Restrict registrations to one domain

This hack restricts new registratiosn to users who have eMail-Adresses from one specific domain.
This can be useful if you are running a corporate/internal forum.

In register.php FIND

PHP Code:

// check for missing fields 

ABOVE that ADD

PHP Code:

// Check for vaild eMail domain
if (!preg_match('/@mydomain\.com$/', $_POST['email'])) {
  eval('$errors[30] = "' . fetch_phrase('bademail', PHRASETYPEID_ERROR) . '";');
} 

Note: mydomain.com must be replaced with the restricted domain of course

Should work with all vB 3 versions.

Thanks so much! It works perfectly.

Thanks for the great hack, Kirby ... I'm sure it will be very useful

At an educational institution, student and staff e-mails are often located on a different machine so that:

a staff e-mail address is staff@school.edu
a student e-mail address is student@student.school.edu

How would one alter your hack to permit both staff and student e-mail addresses to register?

Nice hack

In order to ensure security, the change email should also be restricted. Are there any other loopholes?

Well, preventing Users from changing their eMail after registration was never a planned Feature for this.
So it is working as designed

Thanks for this-- we're running a 3.5.4 system. Do you think it will still work?

Also, like fms, we have two domains we need to allow. Is it possible that wild card symbols would work, like www.pdq*.* for two domains (www.pdqstudents.edu and www.pdqparents.org).

This is kind of a "huge deal" to us, because we want a facebook.com type of limited registration access.

Thanks again!

Actually, this would be a handy addition for my site , though i want to restrict them from using my sites e-mail address.

I give all new members an e-mail address, and i want to avoid them using username@mydomain.com as their e-mail address and then logging into the mail on the site and getting the authrosiation email.

Just removing the ! should do that for me - thanks for this.

Okay, I made the change to our 3.5.4 system, and it does not seem to work. New users (with non-approved email domains) simply get approved with no bademail message. Any ideas for making it work with 3.5.4?

I also heard there was a hack to change the banned email list from a blacklist to a whitelist. This would work even better for us, since we have two domains we want open. Anyone recall the hack for this?

Thanks again!
