layouts?

[eluser]Unknown[/eluser]
I have a shorter updated version:

Code:

<?php


/**
* Yield  ::  HOOKS
*
* Adds layout support :: Similar to RoR <%= yield =>
* '{yield}' will be replaced with all output generated by the controller/view.
*/
class Yield
{
    function doYield()
    {
        
        global $OUT;

        $CI =& get_instance();
        $view = $output = $CI->output->get_output();
        $default = APPPATH.'views/layouts/default.php';
        $layout = (isset($CI->layout))?$CI->layout:'default';

        if ($layout !== false){
            $layout .= (!preg_match('/(.+).php$/', $layout))?'.php':'';
            $requested = APPPATH.'views/layouts/' . $layout;
            if (file_exists($requested)){
                $layout_output = $CI->load->file($requested, true);
                $view = str_replace("{yield}", $output, $layout_output);
            }
        }

        $OUT->_display($view);
    }
}
