I have a custom text field which I use to display some voucher code to users. I have it in a custom content type named (machine name) : 'add_deal'.
What I want to do is to style the field when the node is displayed and add a link/button next to that field to copy the text in that field.
I created a field--field-type--cotent-type.tpl.php file, but how do I use it, and I dont think its working for me either. Is there any hook function I need to use to make use of that tpl file?
How could I achieve it?
