 Posted: Tue Jan 31, 2012 3:52 pm Post subject: Cashing included tpl in targeted file |
 |
|
hi. i am trying to figure out how smarty caching work. i have a target template store.tpl which has included tpl files in it. How can you go about caching included tpl files in targeted template. so far only caching targeted tpl. SO far smarty only caches one tpl file and wont let it load another one.
Below is partial of my code..
| Code: |
******application.php*********
<?php
// Reference Smarty library
require_once SMARTY_DIR . 'Smarty.class.php';
class Application extends Smarty
{
// Class constructor
public function __construct()
{
// Call Smarty's constructor
parent::Smarty();
// Change the default template directories
$this->template_dir = TEMPLATE_DIR;
$this->compile_dir = COMPILE_DIR;
$this->config_dir = CONFIG_DIR;
$this->plugins_dir[0] = SMARTY_DIR . 'plugins';
$this->plugins_dir[1] = PRESENTATION_DIR . 'smarty_plugins';
$this->cache_dir = CACHE_DIR;
$this->caching = 1;
$this->compile_check = TRUE;
$expiration_secs = 2 * 60 * 60;
$this->clear_all_cache($expiration_secs);
}
}
?>
*******Index.php************
<?php
require_once 'application.php';
// Load Smarty template file
$application = new Application();
// Display the page
$application->display('store.tpl');
?>
*****store.tpl***********
{load_presentation_object filename="store" assign="obj"}
{include file="header.tpl"}
{include file="body.tpl"}
{include file="another.tpl"}
{$obj->mContentsCell}
******store.php**********
<?php
class Store
{
//defined some varibles
// Class constructor
public function __construct()
{
//some code here
}
// Initialize presentation object
public function init()
{
// Load department details if visiting a main
if (isset ($_GET['DepartmentId']))
{
$this->mContentsCell = 'department_no_col.tpl';
}
elseif (another condition)
{
$this->mContentsCell = 'product.tpl';
}
}
?>
******smarty plugin that loads objects from class******
<?php
// Plug-in functions inside plug-in files must be named: smarty_type_name
function smarty_function_load_presentation_object($params, $smarty)
{
require_once PRESENTATION_DIR . $params['filename'] . '.php';
$className = str_replace(' ', '',
ucfirst(str_replace('_', ' ',
$params['filename'])));
// Create presentation object
$obj = new $className();
if (method_exists($obj, 'init'))
{
$obj->init();
}
// Assign template variable
$smarty->assign($params['assign'], $obj);
}
?> |

If you enable caching and call display('store.tpl') the complete output including the subtemplate is cached.
There is no need to call $this->clear_all_cache($expiration_secs);
to delete outdated cache files.
Just define your life time like
$this->cache_lifetime = 2 * 60 * 60;
and Smarty will refresh the cache automatically if this time has expired. |
