在开发WordPress企业主题时如何条用相关产品？

我们用wordpress开发企业主题的时候，如果有产品展示模块，那在浏览产品详情页的时候，我们经常会看到产品详情底部有一个相关产品显示。在开发WordPress企业主题时如何条用相关产品？其实对于这个模块我们并不陌生，因为在我们写文章详情页的时候，也写过调用当前文章的相关文章代码，在这里我贴一段在wordpress企业主题开发中经常使用的相关产品调用代码。

<?php
//get the taxonomy terms of custom post type
$customTaxonomyTerms = wp_get_object_terms( $post->ID, ‘product_category’, array(‘fields’ => ‘ids’) );
//query arguments
$args = array(
‘post_type’ => ‘products’,
‘post_status’ => ‘publish’,
‘posts_per_page’ => 4,
‘orderby’ => ‘rand’,
‘tax_query’ => array(
array(
‘taxonomy’ => ‘product_category’,
‘field’ => ‘id’,
‘terms’ => $customTaxonomyTerms
)
),
‘post__not_in’ => array ($post->ID),
);
//the query
$relatedPosts = new WP_Query( $args );
//loop through query
if($relatedPosts->have_posts()){
echo ‘<div class=”related-products”>’;
echo ‘<h3>’ . __(‘Related Products’) . ‘</h3>’;
echo ‘<ul>’;
while($relatedPosts->have_posts()){
$relatedPosts->the_post();
?>
<li>
<a href=”<?php the_permalink(); ?>”><?php the_post_thumbnail(‘product_thumb’); ?></a>
<a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a>
</li>
<?php
}
echo ‘</ul></div>’;
}else{
//no posts found
}
//restore original post data
wp_reset_postdata();
?>
