yii2 - How to get checked checkbox values from gridview to controller - php

Question

I need to get checked checkbox value from my view to controller when button is press.
Gridview :
<div class="installment-ready">
<!-- <h1><?= Html::encode($this->title) ?></h1> -->
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<?= GridView::widget([
'dataProvider' => $dataProvider,
//'filterModel' => $searchModel,
'columns' => [
[
'class' => 'yii\grid\SerialColumn',
'contentOptions'=>[ 'style'=>'width: 60px'],
],
//Checkbox
[
'class' => 'yii\grid\CheckboxColumn',
'contentOptions'=>[ 'style'=>'width: 50px'],
'name' => 'checked',
'checkboxOptions'=> function($model, $key, $index, $column) {
return ["value" => $model->ACCOUNT_ID];
}
],
Button to process selected checkbox:
<?= Html::a('Submit', ['#'], ['class' => 'btn btn-success pull-right']) ?>

Answer 1

In your controller action use below code
Yii::$app->request->post('checked');

Answer 2

I found a solution. I'm using ajax to post selected checkbox to my controller.
Script that I use in my view
<script type="text/javascript">
// action for all selected rows
function submit(){
var dialog = confirm("Are you sure to submit the installment?");
if (dialog == true) {
var keys = $('#grid').yiiGridView('getSelectedRows');
// console.log(keys);
var ajax = new XMLHttpRequest();
$.ajax({
type: "POST",
url: 'index.php?r=installment/submit', // Your controller action
data: {keylist: keys},
success: function(result){
console.log(result);
}
});
}
}
</script>
<!-- Submit button -->
<button type="button" onclick="submit()" class="btn btn-success pull-right">Submit</button
And you can use usual Yii::$app->request->post() in controller to get your data.
