Yii2 Gridview with popup

Modal pop up in grid view in yii2

I am going to show you how to  implement Gridview with popup.

Insert this code your header section.

use yii\helpers\Url;  
use yii\bootstrap\Modal;

Define modal and Register this JS into you'r index file

Add Modal code above GridView code.

<?php

Modal::begin([

    'id' => 'myModal',

    'header' => '<h4 class="modal-title">...</h4>',

]);

 

echo '...';

 

Modal::end();

?>

And than register JavaScript at top or bottom of view page.

$this->registerJs("

    $('#myModal').on('show.bs.modal', function (event) {

        var button = $(event.relatedTarget)

        var modal = $(this)

        var title = button.data('title')

        var href = button.attr('href')

        modal.find('.modal-title').html(title)

        modal.find('.modal-body').html('<i class=\"fa fa-spinner fa-spin\"></i>')

        $.post(href)

            .done(function( data ) {

                modal.find('.modal-body').html(data)

            });

        })

");

Insert code into gridview column section

return  Html::a($count,['detail','group_id'=>$data->id],[

          'data-toggle'=>"modal",

          'data-target'=>"#myModal",

          'data-title'=>"Detail Data",

        ]);

Inset code into your controller

return $this->renderAjax('detail', [

    'searchModel' => $searchModel,

    'dataProvider' => $dataProvider,

]);
