Hi,
I have two custom post types, Events and Places. Every event has a post relationship field to assign the event to a place. Every place post has a Google Maps field (address). I want to fetch and clone the address field value from the related place to a separate adress field (event_address) on the event when I save the event.
Can someone please point me in the right direction here?
Thanks!
add_action('acf/save_post', 'save_event_update_address', 20);
function save_event_update_address($post_id) {
if (get_post_type($post_id) != 'events') {
// not and event post, bail
return;
}
// get location post ID
// you said it's a relationship field, a relationship field will turn an array of posts
// I am setting the 3rd parameter because we only need the IDs
$related_places = get_field('relationship_field_name', $post_id, false);
if ($related_places) {
$place_id = $related_places[0];
$address = get_field('address_field_on_place_name', $place_id);
update_field('address_field_on_event_name', $address, $post_id);
}
}
I know this is an old post and was solved, but wanted to ask, what if the Events fields were in repeater fields? I tried to modify as below, but not getting the right results.
add_action('acf/save_post', 'save_event_update_address', 20);
function save_event_update_address($post_id) {
if (get_post_type($post_id) != 'events') {
// not and event post, bail
return;
}
// get location post ID
// you said it's a relationship field, a relationship field will turn an array of posts
// I am setting the 3rd parameter because we only need the IDs
$related_places = get_sub_field('relationship_field_name');
// also the
if ($related_places) {
$place_id = $related_places[0];
$address = get_field('address_field_on_place_name', $place_id);
update_sub_field('address_field_on_event_repeater_name, $address, $post_id);
}
}
In order to update a sub field you must loop over the repeater in the same way that you’d loop over it when displaying values https://www.advancedcustomfields.com/resources/update_sub_field/
