update_field with post_object

I have several posts to insert a custom field, use the ‘post object’ in the case, as I use the update field for post object?
What I am trying to use:

$supplier_one = 'my supplier';
$supplier_two = 'my supplier TWO';
$post_id_one = 555;
$post_id_two = 556;

update_field('suppliers', $supplier_one, $post_id_one)
update_field('suppliers', $supplier_two, $post_id_two)

Hi @Rank

To save the value of a post_object field, you should save the ID of the post.
If the field has been set as a multiple value field, you need to save an array of post ID’s

Does this help?

It does, although, It would be awesome to be able to remove or add individual elements, and not have to replace the entire value.

I do need to add both post_meta:

add_post_meta( $insert_q_key_id, ‘q_key_type’, (int)$q_key_type ); // Q Key Type
And for ACF:

update_field( “field_52c737a413e07”, (int)$q_key_type, $insert_q_key_id ); // Q Key Type
And the rest of the answer “should” be covered by wp_set_object_terms:

wp_set_object_terms( $insert_q_key_id, (int)$q_key_type, ‘q_key_type’, true );
However, this function is not fully available at the point I need it – so the answer was to create a simple replacement for this function:

/**
* simple wp_set_object_terms replacement as not available during API call
*
* @since 0.4
* @global Object $wpdb
* @param integer $object_id
* @param integer $tt_id
* @return Mixed Integer of inserted row on success | Boolean false
*/
public function q_wp_set_object_terms( $object_id = null, $tt_id = null )
{

if ( ! $object_id || ! $tt_id ) { return false; }

global $wpdb;

if ( $wpdb->insert( $wpdb->term_relationships, array( ‘object_id’ => (int)$object_id, ‘term_taxonomy_id’ => (int)$tt_id ) ) ) {

return $wpdb->insert_id;

}

// if not ##
return false;

}
Which I can call using a static class instance ( as the method is part of a separate class in my case… ):

Q_Key::q_wp_set_object_terms ( $insert_q_key_id, (int)$q_key_type );
