Visualforce Development Cookbook - Second Edition

By: Keir Bowden

Overview of this book

Visualforce is a framework that allows developers to build sophisticated, custom user interfaces that can be hosted natively on the Force.com platform. The Visualforce framework includes a tag-based markup language, similar to HTML that is used to write the Visualforce pages and a set of controllers that are used to write business logic to the Visualforce pages. Visualforce Development Cookbook provides solutions to a variety of challenges faced by Salesforce developers and demonstrates how easy it is to build rich, interactive pages using Visualforce. Whether you are looking to make a minor addition to the standard page functionality or override it completely, this book will provide you with the help you require throughout. You will start by learning about the simple utilities and will build up to more advanced techniques for data visualization and to reuse functionality. You will learn how to perform various tasks such as creating multiple records from a single page, visualizing data as charts, using JavaScript to enhance client-side functionality, building a public website, and making data available to a mobile device. With an interesting chapter on tackling common issues faced while developing Visualforce pages, the book provides lots of practical examples to enhance and extend your Salesforce user interface.

Preface

Scanning the QR code to access the record


Mobile devices, especially phones, have small keyboards and screens which can make entering page URLs difficult. If the device has a camera, scanning a code to navigate to a page can improve the user experience.

QR, or Quick Response, codes are two-dimensional barcodes originally used to track automobiles during manufacture. For more information on QR codes, refer to the following link: http://www.qrcode.com/en/history/.

In this recipe, we will create a Visualforce page to display the QR code of an opportunity. When the code is scanned on a mobile device, this navigates the user to the Salesforce1 record home page to allow them to view the opportunity details.

Getting ready

This recipe relies on the mobile device being able to scan the QR code with a custom URL scheme - a free application that provides this capability in iOS is Qrafter, available from the link given as: https://itunes.apple.com/gb/app/qrafter-qr-code-barcode-reader/id416098700?mt=8...
