Add function to add current_page_item to menus

[getdave]

Make sure that current_page_item class is added to menus. Particularly useful for create sub navigation for a CPT because be default WP doesn't add the current class to wp_list_pages() output when used with CPT.

function tanlinell_page_css_class( $css_class, $page ) {
    global $post;
    if ( $post->ID == $page->ID ) {
        $css_class[] = 'current_page_item';
    }
    return $css_class;
}
add_filter( 'page_css_class', 'tanlinell_page_css_class', 10, 2 );
