Retrieving data from database

[LBC]

Ok.  So it will be something like this.
However you figure out the length, it needs to wind up as a 6 or 12.
$length = 6;  

then
echo date('Y-m-d', strtotime("+".$length." months", strtotime($user->data()->validity)));

like this?

<?php echo date('Y-m-d', strtotime("+".$length=6." months", strtotime($user->data()->validity))); ?><
