Loading view outside view folder with CodeIgniter

Don't know whether it's a correct way, but it works :)

In your application/core folder put this loader extention

<?php

class MY_Loader extends CI_Loader {

  function ext_view($folder, $view, $vars = array(), $return = FALSE) {
    $this->_ci_view_paths = array_merge($this->_ci_view_paths, array(APPPATH . $folder . '/' => TRUE));
    return $this->_ci_load(array(
                '_ci_view' => $view,
                '_ci_vars' => $this->_ci_object_to_array($vars),
                '_ci_return' => $return
            ));
  }

}

?>

Then you want a external view file, suppose its in the third_party folder

application/third_party/my_new_view.php

Hello : <?php echo $my_name; ?>

Then call your new view in the controller

ext_view is your new view loader method,

  • 1st param : the folder inside you applicaton
  • 2nd param : the view name
  • 3rd param : the variables data and so on...

test_controller.php

$view_data = array('my_name' => 'dino');
$this->load->ext_view('third_party', 'my_new_view', $view_data);

If everything fine. it will output

Hello : dino


Dino's solution seems very sound, and did indeed work for files in application, however, I was needing a bit deeper solution. Our CI is embedded into a subdirectory of a main directory, something like ip.ip.ip.ip/dir/sub/application/... Perhaps I was doing something wrong, but I was unable to make his solution work at all with my needs, even after trying to apply something like ../../, which still wouldn't be feasible; what if I need to go deeper into an unknown back directory count?

Thus I ended up writing my own solution, that thus far, seems to work great, tho it makes use of vanilla PHP. In this manner it seeks to grab the very base directory your files sit in and load them, pretty much the same way CI's load function works.

Same as his solution, create a file in application/core named MY_Loader.php. Then simply write in the following (or just add the method if you want to keep his solution as well):

<?php
    class MY_Loader extends CI_Loader {
        public function base_view($view, $vars = array(), $get = FALSE) {
            //  ensures leading /
            if ($view[0] != '/') $view = '/' . $view;
            //  ensures extension   
            $view .= ((strpos($view, ".", strlen($view)-5) === FALSE) ? '.php' : '');
            //  replaces \'s with /'s
            $view = str_replace('\\', '/', $view);

            if (!is_file($view)) if (is_file($_SERVER['DOCUMENT_ROOT'].$view)) $view = ($_SERVER['DOCUMENT_ROOT'].$view);

            if (is_file($view)) {
                if (!empty($vars)) extract($vars);
                ob_start();
                include($view);
                $return = ob_get_clean();
                if (!$get) echo($return);
                return $return;
            }

            return show_404($view);
        }
    }

Then, if you have a file named 'bob.php' in your inner most root directory, simply call as:

$this->load->base_view('bob');
// OR
$this->load->base_view('bob.php');
// OR if it's extension is .html
$this->load->base_view('bob.html');

And if it's in another directory at base root:

$this->load->base_view('directory/bob');
// OR
$this->load->base_view('directory\bob.htm');

Or however you please, as long as you call for a real file in a real directory!

Hope this alternate solution might help someone of similar peril.
