JFBConnect login under condition

JFBConnect doesn't have any way built-in to do that. There are options to respect the Joomla activation settings, so if email or admin approval is required, the user's account won't be useable until those steps are taken.

There are a few ways I can imagine you could implement what you want by creating a profile plugin. With that, you could add a "Code" button on Facebook registration page that would be checked during account creation. Without that, the account will be 'blocked' in Joomla and the user won't be able to get in. That wouldn't take too much work, but you may need a PHP developer to help implement it.

Before we go down that road though, can you tell me how you're preventing users from registering through Joomla? If you already have a system, that may be able to work with JFBConnect as well.

Hope that helps give some ideas or get you started.

Thanks,

Yiannis,
With JFBConnect, it wouldn't be too difficult. We have a setting for "Registration Mode" which can be set to 'Normal'. That will allow you to ask have a mini-registration form where the user could select their username, password and email address. Those fields can still be automatically generated and hidden though. Then, with a social profile plugin, you could add a new field for "Registration Code" that would be checked to activate the user or not.

With that combination, you'd have everything automatically generated, except, there would be a 1-field form the user would have to enter the proper code in.

Please note that the Social Profile plugins I'm mentioning are specific to JFBConnect. They are not the "User - Profile" plugin that is a part of Joomla, which is a lot more limited in what it can do I believe. That may be an option, and JFBConnect does work with the User - Profile plugins, I'm just not as familiar with developing them.

I hope that helps,
Alex
