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

Record and field access


A common source of confusion for a Visualforce developer is configuring a Force.com site to allow unauthenticated access to Salesforce records and specific fields. This is usually configured via the Profiles menu located at Your Name | Setup | Administration Setup | Profiles. However, access to records and fields for a Force.com site is configured via the setup page for the site in question.

In this recipe, we will configure the Force.com site created in the first recipe to allow public access to contact records. We will then create a Visualforce page that allows a visitor to enter an e-mail address into a form on the Force.com site and extract the contact record matching the e-mail address, displaying the First Name, Last Name, and Email fields from the contact record.

Getting ready

This recipe requires that you have already completed the Creating a Site recipe, as it relies on the custom domain and Force.com site created in that recipe.
