    How to assign a UserName value at creation

    matteradmin9PV0评论

    I want to allow users to register on my site. However, I want to assign the UserName value so that it is in a particular format and so that the user cannot change it. The format will incorporate the UserID value along with a prefix, therefore I do not need to see if the UserName is already being used because this value should be unique.

    Can this be accomplished with a filter and corresponding action?

    Thanks in advance.
