Yii2- Select2 按钮作为网格视图过滤器不过滤

Question

我想在 Yii Grid 视图中使用 Select2 dr 作为过滤器，但它根本不过滤，只刷新页面。

我从 2 个表中获取数据 - 我只从帐户中获取 user_id，而从学分中我获取所有其他内容。每个过滤器都有效，除了'user_id'一个。

<?php

 echo GridView::widget(
     [
         'dataProvider' => $dataProvider,
         'filterModel' => $searchModel,
         'columns' => [
             [
                 'attribute' => 'wp_id',
                 'value' => 'accounts.user_id',
                 'filter' => Select2::widget(
                     [
                         'model' => $searchModel,
                         'attribute' => 'wp_id',
                         'data' => ArrayHelper::map(Accounts::find()->all(), 'wp_id', 'user_id'),
                         'options' => ['placeholder' => ' --Filter by user id-- '],
                         'language' => 'en',
                         'pluginOptions' => [
                             'allowClear' => true,
                         ],
                     ]
                 ),
             ],
         ],
     ]
); ?>

这是控制器中的动作。

<?php
 public function actionIndex()
    {

        $searchModel = new CreditsSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        return $this->render('index', [
            'searchModel' => $searchModel,
            'dataProvider' => $dataProvider,
        ]);
    } ?>

这是搜索模型方法

<?php   
public function search($params)
    {
        $query = Credits::find()->with('accounts');

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

        $this->load($params);

        if (!$this->validate()) {
            // uncomment the following line if you do not want to return any records when validation fails
            // $query->where('0=1');
            return $dataProvider;
        }
        if(!empty($this->user_id)) {
            $query->andFilterWhere(['=', 'accounts.user_id', $this->user_id]);
        }
        // grid filtering conditions
        $query->andFilterWhere([
            'user_id' => $this->user_id,
            'wp_id' => $this->wp_id,
            'credits_bought' => $this->credits_bought,
            'purchase_date' => $this->purchase_date,
            'id' => $this->id,
        ]);

        return $dataProvider;
    }
} ?>

提前致谢！

因为您在 GridView 过滤器下传递 wp_id 并从 Accounts 模型中选择 wp_id 作为 select2-dropdown [=18 的值=]

ArrayHelper::map(Accounts::find()->all(), 'wp_id', 'user_id')

尽管您使用 gridview 列属性 wp_id 并使用 select2 过滤同一列的 user_id 令人困惑，但如果您希望这样做，您可能需要更改以上为

ArrayHelper::map(Accounts::find()->all(), 'user_id', 'wp_id')
