Yii2-advanced : ArrayDataProvider - php

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']);
},
],
]
]);
}
?>

Answer 1

Controller
public function actionIndex()
{
$query = new \yii\db\Query;
$dataProvider = new ArrayDataProvider([
'allModels' =>$query->from('business_main_categories')->all(),
]);
return $this->render('index', [
'dataProvider' => $dataProvider,
]);
}
Index
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
[
'attribute' => 'bmc_image',
'format' => 'html',
'value' => function ($data) {
return Html::img($data['bmc_image'],['width' => '210px', 'height' => '190px']);
},
],
],
]); ?>

Answer 2

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.
