I am trying to map an ACF Relationship field during the post creation process via GravityForms form. For most fields I can use a snippet of code as follows:
add_action('gform_advancedpostcreation_post_after_creation_7', function ($post_id, $feed, $entry, $form) {
$acf_field = rgar( $entry, '17' );
update_field( 'field_63d65a709cc93', $acf_field, $post_id );
}, 10, 4 );
However, for relationship fields this method does not work.
I’m sure I’m missing something very simple! Any pointers would be much appreciated.
🙂
NB: The relationship field is set-up to allow only a single selection.
A relationship field holds and array of ID values
// if the might already have a value
$value = get_field('field_63d65a709cc93', $post_id);
if (empty($value)) {
$value = array();
}
$value[] = intval(rgar($entry,'17'););
update_field('field_63d65a709cc93', $value, $post_id);
Hi, John –
Thank you for your support. For some reason this isn’t working. I suspect it’s because I have the relationship field set-up to return the Post Object – not the Post ID. Would this make a difference?
I’ve tried changing it over to return the Post ID but that just creates huge knock effects for the rest of the site – and I don’t want to make my task any more complicated than it is already!
my mistake, you need to get the current value unformatted, do this
$value = get_field('field_63d65a709cc93', $post_id, false);

Thanks again but that won’t work because it has to get the value from the form:
$value[] = intval(rgar($entry,'16'));
If I just put a clean number into the value it works perfectly:
$value = "1234"
I need to get the related post ID from this (which is returning the Post Object):
rgar($entry,'16')
I have no idea what rgar() is. but if it’s returning a post object then this might work
$post = rgar($entry,'16');
$post_id = $post->ID;
