Search in gridview yii2 using a button not with form - php

Question

I have a gridview with pjax.
<div class="request-index">
<div id="ajaxCrudDatatable">
<?=
GridView::widget([
'id' => 'crud-datatable',
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'pjax' => true,
'columns' => require(__DIR__ . '/_columns.php'),
'toolbar' => [
['content' =>
Html::a('<i class="glyphicon glyphicon-plus"></i> Add Request', ['create'], ['role' => 'modal-remote', 'title' => 'Create new Requests', 'class' => 'btn btn-success']) .
Html::a('<i class="glyphicon glyphicon-repeat"></i> Reload', [''], ['data-pjax' => 1, 'class' => 'btn btn-primary', 'title' => 'Reset Grid']) .
'{toggleData}' .
'{export}'
],
],
'panel' => [
'type' => 'primary',
'heading' => '<i class="glyphicon glyphicon-list"></i> Requests listing',
'before' => '<button type="button" class="btn btn-danger btn-secondary"> Belum Selesai : <strong>'. $count_request_belum_selesai .'</strong> </button>',
'after' => BulkButtonWidget::widget([
'buttons' => Html::a('<i class="glyphicon glyphicon-trash"></i> Delete All', ["bulk-delete"], [
"class" => "btn btn-danger btn-xs",
'role' => 'modal-remote-bulk',delete this item'
]),
]) .
'<div class="clearfix"></div>',
]
])
?>
</div>
if you see from code above, please concern with
'before' => '<button type="button" class="btn btn-danger btn-secondary"> Not finished : <strong>'. $count_request_belum_selesai .'</strong> </button>',
When this button is clicked, I want to running a function in my model named RequestSearch :
public function searchRequestBelumSelesai(){
$query = Request::findAll(['tanggal_selesai' => NULL]);
return $query;
}
Which is the gridview will be displayed the result, is it possible ?

Answer 1

In the action of the controller that will receive the click of your button, you must modify the dataProvider given to the View, so that it looks like something like this:
$dataProvider= new ActiveDataProvider([
'query' => $your_model->searchRequestBelumSelesai(),
]);
