我正试图在我的单曲上创建一个相关的帖子部分。php文件，我将此作为起点(http://www.wpbeginner.com/wp-tutorials/how-to-display-related-posts-in-wordpress/) 我的问题是，我不认为这个脚本是从自定义帖子类型调用的。只要主岗位区域有什么，没有岗位。他们都在CPT中。我该如何调整才能使其发挥作用？这里有一件事我已经试过了，但还是出现了错误。

<div class="relatedposts">  
            <h3>Related posts</h3>  
                <?php  
                    $orig_post = $post array( \'food\', \'film\', \'music\', \'art\', \'fashion\', \'photography\' );
                    global $post;  
                    $tags = wp_get_post_tags($post->ID);  

                    if ($tags) {  
                    $tag_ids = array();  
                    foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;  
                    $args=array(  
                    \'tag__in\' => $tag_ids,  
                    \'post__not_in\' => array($post->ID),  
                    \'posts_per_page\'=>4, // Number of related posts to display.  
                    \'caller_get_posts\'=>1  
                );  

                    $my_query = new wp_query( $args );  

                    while( $my_query->have_posts() ) {  
                    $my_query->the_post();  
                ?>  

                <div class="relatedthumb">
