And to make it complete, my last update.. :).
You would want to put LoadModel inside the if that checks if the cache is
still existing.
Otherwise it just adds overhead, and their is no point in using the cache.
This is the code:
<?php
class AppController extends Controller {
function beforeFilter() {
$this->pfSettings = $this->getSettings();
$this->fillLayout();
}
function fillLayout()
{
$this->set('site_name', $this->pfSettings['name']);
$this->set('site_title', $this->pfSettings['name']);
$this->set('site_description', $this->pfSettings['description']);
}
function getSettings()
{
//check to see if they are in the cache.
if (!$cachedSettings = Cache::read('settings')) {
//load settings model
$this->loadModel('Setting');
//find all in the settings database
if($settings = $this->Setting->find('all')) {
$configurations = array();
foreach ($settings as $setting):
$configurations[$setting['Setting']['key']] =
$setting['Setting']['value'];
endforeach;
Cache::write('settings', $configurations);
return $configurations;
}
else
{
//TODO: set error that settings failed
exit();
}
} else {
//return the cached settings.
return $cachedSettings;
}
}
}
