Yii2 Basic- How to display data table in looping using model? - php

Question

I'm trying to display a loop of data (in table form) for child data to be display in parent view. Below is the code for the table view:
//display child data loop
<div class="col-md-6 col-xs-12">
<div class="box">
<div class="box-header">
<h3 class="box-title">Details</h3>
</div>
<div class="box-body">
<div class="table-responsive">
<table class="table table-bordered table-striped">
<thead>
<tr>
<th class="text-center">Code</th>
<th>Part Number</th>
<th>Quantity</th>
<th>Size</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<?php
foreach($modelsMaintenanceItem as $i => $modelMaintenanceItem)
{
?>
<tr>
<td class="text-center"><?php echo $modelMaintenanceItem->Code; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Part_Number; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Quantity; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Size; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Description; ?></td>
</tr>
<?php
}
?>
</tbody>
</table>
</div>
</div>
</div>
</div>
Inside controller for function actionView, the code are as below:
public function actionView($id)
{
$searchModel = new MaintenanceSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
// $model = new Maintenance();
$modelsMaintenanceItem = [new MaintenanceItem]; //pass model to be use in view page
return $this->render('view', [
'model' => $this->findModel($id),
'modelsMaintenanceItem' => $this->findModel($id),
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
// 'modelsMaintenanceItem' => (empty($modelsMaintenanceItem)) ? [new MaintenanceItem] : $modelsMaintenanceItem //pass model to be use in view page
]);
}
Help me please... I'm Stuck here. I think I need to do some changes in controller for function actionView, about 'modelsMaintenanceItem' but I'm not sure what should I put there.

If you want really accessing to dataProvider models you should use
$models = $dataProvider->getModels();
and for html code inside a foreach, suggest also the echo of the html code or use the alternative syntax for control structures eg: <?php foreach(...) : ?> ... <?php endforeach; ?> syntax
eg:
<?php
$models = $dataProvider->getModels();
foreach($models as $i => $modelMaintenanceItem):
?>
<tr>
<td class="text-center"><?php echo $modelMaintenanceItem->Code; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Part_Number; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Quantity; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Size; ?></td>
<td class="text-center"><?php echo $modelMaintenanceItem->Description; ?></td>
</tr>
<?php endforeach; ?>
anyway the simplest way for show a table in Yii2 is based on gridview
<?php
use yii\grid\GridView;
?>
...
<?php
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'Code',
'Part_Number',
'Quantity',
'Size',
'Description',
],
]); ?>
