Elliot! you’re a hero!
Stupid of me not to think about debugging first! You were right on point about that $target_product
was not a single, but an array of post objects!
so using this updated variable $review_target_product = $target_product['0']->ID;
made my code work!
For anyone interested in the future, this is all the code I used to construct my post titles in my functions.php
//Auto add and update Title field:
function my_post_title_updater( $post_id ) {
$my_post = array();
$my_post['ID'] = $post_id;
$manufacturer = get_field('manufacturer');
$target_product = get_field('target_product');
$review_target_product = $target_product['0']->ID;
$manufacturer_target = get_field('manufacturer', $review_target_product);
if ( get_post_type() == 'manufacturer' ) {
$my_post['post_title'] = get_field('manufacturer_name');
} elseif ( get_post_type() == 'products' ) {
$my_post['post_title'] = get_field('kitName') . ' (' . get_field('manufacturer_name', $manufacturer->ID) . ' ' . get_field('kitNumber') . ')';
} elseif ( get_post_type() == 'reviews' ) {
$my_post['post_title'] = get_field('kitName', $review_target_product) . ' (' . get_field('manufacturer_name', $manufacturer_target) . ' ' . get_field('kitNumber', $review_target_product) . ')';
}
// Update the post into the database
wp_update_post( $my_post );
}
// run after ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'my_post_title_updater', 20);
