Yii2: Select2, How to set initValueText in Gridview or Tabularform? - yii2

Question

I need to set initValueText for Select2, which is in loop, like gridview or Tabularform. but I don't know how to set right value for each.
<?= TabularForm::widget([
'dataProvider' => $dataProvider,
'form' => $form,
'actionColumn' => false,
'checkboxColumn' => false,
'attributeDefaults' => [
'type' => TabularForm::INPUT_RAW,
],
'attributes' => [
'test' => [
'type' => Form::INPUT_WIDGET,
'widgetClass' => Select2::className(),
'options' => [
'name' => 'test',
'options' => [
'class' => 'test-to-select',
],
'pluginOptions' => [
'allowClear' => true,
'minimumResultsForSearch' => 'Infinity',
'ajax' => [
'url' => Url::to(['/test/get-list']),
'dataType' => 'json',
'data' => new JsExpression('function(term,page) {
return {term : term.term};
}'),
'results' => new JsExpression('function(data,page) {
return {results:data.results};
}'),
'cache' => true
]
],
'initValueText' => 'Selected Text' /// how can I set this in gridview or Tabularform?
],
],
]
]) ?>
Of course this is not working,
'initValueText' => function($model){
retur $model->textValue;
}
Any help would be appreciated.

Answer 1

Into tabularform if you want dynamic initValueText, you can use options closure in this manner:
'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
]
],
];
}
],

Answer 2

If for example attribute for city, so try this..
$cityDesc = empty($model->city) ? '' : City::findOne($model->city)->description;
'initValueText' => $cityDesc, // set the initial display text
For init value first assign value to $model attribute, if you should not assign so this attribute can take value.

Answer 3

Set the data parameter with the array including the option you want to show. For example for cities:
'options' => [
'data' => \yii\helpers\ArrayHelper::map(\app\models\City::find()->orderBy('id')->asArray()->all(), 'id', 'name'),
]

Answer 4

try to put inside the options instead ouside
'widgetClass' => Select2::className(),
'options' => [
'initValueText' => 'Selected Text'

Answer 5

Don't use isset it return error if more the one filter are use there.
[
'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}; }'),
],
],
]),
],
