Question

I have created two functions in controller of Symfony as follow:

first is newAction

public function newAction()
{
    return $this->render('AcmeTaskBundle:Default:index.html.twig');
}

then subAction

public function subAction()
{
    echo "hello";
}

I want to use some data from index.html.twig into subAction function.

How I can do that?

Answer 1

All you need is to use

$content = $this->renderView('AcmeTaskBundle:Default:index.html.twig')

This will render contents of template in variable

http://symfony.com/doc/current/book/controller.html#rendering-templates

EDIT according to comment

If you need to render only part of template – then you should refactor your templates.

Exclude that part of code from your index.html.twig into separate template file and include it in index.html.twig:

...
{% include 'AcmeTaskBundle:Default:subpage.html.twig' %}
...

And then in your subAction() call:

    $content = $this->renderView('AcmeTaskBundle:Default:subpage.html.twig')
