Sample SMS application
Last update:
Jun 9, 2026
The following CFC implements a simple employee phone directory lookup application. The user sends a message containing some part of the name being looked up (a space requests all names). The onIncomingMessage response depends on the number matches.
- If no match exists, the onIncomingMessage function returns a message indicating that no matches exist.
- If one match exists, the function returns the name, department, and phone number.
- If up to ten matches exist, the function returns a list of the names preceded by a number that the user can enter to get the detailed information.
- If over ten matches exist, the function returns a list of only the first ten names. A more complex application could let the user get multiple lists of messages to provide access to all names.
- If the user enters a number, and previously got a multiple-match list, the application returns the information for the name that corresponds to the number.
The following listing shows the CFC code:
<cfcomponent>
<cffunction name="onIncomingMessage">
<cfargument name="CFEvent" type="struct" required="YES">
<!--- Remove any extra white space from the message. --->
<cfset message =Trim(arguments.CFEvent.data.MESSAGE)>
<!--- If the message is numeric, a previous search probably returned a
list of names. Get the name to search for from the name list stored in
the Session scope. --->
<cfif isNumeric(message)>
<cfscript>
if (structKeyExists(session.users, val(message))) {
message = session.users[val(message)];
}
</cfscript>
