 Posted: Tue Mar 21, 2017 2:59 pm Post subject: Smarty 3.1.30 and MemCached |
 |
|
Hey Smarty Team,
we are currently using Smarty 3.1.30 and make heavy use of Caching. We have thousands of files organised in CacheGroups like:
| Quote: | | www.tourispo.com|desktop|site|sections|desktop|loggedout|css| |
We were moving all our caching into MemCached which worked great with all ZendFramework Caching, however I badly failed using MemCached with Smarty cache. First of all in that file: https://github.com/smarty-php/smarty/blob/master/demo/plugins/cacheresource.memcache.php ...
there is a line of code:
| Code: | | $res = $this->memcache->get($_keys); |
However this only works in Memcache not in Memcached (see the d at the end). It fails with | Quote: | | Memcached::get() expects parameter 1 to be string, array given |
as Memcached::get() expects a string as a key and not an array. Please note that Memcache::get() (Memcache WITHOUT the d) can use both string and key. I could fix this by replacing the line with...
| Code: | | $res = $this->memcache->getMulti($_keys); |
However if done, I get the following error message on the first page load (empty cache):
| Quote: | | Fatal error: Uncaught --> Smarty: Invalid compiled template for '/var/www/sgtest/htdocs/templates/desktop/sections/frame/headerStart.tpl |
My question would be if anyone has ever succeeded using Memcached (not Memcache) with Smarty. If yes is there a plugin that also handles clearing groups of CacheGroups (i.e. clear all templates in www.tourispo.com|desktop|site|sections|...). I think that is all missing for the current CacheHandler linked in the file above.
Thanks for all comments and help

Hello AnrDaemon,
thanks for your quick reply. The solution you just posted is not a plugin but a class which extends Smarty. This is not what I meant as it does not only override caching but also whole methods like fetch():
| Quote: | ...instead of calling the Smarty fetch() class function, you
now call $smarty->Memcached_fetch($key, $tpl, $ttl)... |
I think I could really implement this plugin with maybe some guidance. What I don't get is why I get the:
| Code: |
Fatal error: Uncaught --> Smarty: Invalid compiled template for '/var/www/sgtest/htdocs/templates/desktop/sections/frame/headerStart.tpl
|
On first page load.. There shouldn't be any cached file anyways due to an empty cache....[/code] |

UPDATE: The same happens when I use Memcache (without the d) for which there is already a suggested custom Cache implementation at: http://www.smarty.net/docs/en/caching.custom.tpl called Smarty_CacheResource_Memcache
As soon as I switch to this implementation I get:
| Quote: |
Fatal error: Uncaught --> Smarty: Invalid compiled template for '/var/www/sgtest/htdocs/templates/desktop/sections/frame/headerStart.tpl |
Switching to file based caching works perfectly. Isn't this CacheResource on official Smarty page supposed to work??
Thanks
