You should already have a sense of how forms work in the normal online world of desktop Web browsers. You create a form and associate it with an action; often a cgi-bin script of some sort. A user enters data into the form through text fields, check boxes, and so on. Using the M-Business Client capabilities, you also can create a form with fields prepopulated with a user’s e-mail address and zip code, and, if you feel like being clever, you can enter data for the user through hidden fields. Regardless of what elements are in the form, the data is passed on as parameters to the action associated with that form. The action will perform some sort of processing on the data received, and then outputs its results in the form of an HTML document.
