Add Your Data

Create an event handler feed.cfc with the code below and save it to the handlers directory. In the code you will notice there are four functions which should be self explanatory. The rss function reads the feed XML file and displays it on screen as RSS+XML content. While the generate function sets the feed's Metadata. This Metadata is set to the rc.feed structure. The feed items are set to rc.feed.items with the content fetched from the model feeditems.generateItems(). The ColdBox plug-in feedGenerator() is then called to convert the CFML structure/query data into a RSS formatted XML file. This file is saved to includes\xml\my_first_feed.xml.
