Smarty

[Dummkopf]

Hi all,

I have several template-folders, one for each skin.

Because it may happen, that a template-file is called the same as another one in a different skin, I call them with compile_id = skin_name.

In the game-environment there are three skins available.

After certain gamer's-actions I need to delete the cache for the template ressourcen.tpl for a certain player. (cache_id = "user|user_id|language")

I want to clear all caches from templates, which are called 'ressourcen.tpl' and are in cache-group "user|145". (clear-cache(ressourcen.tpl, user|145)

The cache for ressourcen.tpl isn't deleted, though, because I don't give Smarty any compile_id.

Is there any way to delete template-caches with EVERY existing compile_id just with template-name and cache-group?

Make sure compile_id is null when you clear the cache. (eg. don't set $smarty->compile_id, or set it to null first)

[Dummkopf]

If I set it to NULL the files are not cleared, because I fetched them with a certain compile_id != NULL.

is_cached('ressourcen.tpl', 'user|145|de', 'skin_1') => TRUE

The language of player 145 and his skin are unknown.
Nevertheless I want to clear ALL cache files for the template ressourcen.tpl, which are in cache-group "user|145".

If there is no possibility to do this, I will have to walk through every possible combination of languages and skins. (Two languages and three skins would mean: 6 function calls every time I want to clear a cache-file of another player. ['user|145|de', 'skin_1'; 'user|145|de', 'skin_2'; etc.])

rule of thumb: if you pass a resource-name to clear_cache() there is never more than one file deleted. (read: you are right, you'd have to call clear_cache() for all possible compile_ids).

use null as resource-name to clear the whole cachegroup for all compile_ids. if you really only want to delete "ressourcen.tpl", make "ressourcen" part of the cache_id. but often it's enough to clear cached content by cache_id and not by template.

[Dummkopf]

Is there at least a possibility to delete whole cache-groups?

clear_cache('ressourcen.tpl', 'user|145', 'skin_1') doesn't clear any file but should clear the following:

('r.tpl', 'user|145|de', 'skin_1')
('r.tpl', 'user|145|en', 'skin_1')
('r.tpl', 'user|145|fr', 'skin_1')

Referring to your tip:

ressourcen.tpl would be fetched via ('ressourcen.tpl', 'user|145|ressourcen|de', 'skin_1') for example and cleared via clear_cache(NULL, 'user|145|ressourcen', NULL), right?
I will just check whether it really clears the whole cache-group for EVERY compile_id. If so, I will change it accordingly. Thanks for the idea!

[mohrt]

The compile id is essentially treated as the last cache group.

You can think of it like this:
$smarty->clear_cache('index.tpl','a|b|c','foobar');

If you think of it like a file system, clear_cache will try to clear the file:
/a/b/c/foobar/index.tpl

Now we leave the template null:
$smarty->clear_cache(null,'a|b|c','foobar');

and this clears everything under:
/a/b/c/foobar/*

Now we leave the compile_id null but supply the template:
$smarty->clear_cache('index.tpl','a|b|c',null);

and this clears the particular cache file:
/a/b/c/index.tpl

which of course won't work. What you are trying to accomplish is:
/a/b/c/*/index.tpl

which the cache system has no concept of, it only works left-to-right.

So messju is correct, you need to put your "grouped" templates into their own cache group, so something like this:

$smarty->clear_cache(null,'a|b|c|mygroup',null);

will clear out:

/a/b/c/mygroup/*

It's working fine now. Thank you very much for your help!

The fetching has now got this format:

Template: $template
CacheID: [user | $userID |] $template | [$specialCacheID |] $language
CompileID: $skin

To clear a certain template-cache of a certain player, I can use:

(clear_cache)
Template: NULL
CacheID: user | $userID | $template [| $specialCacheID]
CompileID: NULL

which clears all template files $template in cache-group user|userID for every skin and every language!

Smarty is so great!
