Re: RSS feed with JS is displaying old dates

[Jeremy Geerdes]

Well, I haven't completely gone through your code, but here are a couple of thoughts for you.

First, you might want to produce a page which reproduces this issue with only the bare minimum code. There seems to be a lot of extraneous stuff.

Second, once you've produced that page, post a link to it rather than the code itself. This allows us to utilize debugging tools and makes helping you immensely easier.

Third, RSS in general struggles with future dates. You might want to consider something different.

Finally, you say that the feed is only accessible internally. If that's the case, then the Feeds API will be totally useless to you. It has to be able to access the feed, or it won't be able to cache it.

If you could at least work on the first two of these things, I would be happy to take a look and see if I can help.

The RSS feed has no dates on it at all. However once this code runs, it will still display old dates/events anyways. I have been working on this for awhile with no avail.

The actual RSS feed isn't view able to those outside the network but here is the JS.

I want ONLY future dates. As of now a display_all gives me dates back from January and then only 1 future date.

here is the code: 

(function($){

    var feed_url    = o.feed_url;
    var link_url    = o.link_url
    var display_all = o.display_all; //Set to 'true' to display all calendar entries without filters

    /*----------------- end Configuration  ------------------------*/

    /*----------------- No need to edit below this line  ------------------------*/

    $('div#calendar').prepend('<div id="loading"></div>');

If you're in the Des Moines, IA, area, check out Debra Heights Wesleyan Church!

[Thomas Palumbo]

The site can be found here: http://cge.fsu.edu you can see the "no events currently scheduled" at the bottom of the page. (Even though there are events in the future.)

The link to the feed is not viewable from the outside but here is the end of the link: &cpath=&rssview=daysfrom&days=31&getdate  (so you can see it is displaying correctly, future dates)

And I can attach the javascript file if you need that.
