From a php page, how do I check to see if the user is logged in (as far as LSQL is concerned) and (1) if so, allow them to see the page or (2) if not, send them to the appropriate login, then redirect to the php page? In essence, I need a php equivalent to add.cgi.

Also, are there any globals/functions available to use similar to how <%Username%> is used on the cgis like add and modify.

Thanks
