Lets say I have image fields in my node. When I get that fields values in the twig it returns the image URL without any issue.


But now I want to add a specific parameter (lets say ?param=0) to the end of that link. Without hard coding the parameter in the twig file is there a way to write a hook that adds that parameter for all the image links in every node. So if I have to change the param I only need to change it from one place.

  • How is the image link created ? is it another field ? Link to itself as a bigger image ? – GiorgosK Mar 5 '19 at 8:46
  • @GiorgosK No this is an normal image field in the node. I want to know how to add a param without putting it like file_url(node.field_image.entity.uri.value)?param=0. Is there a way to do this like globally. If I change from one place it should apply to all the images. – i am batman Mar 5 '19 at 9:08

You can do this with a preprocess function THEMENAME_preprocess_field and check whether the field is an image and it has a URL

function THEMENAME_preprocess_field(&$variables) {
  if($variables["element"]["#field_type"] == "image"){
      $variables["items"][0]["content"]["#url"]->setOption('query', ['param' => '0']);
