How do I check if the current user has a permission?
<?php
if ($gBitUser->hasPermission('bit_p_admin_cms')) {
This user has permission!
}
?>
NOTE: if you want to exit and display an error message if they don't have permission, then:
<?php
$gBitSystem->verifyPermission( 'bit_p_view' );
?>
This displays a standard "You do not have permission!" error message.
