Yii2:如何在 GridView Widget 中使用条件

Yii2: How to use conditions inside GridView Widget

我的项目中有一个带有 'filterModel' => $searchModel, 的 Gridview 小部件,它向用户显示筛选字段和用于加载操作按钮的操作列。我的问题是,我想通过控制器的两个独立操作重用这个 Gridview。一个动作,即 index 动作为用户加载数据,并允许用户使用过滤器字段进行过滤,并在操作列中执行各种操作。另一个 controller action 用于报告。这会生成一个 pdf 报告,我不希望过滤器字段和操作列出现在报告中。 有没有一种方法可以将条件传递给 Gridview 而不必使用 if else 重写整个代码,因为我发现这在使用的代码量方面是无效的。这是我到目前为止编写的代码,但需要代码最少的更短形式。

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?

                      }
                    } 
                ],            
            ],  // fin ActionColumn
        ],
    ]);
} else {
    \yiister\adminlte\widgets\grid\GridView::widget([
        'dataProvider' => $dataProvider,
        "condensed" => false,
        "hover" => true,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],

                    'class' => 'col-md-2' 
                ], 
                // here we render the widget 
                'filter' => DateRangePicker::widget([

                    'attribute' => 'date_range',
                    'pluginOptions' => [ 
                        'format' => 'd-m-Y', 
                        'autoUpdateInput' => false 
                    ] 
                ]) 
            ],
            [
            'attribute' => 'officer',
            'value' => 'officer.first_name'
            ],
        ],
    ]);
}

如果条件为:

,则使用简短语法隐藏过滤器
'filterModel' => $myCondition ? $searchModel : null,

要隐藏 ActionColumn 使用 visible 属性:

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