Structure examples
Structures are useful for grouping a set of variables under a single name. The following example uses structures to
collect information from a form, and to submit that information to a custom tag, named
information on creating and using custom tags, see
Example file newemployee.cfm
The following ColdFusion page shows how to create structures and use them to add data to a database. It calls the
custom tag, which is defined in the addemployee.cfm file.
