Ok I managed to do it 🙂
Using add_row
after the form submission, here is the code:
add_action('acf/save_post', 'fs_sequence_progress');
function fs_sequence_progress( $post_id ) {
if ( ! is_admin() ) {
$seq_title = get_the_title();
$seq_id = get_the_id();
$uid = get_current_user_id();
$row = array(
'page_title' => $seq_title,
'page_id' => $seq_id
);
add_row('pages_ok', $row, 'user_'.$uid);
}
}
