Fetch_Feed cache time

  • Please update Fetch_Feed to support an optional parameter for the cache time value.

    I know that I can change the global time using the wp_feed_cache_transient_lifetime filter, but I need the ability to set individual cache times. Some feeds I want to update more quickly than others.

    In my testing, I modified fetch_feed with the following:

    function fetch_feed( $url, $cache_time = NULL )
 ...
	if ($cache_time == NULL) {
	  $cache_time = apply_filters( 'wp_feed_cache_transient_lifetime', 12 * HOUR_IN_SECONDS, $url );
	}
...
	$feed->set_cache_duration( $cache_time );

    which doesn’t break existing calls, but allows me to set individual cache times for feeds.

  • You can always remove the filter directly after the call to fetch_feed(). Probably better than hacking core is to create a wrapper function that allows you set the cache time individually for each feed.

    function dn_fetch_feed( $url, $cache_time = false ) {
     if ( $cache_time ) {
         add_filter( 'wp_feed_cache_transient_lifetime', function() {
             return $cache_time;
         });
         $feed = fetch_feed( $url );
         remove_all_filters( 'wp_feed_cache_transient_lifetime' );

        return $feed;
    }

    return fetch_feed( $url );

}
