Why were some WP users not migrated to PHPBB?

[benw]

There are several users that were not migrated. Why would this be?

Most of them have similar email addresses such as @163.com, @mail.ru, @gmx.com
However, some more ordinary names/emails were also not added.

Thanks

Migrated from phpBB to Wp?
In this case may due to usernames that contains not allowed chars into wordpress?

No I mean when migrated from WordPress into phpBB.

What is the criteria? Do the user details need to conform to the phpBB settings? For example, if the phpBB setting for minimum length of username is 5, then are WordPress users only migrated if the user_login has 5 or more characters? Or does the plugin insert the users into the database directly?

A few WordPress users do not have an email set - and the plugin did not migrate them to phpBB. I can understand that.

Thanks,

mh strange that are not added: yes they are added directly into db, no check is done about username length because it is assumed that if an username is too long, then the insert query should stop with an error. How phpBB is configured after about this, do not matter
If there are mismatching usernames/email also usernames are skipped and a warn should display for each, so that you can may adjust those with email problems (even if the integration run by email in effect, and users may can have mismatching username/email if the WP phpBB extension has been installed into phpBB)

Wait, are you saying that the username needs to be the same as the email address before migrating from WordPress to phpBB?

Many of the existing WordPress users have their email address as their username but I would prefer to use the WordPress "display_name". That would be a cool option your plugin could add - allow the selection of which field (user_login, user_email, or display_name) to use as the phpBB username when migrating.

Anyway, when I update the production website, I was planning to update the users in the WordPress database by altering the user_login to be the display_name, before migrating them to phpBB. That should work, right?

not required, because if mismatching, the script should inform you about problems, if an user is not transferred for example because a same username found, or email.
You can adjust these users email to match the same in phpBB, using the WP w3all tasks (also under tools menu)
The script has not been checked by long long time, may let know if something you note still seem not working as expected.
You can repeat the transfer process and check?
