title: How can i have a link field in a content type display a default text when the field is empty
body: <p>How can i have a link field in a content type display a default text when the field is empty.</p>
  
  <p>For now i have a field as a link - and the link is set to have a static title. This Works fine. </p>
  
  <p>But i'd like to display a default title if the field is empty with no link (but still rendered as a link/button).</p>
  
  <p>It's not a view - so i can't use "rewrite output if empty".</p>
  
  <p>I'm a newbee to drupal - so please help </p>
  
  <p>This shows what I've got so far:

  <p>When the link field is empty the button doesn't show. Instead of not showing when empty I'd like it to show someting like this as default:
  <a href="http://1fb72c32b5e90467b795f388746f7501b3ad8021.web9.temporaryurl.org/tmp/link3.PNG" rel="nofollow">http://1fb72c32b5e90467b795f388746f7501b3ad8021.web9.temporaryurl.org/tmp/link3.PNG</a> (the button "Bestil på tlf...") </p>
