smart原则|Smarty 缓存集合简单讲解

【www.bbyears.com--smarty模板】

You can do more elaborate grouping by setting up cache_id groups. This is accomplished by separating each sub-group with a vertical bar "|" in the cache_id value. You can have as many sub-groups as you like.

Example 14-9. cache_id groups

 代码如下

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

$smarty->caching = true;

// clear all caches with "sports|basketball" as the first two cache_id groups

 代码如下 $smarty->clear_cache(null,"sports|basketball");

// clear all caches with "sports" as the first cache_id group. This would
// include "sports|basketball", or "sports|(anything)|(anything)|(anything)|..."

 代码如下

$smarty->clear_cache(null,"sports");

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

在不知如何清除 Smarty 中带 id 的缓存时，找到了手册中上面说明，可惜英文太差，不知所云。

在 csdn 中找到网友帖子，看完后恍然大悟。

就是在缓存页面的时候像这样：

 代码如下 $smarty-> display( "basic.tpl ", "groupxxx| ".$cache_id);

然后要清这个groupxxx组下的所有缓存，则像这样：

 代码如下 $smarty-> clear_cache(null, "groupxxx ");
