Hey everybody,

i want to save an URL-Parameter that we also store in a Browser-Cookie to an Order. This way i want to check if Cooperations, Google Ads etc. work and add something to the order if e.g.someone came from a Blog-Post-Cooperation. I dont want to use Coupons for that.

Any idea?

I already created ACF Text-Fields for the Orders but i dont know how to save the cookie-value in it.

All the best

Will this field be something that the person submitting the order should be able to see?

No – only for the backend / me, packing packages etc.

The first thing I would do is to not show the field on the front end. For this use an acf/prepare_field filter

your_filter_name($field) {
  if (!is_admin()) {
    return false;
  }
  return $field;
}

As far as saving the cookie value to the field, there are a couple of way you can do this. I would try using an acf/save_post action with a priority > 10

I do not have all the details for this function, just an outline.

function your_save_function_name($post_id) {
  // I am not exactly sure what goes in post type check
  // this should be the WC order post type I think
  if (get_post_type($post_id) != 'the right post type') {
    return;
  }
  // check the value of the cookie
  if (!empty($_COOKIE['your-cookie-name')) {
    $value = code_here_to_get_value_to_set(); // depends on how your cookie value is stored
    // use the field key to update the field --- NOT the field name
    update_field('field_XXXXXXXX', $value. $post_id);
  }
}
