。我创建了一个网格视图，其中包含来自相关表的数据列表。 我面临的是：
如何对数据进行排序（我只能对从父表中接收的数据进行排序）？
为什么搜索总是返回相同的值，无论我在过滤器中写入，即使使用Pjax重新加载但没有数据更改？
我的观点：
<div class="row">
<div class="col-lg-12">

这是我从控制器发送的内容：
$SearchItemsSupplieirs = new \app\models\ItemsSupplieirs;
$dataProvider = $SearchItemsSupplieirs->search(Yii::$app->request->getQueryParams('ItemsSupplieirs'));
return $this->render('listitems', [
'dataProvider' => $dataProvider,
'searchModel' => $SearchItemsSupplieirs,
]);

艾哈迈德：
我注意到的第一件事是，在你的搜索方法中，你实际上并没有查询任何传入的搜索参数。这就是为什么无论你在网格中做什么，你都能得到相同的结果。
您正在通过$ this-＆gt; load（$ params）加载搜索参数，但在创建ActiveDataProvider之前，您不会添加到查询语句中。
以下是如何构建搜索方法的示例：
public function search($params)
{
$query = Client::find()
->joinWith(['venues','events'])
->orderBy('name');
$this->load($params);
if(strlen($this->status) > 0){
if($this->status <> -1)
$query->andWhere(['status' => $this->status]);
}
if(!empty($this->name)){
$query->andFilterWhere(['like','client.name',$this->name])
->orFilterWhere(['like','venue.name',$this->name]);
}
if(!empty($this->status)){
if($this->status != -1){
$query->andWhere(['status' => $this->status]);
}
}
if(!empty($this->address1)){
$query->andFilterWhere(['like','address1',$this->address1])
->orFilterWhere(['like','address2',$this->address1])
->orFilterWhere(['like','city',$this->address1])
->orFilterWhere(['like','state',$this->address1])
->orFilterWhere(['like','zip',$this->address1]);
}
if(!empty($this->venues)){
$query->andWhere(['like','venue.name',$this->venues]);
}
if(!empty($this->staffing_manager)){
$query->andWhere(['venue.staffing_manager_id' => $this->staffing_manager]);
}
if(!empty($this->sales_rep)){
$query->andWhere(['venue.sales_rep_id' => $this->sales_rep]);
}
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => false,
]);
$dataProvider->sort->attributes['name'] = [
'asc' => ['name' => SORT_ASC],
'desc' => ['name' => SORT_DESC]
];
$dataProvider->sort->attributes['last_event'] = [
'asc' => ['date' => SORT_ASC],
'desc' => ['date' => SORT_DESC]
];
return $dataProvider;
}
