Form-based user input with Catalyst

With Catalyst, you can simply use HTML form input elements directly, or you can use a form framework plugin to make things easier:

• filter input -e.g. remove leading/trailing spaces, non-digits from credit card numbers
• validate input - e.g. make sure that the "e-mail" field does contain an e-mail
• highlight fields with errors after form submission, and keep the previously entered values when the application presents the form to the user for correction
• or even map database values to fields easily, for both loading and saving of data to/from forms

Form frameworks

• FormFu
• HTML::FormHandler - Moose based Form Processor. See history and differences from FormFu.
• Reaction - bleeding edge, better design than FormFu, more complex widget framework, experimental
• HTML::Widget - superseded by FormFu
• Rose::HTML::Objects - Rose::Object-based form management
• FormBuilder - old, use FormFu or FormHandler instead
