is_cached

void is_cached( template,  
  cache_id);  
string template;
[string cache_id];
 

Isso retorna true se há um cache válido para esse template. Isso somente funciona se caching está setado para 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");

Você pode também passar um cache id como um segundo parâmetro opcional no caso você quer múltiplos caches para o template dado.

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");
