In an ActiveDataProvider you can use closures as values, like:
$dataprovider = new ArrayDataProvider([
'allModels' => $array
]);
$gridColumns = [
'attrib_1',
[
'attribute' => 'attrib_2',
'label' => 'Label_2',
'value' => function($model) {
return Html::encode($model->value_2);
}
],
'attrib_3'
];
echo GridView::widget([
'dataProvider'=> $dataprovider,
'columns' => $gridColumns
]);
Is it possible to do the same or something like this, in an ArrayDataProvider?
Yes. Only difference is that $model is not an object but array so:
'value' => function($model) {
return Html::encode($model['value_2']);
}
