# 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 );
   
       }
       ```
