Adding columns to your view

In our default list view that shows all our portfolio items in the backend, we currently only have a checkbox and the Title column, so we need to add a few more columns in here. We will concentrate on the company and id columns initially, and then add status and ordering columns which are a bit more complex.

Adding simple columns

The first thing we need to do is adjust our model so that it selects the data from the database table jos_folio that we want to display in this view. Edit the file /administrator/components/com_folio/models/folios.php, and add the highlighted code:

<?php
defined('_JEXEC') or die;
class FolioModelFolios extends JModelList
{
  public function __construct($config = array())
  {
    if (empty($config['filter_fields']))
    {
      $config['filter_fields'] = array(
        'id', 'a.id',
        'title', 'a.title',
        'state', 'a.state',
        'company', 'a.company'        
      );
    }
    parent::__construct($config);
  }
  protected...
