This is the desired code

<img src="{{ asset.getUrl('newsImageHalfWidth') }}">

Which works. However I want the transform name to be replaced by the contents of


So in a kind of pseudocode it would be

<img src="{{ asset.getUrl('{{entry.newsImageSize}}') }}">

which of course does not work.

With Twig, you'll never need to nest tags within other tags. In fact, it's impossible to do.

You can simply pass your variable into getUrl instead of using a string.

<img src="{{ asset.getUrl(entry.newsImageSize) }}">
  • Thanks. I've tried that and I get a 'Division by zero' error. But when I just use {{ entry.newsImageSize }} I get the transform name displaying on the page. So can't work out what I am doing wrong. Feb 17, 2015 at 0:44
  • I'm getting closer. I think the reason the code is not working for me is because entry.newsImageSize is from a dropdown field, and is therefore not a string. I'm now looking for a way to convert the variable to a string. Feb 17, 2015 at 1:14
  • If you've got devMode enabled, try using {{ dump() }} to figure out exactly what that value holds. You may also want to setup a conditional, to ensure that entry.newsImageSize is not empty before trying to use it.

  • Thanks for your help Lindsay D. The variable was not empty, but the wrong type, so when I converted to a string using <img src="{{ asset.getUrl( "" ~ entry.newsImageSize) }}"> it all worked OK. There might be a more elegant way to do the conversion. Feb 17, 2015 at 1:22
  • Check out the the dropdown fields docs... That may help you find a more elegant solution.
