SignupService::matches_posted_attributes │ private │ WC 1.0

No Hooks.

Returns

bool. True if the notification matches the posted attributes.

$result = $this->matches_posted_attributes( $notification, $posted_attributes ): bool;
$notification(Notification) (required)
The notification.
$posted_attributes(array) (required)
