WordPress产品主题内容中的链接代码

WordPress主题站在创建产品主题后，可以设置一个转接至产品购买的链接代码，方便用户点击购物，今天就把代码给大家标注出来：   

以下就是相关代码：

<?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();

?>
