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.
You can think of cache groups like a directory hierarchy. For instance, a cache group of
'a|b|c'could be thought of as the directory structure'/a/b/c/'.clear_cache(null,'a|b|c')would be like removing the files'/a/b/c/*'.clear_cache(null,'a|b')would be like removing the files'/a/b/*'.If you specify a
$compile_idsuch asclear_cache(null,'a|b','foo')it is treated as an appended cache group'/a/b/c/foo/'.If you specify a template name such as
clear_cache('foo.tpl','a|b|c')then Smarty will attempt to remove'/a/b/c/foo.tpl'.You CANNOT remove a specified template name under multiple cache groups such as
'/a/b/*/foo.tpl', the cache grouping works left-to-right ONLY. You will need to group your templates under a single cache group heirarchy to be able to clear them as a group.
Cache grouping should not be confused with your template directory
heirarchy, the cache grouping has no knowledge of how your templates are
structured. So for example, if you have a template structure like
themes/blue/index.tpl and you want to be able to
clear all the cache files for the “blue” theme, you will need
to create a cache group
structure that mimics your template file structure, such as
display('themes/blue/index.tpl','themes|blue'), then
clear them with
clear_cache(null,'themes|blue').
Example 14.9. $cache_id groups
<?php
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');
// 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');
// clear the foo.tpl cache file with "sports|basketball" as the cache_id
$smarty->clear_cache('foo.tpl','sports|basketball');
$smarty->display('index.tpl','sports|basketball');
?>
