I have succeeded in deleting multiple rows in gridview Yii2 by doing the following:
Create button in index.php
<p>
<button type="button" onclick="getRows()" class="btn btn-success">Delete Bulk</button>
</p>
Add javascript code in index.php to perform the event of getting the checked rows from the GridView widget.
<script>
function getRows()
{
//var user_id as row_id from the gridview column
// var list = [] is an array for storing the values selected from the //gridview
// so as to post to the controller.
var user_id;
var list = [];
//input[name="selection[]"] this can be seen by inspecting the checkbox from your //gridview
$('input[name="selection[]"]:checked').each(function(){
user_id = this.value;
list.push(user_id);
});
$.ajax({
type: 'post',
url:'index.php?r=student-detail-update/bulk',
data: {selection: list},
});
}
</script>
Put this code in your contoller
if ($selection=(array)Yii::$app->request->post('selection')) {
foreach($selection as $id){
$StudentDetailUpdates = StudentDetailUpdate::find()
->where(['user_id' => $id])
->all(); //....put your staff here
}
