Question

我需要在wordpress自定义帖子类型的单个页面中添加相关的帖子功能。我的帖子属于多个类别，并且在显示其内容时，帖子在顶部显示两次，并且其本身也显示在相关内容中发布部分。我尝试使用此代码

<?php
        $backup = $post;  // backup the current object
        $found_none = '<h2>No related posts found!</h2>';
        $taxonomy = 'news-category';//  e.g. post_tag, category, custom taxonomy
        $param_type = 'news-category'; //  e.g. tag__in, category__in, but genre__in will NOT work
        $post_types = get_post_types( array('public' => true), 'names' );
        $tax_args=array('orderby' => 'none');
        $tags = wp_get_post_terms( $post->ID , $taxonomy, $tax_args);
        if ($tags) {
          foreach ($tags as $tag) {
            $args=array(
              "$param_type" => $tag->slug,
              'post__not_in' => array($post->ID),
              'post_type' => $post_types,
              'showposts'=>-1,
              'caller_get_posts'=>1
            );
            $my_query = null;
            $my_query = new WP_Query($args);
            if( $my_query->have_posts() ) {
              while ($my_query->have_posts()) : $my_query->the_post(); ?>
                <div class="related_post_item">
                <h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h2>
                <div class="news_date"><?php echo get_the_date('F Y', $post->ID); ?></div>
                <?php $found_none = ''; ?>
                                </div>
            <?php  endwhile;
            }
          }
        }
        if ($found_none) {
        echo $found_none;
        }
        $post = $backup;  // copy it back
        wp_reset_query(); // to use the original query again
        ?>

每个帖子检查一个类别时，它的效果非常好，但我的帖子属于多个类别。如果检查了多个类别，如何正确检测相关帖子？

嘿，我找到了一个简单的解决方案。跟踪当前帖子的ID，当显示我的循环时添加了以下代码

            $exclude = $GLOBALS['current_id'];
            $args=array(
              "$param_type" => $tag->slug,
               'post__not_in' => array($exclude),
              'post_type' => $post_types,
              'showposts'=>-1,
              'caller_get_posts'=>1
            );

就是这样!!
