Smarty缓存集合 - Smarty教程™

Cache Groups [缓存集合]

你可以通过建立cache_id集合做更祥细的集合体。在cache_id的值里用竖线"|"来分开子集合。你可以尽可能多的包含子集合。 


Example 14-9. cache_id groups
例14-9.cache_id集合

require('Smarty.class.php');
$smarty = new Smarty;

$smarty->caching = true;

// clear all caches with "sports|basketball" as the first two cache_id groups
$smarty->clear_cache(null,"sports|basketball");
// www.yiibai.com/smarty
// clear all caches with "sports" as the first cache_id group. This would
// include "sports|basketball", or "sports|(anything)|(anything)|(anything)|..."
$smarty->clear_cache(null,"sports");

$smarty->display('index.tpl',"sports|basketball");


技术提示:缓存集合并不像cache_id一样对模板使用路径。比如,如果你display('themes/blue/index.tpl'),那么在"themes/blue"目录下你并不能清除缓存。想要清除缓存,必须先用cache_id把缓存集合,像这样display('themes/blue/index.tpl','themes|blue');然后就可以用clear_cache(null,'themes|blue')清除blue theme(蓝色主题?!老外也真会叫...)下的缓存。
