Using array values as keys in another array

[Sprocket]

I'm passing two arrays to my twig template, effectively this:

$categories = array( '1'=>'fruit', '2'=>'cars'); $products = array( array('name' => 'apple', 'category'=>'1') );

How do I get twig to echo the appropriate value for the category that the products belongs? I was hoping something like this:

{% for product in products %} {{ categories[product.category] }} {% endfor %}

I appreciate this isn't perhaps the best place to post this but everything I've found elsewhere is confused and there doesn't seem to be another Twig forum. Thanks for your time.

You should use the mailing-list for your questions (https://groups.google.com/group/twig-users).

I've just tried your example and indeed, it works as expected. Here is how I've passed the variables to the template:

echo $template->render(array(
    'categories' => array('1'=>'fruit', '2'=>'cars'),
    'products' => array(array('name' => 'apple', 'category'=>'1')),
));

Thanks, I will use the mailing list. I'm using the FuelPHP parser so that may be complicating things. Thanks again.
