Question

我需要为Select2设置initValueText，它在循环中，如gridview或Tabularform。但我不知道如何为每个人设定正确的价值。

<?= TabularForm::widget([
    'dataProvider' => $dataProvider,
    'form' => $form,
    'actionColumn' => false,
    'checkboxColumn' => false,
    'attributeDefaults' => [
        'type' => TabularForm::INPUT_RAW,
    ],
    'attributes' => [
        'test' => [
            'type' => Form::INPUT_WIDGET,
            'widgetClass' => Select2::className(),
            'options' => [
                'name' => 'test',
                'options' => [
                    'class' => 'test-to-select',
                ],
                'pluginOptions' => [
                    'allowClear' => true,
                    'minimumResultsForSearch' => 'Infinity',
                    'ajax' => [
                        'url' => Url::to(['/test/get-list']),
                        'dataType' => 'json',
                        'data' => new JsExpression('function(term,page) {
                            return {term : term.term};
                        }'),
                        'results' => new JsExpression('function(data,page) {
                            return {results:data.results};
                        }'),
                        'cache' => true
                    ]
                ],
                'initValueText' => 'Selected Text' /// how can I set this in gridview or Tabularform?
            ],

        ],
    ]
]) ?>

当然这不起作用，

'initValueText' => function($model){
    retur $model->textValue;
}

任何帮助将不胜感激。

如果你想要动态的initValueText，进入tabularform，你可以用这种方式使用options闭包：

'test' => [
        'type' => Form::INPUT_WIDGET,
        'widgetClass' => Select2::className(),
        'options' => function($model, $key, $index, $widget) {
            $initValueText = empty($model['textValue']) ? '' : $model['textValue'];
            return [
                'name' => 'test',
                'options' => [
                    'class' => 'test-to-select',
                ],
                'initValueText' => $initValueText,
                'pluginOptions' => [
                    'allowClear' => true,
                    'minimumResultsForSearch' => 'Infinity',
                    'ajax' => [
                        'url' => Url::to(['/test/get-list']),
                        'dataType' => 'json',
                        'data' => new JsExpression('function(term,page) {
                            return {term : term.term};
                        }'),
                        'results' => new JsExpression('function(data,page) {
                            return {results:data.results};
                        }'),
                        'cache' => true
                    ]
                ],
            ];
        }
    ],

例如，如果是city的属性，那么试试这个..

$cityDesc = empty($model->city) ? '' : City::findOne($model->city)->description;

'initValueText' => $cityDesc, // set the initial display text

对于初始值，首先为$ model属性赋值，如果不应该赋值，则此属性可以取值。

Answer 3

使用包含您要显示的选项的数组设置data参数。例如，对于城市：

'options' => [
    'data' => \yii\helpers\ArrayHelper::map(\app\models\City::find()->orderBy('id')->asArray()->all(), 'id', 'name'),
]

Answer 4

尝试将选项置于ouside

之内

'widgetClass' => Select2::className(),
'options' => [
    'initValueText' => 'Selected Text'

Answer 5

如果不使用isset，则如果使用了一个过滤器，则会返回错误。

      [
            'attribute' => 'ad_partner_id',
            'value' => function ($model, $key, $index, $widget) {
                return $model->partner->name;
            },
            'filter' => Select2::widget([
                'model' => $searchModel,
                'initValueText' => !empty($searchModel->ad_partner_id) ? $searchModel->partner->name : "",
                'attribute' => 'ad_partner_id',
                'options' => ['placeholder' => Yii::t('app', 'Search  Partner ...')],
                'pluginOptions' => ['allowClear' => true, 'autocomplete' => true,
                    'ajax' => ['url' => Url::base() . '/partner/get-partners',
                        'dataType' => 'json',
                        'data' => new JsExpression('function(params) { return {q:params.term}; }'),
                    ],
                ],
            ]),
        ],

Yii2：Select2，如何在Gridview或Tabularform中设置initValueText？
