Redirect to referring page from login page after successful login

Hi Ibrahim,
I didn’t quite get what you’re trying to accomplish.
Can you be more clear?

Sorry for that.

Some of my contents, say only posts, are restricted by the UM plugin. For logged out users, the post only show a message. In that message I have provided the link to the login page (created by the UM plugin).

After logging in, will it be possible for the user to be redirected to the original post’s link, they first ended up?

For example, https://roadtouk.com/working-in-acute-medicine/

Clicking “Login” takes you to the login page. And upon logging in, UM lets me choose among four things:
1. Refresh the page (Which just refreshes the login page)
2. Redirect to another pre-specified URL.
3. Redirect to their profile
4. Redirect to the admin.

I want them to redirect to the previous page.

You can do something like this below. This will redirect the page to the referrer after a successfull login. I am not sure how well this will work as this is before the Ultimate Member re direct.

I would create a custom Role and do not redirect that Role anywhere on login. I beleive their is an option to redirect to referred based on the role. I am not sure though.

<?php
add_action( 'um_on_login_before_redirect', 'my_on_login_before_redirect', 10, 1 );
function my_on_login_before_redirect( $user_id ) {
    // your code here
	wp_safe_redirect( wp_get_referer() );
}
?>
