Query Posts with Multiple Taxonomies and Tax Terms

File: taxonomy-product_category.php

I’m trying to re-filter the main query based on a front-end filter/dropdown, where the user selects a location/term from the product_locations taxonomy.

From there I want all posts not in the selected location to be removed from the loop.

Loop below…

<?php //Setup query arguments to retrieve only posts that fall into both taxonomy categories / terms
$args = array(
	'post_type'      => get_post_type(),
	'orderby'        => 'menu_order',
	'order'          =>  'ASC',
	'posts_per_page' => -1,
	'no_found_rows'  => true,
	'tax_query' => array(
		'relation' => 'AND',
		array(
			'taxonomy' => 'product_category',
			'field'    => 'slug',
			'terms'    => array($category->slug), //Supply the current product_category terms
		),
		array(
			'taxonomy' => 'product_locations',
			'field'    => 'slug',
			'terms'    => array($current_location), //Add the product_locations term
			'operator' => 'IN',
		),
	),
);

//Should contain only the posts that fall under current post type and assigned to array of terms.
$query = new WP_Query( $args ); ?>

<?php //Now I want to loop through the tax terms from both "product_category" and "product_locations".

<?php if ( $query->have_posts() ) : ?>

	<?php $i = 0 ?>

	<?php while ( $query->have_posts() ) : $query->the_post(); $i++ ?>

		<!-- Loop through only posts that fall into both taxonomy term(s) / term groups -->

	<?php endwhile; ?>
		<div class="fix"></div>
	<?php else : ?>

		<p>Sorry, no products found.</p>

	<?php endif; ?>

<?php wp_reset_postdata() ?>

<?php wp_reset_query() ?>
