This book is the missing manual for creating forms on your Joomla! site. Using simple examples that you can easily follow we will show you how you can create forms of almost any kind. Most of the chapters focus on one topic starting with simple recipes for new users and then adding new features that add more to the form but may also require more knowledge and experience to implement.Other chapters look in more detail at adding special features, or creating forms to perform particular tasks. Again the recipes range from those that a new user can easily implement to those that will help more advanced developers.Each recipe is kept as simple as possible and set out so that it can be easily implemented with the code supplied; and the recipes are also a set of building blocks that you can use to create much more complex forms using several recipes to build your form.As far as space allows we have explained how the code works, what features of Joomla or of ChronoForms we are using and we’ve offered suggestions in the ‘There’s more . . .’ sections for ways in which the basic recipe can be extended or adapted.The code examples are complete and can be adapted by new users with the minimum of customization or they can be as a starting point for developers with more coding experience to build on and adapt to create fully customized form applications.
