void is_cached(string template, [string cache_id])
This returns true if there is a valid cache for this template.
This only works if caching is set to true.
Example 13-18. is_cached $smarty->caching = true;
if(!$smarty->is_cached("index.tpl")) {
// do database calls, assign vars here
}
$smarty->display("index.tpl"); |
|
You can also pass a cache id as an an optional second parameter
in case you want multiple caches for the given template.
Example 13-19. is_cached with multiple-cache template $smarty->caching = true;
if(!$smarty->is_cached("index.tpl","FrontPage")) {
// do database calls, assign vars here
}
$smarty->display("index.tpl","FrontPage"); |
