I am trying to populate a custom field called Customer Type in checkout with the current user role. I tried the below in my functions.php of my child theme and thought it would work but it does nothing. Can anyone tell me what I might be doing wrong?

$user = wp_get_current_user();
function onboarding_update_fields( $fields = array() ) {

   $fields['customertype'] = $user;

   return $fields;
}

add_filter( 'woocommerce_checkout_fields', 'onboarding_update_fields' );

• WooCommerce and other 3rd party plugins are off topic and not in this stacks scope. You should ask via their official support routes or in their communities. – Tom J Nowell ♦ Commented Apr 14, 2021 at 10:15

wp_get_current_user() returns a user object. You can't output objects directly.

Proceed by getting the users roles like $roles = (array)$user->roles;. Note that this returns an array though, so you will probably want to use the first element with $roles[0].

Your code might look like this (untested):

function onboarding_update_fields( $fields = array() ) {
   $user = wp_get_current_user();
   $roles = (array)$user->roles;
   $fields['customertype'] = $roles[0];
   return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'onboarding_update_fields' );

Additionaly, you might want to check if the user is logged in, otherwise there might not be a user and role available.
