Accumulo - RSS aggregation theme

[BinaryMoon]

Hope you don't mind me posting this here but we released a new Premium WordPress theme today. Since releasing http://WPTopics.com last year Darren had some requests to sell the theme so we tidied up the code and packaged it up as Accumulo

You can see the demo site here: http://demo.prothemedesign.com/wordpress/accumulo/

And the release post here: http://prothemedesign.com/news/accum...heme-released/

Would love any feedback and suggestions/ criticism you might have

Thanks. I didn't even know there was a built in fetch_feed function! Thanks for the tip

I built the BNS SMF Feeds plugin using the built-in fetch_feed() function, but the most recent updates required incorporating the code into the plugin so I could change the feed refresh frequency.

ryno267 - Yeah - we're using the built in fetch_feed functionality.

Edward - could you clarify what you mean about the refresh frequency, I think this may be related to a problem we've been having with feeds being cached for longer than intended. I've had a look but can't work out where the cache is stored or how it works. I do caching myself in the theme so any info you can give would be great.

Default feed caching time is 12 hours.

We discussed how you could change that over here:
Setting cache duration for SimplePie in WP?

Note, the URL bug I mention is fixed in 3.0. Not in 2.9 though.

ooh - thanks for the link. Interesting reading.

I have tried looking for the cache directory and can't find it anywhere (says it's ./cache). Can you tell me where the files are cached so I can clear them?

I borrowed heavily from the core files to create the BNS SMF Feeds plugin, specifically code from

../wp-includes/feed.php

and

../wp-includes/default-widgets.php

Inside feed.php you will find the fetch_feed() function ... I modified it like so:

 function bns_fetch_feed($url) {
    require_once (ABSPATH . WPINC . '/class-feed.php');

    $feed = new SimplePie();
    $feed->set_feed_url($url);
    $feed->set_cache_class('WP_Feed_Cache');
    $feed->set_file_class('WP_SimplePie_File');
    $feed->set_cache_duration(apply_filters('wp_feed_cache_transient_lifetime', $feed_refresh));
    $feed->init();
    $feed->handle_content_type();

    if ( $feed->error() )
        return new WP_Error('simplepie-error', $feed->error());

    return $feed;
} 
  

The user can then set the new $feed_refresh variable in the option panel (instead of the core default of 43200 seconds, or 12 hours); and, although it has not been tested 100%, I would expect the refresh frequency will work at different speeds within each instance of the widget.

The plugin was more about building a SMF Forum specific RSS URL than displaying the feed items ...

Just a quick update from me, I found the cache. It's stored in the database under wp_options as _transient_feed_XYZ (or something similar). Thanks for getting me started on this - helped a lot
