WordPress代码实现相关推荐功能

WordPress一些企业主题有一个功能非常不错，就是相关推荐。可以增加更多潜在成交几率以及用户粘性，对SEO优化也是极具帮助。

但并不是每个主题都有这种功能，我们不想放弃当前主题，网站又想具有这个功能怎么办？

只要将代码复制到文章底部，并对应添加我们的css样式就可以了，可以自由设置推荐文章数量和列表形式。代码如下：

<?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();

?>
