如何在树枝模板中显示Controller数组

Question

product.html.twig:

<ul id="navigation">                 
    <li>
        <a href="<?php echo product.getId() ?>">
            <?php echo product.getDescription() ?>
        </a>
    </li>
</ul>

Controller Action method contains:

public function showAction($id = 5)
{
    $product = $this->getDoctrine()
        ->getRepository('AppBundle:Product')
        ->find($id);

    if (!$product) {
        throw $this->createNotFoundException(
            'No product found for id '.$id
        );
    }
    else 
    {
        return $this->render('default/productItem.html.twig', array(
            'id'=> $id,
            'name' => $name));
    }
}

I cant see the output in the list

You should use the Twig syntax.

<ul id="navigation">                 
    <li>
        <a href="/page.php?id={{ product.getId() }}">
            {{ product.getDescription() }}
        </a>
    </li>
</ul>

In your case your input have to be an object. With the functions getId() and getDescription().

In your code you can remove "get" and write only {{ product.id }} for example.
