Autogenerate or remove username
-
This excellent plugin allows members to log in with their email address and password. A username is no longer required.
How can I remove ‘username’ from the registration form?
I want to banish the concept of the username from my system entirely – I effin hate usernames, stupid anonymous usernames are the scourge of the internet, grrr!
On my network I want people to sign up with email address and full, real name, preferably with seperate fields for first and last name.
‘username’ is now a required field and “unrequiring” it probably messes up the system. Is there a way to autogenerate something behind the scenes? Generate it based on the real name?

This function for bp-custom.php adds fullname from xprofile field_1 to wp_usermeta.
function synchro_wp_usermeta($user_id, $password, $meta) {
global $bp, $wpdb;
$fullname = $meta[field_1];
$space = strpos( $fullname, ' ' );
if ( false === $space ) {
$firstname = $fullname;
$lastname = '';
} else {
$firstname = substr( $fullname, 0, $space );
$lastname = trim( substr( $fullname, $space, strlen($fullname) ) );
}
update_usermeta( $user_id, 'nickname', $fullname );
update_usermeta( $user_id, 'first_name', $firstname );
update_usermeta( $user_id, 'last_name', $lastname );
$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET display_name = %s WHERE ID = %d", $fullname, $user_id ) );
$wpdb->query( $wpdb->prepare( "UPDATE {$wpdb->users} SET user_url = %s WHERE ID = %d", bp_core_get_user_domain( $user_id ), $user_id ) );
}
add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);It shouldn’t be a big step to make the fullname lowercase, strip the spaces and store it as username.
Make lowercase and strip space looks something like this:
$str = strtolower($str);
$str = str_replace(' ', '', $str);But does the system even allow changing the username at the wpmu_activate_user stage?
The username is stored in four places in the database:
wp_signups -> user_login
wp_users -> user_login
wp_users -> user_nicename (?!)
wp_users -> user_url (as last part)
Manually changing the username at these points in the database does NOT screw up my system. Login with email address continues to work fine with the same password. The profile page and links function as normal.
That is good news. It means it is possible to simply update the username from this same function.
Now I just have to figure out the PHP and the queries for those four fields. Any pointers apprecriated!
EDIT: Is $user_id a number or the username? That could complicate things…
I assume $user_id is the username. Can I make this a two-stage rocket? First run the synchro_wp_usermeta function and then a separate function to deal with username, synchro_name_username? Put them in a plugin with something like this at the bottom?:
add_action( 'wpmu_activate_user', 'synchro_wp_usermeta', 10, 3);
add_action( 'wpmu_activate_user', 'synchro_name_username');Would that execute the functions in the right order?
To autogenerate a temporary username put this function in bp-custom.php:
function randomusername() {
$length = 10; //length of string
$start = 65; //Where to start from on ascii table
$end = 90; //where to end on the table
for ($k = 0; $k < $length; $k++){
$randomname .= strtolower(chr(round(rand($start, $end))));
}
return $randomname;
}Make this edit to the username input field on the form (hacking core file, should become easier in version 1.1):
<input name="user_name" type="text" id="user_name" value="'.$user_name = randomusername().'" maxlength="50" />Test it if you want; you’ll see a random string in the username field that will be replace by the autogenerated username based on fullname on activation.
You can hide the username field on the signup form, without getting error messages for not giving it proper TLC, by using this CSS trick.
That requires another core file hack, since you need to add a id like username-form-field. Again, should become easier in version 1.1.
My registration form is now:
Name:
Email address:
And that’s it! Everything works. Full name is available as first and/or last name. The URL is the full name lower case without spaces.
Only thing left to do is clean up the email messages etc. that still mention the username…
