<?php foreach ($photos as $photo): ?>
        <?php
            $items[] = ['content' => '<div class="col-md-3 col-sm-4 col-xs-6 thumb">
                <img class="img-responsive" data-id="1" data-sort="13" src="'.Yii::$app->request->hostInfo.'/uploads/thumbnails/'.$photo->name.'" width="150px"/></div>'];
        ?>
    <?php endforeach; ?>
//я вывожу в витжет свои картинки, где перетаскивая их вызываю sortgallery( ) вот в нее то я и хочу передать свои data-//id и data-sort
<?php echo Sortable::widget([
    'type'=>'grid',
    'pluginEvents' => [
        'sortupdate' => 'function() { sortgallery(); }',
    ],
    'items' =>$items,
]);?>
