我有一个带有自定义类别分类法的自定义帖子类型。在CPT single templae上，我想列出相同类别的其他帖子，但我无法让它发挥作用。
我的当前代码：
<?php
foreach ( Roots\\Sage\\Utils\\get_the_category_bytax( get_the_ID(), \'project_category\' ) as $cat )
$category_ids[] = $cat->term_id;
$projects = new WP_Query( array(
\'post_status\' => \'publish\',
\'post__in\' => get_post_meta( get_the_ID(), \'carbonlimits_project_related\', true ),
\'post__not_in\' => array( $current_post_id ),
\'category__and\' => $category_ids,
\'post_type\' => \'project\',
\'caller_get_posts\' => 1,
\'posts_per_page\' => 4
) );
while ( $projects->have_posts() ): $projects->the_post() ?>
<div id="project-<?php the_ID() ?>" <?php post_class( \'col-sm-3\' ) ?>>
<a href="<?php the_permalink() ?>">
<?php
$thumbnail = get_the_post_thumbnail( get_the_ID(), \'project-listing\' );
if ( $thumbnail )
echo $thumbnail;
else
echo \'<img src="/wp-content/themes/carbonlimits/dist/images/blank.gif" width="380" height="380">\';
?>
<h3><?= $projects->post->post_title ?></h3>
<span class="view-btn">View</span>
</a>
</div>
<?php endwhile;
// var_dump( $projects->request );
wp_reset_postdata();
?>
是因为它是一种自定义的帖子类型和分类法吗？

这应该适用于自定义分类法。
<?php
function get_related_posts() {
global $post;
$taxonomy = \'your_custom_taxonomy\';
$terms = wp_get_post_terms( $post->ID, $taxonomy );
if($terms) {
$term_arr = \'\';
foreach( $terms as $term ) {
$term_arr .= $term->slug . \',\'; // create array of term slugs
}
$args = array(
\'showposts\' => 5, // you can change this to whatever you need
\'post__not_in\' => array($post->ID) // exlude current post from results
\'tax_query\' => array(
array(
\'taxonomy\' => $taxonomy,
\'field\' => \'slug\', // using \'slug\' but can be either \'term_id\', \'slug\' or \'name\'
\'terms\' => $term_arr // array of ID values, slugs or names depending what \'field\' is set to
)
)
);
$related_posts = get_posts( $args );
if($related_posts) {
foreach ( $related_posts as $post ) : setup_postdata( $post );
// output whatever you want here
the_title(); // for example
endforeach;
} else {
echo \'No Related Posts\';
}
}
wp_reset_postdata();
}
?>
