In 'Smarty::CACHING_LIFETIME_SAVED' mode.
If call 'isCached()' before 'setCacheLifetime()', the 'cache_lifetime' does't change any more.

e.g.

Code:
$smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);
$smarty->setCacheLifetime(0);

if ($smarty->isCached($template, $cache_id)) {
  // ...
}

$smarty->setCacheLifetime(300); // No use at all
$smarty->display($template, $cache_id);



I test it in 3 versions of smarty.

3.0.5 => works well, there's no problem
3.0.7 => 'cache_lifetime' is locked after 'isCached()' called
3.1.7 => 'cache_lifetime' is locked after 'isCached()' called

Try this:

Code:
$smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);
$smarty->setCacheLifetime(0);
$tpl = $smarty->createTemplate($template, $cache_id);

if ($tpl->isCached()) {
  // ...
}

$tpl->setCacheLifetime(300);
$tpl->display();

Thanks a lot, it works.

But why 'cache_lifetime' is locked after 'isCached()' calle, it's new feature or just a bug?

it's neither. It's behavior.

fetch(), display(), isCached(), … all access a real deal template object. Those are their own objects in Smarty3.1. This allows you to create multiple templates from the same smarty instance, but all differing in configuration, data and whatnot.

that createTemplate() trick is pretty much what smarty does internally. With the exception that you now know the referenced template and can access its properties.

I admit the docs could do a much better job at communicating this. there is a doc for createTemplate() but nothing says why you'd actually want to use this.

Thanks a lot for your explanation.
Learn a lot.

For clearCache():

Use
Code:
$template_object = $smarty->createTemplate($template, $cache_id);
$template_object->clearCache();

or
Code:
$smarty->clearCache($template, $cache_id);


The first one seems not work.

I try to find the doc of template object (created by createTemplate()).
Is there a list of functions/members of template object?
