# Query multiple custom post types in single loop

I'm aware there are several other posts that cover similar ground to what I'm about to ask.

I have three custom post types running, in addition to 'posts'. I want to run a loop that pulls all posts categorised under a particular category

 <?php
$args = array( 'post_type' => 'testimonial', 'posts_per_page' => 1, 'tax_query' => array( array ( 'taxonomy' => 'testimonial_category', 'field' => 'slug', 'terms' => 'home' ) ) );$query = new WP_Query( $args );$postcount = 0;
?>
<?php if ($query->have_posts()) : ?> <?php while ($query->have_posts()) : $query->the_post(); ?> <?php$postcount++; ?>
//loop here
<?php wp_reset_query(); ?>


This is the code I have at the moment, not sure how I condense this into pulling in multiply post types from one category.

Just change the post_type bit to:

'post_type' => array('testimonial', 'other_post_type', 'another-post-type'),

Assuming that taxonomy is valid across all 3 post types. Otherwise you'll have to leave that out.

Why? You can pass an array to post_type field.

How do I say what category name to search in. 'taxonomy' => 'testimonial_category' –  dannyw24 Jun 18 '13 at 13:49
@user2478101 : ^^ Your tax_query in the question looks OK, though I didn't test it. What are you trying to do differently? –  s_ha_dum Jun 18 '13 at 13:57
I have a taxonomy in each post type with a term in called home.I want to pull in any post that has that selected –  dannyw24 Jun 18 '13 at 14:00
I took a gamble and tried this, but it doesn't seem to pull in the other any posts from the custom post types. query_posts( array( 'post_type' => array('post', 'testimonial', 'casestudy'), 'cat' => 69, 'showposts' => 3 ) ); –  dannyw24 Jun 18 '13 at 14:16
In order for this to work, the taxonomy must be identical for all. The terms, as far as I know, can't be linked across taxonomies. core.trac.wordpress.org/ticket/12269 –  GhostToast Jun 18 '13 at 14:17
