Usage:

This filter hook enables you to influence and manipulate the WordPress field ‘display_name’ 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:

$display_namecontains the default WordPress field value of “display_name”.
$first_namecontains the default WordPress field value of “first_name”, which is obtained from ActiveCampaign (first_name).
$last_namecontains the default WordPress field value of “last_name”, which is obtained from ActiveCampaign (last_name).
$arrCONTACTan array containing the contact record fields for the person who just logged in.

Example:

function my_mbr_display_name_hook($display_name, $first_name, $last_name, $arrCONTACT) {
  // In this simple example, we create a "display_name" consisting
  // of first name and last name initial only.
  return ucfirst(trim($first_name)) . ' ' . strtoupper(substr(trim($last_name),0,1)) . '.';
}
add_filter('mbr/display_name', 'my_mbr_display_name_hook',10,4);
