将参数传递到Symfony2中的树枝视图

Question

I have a twig page which I included a picture , this picture will be loaded from a folder ( uploads ) , but the name ( example.jpg ) is loaded from the database :

<img src="{{ asset('uploads/example1.jpg') }}">

this works for me , but I want now that example1.jpg will be passed to the twig page :

return $this->render('MyAppExampleBundle:Default:index.html.twig', array(
            'logo' => $logo)); //$logo = 'example1.jpg'

How I can do this?

I have tried <img src="{{ asset('uploads/{{logo}}') }}"> but this is illogic and doesn't work .

Any help plz

Answer 1

What about,

<img src="{{ asset('uploads/' ~ logo) }}"> 

{{ ... }} twig delimiters can't be nested. You should then use concatenation.

Answer 2

尝试{{ asset('uploads/' ~ logo) }}
