Emails can not be used as user names as wordpress uses user names by default as part of urls (for example the author page). Therefor it is not enough to let users register with email addresses, you also need to have some code to handler the URL related issues. Anyway this sounds like an XY … Read more
Answer originally posted on another question which was more “why we can’t” instead of “how”: https://web.archive.org/web/20210408084000/https://wordpress.stackexchange.com/questions/135304/why-cant-i-update-username-through-wordpress-api/386265 Here is the solution I used to change the username properly (based on https://www.wpbeginner.com/wp-tutorials/how-to-change-your-wordpress-username/ which had missing information): I was able to change the username simply with SQL using update wp_users set user_login = “old_username”, user_nicename = “new_username” where … Read more
In the en_GB version of the .mo translation file, this string is available: <strong>ERROR</strong>: Invalid username. <a href=\”%s\” title=\”Password Lost and Found\”>Lost your password</a>? and the reference is from wp-includes/user.php on line 93. 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
You have an errors in $items.= //Change Password, Logout, etc and $items.= //Sign up, Lost Password you haven`t value for assign.Set something into $items variable or delete this strings and all will work.
One alternative is to modify the $_POST[‘user_login’] input value when submitting new registration form, that is before WP process the registration form. A good hook to achieve this is login_form_register that fires before processing and rendering registration form. login_init also works but need more work to make sure we are on register action. add_action(‘login_form_register’, ‘custom_user_login’); … 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/
