What is the if conditional code, in plugin for : if coppauser is 0

[Basketmen]

Hi guys,

i want to make a plugin with hook register_addmember_process or register_addmember_complete


i need if conditional code, in plugin for :
if coppauser is 0



coppauser is a variable in registration, thats mean the user is not COPPA User
i want to set something for non COPPA User using a plugin
please help guys, what s the if conditional looks like




i already tried this

if (!$userinfo['coppauser'])

but its not working, maybe because the user is still registered as a user yet

and this

if ($userdata->set('coppauser', 0))

but got this error message :

Fatal error: Field coppauser is not defined in $validfields in class vB_DataManager_User in /includes/class_dm.php on line 485
