Allow user edit widgets

Question

I have user who can edit and delete posts.

I want give him access to widgets too, but not to whole Appearance, like theme change, menu,...

Is there some solution?

Thanks and sorry if my english is not good.

Answer 1

The edit_theme_options capability controls access to the widgets page but also to the menus page.

You can then remove the menus submenu from appearance for a specific role, and if someone tries to get there by url, redirect it :

/**
 * Remove the "Menus" submenu from Appearance
 */
function remove_menus()
{
    if (in_array('administrator', wp_get_current_user()->roles))
    {
        remove_submenu_page('themes.php', 'nav-menus.php');
    }
}
add_action('admin_menu', 'remove_menus');

/**
 * Redirect nav-menus.php to the dashboard
 */
function redirect_menus()
{
    global $pagenow;
    if ($pagenow === 'nav-menus.php' && in_array('administrator', wp_get_current_user()->roles))
    {
        wp_redirect(admin_url());
    }
}
add_action('admin_init', 'redirect_menus');

Of course, replace the administrator role by the one you want.
