E&T Filter: Display Scheduled (Future-Dated) Feed Items

There are times when you might need to use an RSS feed that has posts scheduled in the future, such as an events feed. 

For this reason, we’ve put together these two filters, both of which show options for  only future items, and both future and past items. In the second example, the feed source IDs used (100, 200) need to be changed to the IDs of your own feed sources.

Apply the Filter to All Feed Sources

add_filter( 'wprss_display_feed_items_query', 'my_show_future_events', 10, 2 );
function my_show_future_events( $args, $settings ) {
    $args['order'] = 'ASC';
 
    // to show future-dated items only, uncomment the line below
    // $args['post_status'] = array('future');
 
    // to show both future-dated and past items, uncomment the line below
    // $args['post_status'] = array('publish', 'future');

    return $args;
}

Apply the Filter to Selected Feed Sources Only

add_filter( 'wprss_display_feed_items_query', 'my_show_future_stories', 10, 2 );
function my_show_future_stories( $args, $settings ) {
 
        // replace 100 and 200 with your own feed source IDs.
        // you can add as many as you like, or even just one.
	$allowed_sources = array('100', '200'); 
 
	$order = 'ASC';
 
	// to show future-dated items only
	$status = array('future');
 
	// to show both future-dated and past items
	// or add other status codes as needed
	// $status = array('publish', 'future');
 
	if (!isset($args['meta_query'])) {
        $args['order'] = $order;
        $args['post_status'] = $status;
		return $args;
	}
 
	if (!is_array($args['meta_query'])) {
		return $args;
	}
 
	$meta_query = $args['meta_query'];
	foreach ($meta_query as $_idx => $_meta) {
		if ($_meta['key'] !== 'wprss_feed_id'
				|| !isset($_meta['value'])) {
			continue;
		}
 
		$value = is_array($_meta['value'])
			? $_meta['value']
			: array($_meta['value']);
		
		$matched_values = array_intersect($value, $allowed_sources);
		if (!count($matched_values)) {
			continue;
		}
		
        $args['order'] = $order;
        $args['post_status'] = $status;
		
		break;
	}
 
    return $args;
}
