This is probably a really stupid question that I should know the answer to but …
How do I link to another page/post on the same blog? Yes I know that I could write Bla but this mean that the link will stop working if I change domain (yep, it recently happened to me). How can I link in a way that is “domain independent”?
Oh… you want to write this inside a post. Sorry. No you can’t insert PHP using the editor.
Though I’ve never used them before I think I’d cook up a shortcode to do this if it were me. Maybe there is a default shortcode for the purpose. I’m not sure. At any rate, it should be a simple function to write.
