} ?> [/code] [h3]Usage[/h3] [h4]Loading the library[/h4] You can use it in two ways. First and obvious is to place the following line in the controller's constructor function. [code]$this->load->library('layout', 'layout_main');[/code] The second is by enabling codeIgniter to autoload the library by editing [b]/application/config/autoload.php[/b][code]$autoload['libraries'] = array('layout');[/code]After you do either of the above, and the library is loaded, in your controller you may do this: [code]$this->layout->view('/shop/view_cart', $data);[/code] [h4]Master layout[/h2] [b]/application/views/layout_main.php[/b] Your view file must use $content_for_layout. For example:[code]<html> <head> <title><?=$title_for_layout?></title> <meta http-equiv="content-type" content="text/html;charset=utf-8" /> <link rel="stylesheet" href="/css/main.css" type="text/css" /> </head> <body>
