BuddyPress.org

Hello!

I would like to restrict the registration on my site to only a specific email domain, and only if the member type is X.
My registration form includes the basic name/email/password fields as well as the buddypress base group fields, where the user can choose the member type (set up with plugin BuddyPress Xprofile Member Type Field).

Browsing around I found the following code to validate the email domain:

   function is_valid_email_domain($login, $email, $errors ){
 $valid_email_domains = array("gmail.com","yahoo.com");// whitelist email domain lists
 $valid = false;
 foreach( $valid_email_domains as $d ){
 $d_length = strlen( $d );
 $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
 if( $current_email_domain == strtolower($d) ){
 $valid = true;
 break;
 }
 }
 // if invalid, return error message
 if( $valid === false ){
 $errors->add('domain_whitelist_error',__( '<strong>ERROR</strong>: you can only register using @gmail.com or @yahoo.com emails' ));
 }
}
add_action('register_post', 'is_valid_email_domain',10,3 );

1) I tried replacing $valid_email_domains = array("gmail.com","yahoo.com"); with $valid_email_domains = (".edu"); but it didn’t work – I guess I should add a variable before it, to precise anything.edu as a valid domain? In a function, what would be the way to pass the “anything” argument? (I apologize if I don’t use the proper terms)
Would it be “” ?

2) I’ve tried checking how I could add one more validation argument, but I’m a bit lost.
After checking around and in the register.php, I guess I should use something like :

$membertype = $_POST ( 'type' => 'recruiter' )
 foreach( $membertype as $membertype ) {

So, perhaps something like

function is_valid_email_domain($login, $email, $membertype, $errors ){
 $membertype = $_POST ( 'type' => 'recruiter' )
 foreach( $membertype as $membertype ) {
I don't know what to put here - how to link both arguments "if member type is "recruiter" and if email domain belong to the whitelist then proceed, if not give an error message"
    $valid_email_domains = (""".edu");// whitelist
    $valid = false;
    foreach( $valid_email_domains as $d ){
	    $d_length = strlen( $d );
        $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
        if( $current_email_domain == strtolower($d) ){
            $valid = true;
            break;
        }
    }
    // if invalid, return error
    if( $valid === false ){
        $errors->add('domain_whitelist_error',__( '<strong>ERROR</strong>: you can only register using your .edu email address' ));
    }
}

add_action('register_post', 'is_valid_email_domain',10,3 );

I’m probably completely wrong, I don’t know how to code, I’ve just tried putting several things I found together..but if someone has an idea on how I could make it work I would be very grateful
