Symfony and Twig, prerender, parse view, replace content

Question

I need replace some content in every file of view. But content in many places is just a text, not a variable, co i cant use variable|replace() filter.

Is there any way to get view (eg in Controller) content before displaying so I can pass it to some function and return ready to display content? Or maybe there is way for replace all content in block tag?

Answer 1

Symfony controller has 2 functions render() and renderView() , the former renders a view and returns a Response , the latter just renders the view and returns the string result.

so you could in your action:

$content = $this->renderView('my-view.html.twig', [...]);

$content = str_replace('my text', 'my new text', $content);

return new Response($content);
