我面临过滤问题。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：

  1. 如何对数据进行排序（我只能对从父表接收到的数据进行排序）？

  2. 为什么搜索总是返回相同的值，无论我在过滤器中写入什么，即使 Pjax 重新加载但没有数据更改？

这是我的观点：

<div class="row">
    <div class="col-lg-12">

        <?php

        $ItemSupMod = $ItemSupMod;
        $gridColumns = [

这是我从控制器发送的：

$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，在您的搜索方法中，您实际上并没有查询任何传入的搜索参数。这就是为什么无论您在网格中做什么，都会得到相同的结果。

您正在通过 $this->load($params) 加载搜索参数，但在创建 ActiveDataProvider 之前您没有添加到查询语句中。

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;
}
