How to Exclude Sticky Posts from the Loop in WordPress

How to take away the Sticky Ability of the Post

When you are displaying most recent posts in a tab, you do not want the sticky posts to stay sticky. If you do not remove the sticky features, the recent posts area would be useless as all of your sticky posts will crowd this area. This is when query_posts feature comes in handy.

To do this you will need to change your loop to something like this:

<?php
query_posts(‘caller_get_posts=1’);
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>

Completely exclude Sticky posts from the Loop

If you are using Sticky posts in a slider, then sometimes you might want to completely exclude your sticky posts from the loop. All what you have to do is edit your custom loop to match with this:

<?php
query_posts(array(“post__not_in” =>get_option(“sticky_posts”)));
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>

This code will not display any sticky posts in the post loop.
