RE: [CFCDev] Return values from a loop

[Cave, Phillip (Contractor)]

Hi Ben,

You are overwriting the eventTitle var with each iteration through the loop. So this 
function is only going to return the last value. A function should only return one 
value at a time (unless you return a complex var type). You can stick the values in an 
array or list and return that instead...

Subject: [CFCDev] Return values from a loop


I'm reading in an XML file and trying to output some of the data. If I
do a loop in the cfc and try to output it to a page I am only getting
one value returned instead of all 7. I'm guessing because my cfreturn is
outside of the loop but I can't seem to get it to display. The code in
my cfc looks like:

<cfcomponent>
        <cffunction access="public" name="readAll" output="false"
returntype="string">
                <cffile action="read"
file="C:\cfusionMX\wwwroot\SparkEventsCalendar_loadXml.xml"
variable="event">
        <cfset variables.calEvents = XmlParse(event)>
          <cfloop from="1"
to="#ArrayLen(variables.calEvents.events.XmlChildren)#"
index="evntTitle">
                  <cfset eventTitle =
variables.calEvents.events.event[evntTitle].XmlAttributes.title />
                  </cfloop>
                <cfreturn eventTitle />
        </cffunction>
</cfcomponent>

Then I'm doing:
<cfset variables.events = createObject("component", "events").readAll()
/>


<cfoutput>#variables.events#</cfoutput>

Thanks,
Ben
