View Object PHP5

This is a totally PHP5 object oriented View library.

You can add a master template from which you can load View Objects as partials or you can use the View Object to render partials only. (ie: header, menu, content, sidebar, footer)

[size=2]Usage:[/size]

Load the View library from application/libraries. [code]

$this->load->library('view');

[/code]

Add a master layout (template) file [code]

$this->view->layout = 'master_layout_file'; // or leave this empty to render partials only

[/code]

Add data to the master template view [code]

$this->view->set($site->data);

[/code]

Add a partial file and (optional) $data [code]

$header = $this->view->load('header', 'header_file', $data);

[/code]

Partials are View objects too, so you can add partials to partials [code]

$header->load('sub_header', 'sub_header_file', $data);

[/code]

Add data to any partial [code]

$header->set($data);

[/code]

Render your View [code]

$this->view->render();

// using __toString()

echo $this->view

[/code]

Inside your master template [code]

<?php echo $header; ?>

[/code]
