Is there way to rename user role name without plugin?

Question

Is there anyway to rename a user role name via hook, instead of using plugin?

Answer 1

function change_role_name() {
    global $wp_roles;

    if ( ! isset( $wp_roles ) )
        $wp_roles = new WP_Roles();

    //You can list all currently available roles like this...
    //$roles = $wp_roles->get_names();
    //print_r($roles);

    //You can replace "administrator" with any other role "editor", "author", "contributor" or "subscriber"...
    $wp_roles->roles['administrator']['name'] = 'Owner';
    $wp_roles->role_names['administrator'] = 'Owner';           
}
add_action('init', 'change_role_name');

Answer 2

A simple solution would be to just add a user role using add_role, that way you can name it whatever you want and add whatever capabilities you want. http://codex.wordpress.org/Function_Reference/add_role

You can create a custom localization file. Get this file: http://svn.automattic.com/wordpress-i18n/pot/trunk/wordpress.pot and edit using PoEdit tool (for example). In next step save localization file as en_GB.mo (or other) and edit wp-config file:

define ("WPLANG", "en_GB");
