 Posted: Mon Oct 19, 2009 7:25 pm Post subject: Caching problem |
 |
|
Hi,
After all, everything is Ok with my script. 
But I need to improve it. I'm caching some data of Twitter API, with a cache_lifetime of 3600 seconds (1 hour). Occasionally, the connection with Twitter timed out and I end up writing to cache incomplete information. 
What I need: a way to ignoring caching when assigned data is not as expected. But I don't know what logic I need to use. 
Thanks in advance,

I workarounded this problem in a not very elegant way :
| Code: | public function fetch() // it's the method that I use to get cache contents within my own class
{
// If locked, clear cache
if ($this->_isLocked()) {
$this->clearCache(); // this calls Smarty clear_cache() method and delete .lock file related
}
// No cache available
if (!$this->_smarty->is_cached($this->_template_file)) {
$data = $this->_getData(); // here I get Twitter API data
$this->_smarty->assign('widget_data', $data);
// Lock
if (!$data) {
$this->_createLockFile();
}
}
return $this->_smarty->fetch($this->_template_file);
} |
Does anyone have any better suggestions? 
Thanks in advance,
