Yii2：如何使用GridView中的條件窗口小部件

Question

我的項目中有一個Gridview窗口小部件，其中'filterModel' => $searchModel,向用戶顯示了一個過濾器字段和用於加載動作按鈕的動作列。我的問題是，我想通過控制器的兩個獨立的操作來重用此Gridview。一個動作，即index操作會加載用戶的數據，並允許用戶使用過濾器字段進行過濾，並在動作列中執行各種操作。其他controller action用於報告。這會生成一個pdf報告，我不希望過濾器字段和操作列出現在報告中。 有沒有辦法將條件傳遞給Gridview，而無需使用if else重寫整個代碼，因爲我發現這在使用的代碼量方面是無效的。這是我迄今爲止編寫的代碼，但需要使用最少代碼的簡短格式。

的index.php

<?php 

$action_id = Yii::$app->controller->action->id; 

if ($action_id == 'index') { 
    \yiister\adminlte\widgets\grid\GridView::widget([ 
     'dataProvider' => $dataProvider, 
     'filterModel' => $searchModel, 
     "condensed" => false, 
     "hover" => true, 
     'columns' => [ 
      ['class' => 'yii\grid\SerialColumn'], 
      'name', 
      'mobile_number', 
      'sex', 
      [ 
       // the attribute 
       'attribute' => 'date', 
       // format the value 
       'value' => function ($model) { 
        if (extension_loaded('intl')) { 
         return Yii::t('app', '{0, date, MMMM dd, YYYY HH:mm}', [$model->date]); 
        } else { 
         return date($model->date); 
        } 
       }, 
       // some styling? 
       'headerOptions' => [ 
        'class' => 'col-md-2' 
       ], 
       // here we render the widget 
       'filter' => DateRangePicker::widget([

Answer 1

要隱藏過濾器使用短的語法，如果條件：

'filterModel' => $myCondition ? $searchModel : null, 

要隱藏ActionColumn使用visible屬性：

[ 
    'class' => 'yii\grid\ActionColumn', 
    'visible' => $myCondition ? true : false, 
    // here rest of your code 
],
