Make Twig syntax from string be parsed

Question

I stored a format of shopping order in database, it's like #{{ number }} (it's just a string), how can use this {{ number }} as a execution of Twig.

For example, in my Controller, when I render the view, I also pass a $number variable:

return $this->render('MyBundle:View:index.html.twig', array('number' => 123));

and in my index.html.twig file, it's something like

{% set orderFormat = some_function_to_get_order_format() %} 
// orderFormat will be #{{ number }}
// What can I do to print orderFormat to #123

Try template_from_string function.

{{ include(template_from_string("Hello {{ name }}") }}

The function "template_from_string" does not exist.. What happened? I used Symfony 2.3 – Tuan nguyen Jul 25 '13 at 07:09
check that you have Twig 1.11 or more. – Alexey B. Jul 25 '13 at 08:01
A little late, but you have also to enable StringLoader extension. Consider reading http://stackoverflow.com/questions/19478219/activate-stringloader-twig-extension-in-symfony – Patrick Jun 29 '15 at 06:58
