By default Tangra framework based sites use » Smarty as template engine (tple). To export value to the tple you can use page method export. Open /hidden/inc/pages/index_wp.class.php and add the following method:
public function run() {
$this->export('world_type', 'cruel');
return $this->get_view('default');
}
In your TPL file (/hidden/tpl/pages/en/index/index_default_en.tpl) change the text to:
Hello {$world_type} world!and hit refresh. You should see Hello cruel world!
