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.

Creating a website template


In the previous recipes in this chapter, each page contained the entire Visualforce markup needed to display its content. This leads to repetition of common markup, to display headers and footers for example. In the event that the header or footer content needs to be changed, every page on a site needs to be updated with the new markup.

Visualforce provides a solution to this issue-templates. These allow the common elements of a site to be added to a template that is used as the starting point for rendering any page. The page then injects its specific content into the template at appropriate points.

In this recipe we will create a template version of the SiteItem Visualforce page from the Retrieving content from Salesforce recipe, where the template provides the header and footer markup. We will then make this page publicly available via an unauthenticated Force.com site.
