Well, this is what I have done to use Smarty according to tutorials.
Downloaded the Smarty to app/ThirdParty/Smarty and created following folders: writable/smarty/templates_c and
writable/smarty/cache
app/Libraries/CI4Smarty.php:
Code:
namespace App\Libraries;
require_once APPPATH.'ThirdParty/Smarty/Autoloader.php';
use \Smarty_Autoloader;
Smarty_Autoloader::register();
use \Smarty;
class CI4Smarty extends Smarty {
public function __construct()
{
parent::__construct();
parent::setTemplateDir(APPPATH . 'Views/');
parent::setCompileDir(WRITEPATH . 'smarty/templates_c/')->setCacheDir(WRITEPATH . 'smarty/cache/');
}
public function view($tpl_name) {
if (substr($tpl_name, -4) != '.tpl'){
$tpl_name.='.tpl';
}
parent::display($tpl_name);
}
}
app/Config/Services.php:
Code:
namespace Config;
use CodeIgniter\Config\Services as CoreServices;
use CodeIgniter\Config\BaseConfig;
use Config\App;
use App\Libraries\CI4Smarty;
require_once SYSTEMPATH . 'Config/Services.php';
class Services extends CoreServices
{
public static function SmartyEngine($getShared = true){
return ($getShared === true ? static::getSharedInstance('SmartyEngine') : new CI4Smarty());
}
};
Controller to return function:
Code:
return service('SmartyEngine')->view('smarty_template.tpl');
This approach (service) avoids to load Smarty every time when your app runs. You can call service('SmartyEngine') in your controller whenever you need to run it.
