I'm searching how to make First Name and Last name fields required when we add a new user. Right now only username and Email fields are required.

I found a way by adding class="form-required" for the first and last name fields on the file user-new.php.

But I'm looking for a method with adding code on function.php and not touch to the WordPress Core.

Thanks.

If you were looking to make the fields required in the Wordpress admin form for adding new user as i understood from your question, where the output is not filterable, you could basically do what you described (adding form-required) on browser side

function se372358_add_required_to_first_name_last_name(string $type) {

    if ( 'add-new-user' === $type ) {
        ?>
        <script type="text/javascript">
        jQuery(function($) {
            $('#first_name, #last_name')
                .parents('tr')
                .addClass('form-required')
                .find('label')
                .append(' <span class="description"><?php _e( '(required)' ); ?></span>');
        });
        </script>
        <?php
    }

    return $type;
}

add_action('user_new_form', 'se372358_add_required_to_first_name_last_name');

Edit

In order to achieve the same on edit, you could use code like this:

function se372358_add_required_to_first_name_last_name_alternative() {
    ?>
    <script type="text/javascript">
    jQuery(function($) {
        $('#createuser, #your-profile')
            .find('#first_name, #last_name')
            .parents('tr')
            .addClass('form-required')
            .find('label')
            .append(' <span class="description"><?php _e( '(required)' ); ?></span>');
    });
    </script>
    <?php
}

add_action('admin_print_scripts', 'se372358_add_required_to_first_name_last_name_alternative', 20);

function se372358_validate_first_name_last_name(WP_Error &$errors) {

    if (!isset($_POST['first_name']) || empty($_POST['first_name'])) {
        $errors->add( 'empty_first_name', __( '<strong>Error</strong>: Please enter first name.' ), array( 'form-field' => 'first_name' ) );
    }

    if (!isset($_POST['last_name']) || empty($_POST['last_name'])) {
        $errors->add( 'empty_last_name', __( '<strong>Error</strong>: Please enter last name.' ), array( 'form-field' => 'last_name' ) );
    }
    return $errors;
}

add_action( 'user_profile_update_errors', 'se372358_validate_first_name_last_name' );

  • Thanks! That is almost what i need. Is it possible to make also the 2 fields (first and last name) required on profile.php and user-edit.php page on the backoffice with your method?

  • Thanks. It works! one last question : on the original answer you speak about output not filterable what do you mean please?

  • It's only that it would be more convenient to add these form-required to the html directly, instead of adding them by javascript. But since the form does not have a filter, that you could use to modify the output, one has to do it like this.

You can achieve this without modifying the core files in WordPress, but for the sake of the same you have to override entire user-new.php file via load-$pagenow hook present in wp-admin.php file.

Try the following.

  1. Create a folder named core-template inside your currently active theme. Create a file user-new.php inside that directory.

  2. Paste following code to that file

<?php
/**
 * New User Administration Screen.
 *
 * @package WordPress
 * @subpackage Administration
 */

/** WordPress Administration Bootstrap */
require_once( trailingslashit( ABSPATH ) . 'wp-admin/admin.php' );

if ( is_multisite() ) {
    if ( ! current_user_can( 'create_users' ) && ! current_user_can( 'promote_users' ) ) {
        wp_die(
            '<h1>' . __( 'You need a higher level of permission.' ) . '</h1>' .
            '<p>' . __( 'Sorry, you are not allowed to add users to this network.' ) . '</p>',
            403
        );
    }
} elseif ( ! current_user_can( 'create_users' ) ) {
    wp_die(
        '<h1>' . __( 'You need a higher level of permission.' ) . '</h1>' .
        '<p>' . __( 'Sorry, you are not allowed to create users.' ) . '</p>',
        403
    );
}

if ( is_multisite() ) {
    add_filter( 'wpmu_signup_user_notification_email', 'admin_created_user_email' );
}

if ( isset( $_REQUEST['action'] ) && 'adduser' == $_REQUEST['action'] ) {
    check_admin_referer( 'add-user', '_wpnonce_add-user' );

    $user_details = null;
    $user_email   = wp_unslash( $_REQUEST['email'] );
    if ( false !== strpos( $user_email, '@' ) ) {
        $user_details = get_user_by( 'email', $user_email );
    } else {
        if ( current_user_can( 'manage_network_users' ) ) {
            $user_details = get_user_by( 'login', $user_email );
        } else {
            wp_redirect( add_query_arg( array( 'update' => 'enter_email' ), 'user-new.php' ) );
            die();
        }

Note that this is the same code as user-new.php, but now you have the control of what needs to be changed in that file.

  1. Now, you need to tell wordpress to load that file instead of its core user-new.php, create following function in functions.php of your theme.
function se_372358_user_new_template() {
    require_once( get_stylesheet_directory() . '/core-template/user-new.php' );
    die();
}
add_action( 'load-user-new.php', 'se_372358_user_new_template' );

You should now be able to see your new template being loaded.

WordPress Codex Says:

The following example demonstrates how to add a "First Name" field to the registration form as a required field. First Name is one of WordPress's built-in user meta types, but you can define any field or custom user meta you want. Just keep in mind that if you create custom user meta, you may need to create additional admin UI as well.


//1. Add a new form element...
add_action( 'register_form', 'myplugin_register_form' );
function myplugin_register_form() {

    $first_name = ( ! empty( $_POST['first_name'] ) ) ? sanitize_text_field( $_POST['first_name'] ) : '';
        
        ?>
        <p>
            <label for="first_name"><?php _e( 'First Name', 'mydomain' ) ?><br />
                <input type="text" name="first_name" id="first_name" class="input" value="<?php echo esc_attr(  $first_name  ); ?>" size="25" /></label>
        </p>
        <?php
    }

    //2. Add validation. In this case, we make sure first_name is required.
    add_filter( 'registration_errors', 'myplugin_registration_errors', 10, 3 );
    function myplugin_registration_errors( $errors, $sanitized_user_login, $user_email ) {
        
        if ( empty( $_POST['first_name'] ) || ! empty( $_POST['first_name'] ) && trim( $_POST['first_name'] ) == '' ) {
        $errors->add( 'first_name_error', sprintf('<strong>%s</strong>: %s',__( 'ERROR', 'mydomain' ),__( 'You must include a first name.', 'mydomain' ) ) );

        }

        return $errors;
    }

    //3. Finally, save our extra registration user meta.
    add_action( 'user_register', 'myplugin_user_register' );
    function myplugin_user_register( $user_id ) {
        if ( ! empty( $_POST['first_name'] ) ) {
            update_user_meta( $user_id, 'first_name', sanitize_text_field( $_POST['first_name'] ) );
        }
    }

this code can be added to functions.php file,

further info could be found on Wordpress codex
