Usage:

This filter hook enables you to influence and manipulate the WordPress field ‘user_nicename’ when the user is first created.

Unlike the “mbr/role/alternate” filter hook, this setting doesn’t get updated each time a user logs. The hook is only called once upon initial login so as not to disturb any other function which may rely on this setting (i.e. BuddyPress).

Parameters:

ActiveMember360 will pass the following parameters to your action function:

$nicename contains the default WordPress field value of “user_nicename”.
$first_name contains the default WordPress field value of “first_name”, which is obtained from ActiveCampaign (first_name).
$last_name contains the default WordPress field value of “last_name”, which is obtained from ActiveCampaign (last_name).
$arrCONTACT an array containing the contact record fields for the person who just logged in.

Example:

function my_mbr_nicename_hook($nicename, $first_name, $last_name, $arrCONTACT) {
  // In this simple example, we create a "user_nicename" consisting
  // of first name and last name separated by a dash
  return trim($first_name) . '-' . trim($last_name);
}
add_filter('mbr/nicename', 'my_mbr_nicename_hook',10,4);
