New in version 1.11: The template_from_string function was added in Twig 1.11.
The template_from_string function loads a template from a string:
{{ include(template_from_string("Hello {{ name }}")) }}
{{ include(template_from_string(page.template)) }}
Note
The template_from_string function is not available by default. You must add the Twig_Extension_StringLoader extension explicitly when creating your Twig environment:
$twig = new Twig_Environment(...);
$twig->addExtension(new Twig_Extension_StringLoader());
Note
Even if you will probably always use the template_from_string function with the include function, you can use it with any tag or function that takes a template as an argument (like the embed or extends tags).
