Consistently ranked in the top 15 of the most installed Drupal contributed modules (see http://www.drupal.org/project/usage), Webform has proven to be a must-have extension on Drupal websites the world over. There is simply no better way to rapidly create forms on our Drupal websites.
After taking an in-depth look at working with Webform components and submitted data, we delve into enhancing our forms with some programming exercises that introduce the Webform API. Of course, no Drupal module is an island, so we cover several of the contributed modules that extend Webform to add value to our forms and the way they are experienced.
Chapter 1, Setting up Webform, explains how to install the Webform module and covers a brief discussion of the Webform configuration options.
Chapter 2, Trying Out Webform, introduces Webform components, building, and testing our first Webform module.
Chapter 3, Working with Submissions, covers the Webform backend and explains how to work with data submitted to our form.
Chapter 4, Discovering More Components, continues the exploration of available Webform components.
Chapter 5, Tweaking the Form Settings, covers how to customize our form’s user interface and feedback to respondents.
Chapter 6, Extending Webform, discovers additional modules to enhance the user experience of our form, protecting our forms with CAPTCHA, and an introduction to the Webform API.
Chapter 7, Theming Webform, explains how to make use of the Drupal theming layer to give our form a look and feel all of its own.
Chapter 8, Acting on Webform Submissions, creates custom modules that interact with user submitted data, adding custom validation rules.
Chapter 9, Creating Webform Components, explains how to build our own custom Webform component from the ground up.
Chapter 10, Creating Submission Actions, discusses carrying out multiple actions with a single click.
Chapter 11, Presenting and Managing Data, explains how to make use of extra modules to produce customized submitted data listings and covers how to keep track of changes made to submitted data.
Chapter 12, Going Out of the Box, discusses displaying and hiding fields based on previous input, validating input data on the client side, and importing submissions.
To follow along with the exercises and discussions in this book, you will need a working Drupal 7 installation and access to the Internet. Your Drupal installation may be remote (that is, hosted on a web server) or, preferably, a local installation on your PC or laptop.
Some experience with the PHP programming language is recommended before tackling the programming exercises, but this is not an outright requirement as the code samples have been thoroughly tested. The programming tasks covered within this book can be coded with any standard plain text editor, although a programming editor is advised.
Written as a guide for Internet users and developers alike, Drupal 7 Webform Cookbook gives you the tools needed to turn your Drupal website into an information-gathering superhighway. Basic knowledge of Drupal is required.
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: “ This is to ensure that the %useremail token substitution works as expected.”
A block of code is set as follows:
name = Webform Custom description = Customize Webform Results page. core = 7.x package = Webform dependencies[] = webform
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
name = Webform Custom
description = Customize Webform Results page.
core = 7.x
package = Webform
dependencies[] = webform
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 Submit button is universally understood as it appears on a majority of forms on the Internet.”
