Update_field for user field

I have a question and i can’t seem to find any related problems. I am trying to set a user inside a user field, this user field is inside of a repeater. What does the user field require to update the field? Currently i hardcoded this example:

update_sub_field( array('related_player', 1, 'reservation_participant'), 'user_3',  204);

Where related_player is my repeater field name and reservation_participant is my sub_field name.

Any help would be appreciated.

Does the repeater and sub field already exist as a value in the database or are you setting a value for a field that has never been set before?

I do see that the fields are being set in the wp_postmeta and also the value is set see this image:

I think you have the value and post ID arguments backwards

https://www.advancedcustomfields.com/resources/update_sub_field/

This is what you have

update_sub_field(
  array('related_player', 1, 'reservation_participant'), // selector
  'user_3', // value
  204); // post ID

I am sure that the post_id is 204, but i am not quiet sure about the value of the user. The sub field is a user field. Does it even accept ‘user_3’ as value or do i need to specify only the user id?

It does not matter what the values are, you have them backwards.

argument 2 should be the value
argument 3 should be the post ID — ‘user_3’

Unfortunately this isn’t the case. To test if these rows even exist i tried this:

if (function_exists('have_rows')) {
        while (have_rows('field_61c18b86ee6fd')) {
            dd('test');
        }
    }

This did not return the expected ‘test’, ‘field_61c18b86ee6fd’ is the key of the repeater. I tied to use the sub fields key and this also didn’t return the expected ‘test’. I wondered what it could be until i found this.

In the database there is a related_player_0_reservation_participant and a _related_player_0_reservation_participant the related_player_0_reservation_participant was not filled with an id. Updating this field like so: update_field('related_player_0_reservation_participant', 1, 204); did the trick for me. Anyways thanks for your help.
