I created a new content type in Drupal 7 and I want to make a template to customize the node add page for that content type. I want to be able to check if the user is authenticated with Facebook before they can use the node add form. If user is not authenticated then I will show them a paragraph explaining that they need to authenticate via facebook before they can use this form. I want them to always see the form link but they can only use the form if they are authenticated to facebook. I just don't know where to put it. Is it possible to make a template file specifically for that node add page so that I can include my logic?
