Ok, thank you.
I came up with a new solution just to count the number of values inside the two arrays:
add_action('acf/save_post', 'my_project_updated_send_email_custom', 10);
function my_project_updated_send_email_custom( $post_ID ) {
/* new and old field value */
$dokumenteOld = get_field('field_5ba11346c0289', $post->ID);
$dokumenteNew = '';
if (isset($_POST['acf']['field_5ba11346c0289'])) {
$dokumenteNew = $_POST['acf']['field_5ba11346c0289'];
}
/* get elements in array */
$countOld = count($dokumenteOld);
$countNew = count($dokumenteNew);
}
Now the problem is that both containt the same number of values when i a add a new line in the repeater field (the new count). I also can see the new value in both arrays.
Sorry, this is the last quesiton i ask i promise. Thank you so much for your help!
