If it helps anyone, I put together this function for ACF 4 to get the correct field key for a given post and field name to match:
/**
* Get field key for field name. ACF 4
* Will return first matched acf field key for a given field name to match.
*
* This function will return the field_key of a certain field.
*
* @param $post_id int The post id to check.
* @param $field_match String The field name to match in the query in SQL format e.g. '%versions%'
* @return
*/
private function acf_get_field_key( $post_id, $field_match ) {
global $wpdb;
$posts = $wpdb->get_results( $wpdb->prepare( "SELECT ID FROM $wpdb->posts where post_type=%s", 'acf' ) );
$rows = $wpdb->get_results( $wpdb->prepare("SELECT meta_key,meta_value FROM $wpdb->postmeta WHERE post_id = %d AND meta_key LIKE %s AND meta_value LIKE %s", $posts[0]->ID, 'field_%', $field_match), ARRAY_A);
$field_data = unserialize( $rows[0]["meta_value"] );//not sure why it is in there twice...
return $field_data['key'];
}
I am also able to populate a repeater field, but only by hard coding the field key. Is there a way around this so that I can run this on any WordPress install without updating the field key by hand in code for each one?
Thank you,

Hello @elliot
Thank you for the excellent products!
I have been looking at as many resources as I can find online, trying directly calling update_field() as well as using acf/load_value, but I cannot seem to set a repeater field on a newly created page (all in code). Do you have any code snippets wherein a page is created and then an acf repeater field is successfully populated and then read back?
Thank you
Jasper
