If PrestaShop is based on a 3-tier architecture (MVC), what is the name of the controller that renders the .tpl files inside a theme? e.g myProject/themes/default("Default theme in Prestashop")/(.tpl files) or maybe where I can find the location of the controller that renders the .tpl files? So that I can add more smarty tags //Assume this file is the controller that renders the .tpl files in a theme //I got this code for converting a php value to a smarty tag in creating a module http://doc.prestashop.com/display/PS15/Creating+a+PrestaShop+module $this->context->smarty->assign(array( 'Hello' => "Hello", 'World' => "World", 'another_smarty_tag' => "Im another smarty tag" ));
