hi, i'm guessing that if you do a
smarty->display("index.tpl");
global variables are "lost"
cause i wrote a gallery (works fine with normal php)
now, i turn it into templated version
now stops working, (not the only one, also other scripts don't work anymore)

any way to change that?

no global variables are "lost".
they are just invisible inside functions and methods in php like the display() method of $smarty.

Sure, use either:

1) declare your intention to use a global var

global $var; // $var is now a reference to the global $var
$foo = $var;

or:

2) reference the superglobal (which is always in-scope):

$foo = $GLOBALS['var'];

More at the PHP manual:
http://php.net/language.variables.scope
http://php.net/reserved.variables

IMHO, globals suck. I usually get around it by having a static class that has functions that hold static vars to store data. With a little bit of thought you can can implement a class that organizes and unifies access to all of your shared data (static data, shared objects, singletons, etc)
