单词“Array"出现在博客帖子页面


Word "Array" is Appearing on Blog Posts Page

当我使用下面的代码时,我得到了"数组"这个词出现在我的博客POSTS页面上。我有一种感觉,它与这一行有关:

我正在使用一个类似的模板,我的投资组合和新闻页面,其中的措辞在这一行略有不同("showportcat"answers"shownewcat"而不是"get_the_category"),它应该显示类别,但相反,这个词"数组"是在它的地方。

我试过"showpostcat",但没有工作,所以我想知道我是否需要重新措辞?或者问题是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 "
                <li class='pc'>
                        <img alt='".get_the_title()."' src='".TIMTHUMBURL."?w=400&h=400&src=".$featured_image[0]."'>
                        <h4>".get_the_title()."</h4>";
                        $terms = get_the_terms($post->ID, 'postcat');
                        if ( $terms && ! is_wp_error( $terms ) ) {
                        $draught_links = array();
                        foreach ( $terms as $term ) {
                            $draught_links[] = $term->name;
                        }
                        $on_draught = join( ", ", $draught_links );
                        }
                echo "
                <p>".get_the_excerpt()."</p>
                    <a href='".get_permalink()."' class='read'>Read more</a>                        
                    <br class='clear' />
                </li>
                ";  
                 endwhile; ?>
            </ul>
        </div>
        <?php get_pagination() ?>
        <?php $wp_query = null; $wp_query = $temp;  ?>   

如何:

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

问题仍然存在。我猜这与我在下面两行中的表述方式有关,因为"showportcat"表示作品集,"shownewcat"表示新闻,但"showpostcat"不适用于帖子,所以我就是想不明白:

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