FireFox download counter in ColdFusion
FireFox has a realtime download counter on their Spread Firefox site. They syndicate the counter as RSS, and there are lots of code snippets available to put it on your site. I found one that was in CF, but it didn't work. So I wrote my own and added it to this site in the top right. Here's the code:
<cfset feedUrl = "http://feeds.spreadfirefox.com/downloads/firefox">
<cfparam name="errorsFound" default="0">
<cftry>
<cfhttp url="#feedURL#" method="get" timeout="3" throwonerror="true"/>
<cfcatch type="any">
<cfset errorsFound = 1>
</cfcatch>
</cftry>
<cfif errorsFound eq 0>
<cfset dloadFeed = XMLParse(cfhttp.filecontent)>
<cfset numDownloads = dloadFeed.rss.channel.item.description.XmlText>
<div style="font-size:8pt; font-weight:bold; font-family: arial; text-align:center;">
<cfoutput>#NumberFormat(numDownloads,",")#</cfoutput>
downloads and
counting!</div>
<cfelse>
<div style="font-size:8pt; font-weight:bold; font-family: arial; text-align:center;">
<br /> <br /> <br /> <br />
</div>
</cfif>
<cfparam name="errorsFound" default="0">
<cftry>
<cfhttp url="#feedURL#" method="get" timeout="3" throwonerror="true"/>
<cfcatch type="any">
<cfset errorsFound = 1>
</cfcatch>
</cftry>
<cfif errorsFound eq 0>
<cfset dloadFeed = XMLParse(cfhttp.filecontent)>
<cfset numDownloads = dloadFeed.rss.channel.item.description.XmlText>
<div style="font-size:8pt; font-weight:bold; font-family: arial; text-align:center;">
<cfoutput>#NumberFormat(numDownloads,",")#</cfoutput>
downloads and
counting!</div>
<cfelse>
<div style="font-size:8pt; font-weight:bold; font-family: arial; text-align:center;">
<br /> <br /> <br /> <br />
</div>
</cfif>
I had a bug in it that I fixed today. Well, not really a bug. If the rss feed doesn't respond, the page will just spin until it hits the default timeout in the CF server. Today I added the code that sets a timeout, and if it doesn't get a response in 3 seconds, the code just displays a blank section. I put the blank section in so it looks good on my site, but you can modify it as best fits your site.
