Disable WordPress Admin Bar for All Users Except Admins

Solution to Hide Admin Bar for Non-Administrators

Custom Code Solution

Add this code to your theme's functions.php file or in a site-specific plugin:

This code checks if the current user is not an administrator and removes the admin bar:

add_action('after_setup_theme', function() {
    if (!current_user_can('administrator')) {
        show_admin_bar(false);
    }
});

Alternative version with more granular control over user roles:

add_action('after_setup_theme', function() {
    $allowed_roles = array('administrator');
    $user = wp_get_current_user();
    
    if (array_intersect($allowed_roles, $user->roles)) {
        show_admin_bar(true);
    } else {
        show_admin_bar(false);
    }
});

Where to Place the Code

1. In your theme's functions.php file

3. Using a code snippets plugin like Code Snippets
