在我的wp网站上,我有2个类别和一些类似的帖子..
cat_1- post 1, post 2, post 3.
cat_2- post 2, post 3, post 4.
当我在帖子3页面时,我想仅显示来自类别2的相关文章。这是我的代码:但它返回空。可能我没有抓住逻辑。任何帮助将受到高度赞赏。
<?php
$terms = get_the_terms( $post_id, 'category' );
if( empty( $terms ) ) $terms = array();
$term_list = wp_list_pluck( $terms, 'slug' );
$related_args = array(
'post_type' => 'post',
'posts_per_page' => -1,
'post_status' => 'publish',
'post__not_in' => array( get_the_ID() ),
'orderby' => 'desc',
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => $term_list
),
array(
'taxonomy' => 'category',
'terms' => array('cat_1'),
'field' => 'slug',
'operator' => 'NOT IN',
),
),
);
$related = new WP_Query( $related_args );
if( $related->have_posts() ):
?>
<div class="post-navigation">
<h3>Related posts</h3>
<ul>
<?php while( $related->have_posts() ): $related->the_post(); ?>
<li><?php the_title(); ?></li>
<?php endwhile; ?>
</ul>
</div>
<?php
endif;
wp_reset_postdata();
?>

以下是以下查询...可能对您有所帮助......
$custom_tex=array(array('taxonomy'=>'category','field'=>'slug','terms'=>'cat_2'));
$new = new WP_Query(array('post_type'=>'post','posts_per_page'=>-1, 'tax_query'=>$custom_tex,'order' => 'DESC','orderby' => 'ID' ));
while ($new->have_posts()) : $new->the_post();
echo $post->post_title;
echo "<br>";
endwhile;
