IF anyone is interested, I got it working.
For some reason the field had a random name instead of the one I gave it in the ACF admin screen. I left a little snippet in so you can easily find the field name through debugging. There is probably a better way to do this but I’m not intimately familiar with all things ACF.
Also note that my custom taxonomy is “expert” so change that out for yours.
add_action('edit_user_profile_update', 'wda_connect_user_terms');
add_action('personal_options_update', 'wda_connect_user_terms');
function wda_connect_user_terms($user_id) {
$terms = $_POST["acf"]['field_59eeaa8ebb291'];
// comment in this snippet to find field name
/* $fields = $_POST;
* echo '<pre>';
* var_dump($fields);
* echo '</pre>';
*/
if ($terms) {
// An array of IDs of categories we want this post to have.
$cat_ids = $terms;
/*
* If this was coming from the database or another source, we would need to make sure
* these were integers:
*/
$cat_ids = array_map( 'intval', $cat_ids );
$cat_ids = array_unique( $cat_ids );
$term_taxonomy_ids = wp_set_object_terms( $user_id, $cat_ids, 'expert' );
if ( is_wp_error( $term_taxonomy_ids ) ) {
// put debug code here
} else {
// put debug code here
}
}
}
