Overview

You may want to add additional pages to your Zen Cart™ store. Here are the basics steps you should follow. We will assume your new page is named myNewPage.

Components of the new page

In order for the Zen Cart™ system to pick up the new page, you will need to include four components:

• A new directory, includes/modules/pages/myNewPage/, containing a file called header_php.php

• A new file in the directory includes/templates/template_default/templates called tpl_myNewPage_default.php

• A new file, includes/extra_datafiles/myNewPage.php, defining your new page’s filename for the Zen Cart™ system

• A new language file, includes/languages/english/myNewPage.php

Naming your files

It’s important that all these new components use the same name for your new page. (The only partial exception is the extra_datafiles file; see below.) Be sure that your new pages directory name, language file name, and template file name use exactly the same name for your new page.

The header_php.php file

At a minimum, this file should contain the following:

<?php
//
// +----------------------------------------------------------------------+
// |zen-cart Open Source E-commerce                                       |

// | http://www.zen-cart.com/index.php                                    |
// |                                                                      |

// $Id: header_php.php $

  require(DIR_WS_MODULES . 'require_languages.php');
  $breadcrumb->add(NAVBAR_TITLE);
?>

Additionally, you can add in whatever processing you need to do on your page to this file. Have a look at the other pages in the includes/modules/pages/ directory to get an idea of what this file is for.

The template file

The new template file, includes/templates/template_default/templates/tpl_myNewPage_default.php, contains the main HTML body for your page. A good starting point for this page is to copy one of the other pages in this directory and adjust it to fit your new page’s desired format.

Custom templates

You can copy your new template page from template_default to a custom template directory if you’d like to make template-specific changes to the layout (for example, for a seasonal design).

The extra_datafiles file

This file, includes/extra_datafiles/myNewPage.php, should contain the following line:

<?php
define(FILENAME_MYNEWPAGE, 'myNewPage');
?>

The constant on the left, FILENAME_MYNEWPAGE, is the tag you will use to link to your new page from other locations in your shop. The string on the right, myNewPage, must exactly match the name of your new includes/modules/pages/ directory.

Just one new file

You don’t need a separate new extra_datafiles file for each new page you create. If you are adding several new pages, you can place all the filename defines into one file, and give that file any name whatsoever. All the files in the extra_datafiles folder are loaded in for every page.

The language file

The language file for your page should contain definitions for all the local text elements on your page; for example:

<?php
define('NAVBAR_TITLE', 'New Page');
define('HEADING_TITLE','My Cool New Page');
?>

Other languages
