Twig - 渲染变量

Question

I am rendering a template file, in which I have a variable {{page_content|raw}}. This all works fine. However I want to render that variable as twig... the value contents more variables in which I want to parse using the same environment.

I am using PHP.

You could use the template_from_string function.

See the documentation here and here. You need to scroll a bit down in the second link to Twig_Loader_String. Direct link to this loader

Twig_Loader_String loads templates from strings. It's a dummy loader as the template reference is the template source code

It seems to be necessary to explicitly say you want to use it as seen in the first link:

$twig = new Twig_Environment(...);
$twig->addExtension(new Twig_Extension_StringLoader());

Also possible directly in your twig template (first link)

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