 |
|
I was wondering for a moment.
Do included/extended templates inherit compile_id of the caller?
And related question, can I specify compile_id as a variable in template?
Let's say I have tree-like category menu that takes hell of a lot of time to build right, and a number of articles in a given category. The category id is used as compile_id for the menu, but articles, obviously, using their own compile_id (article id).
Category id is passed to the template as variable, can I use it to assign compile_id to menu? |

You have wrong understanding of compile_id and cache_id.
The compile_id is used to keep different compilation results of same template separated. This is useful if you want for example use the same template source with different pre- or postfilters.
If caching is enabled you use article id as cache_id to create different cache files with the rendered output for each article.
Included templates do inherit the cache_id (and compile_id) of the caller by default. But you can create a separate cache file for the category menu by assigning the category to the cache_id attribute like
| Code: | | {inclunde file='category.tpl' cache_id=$category} |
see http://www.smarty.net/docs/en/language.function.include.tpl
Enabling caching and using cache_id's does just save the time for rendering the content.
Must time is spend for obtaining article and may be category data from a database and assign it to template variables. This is only necessary when the cache file is invalid.
Smarty::isCached() does solve this.
see http://www.smarty.net/docs/en/api.is.cached.tpl
| Code: | if(!$smarty->isCached('article.tpl', null, $article_id)) {
// do article database calls, assign vars here
}
if(!$smarty->isCached('category.tpl', null, $category)) {
// do category database calls, assign vars here
}
$smarty->display('article.tpl', null, $article_id);
|
{extends} inherits always compile_id and cache_id from the calling template.
They have no function. |

Err, yes. Sorry for the confusion.
I don't know, what I have been writing.
I definitely did mean cache_id. |
