Displaying and processing HTML forms correctly in PHP can be a headache. You need to pay attention to printing context-sensitive error messages, preserving default values, properly encoding user input, and validating many different kinds of fields. The PEAR package HTML_QuickForm removes that headache. It's flexible architecture makes it a breeze to programmatically construct, display, and validate HTML forms of any size.

This session shows you how to harness the power of HTML_QuickForm in your PHP programs. It explains:

  • Working with different element types
  • Validating input with built-in and custom rules
  • Processing submitted form data, including file uploads
  • Customizing form display with the default renderer
  • Customizing form display with an external template engine
  • With HTML_QuickForm, a form is a logical collection of typed form elements instead of an undifferentiated blob of HTML. This makes it simple to decide dynamically what elements go in a particular form, to assign appropriate error messages and validation rules to individual elements, and to control the form layout in a systematic way across an entire site.

    Instead of relying on ad-hoc functions and methods for tasks like checking whether required form fields are filled in, preserving a default value in a dropdown menu, or adjusting the style attributes of form elements, use HTML_QuickForm for a simple, structured approach to form management.
