WP_Query Integration

Query posts (or other post types) by relationship using standard WP_Query.

Recommended: content_relation

$query = new WP_Query([
    'content_relation' => [
        'post_id'   => get_the_ID(),
        'type'      => 'related_to',
        'direction' => 'outgoing', // or 'incoming'
    ],
    'posts_per_page' => 10,
]);

Registered query vars (so WordPress does not strip them): content_relation, wpcr, related_to, relation_type. See the plugin’s query class docblock for full shapes.

Legacy formats

• wpcr: 'wpcr' => [ 'from' => 123, 'type' => 'related_to', 'direction' => 'outgoing' ]
• related_to: 'related_to' => 123, 'relation_type' => 'related_to'

Delegation (future core API)

If WordPress adds a native relationship API, you can skip this plugin’s JOIN/WHERE by returning true from the filter:

add_filter( 'ncr_skip_relationship_query', function( $skip, $query ) {
    // e.g. if core query var is set, let core handle it
    return $skip;
}, 10, 2 );
