Hello! I am pretty much a noob in WordPress and PHP, but a quick learner.
My blog consists of movie reviews. I want to add a custom field to each post in order to provide an IMDb link for the movie page. This link will be used in a sidebar, on the post page. How can I do this and what files must I modify? I searched on the forum for this sort of issue but found nothing. Sorry if it has been answered before. Thank you!
