Hey James…. sorry this gets embarrasing for me. But i still have no idea. I need to write a new user into my user database. The fields firstname and lastname exist without acf. I dont know how to create something like:
<?php
acf_form(array(
'user_id' => 'new_user',
'user_lastname' => 'formfield_lastname',
'user_firstname' => 'formfield_firstname',
'user_company_acf' => 'formfield_company'
?>
Im so sorry… but this function is essential for my website.
