A couple of quick questions...

[bu22]

If someone can help me out on the following 2 questions , I'd be very grateful!

1) Is there a way in PHP to check whether the script has been called via SSL? (E.g. someone clicked "https://.../script.php")

2) I'm using the smarty template engine, and wondered if there is a way to simply test if a smarty variable has been set or not (in the template). I know you can do this: {if $var != ""} but surely there's a better way.....? Couldn't seem to find it in the docs.

Well - detecting HTTPS is generally straight forward.

The method to use depends on how your PHP has been installed (i.e. as a module, or as standard cgi).

If you use the modular version: -

Just check that

$HTTP_SERVER_VARS["HTTPS"] == 'on'

or, if you don't find that this is set when you are behind HTTPS (do a quick check on what get set on your server behind https), just use

$GLOBALS['SERVER_PORT'] == 443

since the default port for https is 443 (you may have to change this to a different port if your server admin has modified this at all - but this is unlikely).

Hope this helps
