Winter MVC

Extra lightweight MVC library suitable for WordPress Plugins or other cases, inspired by CodeIgniter

How to integrate into WordPress Plugin?

To simplify development, make code structure naicer and easy to maintain we suggestint to use WP Boilerplate file structure: https://wppb.me/

Copy Winter_MVC folder into: wp-content\plugins{your-plugin-name}\vendor

Create application structure:

wp-content\plugins\{your-plugin-name}\application
wp-content\plugins\{your-plugin-name}\application\controllers
wp-content\plugins\{your-plugin-name}\application\core
wp-content\plugins\{your-plugin-name}\application\models
wp-content\plugins\{your-plugin-name}\application\views

In your plugin admin file, if you using wppb: wp-content\plugins{your-plugin-name}\admin\class-{your-plugin-name}-admin.php

Create method admin_page_display()

public function admin_page_display() {
  global $Winter_MVC;

  $page = '';
      $function = '';

  if(isset($_GET['page']))$page = wmvc_xss_clean($_GET['page']);
  if(isset($_GET['function']))$function = wmvc_xss_clean($_GET['function']);

  $Winter_MVC = new MVC_Loader(plugin_dir_path( __FILE__ ).'../');
  $Winter_MVC->load_helper('basic');
  $Winter_MVC->load_controller($page, $function, array());
}

this method you can call from wp menu this way:

add_submenu_page(..., array($this, 'admin_page_display'));

Based on page and funciton GET parameters, library will call specific controller file and method/function:

wp-content\plugins\{your-plugin-name}\application\controllers\{Your-plugin-name}.php

First character uppercase!

Create this controller file and class should look like:

<?php
defined('WINTER_MVC_PATH') OR exit('No direct script access allowed');

class {Your-plugin-name}_index extends Winter_MVC_Controller {

	public function __construct(){
		parent::__construct();
	}
    
	public function index()
	{
        // Your controller logic code cooming here
        
        // Load view
        $this->load->view('{your-plugin-name}/index', $this->data);
  }
	public function datatable()...

in this example we added _index in classname as example but have in mind that this is not required, but useful only if class {Your-plugin-name} already exists what is common if using wppb

Create also your view file:

wp-content\plugins\{your-plugin-name}\application\views\{your-plugin-name}\index.php
