Email as username issues

In the MP configuration I can set "Use Email as Username" = YES and MP will set the Joomla login name and email to the user email. The problem is users do change their emails from time to time.
In Custom Fields I set the email field to Show on Profile = NO and in Joomla Users configuration I set Change Username = YES. Now the user can change their email/username.
Two issues: 
1. The user can change their username to something that isn't a valid email.
2. The Joomla user email is never updated.

Is there a way to make sure the username is a valid email and can the Joomla user email be updated to match the Joomla username? I thought I could find a Joomla extension that provided this feature but I haven't found one.

Hello

Unfortunately, we do not have a way to handle this case yet. If users change their username from Joomla to be something else (not a valid email), we do not have a way to control it (yet). I will see if I can do something to prevent that in future releases, for now, it is not available

I did find a partial solution in another thread.
In Joomla Global Configuration >> Users >> Change Username = NO
In MP Custom Fields >> Email >> Show on Profile = YES, Can Edit On Profile = YES

Then when a user changes their email the username is updated. I moved the email to the top of the list which moved it below the username and password fields.

When the user presses UPDATE then the username is updated too.

Ah, Yes. I forgot Joomla has a setting to prevent changing username. Thanks for sharing the solution back to us

I have just come up against this exact same issue - thank you Hilmar for providing the solution!

I didn't understand the solution for a moment, but the key to it is that changing Joomla Global Configuration >> Users >> Change Username = NO makes the username field on the user profile edit page read only. If it is left as editable then the new email address does not overwrite the old email address in the username field.

I would never have worked this out for myself, so thank you.

Tuan - it would be a much better user experience in this scenario if the username was not displayed and the email address could be displayed just before the password instead. I know I can hide the username with css, but I can't move the email address before the password. I realise that would be tricky for you.

Hello Roger

Just want to be clear, the user profile page we are talking about here is the User Profile page from Membership Pro extension, correct? If so, Yes, I can handle this change in next release of the extension

Hi Tuan,

Yes, it is the User Profile page from Membership Pro extension.

I've just double checked the sign-up form and that already behaves exactly as I'd like the profile update page to behave - if you set "Use Email as Username" = YES then it replaces the username field with the email field. If that can be done on the user profile page too then that would be perfect.

See screenshots below of that section of my current sign up and user profile screens.
 
 

Thanks,
