如何在控制器symfony 2中渲染树枝宏

Question

i can't figure out, how to render a macro in Symfony 2 controller. This is how i can render a twig template

$this
  ->get("twig")
  ->render("AcmeBundle:Product:table.html.twig", array(
    "product" => $product
  ))
;

So i searching for something similar, but for rendering a twig macro. Thx for any suggestions!

Answer 1

Twig macro's are something inside a template. They are run whenever you render a template executing the macro.

Answer 2

Just create another "wraper" template, which would have only that macro in it. Something like

macro.html.twig file

{% macro sample(item) %}
   {# some code here #}
{% endmacro sample #}

sample_macro_wrapper.html.twig

{% from 'macro.html.twig' import sample %}
{{ sample(item) }}

controller.php

public function someAction()
{
      // ...........
      $renderedMacro = $this->get('twig')
           ->render('sample_macro_wrapper.html.twig', ['item' => $item]);
}
