Yii2-advanced：ArrayDataProvider

Question

I want to use ArrayDataProvider with the following code of siteController. I wrote the following code but it doesn't work. Here is my actionIndex :

public function actionIndex()
{
        $query = new \yii\db\Query;
        $query->select('*')->from('business_main_categories');
        $query->createCommand();

        $dataProviders = [];

        foreach ($query as $category) {
            $dataProviders[] = new ArrayDataProvider([
                'allModels' => $category,
                'sort' => false,
                'pagination' => false,
            ]);
        }

        return $this->render('index', [
            'dataProvider' => $dataProviders,
        ]);
}

And want it to iterate in gridView. So, I wrote the following code (I don't know whether it's correct or not) :

Here is my index.php :

<?php
    $dataProviders[] = 'dataProvider';
    foreach ($dataProviders as $dataProvider) {
        echo GridView::widget([
            'dataProvider' => $dataProvider,
            'summary' => '',
            'columns' => [
                [
                        'attribute' => 'bmc_image',
                        'format' => 'html',
                        'label' => '',
                        'value' => function ($data) {
                            return Html::img($data['bmc_image'],
                                ['width' => '210px', 'height' => '190px']);
                        },
                    ],
                ]
       ]); 
    } 
?>

I solved my problem without using gridview. As follows -

My SiteController -

public function actionIndex()
{
        $searchModel = new BusinessMainCategoriesSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
        $dataProvider->pagination->pageSize = $dataProvider->getTotalCount();   //-1 : disable

        return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
        ]);
}

using this code I get all records in dataProvider from my db. (Note that, I'm using ActiveDataProvider in my 'BusinessMainCategoriesSearch' model)

And, my index.php is -

<?php
    $m = $dataProvider->getModels();
    foreach ($m as $dp) {
        echo "<img src = '".$dp['bmc_image']."' />";
        echo '<center><font color = "white">'.$dp['bmc_name'].'<font/></center>';
    } 
?>

It worked great for me & it's a easiest way to do so.
