Though I'm not an avid follower of RSS feeds, I use Twitter as a primary method of receiving news, updates from friends, and application-related notifications, so my friend's immediate suggestion - to use Twitterfeed as a way to keep up on Craigslist jobs - seemed like a great idea.
Unfortunately, Twitterfeed adds two Google Analytics variables to website URLs, which, while not an issue with dynamic pages, presents problems with Craigslist's static HTML pages.
The bolded section above shows the problem; adding variables to a static page breaks the page, and if you click the link above you'll see that the page cannot be found.
There's a Craigslist-specific fix for this below; it's not great, but it gets the job done.
$rss=preg_replace("/<link>(.*?)<\/link>/", "<link>$new_link$1", $rss);
else if ($link=$_GET['link'])
Just upload the above code to your server as craigslistrss.php and change $website to the correct URL and path. You can now integrate RSS feeds from Craigslist with Twitter without breaking the page; just link to your script instead of directly to the RSS feed in the following format:
That's it! Hopefully Twitterfeed will integrate an option to disable Analytics variables soon, but in the meantime that will get the job done.
