Thanks, John. I understand conceptually what I need to do. I’m looking for instructions on how to do it, if possible.
Scenario:
1. Bill is on the page https://www.helpmeout.com/post-1
2. Bill clicks “Log-In.”
3. Bill logs in with FB credentials using wp-login.
4. Bill is logged in and taken back to post-1.
How do I pass the current url in step 2, and then how do I set that dynamic value in Redirection in step 4?
