Multiple WordPress Loops Explained

Basic loop

<?php if (have_posts()) : ?>

<?php while (have_posts()) : the_post(); ?>

<!-- do stuff ... -->

<?php endwhile; ?>

Using rewind_posts()

In order to loop through the same query a second time, call rewind_posts(). This will reset the loop counter and allow you to do another loop.

<?php rewind_posts(); ?>

<?php while (have_posts()) : the_post(); ?>

<!-- Do stuff... -->

<?php endwhile; ?>

List posts in a “featured” category with query_posts()

// Get the last 3 posts in the featured category.

<?php query_posts('category_name=featured&showposts=3'); ?>

<?php while (have_posts()) : the_post(); ?>

<!-- Do featured stuff... -->

<?php endwhile;?>

//We reset the loop

<?php rewind_posts(); ?>

//We build the normal loop that will list out blog posts

<?php while (have_posts()) : the_post(); ?>

<!-- Do stuff... -->

<?php endwhile; ?>

Create a new query object

<?php $my_query = new WP_Query('category_name=featured&showposts=3'); ?>

<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>

<!-- Do special_cat stuff... -->

<?php endwhile; ?>

Store your query for future use

Another version of using multiple Loops takes a different approach to getting around the inability to use have_posts() and the_post(). To solve this, you need to store the original query in a variable, then re-assign it when with the other Loop. This way, you can use all the standard functions that rely on all the globals.

// saving the query

<?php $temp_query = clone $wp_query; ?>

<!-- Do stuff... -->

//listing out featured articles

<?php query_posts('category_name=featured&showposts=3'); ?>

<?php while (have_posts()) : the_post(); ?>

<!-- Do special_cat stuff... -->

<?php endwhile; ?>

// restoring the query so it can be later used to display our posts

<?php $wp_query = clone $temp_query; ?>

How to: Show both excerpt and full post on homepage

Open up your index.php and look for the loop. Then replace the loop with the following code:

<?php if (have_posts()) :

while (have_posts()) : the_post();

$customField = get_post_custom_values(”full”);

if (isset($customField[0])) {

//Custom field is set, display a full post

the_title();

the_content();

} else {

// No custom field set, let’s display an excerpt

the_title();

the_excerpt();

endwhile;

endif;

?>
