Chapter 9: Handling Complex Data with Structures
Structure Example
Structures are particularly useful for grouping together a set of variables under a single
name. In the following example files, structures are used to collect information from a
form,
structinsert.cfm
addemployee.cfm
These example files show how you can use a structure to pass information to a custom
tag, named CF_ADDEMPLOYEE.
Example file structinsert.cfm

function. It calls the CF_ADDEMPLOYEE custom tag,

<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 all form fields are passed, create structure

<CFIF #FORM.FIRSTNAME# EQ "">

<CFOUTPUT>
<CFSCRIPT>
employee=StructNew();
StructInsert(employee, "firstname", "#FORM.firstname#");
