How to render TWIG output to a variable for later use (symfony2)?

Question

Instead of doing this rendering of each slide in my TWIG like this (see line 6):

{# loop out the slides #}
{% for c in contents %}
    {% set i=i+1 %} {# increas         


        

Answer 1

You can get content form rendered object like this:

$this->render('BizTVArchiveBundle:ContentTemplate:Some.html.twig', array())->getContent();
