 * In my template file i’ve got a custom file upload field. I want it to display
   for example, ‘Download PDF’ where PDF is the actual file extension.
 * It won’t just be PDF files so i can’t just put that. I need some php that is 
   going to show the file extension.
 * I’ve found this but i’m unsure how to use it.
