Last active December 12, 2020 19:13
An example of getting the current domain post ID in WP Landing Kit. Might be of use if you are loading up ACF fields on a domain post or something similar.
<?php
// e.g; 'mydomain.com'
$current_host = $_SERVER['HTTP_HOST'];
// This will return a WPLK_Domain object, if the domain can be found. Otherwise, NULL.
$domain = wplk_get_domain( );
if($domain){
$domain_id = $domain->post_id();
