Assign a value to a custom field?

I think the solution is here…
https://wordpress.org/support/topic/what-is-the-php-function-to-save-fields-in-um_user/#post-10965068
…but it’s still not 100% clear to me and it’s not working so far.

@wptechnology, I reply to your topic in mine as yours is closed.

You suggest…

global $ultimatemember;
$user_id = um_user('ID');
um_fetch_user($user_id);
$toupdate[] = array('name_of_field' => 'its_value');
UM()->user()->update_profile($toupdate);
update_user_meta($user_id, 'name_of_field','its_value');

In my context, 3 checkboxes to update when the profile is created, I think it would become this (in functions.php)…

add_action('um_after_save_registration_details', 'ui_registration_enable_notifications', 10, 2);

function ui_registration_enable_notifications( $user_id, $submitted ) {
	um_fetch_user($user_id);

	$toUpdate[] = array('profile_notif_new_post' => array (0 => 'enable'),
			    'profile_notif_new_comment' => array (0 => 'enable'),
			    'profile_notif_new_mention' => array (0 => 'enable'));
	UM()->user()->update_profile($toUpdate);

	update_user_meta($user_id, 'profile_notif_new_post', array (0 => 'enable'));
	update_user_meta($user_id, 'profile_notif_new_comment', array (0 => 'enable'));
	update_user_meta($user_id, 'profile_notif_new_mention', array (0 => 'enable'));
}

But I have several questions:

1/ Is global $ultimatemember; still needed in my case?

2/ What’s the differences in between the UM()->user()->update_profile() and the update_user_meta() updates? What are they respectively updating?

3/ For $toUpdate[], can we group 3 fields to update in 1 array like I did?

4/ I think checkbox values are set by an array like this array (0 => 'value'), correct?

5/ For the update_user_meta() update, we need to use 3 lines of code, we can’t group the update for the 3 fields, correct?

6/ How do we update checkboxes in meta? Also by an array like array (0 => 'value'), same?

I ask you those questions as something must be wrong. I have no error but it’s not working, the checkboxes are not ticked in the user’s profile.

Thanks!

Ok, this 2nd method works like a charm in the specific case of user registrations.
And the answers to my questions are:

– name: indeed, it should be the field meta_key + “[]” for checkboxes otherwise the value will be saved in plain text and not in the Ultimate Member specific format
– id: it looks like this parameter is useless in this specific case; we are not addressing anywhere for HTML fields
– value: yes, it’s the value in text (no TRUE|FALSE, YES|NO, 1|0, etc.), BUT… be careful to have the functions.php file in UTF8 if there are special characters in the text of the value (like French accents: “Activé”)

So lines like that are working fine for checkboxes:
echo '<input type="hidden" name="profile_notif_new_mention[]" value="enable" />';

Then I’ll mark this topic as “resolved” for the specific case of user’s registration, but I still need to clarify the 1st option for another context. But for that, I’ll open a new topic, it will be more clear.
