Question

I’m using this code to add some meta boxes to the home page in WordPress (which is ID 6):

function add_page_metaboxes() {
    add_meta_box('meta_p_sub', 'Page Subtitle', 'meta_p_sub', 'page', 'normal', 'high');
    $post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'];
    if ($post_id == '6') {
        add_meta_box('meta_hp_thing', 'Homepage Thing', 'meta_hp_thing', 'page', 'normal', 'low');
    }
}
add_action('add_meta_boxes', 'add_page_metaboxes');

I want to be able to use this on several sites, and the ID won’t always be ‘6’. I’ve tried to use if (is_home()) {... and if (is_front_page()) {... but that doesn’t seems to work.

How can I find out which ID is set in WP Admin > Settings > Reading > Front Page and use that?

Cheers!
Ben

Answer 1

Front page ID is stored in page_on_front option.

$post_id = get_option( 'page_on_front')
