Passing Data Using Forms
Another
method for passing data from template to template involves sending
the data via the HTTP Post method as form-field data. When you create
an HTML form that posts to another ColdFusion template, each form

FORM tag. Within the receiving template, each form

ContactForm.cfm template, shown in Example 3-6, creates a simple HTML form that collects
basic contact information and posts it to the
DisplayContactInfo.cfm template, shown in Example 3-7.
