WordPress 5.8 – Hide or Remove personal fields from admin Profile page

• This is working for me in 5.8.
• Works in “adding new user” and in “edit user”.
• “Public display name” managed with a plugin.

The code:

// Remove fields from Admin profile page
if ( ! function_exists( 'cor_remove_personal_options' ) ) {
    function cor_remove_personal_options( $subject ) {
        $subject = preg_replace('#<h2>'.__("Personal Options").'</h2>#s', '', $subject, 1); // Remove the "Personal Options" title
        $subject = preg_replace('#<tr class="user-rich-editing-wrap(.*?)</tr>#s', '', $subject, 1); // Remove the "Visual Editor" field
        $subject = preg_replace('#<tr class="user-comment-shortcuts-wrap(.*?)</tr>#s', '', $subject, 1); // Remove the "Keyboard Shortcuts" field
        $subject = preg_replace('#<tr class="show-admin-bar(.*?)</tr>#s', '', $subject, 1); // Remove the "Toolbar" field
        $subject = preg_replace('#<h2>'.__("Name").'</h2>#s', '', $subject, 1); // Remove the "Name" title
        // $subject = preg_replace('#<tr class="user-display-name-wrap(.*?)</tr>#s', '', $subject, 1); // "Display name publicly as" field (not working ok when editing user. Better remove and manage with "Force First and Last Name as Display Name" plugin
        $subject = preg_replace('#<h2>'.__("Contact Info").'</h2>#s', '', $subject, 1); // Remove the "Contact Info" title
        $subject = preg_replace('#<tr class="user-url-wrap(.*?)</tr>#s', '', $subject, 1); // Remove the "Website" field in EDIT USER
        $subject = preg_replace('#<th scope="row"><label for="url(.*?)</th>#s', '', $subject, 1); // Remove the "Website" field in NEW USER (part 1)
        $subject = preg_replace('#<td><input name="url"(.*?)</td>#s', '', $subject, 1); // Remove the "Website" field SUKINOZ in NEW USER (part 2)  
        $subject = preg_replace('#<h2>'.__("About Yourself").'</h2>#s', '', $subject, 1); // Remove the "About Yourself" title
        $subject = preg_replace('#<h2>'.__("About the user").'</h2>#s', '', $subject, 1); // Remove the "About the user" title      
        $subject = preg_replace('#<tr class="user-description-wrap(.*?)</tr>#s', '', $subject, 1); // Remove the "Biographical Info" field
        $subject = preg_replace('#<tr class="user-profile-picture(.*?)</tr>#s', '', $subject, 1); // Remove the "Profile Picture" field
        return $subject;
    }

    function cor_profile_subject_start() {
        if ( ! current_user_can('manage_options') ) {
            ob_start( 'cor_remove_personal_options' );
        }
    }

    function cor_profile_subject_end() {
        if ( ! current_user_can('manage_options') ) {
            ob_end_flush();
        }
    }
}
add_action( 'admin_head', 'cor_profile_subject_start' );
add_action( 'admin_footer', 'cor_profile_subject_end' );

//Remove fields from Admin profile page via JS to hide nickname field which is mandatory
function remove_personal_options(){
    if ( ! current_user_can('manage_options') ) { // 'update_core' may be more appropriate
        echo '<script type="text/javascript">jQuery(document).ready(function($) {
            $(\'form#your-profile tr.user-nickname-wrap\').hide(); // Hide the "nickname" field
        });</script>';
    }
}
add_action('admin_head','remove_personal_options');

// Removes ability to change Theme color for the users
remove_action( 'admin_color_scheme_picker', 'admin_color_scheme_picker' );
