Structure example
Structures are particularly useful for grouping together a set of variables under a single name. The
example in this section uses structures to collect information from a form, and to submit that
information to a custom tag, named
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
<html>
<head>
<title>Add New Employees</title>
</head>
<body>
<h1>Add New Employees</h1>
<!--- Action page code for the form at the bottom of this page --->
<!--- Establish parameters for first time through --->
<cfparam name="Form.firstname" default="">
<cfparam name="Form.lastname" default="">
<cfparam name="Form.email" default="">
<cfparam name="Form.phone" default="">
<cfparam name="Form.department" default="">
<!--- If at least the firstname form field is passed, create
a structure named employee and add values --->
<cfif #Form.firstname# eq "">
<p>Please fill out the form.</p>
<cfelse>
<cfoutput>
<cfscript>
employee=StructNew();
employee.firstname = Form.firstname;
employee.lastname = Form.lastname;
employee.email = Form.email;
employee.phone = Form.phone;
employee.department = Form.department;
</cfscript>
<!--- Display results of creating the structure --->
First name is #StructFind(employee, "firstname")#<br>
Last name is #StructFind(employee, "lastname")#<br>
EMail is #StructFind(employee, "email")#<br>
Phone is #StructFind(employee, "phone")#<br>
Department is #StructFind(employee, "department")#<br>
</cfoutput>
<!--- Call the custom tag that adds employees --->
<cf_addemployee empinfo="#employee#">
</cfif>
<!--- The form for adding the new employee information --->
