I want to make my single wordpress installation a closed community. Only people who know the registration key should be able to sign up. I already added some more fields to the registration form but I can't fin a simple solution for the registration form to check if the code is correct!?

Looking forward for some ideas! Thank you!

Here's what I do have until now:

// This function shows the form fiend on registration page
add_action('register_form','show_first_name_field');

// This is a check to see if you want to make a field required
add_action('register_post','check_fields',10,3);

// This inserts the data
add_action('user_register', 'register_extra_fields');

// This is the forms The Two forms that will be added to the wp register page
function show_first_name_field(){
?

You are saying that this is for an university broadcasting station. So I would assume everyone involved has an @univeristy.edu email address. If not, I'm still posting this (even if it's a late reply) because it can be a good alternative solution for people who are in a similar situation.

So this could be too restrictive or not for your use case, but you could only authorize people with valid email domain to register.

From this answer

add_filter( 'registration_errors', 'my_authorized_domains', 10, 3 );
function my_authorized_domains( $errors, $sanitized_user_login, $user_email ) {

  if (! preg_match('/( |^)[^ ]+@university\.edu( |$)/', $user_email )) {
    $errors->add( 'invalid_email', __( 'ERROR: Only valid "university" email address is allowed.' ));
    $user_email = '';
  }

  return $errors;
}

Registration will fail if email address is not from authorized domain and removes the need for sharing an authorization key, but the caveat is that their email address should be issued from a predictable domain.

But then again, adding an extra check (or modifying to check against the shared registration key) wouldn't be too hard using the above function

You could use plugin Pie Register for the invitation codes or have look at this snippet ( Creating a Closed Wordpress Community Using Referral Codes ). This forum post could be useful too.
