Comparing changes: https://github.com/smarty-php/smarty/compare/v4.3.1...v4.4.1 It is noticeable that Smarty 4.3.1 does not officially support PHP 8.3. Is only supported with 4.4.0. Remark: During tests with Smarty 4.5.1, it was noticed that the following warning occurs: Deprecated: Using the unregistered function "function_exists" in a template is deprecated and will be removed in a future version. Use Smarty::registerPlugin to explicitly register a custom modifier. As of Smarty 5.X.X, templates must be revised again. The Smarty release 5.0.2 is already officially available. However, integration into FlatPress is not entirely trivial.

\$cache\_lifetime {#variable.cache.lifetime}
|
|
=================
|
|
|
|
This is the length of time in seconds that a template cache is valid.
|
|
Once this time has expired, the cache will be regenerated.
|
|
|
|
- `$caching` must be turned on (either
|
|
Smarty::CACHING\_LIFETIME\_CURRENT or
|
|
Smarty::CACHING\_LIFETIME\_SAVED) for `$cache_lifetime` to have any
|
|
purpose.
|
|
|
|
- A `$cache_lifetime` value of -1 will force the cache to never
|
|
expire.
|
|
|
|
- A value of 0 will cause the cache to always regenerate (good for
|
|
testing only, to disable caching a more efficient method is to set
|
|
[`$caching`](#variable.caching) = Smarty::CACHING\_OFF).
|
|
|
|
- If you want to give certain templates their own cache lifetime, you
|
|
could do this by setting [`$caching`](#variable.caching) =
|
|
Smarty::CACHING\_LIFETIME\_SAVED, then set `$cache_lifetime` to a
|
|
unique value just before calling [`display()`](#api.display) or
|
|
[`fetch()`](#api.fetch).
|
|
|
|
If [`$force_compile`](#variable.force.compile) is enabled, the cache
|
|
files will be regenerated every time, effectively disabling caching. You
|
|
can clear all the cache files with the
|
|
[`clear_all_cache()`](#api.clear.all.cache) function, or individual
|
|
cache files (or groups) with the [`clear_cache()`](#api.clear.cache)
|
|
function.
