registration_errors filter hook not working

I need a custom user field that is available during registration but not available when a user edits their profile. So I added it the regular WordPress way and not as an s2Member extra field. I’ve also added some validation using WordPress’ registration_errors filter hook which works in a regular copy of WordPress. However when s2Member is active it overrides the normal WordPress login screen and seems to do it’s own error checking, ignoring anything I’ve added through the registration_errors filter hook.

How do I add registration form validation for a custom field not created using s2Member?

Is there a way to prevent s2Member overriding the registration form so I can use the regular WordPress registration form, but still include any fields created using s2Member? This would be my preference.

Chris, you can have s2 profile fields that show up during registration only and not the profile page. In the settings for the field, you’ll see one labelled “Allow Profile Edits”.
