wordpress tip: control when your posts are displayed in your rss feed
The problem. Have you ever published an article and then immediately noticed an error? Sure, you can edit it, but there?s another problem: the article has already been published in your RSS feed. To avoid this kind of problem, use this recipe to create a delay between the publication of a post and its availability in your RSS feed.
The solution. To apply this hack, simply paste the following code into your theme?s function.php file. If your theme doesn?t have this file, just create it.
Code:
function publish_later_on_feed($where) {
global $wpdb;
if ( is_feed() ) {
// timestamp in WP-format
$now = gmdate('Y-m-d H:i:s');
// value for wait; + device
$wait = '5'; // integer
// http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_timestampdiff
$device = 'MINUTE'; //MINUTE, HOUR, DAY, WEEK, MONTH, YEAR
// add SQL-sytax to default $where
$where .= " AND TIMESTAMPDIFF($device, $wpdb->posts.post_date_gmt, '$now') > $wait ";
}
return $where;
}
add_filter('posts_where', 'publish_later_on_feed');
Code explanation.
The above code will add a 5-minute delay to the time between when your post is published on your blog and when it appears in your RSS feed. To change the length of the delay, change the value of the $wait variable on line 9. |
