I found this using Poedit and searching using Ctrl + F. From line 93 we get the following code: return new WP_Error( … Read more
Try putting this in your functions.php function wpse60605_change_username_label( $defaults ){ $defaults[‘label_username’] = __( ‘Username or Email’ ); return $defaults; } add_filter( ‘login_form_defaults’, ‘wpse60605_change_username_label’ );
Just add a meta record that tracks the state of the username-changing actions: $user = wp_get_current_user(); $did_one_change = get_user_meta($user->ID, ‘changed_username’, true); if($did_one_change !== false) wp_die(‘You already changed your user name once!’); wp_update_user(array( ‘ID’ => $user->ID, ‘first_name’ => $_POST[‘first_name’], ‘last_name’ => $_POST[‘last_name’], )); // here add a meta entry that suggests the user has changed their … Read more

I think you can make this much easier than you are. Just create a my-projects page and forget about the custom rewrite. Why? Because a user will only need to see their own projects. No need for a just rewrite because you can get the current user any time. Embed the project rendering into a … Read more
There are ways to trick WP into pre-populating the username field, but I’m pretty sure it would involve using POST and also tricking it into thinking there were errors in a previous submission. My advice would be to just use Javascript (or jQuery, as I’ve done below). It’s still ‘hacky’, but at least it gets … Read more
Yes there are plugins that do this, for example, http://wordpress.org/extend/plugins/restrict-usernames/
If you want this for all future users then hook into the user_register event and update it there. Pull the WP_User using get_userdata and wp_update_user info with the new display name. add_action( ‘user_register’, ‘wpse_20160110_user_register’, 10, 1 ); function wpse_20160110_user_register ( $user_id ) { // get the user data $user_info = get_userdata( $user_id ); // pick … Read more
I think the answer is in the source. $username = wp_strip_all_tags( $username ); $username = remove_accents( $username ); // Kill octets $username = preg_replace( ‘|%([a-fA-F0-9][a-fA-F0-9])|’, ”, $username ); $username = preg_replace( ‘/&.+?;/’, ”, $username ); // Kill entities // If strict, reduce to ASCII for max portability. if ( $strict ) $username = preg_replace( ‘|[^a-z0-9 … Read more
