X2Form: Show and validate HTML forms defined in XML files

This package can display and validate HTML forms defined in XML files.

It can add the definitions of a form with specific calls to the main forms class or it can parse a given XML file with the definitions of the elements of a form.

The parameter values of some types of form elements can be retrieved from a MySQL database.

The forms class can call a form elements class that is responsible for rendering the individual form elements.

The form output layout can be defined using separate HTML template files.

The main forms class can also change the default values of the inputs, as well perform validation of the submitted form input values.

It can also process uploaded files moving them to a destination directory eventually overwriting previously uploaded files.
