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();
			?>
