The Creating Forms chapter of the ATG Page Developer's Guide describes how you can link form elements in JavaServer Pages with the properties of Nucleus components. The tools described in that chapter are useful for simple form processing. In some cases, though, you may find that your applications require more sophisticated tools for working with forms.
This chapter discusses tools you can use and extend for more complex form processing. These tools include:
form handlers, which you can use to evaluate the validity of form data before it is submitted, write data to and read data from a database or repository, and direct the user to different pages, depending on the results of the form submission
tag converters, which enable your application to parse and display form data in a number of formats
form elements that enable users to upload files
This chapter includes the following sections:
Form Handlers and Handler Methods
Explains how to create form handlers and handler methods for processing forms.
Creating Custom Tag Converters
Explains how to use tag converters in forms to parse and display values in a variety of formats.
File Uploading
Describes how to create form elements and components that enable users to upload files to a site.
