Codeigniter functions in Smarty - codeigniter

Question

Im try use base_url() and site_url() from a Smarty template.
I read, some articles, about how do this. But, none works.
I create a "plugin" for Smarty called functions.url.php following this tutorial:
https://github.com/EllisLab/CodeIgniter/wiki/Smarty-plugin---URL-Helper
So, i use the {url} Smarty "tag":
<form action={url type='site' url='authentication/login'} method="post" id="login_form">
But, whe i access to the site, smarty shows a large Fatal Error in the below line:
'SmartyCompilerException' with message 'Syntax Error in template
Any ideas ?.
Edit: New steps.
I changed the name of plugin for: plugin.url.php And i try register the plugin in the controller with:
$this->smartyci->registerPlugin("function", "url", "smarty_function_url");
But a new error show:
'SmartyException' with message 'Plugin not callable'

Put Smarty to CI in some folder, for example, third_party/smarty.
Add Smarty to CI - create library application/libraries/Mysmarty.php
define('SMARTY_DIR', APPPATH . 'third_party/smarty/');
require_once(SMARTY_DIR.'Smarty.class.php');
class Mysmarty extends Smarty
{
public function __construct ( )
{
parent::__construct();
$config =& get_config();
$this->template_dir = $config['smarty_template_dir'];
$this->compile_dir = $config['smarty_compile_dir'];
$this->cache_dir = $config['cache_dir'];
$this->caching = $config['caching'];
}
function view($resource_name, $params = array()) {
if (strpos($resource_name, '.') === false) {
$resource_name .= '.tpl';
}
if (is_array($params) && count($params)) {
foreach ($params as $key => $value) {
$this->assign($key, $value);
}
}
if (!is_file($this->template_dir . $resource_name)) {
show_error("template: [$resource_name] cannot be found.");
}
return parent::display($resource_name);
}
}
Add new config variables to application/config/config.php
$config['smarty_template_dir'] = APPPATH . 'views/'; // folder for your smarty templates
$config['smarty_compile_dir'] = APPPATH . 'cache/smarty/compiled/'; // create this folder
$config['cache_dir'] = APPPATH . 'cache/smarty/cached/'; // create this folder
$config['caching'] = 0;
Add new library to autoload in file application/config/autoload.php
$autoload['libraries'] = array('database', 'session', 'mysmarty');
Now in your controller try to add some variable to smarty:
$this->mysmarty->assign('url', $this->config->item('base_url'));
and then show your template:
$this->mysmarty->view('main'); // template path is application/views/main.tpl
And in main.tpl add your form
<form action={$url} method="post" id="login_form">
