在 kartik dynagrid 中设置空文本

问题描述

我正在使用 kartik dynagrid，我想设置一个文本，显示数据提供程序何时返回空

网格

echo DynaGrid::widget(['列' =>$列，'showPersonalize' =>真的，'emptyText'=>'Sorry all pr has priitems',////------------------这是我设置的'选项' =>['id' =>'assignsolic-grid'],'gridOptions' =>['选项' =>['id' =>'网格']，'数据提供者' =>$数据提供者，'过滤器模型' =>$搜索模型，'showPageSummary'=>false,'寻呼机' =>['firstPageLabel' =>'第一的'，'lastPageLabel' =>'最后的'，'maxButtonCount' =>10、],'面板' =>['类型' =>GridView::TYPE_PRIMARY,//'标题' =>'<h3 class="panel-title"><i class="glyphicon glyphicon-book"></i></h3>','before'='=>'选择要分配请求的Prs，然后单击分配请求按钮'，'之后' =>Html::button(' <i class=" glyphicon glyphicon-road "></i> Assign Solicitation ', ['value' => Url::to('assignsolc'),'class' =>; 'btn btn-danger', 'id' => 'assignsolic']),'页脚' =>错误的],'工具栏' =>[['内容' =>'{dynagridFilter}{dynagridSort}{dynagrid}'],'{出口}'，'{切换数据}'],'pjax' =>真的，'有边界' =>错误的，'条纹' =>真的，'浓缩' =>真的，'响应' =>真的，'responsiveWrap' =>错误的，'containerOptions'=>['style'=>'overflow:scroll'],]]);

这会返回设置未知属性的错误:kartik\dynagrid\DynaGrid::emptyText How can I set the empty text

解决方案

可以直接在confi/main.php格式化组件中定义空显示的值

'components' =>[......'格式化程序' =>['类' =>'yii\i18n\格式化程序','日期格式' =>'dd.MM.yyyy','decimalSeparator' =>',','千分隔符' =>' ','货币代码' =>'欧元'，'空显示' =>'',//**** 这个参数],.....

否则，如果小部件没有提供适当的属性，您可以使用匿名函数获取值

['属性' =>'你的属性','价值' =>功能($模型){如果( $model->your_attribute == NULL){return '对不起，所有 pr 都有 pitems';} 别的 {返回 $model->your_attribute;}},],

Am using kartik dynagrid and i would like to setup a text that shows when the dataprovider returns empty

The grid

echo DynaGrid::widget([
            'columns' => $columns,
            'showPersonalize' => true,
         'emptyText'=>'Sorry all pr have pritems',///-----------------This is what i had set
            'options' => ['id' => 'assignsolic-grid'],
            'gridOptions' => [
                'options' => ['id' => 'grid'],
                'dataProvider' => $dataProvider,
                 'filterModel' => $searchModel,
                 'showPageSummary'=>false,
                'pager' => [
                    'firstPageLabel' => 'First',
                    'lastPageLabel' => 'Last',
                    'maxButtonCount' => 10,
                ],
                   'panel' => [
             'type' => GridView::TYPE_PRIMARY,
                       // 'heading' => '<h3 class="panel-title"><i class="glyphicon glyphicon-book"></i> </h3>',
                      'before'=>'<i>Select the Prs to assign solicitation and then click the Assign Solicitation button</i>',
                      'after' =>

        Html::button(' <i class=" glyphicon glyphicon-road "></i> Assign Solicitation ', ['value' => Url::to('assignsolc'),'class' => 'btn btn-danger', 'id' => 'assignsolic']),

                        'footer' => false
                    ],
                'toolbar' => [
                    ['content' => '{dynagridFilter}{dynagridSort}{dynagrid}'],
                    '{export}',
                    '{toggleData}'
                ],
                'pjax' => true,
                'bordered' => false,
                'striped' => true,
                'condensed' => true,
                'responsive' => true,
                'responsiveWrap' => false,
                'containerOptions'=>['style'=>'overflow:scroll'],
            ]
        ]) ;

This returs an error of Setting unknown property: kartik\dynagrid\DynaGrid::emptyText how can i set the empty text

解决方案

You can define the value for null display directly in confi/main.php formatter component

'components' => [
   .......
        'formatter' => [
        'class' => 'yii\i18n\Formatter',
        'dateFormat' => 'dd.MM.yyyy',
        'decimalSeparator' => ',',
        'thousandSeparator' => ' ',
        'currencyCode' => 'EUR',
        'nullDisplay' => '',           // **** this param 
    ],
 ..... 

Otherwise if the widget don't provide a proper attribute you can use an anonymous function for value

  [
    'attribute' => 'your_attribute',
    'value' => function ($model) {
        if ( $model->your_attribute == NULL) {
            return  'Sorry all pr have pritems';
        } else {
            return $model->your_attribute;
       }
     },
  ],
