Member username sequence

I am developing a client’s site whereby they have a list of users that already have a specific ID. What I was therefore hoping to do is when they register on the site they would use that ID for their username and sign up that way. If they entered an incorrect sequence for their username then they would not be allowed to register for the site.

This doesn’t have to be their username but it would have to be a field in the registration form in order for them to gain access to the site.

Is this possible with s2member?

Thank you for your inquiry.

Currently s2Member does not offer this functionality. However, with s2Member Pro you could protect your Free Registration/Paid Registrations Forms by putting your forms on a Password-protected page, or by using s2Member’s Shortcode/PHP Conditionals (or your own).

See: Dashboard -› s2Member® -› API / Scripting -› Advanced PHP Conditionals

With this you can protect your registration however you need to.
