Magento call a .phtml file in template with product collection

Question

I can call a .phtml file to my .phtml template like a list.phtml.

<?php 
  echo $this->getLayout()->createBlock('core/template')->setTemplate('goodtest/test.phtml')->toHtml();
?>

But in test.phtml i cannot call $_product values.

For example:

<?php 
$_productCollection=$this->getLoadedProductCollection();
foreach ($_productCollection as $_product): 
?>

works

<?php echo $_product->getName() ?>

not works:

<?php 
      echo $this->getLayout()->createBlock('core/template')->setTemplate('goodtest/test.phtml')->toHtml();
    ?>

In the file: test.html: <?php echo $_product->getName() ?>.

Do I must load full collection in product again in each included file, how can i get $_product values in test.phtml most effective way?

Answer 1

There are two options:

1. You can load product by Mage::getModel('catalog/product')->load(<product_id>) with id each time within foreach loop.

2. Use below

echo $this->getLayout()->createBlock('catalog/product_list')->setTemplate('goodtest/test.phtml')->toHtml();

instead of

echo $this->getLayout()->createBlock('core/template')->setTemplate('goodtest/test.phtml')->toHtml();

Answer 2

You can assign template through controller like @example

$this->loadLayout();
$listBlock = $this->getLayout()->createBlock('catalog/product_list')
            ->setTemplate('catalog/product/list.phtml')
            ->setCollection($collection);

    $this->getLayout()->getBlock('content')->append($listBlock);
    $this->renderLayout();
