Hi, i am working through Christian Daries PHP and Mysql Ecommerce chapter 4 and am receiving a Fatal Error.

Fatal error: Class 'Catalog' not found in C:\xampp\htdocs\myshop\presentation\departments_list.php on line 23

Can anyone please help me with this error?

Many thanks in advance.

Here is the code from the files associated and i have attached my file structure also.


// include utility files
require_once 'include/config.php';

// load the application page template
require_once PRESENTATION_DIR . 'application.php';

// load Smarty template file
$application = new Application();

// display the page

//load database handler script
require_once BUSINESS_DIR . 'database_handler.php';

//load business teir
require_once BUSINESS_DIR . 'catalog.php';



// Manages the departments list
class DepartmentsList
  /* Public variables available in departments_list.tpl Smarty template */
  public $mSelectedDepartment = 0;
  public $mDepartments;

  // Constructor reads query string parameter
  public function __construct()
    /* If DepartmentId exists in the query string, we're visiting a
       department */
    if (isset ($_GET['DepartmentId']))
      $this->mSelectedDepartment = (int)$_GET['DepartmentId'];

  /* Calls business tier method to read departments list and create
     their links */
  public function init()
    // Get the list of departments from the business tier
    $this->mDepartments = Catalog::GetDepartments();

    // Create the department links
    for ($i = 0; $i < count($this->mDepartments); $i++)
      $this->mDepartments[$i]['link_to_department'] =


// Business tier class for reading product catalog information

class Catalog
  // Retrieves all departments
  public static function GetDepartments()
    // Build SQL query
    $sql = 'CALL catalog_get_departments_list()';

    // Execute the query and return the results
    return DatabaseHandler::GetAll($sql);

The catalog file is not included at the time of the call. Make sure it is.

Thankyou for your reply.

Sorry about being dumb,

but how would i do this as i thought it was being called when index.php runs at:

require_once BUSINESS_DIR . 'catalog.php';

many thanks


try inserting the inclusion in department_list.php:
// Manages the departments list
class DepartmentsList
