How to include helpers in smarty?

Id like to use static functions from helpers in a smarty template. 开发者_开发百科Im using ko3 and kohana-module-smarty - https://github.com/MrAnchovy/kohana-module-smarty/ so my question is how to autoload helper and use it in a template, ie:

app/class/url.php

class url {

function test () {

return 'test';

}

}

views/index.tpl

{$url.test}

You should be able to pass Url as a variable, $url, and access it within your view with {$url->test()}. I'm not sure if you would be able to access static functions like Url::test() though.

If you're using a helper in the same views, you can create a new controller that binds the variable in the view:

<?php
// application/classes/controller/site.php
class Controller_Site extends Controller_Template
{
    public $template = 'smarty:my_template';

    public function before()
    {
        $this->template->set_global('url_helper', new Url);
    }
}
?>

Then extend it in your other controllers:

<?php
// application/classes/controller/welcome.php
class Controller_Welcome extends Controller_Site
{
    public function action_index()
    {
        $this->template->content = 'Yada, yada, yada...';
    }
}

And access it within your views:

{* application/views/my_template.tpl *}
<p>This is a {$url_helper->test()}.</p>
<p>{$content}</p>
