Naargh. Well, the Code is correct - but the Data it relies on isn't

$userinfo['birthday'] is already formatted at this point. But in member_start it isn't yet defined ...

So:

Hook: fetch_userinfo

PHP Code:

if (THIS_SCRIPT == 'member')
{
    $user['realbirthday'] = $user['birthday'];
} 


Hook: member_complete

PHP Code:

$curyear = vbdate('Y', TIMENOW, false, false);
$curmonth = vbdate('n', TIMENOW, false, false);
$curday = vbdate('j', TIMENOW, false, false);

$date = explode('-', $userinfo['realbirthday']);
if ($curyear > $date[2] AND $date[2] != '0000')
{
    $userinfo['age'] = $curyear - $date[2];
    if ($curmonth < $date[0] OR ($curmonth == $date[0] AND $curday < $date[1]))
    {
        $userinfo['age']--;
    }
    
    if ($userinfo['age'] >= 101)
    {
        unset($userinfo['age']);
    }
} 


10 minutes ... hmm. Too long
I am getting old - or tired.
