wp_reset_query()
Destroys the previous query and sets up a new query.
Description
This should be used after query_posts() and before another query_posts(). This will remove obscure bugs that occur when the previous WP_Query object is not destroyed properly before another is set up.

More Information
query_posts() will change your main query and is not recommended. Only use if absolutely necessary. Creating a new instance of WP_Query or get_posts() is preferred for secondary loops. If you would like to modify the main query, use the pre_get_posts action.
Using after a Custom Loop
The following example shows how to use wp_reset_query() after a custom loop. Note that the loop in the example is probably being used in addition to the main loop.
<?php $args = array ( 'post_parent' => 5 ); query_posts( $args ); if ( have_posts() ): while ( have_posts() ) : the_post(); // Do stuff with the post content. the_title(); the_permalink(); // Etc. endwhile; else: // Insert any content or load a template for no posts found. endif; wp_reset_query(); ?>Expand full source codeCollapse full source code
