If you can code OpenCart modules, you can customize OpenCart and make e-commerce sites easier to administer and also change the way the default OpenCart system works. This book shows you how to create all sorts of extensions: OpenCart module, Order Total module, ideas for creating payment, shipping modules, and ways to create custom pages and forms on OpenCart module to carry out the insert, edit, delete, and list functions.
This book focuses on teaching you all aspects of OpenCart modules by showing and defining code examples. The book uses default OpenCart module to clone other modules, the process by which one module gets transferred to another. It shows each and every line of code and describes them so readers know what the code does. You will clone the Google_talk module in the first chapter. In the second chapter, you will learn about all the available methods in OpenCart, and at last you will create two custom module feedback pages and the Tips Order Total modules.
Each chapter teaches you to make a new OpenCart module; you will thus be able to make three modules by reading this book. You will be able to create the Hello World module by cloning the Google talk module that you can then change to the Welcome Message module. Likewise, you will get a description of each code of default featured module of OpenCart, and then create the Feedback pages to manage the feedbacks. In the end, you will be able to create an Order Total module called Tips Order Total module.
Each chapter builds a practical module from the ground up using step-by-step instructions and examples.
Chapter 1, Getting Started with OpenCart Module, shows us how to clone the Google_talk module to the Hello World module and lists ways to install, configure, and uninstall the OpenCart module and show the structure of the file of admin and frontend.
Chapter 2, Describing The Code of Extensions, lists all global methods of OpenCart, shows you how to configure the feature module, describes the code of the feature module, shows the way to start the coding for the shipping module, and describes the payment module.
Chapter 3, Create Custom OpenCart Module, shows you how to create a feedback module and the Tips Order Total module. It also shows how code works and are managed.
OpenCart, along with knowledge of the backend and frontend of the software is needed for this book.
This book is for programmers working with OpenCart, who want to develop custom OpenCart modules. You need to be familiar with the basics of OpenCart and PHP programming; after reading the book, you will be able to create customized OpenCart modules.
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: " As given at the controller, $group=helloworld, $data is $_POST, and $store_id is 0.."
A block of code is set as follows:
public function install($type, $code) {
$this->db->query("INSERT INTO " . DB_PREFIX ."extension SET `type` = '" . $this->db->escape($type) . "', `code` = '" . $this->db->escape($code) . "'");
}New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes, for example, appear in the text like this: " The file structure is divided into two sections admin and catalog".
