• View Library

• Renders a layout with partials (blocks) inside.

• Renders partials only (header,content,footer. etc).

• Allows a plugin to render a partial.

• The source directory can be specified.

• Works with Matchbox modules.

• Version 2.1.0 Wiredesignz (c) 2008-02-18 **/ class View { var $layout, $data, $partials = array();

       'directory' => '',

Example using the View Object in a Controller: [code]

$this->load->library('view'); // or autoload

$this->view->layout = 'admin/layout';

$this->view->data(array( // set the view data 'privileges' => $privileges, 'catcode' => -1, // default value no category menu 'page' => $page,
));

$this->view->load(array( // load the page partials 'header' => 'header',
'menu' => 'menu', 'content' => 'admin/'.$page, 'footer' => 'footer', ));

$this->view->render();

[/code]
