The following describes a few of the tasks you can perform with PDF forms:
cfpdfform - Reads data from a form and writes it to a file or populates a form with data from a data source.
cfpdfformparam - A child tag of the cfpdfform tag or the cfpdfsubform tag; populates individual fields in PDF forms.
cfpdfsubform - A child tag of the cfpdfform tag; creates the hierarchy of the PDF form so that form fields are filled properly.
The cfpdfsubform tag contains one or more cfpdpformparam tags.
