A variable inside an asset declaration in Twig

Question

My inline style looks like:

style="background-image: url({{ asset('bundles/testblog/images/id.jpg') }});"

the part id of the url must change depending on a varibale. How can I make this happen inside the asset.

I tried :

style="background-image: url({{ asset('bundles/testblog/images/'{{variable}}'.jpg') }});" 

But to no avail.

Answer 1

Use ~ for concatenation,

style="background-image: url({{ asset('bundles/testblog/images/' ~ variable ~ '.jpg') }});"

Also,

You don’t need to nest {{ ... }} delimiters. The ones you used to wrap asset() call are also used to print any other variable they contain.

Answer 2

style="background-image: url({{ asset('bundles/testblog/images/' ~ variable ~ '.jpg') }});"
