- <!--- This example shows how to use the StructKeyArray
- function to copy the keys from a specified structure to an array.
- It also uses the StructNew function to create the structure
- and fills its fields with the information the user types
- into the corresponding form fields. --->

- <!--- This section of code creates the new structure and checks to
- see if the submit button has been pressed. If it has been
- pressed, the code defines fields in the employee structure
- with what the user has entered from the form. --->
- <CFSET employee=StructNew()>
- <CFIF Isdefined("Form.Submit")>
- <CFIF Form.Submit is "OK">
- <CFSET employee.firstname = FORM.firstname>
- <CFSET employee.lastname = FORM.lastname>
- <CFSET employee.email = FORM.email>
- <CFSET employee.phone = FORM.phone>
- <CFSET employee.company = FORM.company>

- This example uses the StructNew function to create a structure
- that supplies employee information. The data structure is called
- "employee" and its fields are filled with the contents of the
- following form. After you have entered employee information into the
- structure, the example uses the <b>StructKeyArray</b> function to copy
- all of the keys from the structure into an array.
