How do I load a view from outside the default views folder in this application? - Ajax30 - 10-28-2020

I am working on a CMS with [b]CodeIgniter 3.1.8[/b] and Bootstrap 4. I have decided to add themes to it.

The [i]themes[/i] directory is outside [i]application[/i] as can be see in the image below:
[color=var(--blue-700)] [Image: syL0A.jpg]

Inside [i]themes[/i] I have the theme directory (of course) which contains the "master view", layout.php:
[/color][color=var(--blue-700)] [Image: gOGzZ.jpg]

In application/core [/color]I have added a Loader.php file with the following contents:

Code:
<?php defined('BASEPATH') OR exit('No direct script access allowed');

require APPPATH."../system/core/Loader.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' => $this->_ci_prepare_view_vars($vars),

                '_ci_return' => $return

            ));

      }

}?>

In my Posts controller's index() method, I load the view passing it the data:

Code:
public function index() {

    //more code here

     $this->load->ext_view('third_party', 'themes/caminar/layout', $data);

}

I get this error message:

Code:
Call to undefined method CI_Loader::ext_view()

[b]NOTE:[/b] the application is [b]not HMVC[/b], only MVC.

What am I doing wrong?

This is not tested.

Add this to index.php

PHP Code:
$theme_path = 'themes';

if (($_temp = realpath($theme_path)) !== FALSE)
{
    $theme_path = $_temp.DIRECTORY_SEPARATOR;
}
else
{
    // Ensure there's a trailing slash
    $theme_path = strtr(
        rtrim($theme_path, '/\\'),
            '/\\',
        DIRECTORY_SEPARATOR.DIRECTORY_SEPARATOR
    ).DIRECTORY_SEPARATOR;
}

// Path to the themes directory
define('THEMEPATH', $theme_path); 

The your code would be something like this.

PHP Code:
<?php

// application/core
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(THEMEPATH . $folder . '/' => TRUE));
        return $this->_ci_load(array(
            '_ci_view' => $view,
            '_ci_vars' => $this->_ci_object_to_array($vars),
            '_ci_return' => $return
        ));
    }
}

$view_data = array('my_name' => 'dino');

// you may need to create a folder for the layout using this.
$this->load->ext_view('view_folder', 'my_new_view', $view_data); 

Give that a try.

Thanks!

I solved it. Have a look here if you're curios.
