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 might 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:
Form handlers 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 parse and display form data in a number of formats.
Form elements enable users to upload files.
