I’ve got a one to many relationship between CPT Album and CPT Review wit the field Album
I want the field Artist to be automatically updated once an album is chosen in the CPT review
Hi John,
it’s a field that is updated with the value of a field in an other CPT.
therefore I use the post id store in an object relation field.
CPT Album
– Title (album name)
– Artist
– Lenght
– number of title
– genre …
CPT Review
– Title (Review sentence)
– Album (object relation field pointing to CPT album)
– Artist (updated from Albumn CPT through the object relationship field Album with Artist)
function acf_review_album_band_update( $field ) {
$field = get_field('album_band',get_field('review_album'));
return $field;
}
add_filter('acf/update_value/name=review_album_band', 'acf_review_album_band_update');
it works, but it updates the artist name only when I publish, any chance to have something more dynamic ?
