当我使用下面的代码时,我的博客帖子页面上出现了“数组”这个词。我有一种感觉,它与这条线有关:

我正在为我的 PORTFOLIO 和 NEWS 页面使用类似的模板,其中这一行的措辞略有不同(“showportcat”和“shownewscat”而不是“get_the_category”),它应该显示类别,而是显示“数组”这个词在它的位置。

我试过“showpostcat”,但没用,所以我想知道是否需要重新措辞?或者问题可能出在我下面包含的代码的另一部分?

        <div class="greyblock">
            <h4 class="nomar"><?php echo the_title(); ?></h4>
            <div class="sep"></div>

                <?php echo get_the_category(get_the_ID()); ?>

                <div class="clear"></div>
                <ul class="blogpost_list columns2">

                <?php
                $temp = $wp_query;
                $wp_query = null;
                $wp_query = new WP_Query();
                $args = array(
                'post_type' => 'post',
                'paged' => $paged,
                'posts_per_page' => get_option("posts_per_page"),   
                );


                if (isset($_GET['slug'])) {
                $args['tax_query']=array( 
                        array( 
                            'taxonomy' => 'postcat',  
                            'field' => 'slug',  
                            'terms' => $_GET['slug']  
                         )
                    );
                }



                $wp_query->query($args);
                ?>
                <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); 
                #We have:
                #get_permalink() - Full url to post;
                #get_the_title() - Post title;
                #get_the_content() - Post text;
                #get_post_time('U', true) - unix timestamp

                $featured_image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );   


                echo "

                        foreach ( $terms as $term ) {
                            $draught_links[] = $term->name;
                        }

                        $on_draught = join( ", ", $draught_links );
                        }

怎么样:

$categories = get_the_category(get_the_ID());
foreach ($categories as $category) {
    echo $category;
}

问题仍然存在。我猜这与我对以下两行之一的措辞方式有关,因为它是用于投资组合的“showportcat”和用于新闻的“shownewscat”,但“showpostcat”不适用于帖子,所以我只是想不通出去:

 <?php echo get_the_category(get_the_ID()); ?>
 **OR**
 'taxonomy' => 'postcat',
