display related products by custom taxonomy

Hi. I assume you’re doing a template override on related.php. If not, you can read up on it here.
https://docs.woothemes.com/document/template-structure/

It looks like you’re using a custom taxonomy of ‘ranges’. I’ve edited related.php to check for terms in the ranges taxonomy and display related products based on those terms. If no terms are found, the default related products will be displayed.

<?php
/**
 * Related Products
 *
 * @author 		WooThemes
 * @package 	WooCommerce/Templates
 * @version     1.6.4
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly
}

global $product, $woocommerce_loop;

if ( empty( $product ) || ! $product->exists() ) {
	return;
}

//If ranges custom taxonomy, show related ranges
if ($ranges = get_the_terms($product->id, 'ranges')) {

	//Ranges IDs array
	$ranges_ids = array();

	foreach($ranges as $range) {
		$ranges_ids[] = $range->term_id;
	}

	//Create the args
	$args = array(
		'post_type'				=> 'product',
		'ignore_sticky_posts'	=> 1,
		'posts_per_page'		=> $posts_per_page,
		'no_found_rows' 		=> 1,
		'orderby' 				=> $orderby,
		'post__not_in'			=> array($product->id),
		'tax_query'				=> array(array(
										'taxonomy'	=> 'ranges',
										'field'		=> 'id',
										'terms'		=> $ranges_ids,
									)),
	);
} else {

	$related = $product->get_related( $posts_per_page );

	if ( sizeof( $related ) == 0 ) return;

	$args = apply_filters( 'woocommerce_related_products_args', array(
		'post_type'            => 'product',
		'ignore_sticky_posts'  => 1,
		'no_found_rows'        => 1,
		'posts_per_page'       => $posts_per_page,
		'orderby'              => $orderby,
		'post__in'             => $related,
		'post__not_in'         => array( $product->id )
	) );

}

$products = new WP_Query( $args );

$woocommerce_loop['columns'] = $columns;

if ( $products->have_posts() ) : ?>

	<div class="related products">

		<h2><?php _e( 'Related Products', 'woocommerce' ); ?></h2>

		<?php woocommerce_product_loop_start(); ?>

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

				<?php wc_get_template_part( 'content', 'product' ); ?>

			<?php endwhile; // end of the loop. ?>

		<?php woocommerce_product_loop_end(); ?>

	</div>

<?php endif;

wp_reset_postdata();

Let me know if this works for you.

Hi,
I would like to display all products of a vendor in a page. I am using the below code but it displays all products of all vendors. But I want only products of a paricular vendor.

function is_vendor_page()
{
$vendortax = get_query_var( ‘taxonomy’ );
if( $vendortax== shop_vendor)
{
$vendor_id = get_queried_object()->term_id;
$wp_query = new WP_Query( array(
‘post_status’ => ‘publish’,
‘posts_per_page’ => 99,
‘post_type’ => ‘product’,
‘tax_query’ => array(
‘taxonomy’=> ‘shop_vendor’, ‘field’ => ‘id’, ‘terms’ => $vendor_id)
) );
if ($wp_query->have_posts() ) {
while ( $wp_query->have_posts() ) {
$wp_query->the_post();
………
……….
}
}

can you please help me in this?

Exactly what I needed! Thank you so much, @mike Moore!!
