Smarty

[ewebzerg]

we alway use:
display.php?id=xxx
xxx is the record's id value.

how to cache display.php?id=1,display.php?id=2;display.php?id=3... to file cache ?? is it a good idea ?

[Wom.bat]

use a cache-id like so:
$smarty->display("template.tpl", $_REQUEST["id"]);
I'd strongly recommend that you validate $_REQUEST["id"] before, and set a valid value if it's invalid... otherwise, someone can easily fill your server / quota by calling the URL with random "id" parameters
read http://smarty.php.net/manual/en/caching.php
there you can find everything you might want to know (it's a good idea to read the documentation _first_ anyway )
