View can't call Controller Function Zend Framework 2 - php

Question

I can't call my controller in view page. even if i use print_r in controller but it didn't show. I have body_product.phtml view code:
<table class="table table-hover table-condensed">
<tbody>
<?php
$i = 1;
//print_r("list produk:".$this->productList);
foreach ($this->productList as $data) {
$desc=explode(",",$data['descriptions']);
?>
<tr>
<th colspan="3">
<input type="hidden" id="id_pack" name="id_pack" value="<?php echo $data['package_id']; ?>">
<input type="hidden" id="nama_pack" name="nama_pack" value="<?php echo $data['package_name']; ?>">
<h4 align="center" class="title-pack"><?php echo $data['package_name']; ?></h4>
</th>
</tr>
<tr id="dashe">
<td>
<ul class="myul">
<?php foreach($desc as $descriptions) { ?>
<li class="myli"> <?php echo $descriptions; ?></li>
<?php } ?>
</ul>
</td>
<td>
<h4 class="prize">
<?php setlocale(LC_MONETARY, 'id_ID');
echo money_format('%.2n', $data['package_price']); ?>
/ month
</h4>
</td>
<td>
<p id="btn-hrm" class="mybutton" data-toggle="modal" data-target=".mymodal">Order</p>
</td>
</tr>
<?php
$i++;
}
?>
</tbody>
</table>
and in the indexController:
public function loadProductAction() {
$viewModel = new ViewModel();
$storage = Product\Storage::factory($this->getDb());
$productList = new Product($storage);
$data = $productList->loadProduct();
$arr = array();
if ($data) {
foreach ($data as $val) {
array_push($arr, $val);
}
}
print_r('teaaat'.$arr);
$viewModel->setVariables(array('productList' => $arr))
->setTerminal(true);
return $viewModel;
}
If I open print_r in the view,it show error Warning: Invalid argument supplied for foreach() in.... I think it cause of view can't call the controller.
Help me please,thanks.

Firstly when you try to use print_r it is expecting an array. So it should be something like print_r($arr). Also give this a try and see if it helps.
public function loadProductAction() {
$storage = Product\Storage::factory($this->getDb());
$productList = new Product($storage);
$data = $productList->loadProduct();
$arr = array();
if (is_array($data) && !empty($data)) {
foreach ($data as $val) {
array_push($arr, $val);
}
} else {
echo '$data is not an array or it is empty';
}
print_r($arr);
return new ViewModel(array(
'productList' => $arr
));
}
