Best way to Rotate Posts

How do you rotate posts? So when you are on the main page that has all your posts, it is always changing, (rotating every 5 minutes).

 

Without a plugin we would have to manually modify the homepage query.

This could be added to your theme's functions.php file:

<?php


/**
 * Randomize front page post
 * 
 * @author Bill Erickson (modded by Hudson Atwell (@atwellpub)
 * @link http://www.billerickson.net/customize-the-wordpress-query/
 * @param object $query data
 *
 */
add_action( 'pre_get_posts', 'frontpage_randomize_post' );
function frontpage_randomize_post( $query ) {

	if( $query->is_main_query() && $query->is_home() ) {
		$query->set( 'order', 'RAND' );
                $query->set( 'limit', '1' );
	}

}

Code (markup):

This may not work if caching is enabled.

 

Search the Wordpress site plug-ins section for "rotating posts."

Quite a few show up, for example this one:
