Relationships Custom Fields
If you’re using “Relationship” field types and wonder why these fields are empty on freshly crossposted posts, the answer is pretty simple – it is because the same posts (or terms) have different IDs on different websites.
If you’re using ACF, you just need to install and activate an add-on from here.
But what if you’re not using Advanced Custom Fields? Maybe your relationships fields were created with another custom fields plugin or maybe even coded in your WordPress theme. By the way, there is also a separate add-on available for MetaBox and JetEngine plugins.
First of all, please install one of the add-ons below depending on which plugin you’re using.

Once the add-on is installed and activated, you need to find out your relationships custom fields meta keys and add them into the snippet below.
For posts, pages or any other custom post types:
add_filter( 'rudr_crosspost_post_relationship_meta_keys', function( $meta_keys ) {
// add first field
$meta_keys[] = 'related_posts';
// add second field
$meta_keys[] = 'related_pages';
return $meta_keys;
} );For categories, tags and any other custom taxonomies:
add_filter( 'rudr_crosspost_term_relationship_meta_keys', function( $meta_keys ) {
$meta_keys[] = 'related_categories';
return $meta_keys;
} );The snippet should be inserted to “Site 1” – the site you’re about to crosspost from. In case you don’t know how – please read this.
A couple more things to keep in mind:
- Items listed in your “Relationships” fields, should be crossposted first, in case of terms – items with the same slugs should exist on “Site 2”.
- If you’re using a custom field for taxonomy terms, the terms in this field should belong to the same taxonomy.
