Members checking out will sometimes take the path of least resistance and use their email address as their username. That can cause confusion later, for example, if your site shows usernames anywhere members can see each other, like a member directory. This code recipe requires members to choose a username separate from their email address at checkout.

Use this recipe if you want to be sure members pick a real username instead of defaulting to their email address.

About the Code Recipe

This recipe hooks into the pmpro_registration_checks filter, the same checkout validation filter PMPro uses for other custom checks. It looks at the username a member submits and, if it contains an @ symbol, blocks checkout and shows an error asking them to choose a different username.
