Stored user Date of Birth
Other plugins may hold data about your users, for instance a date of birth. It is possible, if they are logged in, to use this information to check if Age Gate should challenge them.
Let’s assume we have a BuddyPress installation and have captured a users date of birth when they registered, we can then use the age_gate_restricted
filter to test their age:
add_filter('age_gate_restricted', 'buddy_press_test', 10, 2);
function buddy_press_test($restrict, $meta){
if(function_exists('xprofile_get_field_data')){
// assuming a date format of YYYY-MM-DD
$dob = xprofile_get_field_data('Date of Birth', get_current_user_id());
if($dob){
$from = new DateTime($dob);
$to = new DateTime('today');
$age = $from->diff($to)->y;
return ($meta->age >= $age);
}
}
return $restrict;
}
This could be applied to custom date from any number of sources.
Note: in JavaScript mode, heavy calls to this filter could result in a delay to showing the challenge.
