好的，我正在使用一个模板（我已经联系了开发人员，他们没有帮助，所以我正在根据需要修改模板页面）。该模板使用以下代码显示公文包项目：

            <div class="container filter-portfolio clearfix">
        <ul id="portfolio" class="clearfix">
                <?php 
                        $type = \'portfolio\';
                        $args=array( \'post_type\' => $type, \'posts_per_page\' => -1 );
                        query_posts( $args );   

                        if (have_posts()) : while (have_posts()) : the_post();                  
                        $terms = get_the_terms( $post->ID, \'portfolio_categories\' ); ?>

                        if (has_post_thumbnail()) {                 
                            $thumb = get_post_thumbnail_id();
                            $thumb_w = \'460\';
                            $thumb_h = \'272\';
                            $image_src = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), \'full\');
                            $image_url = $image_src [0];
                            $attachment_url = wp_get_attachment_url($thumb, \'full\');
                            $image = aq_resize($attachment_url, $thumb_w, $thumb_h, true);                          
                        }           


                        $thumbnail = wp_get_attachment_image_src(get_post_thumbnail_id(), \'grid-thumb\');

                            foreach ( $terms as $term ) {
                                    $cats[0] = $term->name;
                                    $catname = join($cats);     
                                    $catname = preg_replace(\'/\\s/\', \'\', $catname);                                  
                            }
                        $title= get_the_title();
                        $title= explode(\' \',$title);
                        $title[0]= \'<span class="bold">\'.$title[0].\'</span>\';
                        $title= implode(\' \',$title);
                    ?>  

            <!-- PORTFOLIO ITEM -->
                <li data-id="id-<?php echo $post->ID; ?>" data-type="<?php 
                            $terms = get_the_term_list( $post->ID, \'portfolio_categories\',\'\',\' , \',\'\' ); 
                            $terms = preg_replace(\'/\\s/\',\'\', $terms);
                            $terms = strip_tags( $terms );
                            $terms = preg_replace(\'/[\\s,\\-!]/\',\' \', $terms);
                            echo $terms;
                            ?>" class="four columns m-bot-25">
                            <div class="content-container-white">
                                <div class="view view-first">
                                    <img src="<?php echo $image; ?>" alt="<?php the_title(); ?>" />
                                    <div class="mask">
                                        <h2><?php echo $title; ?></h2>
                                        <a href="<?php echo $attachment_url; ?>" class="lightbox zoom info"></a>
                                        <a href="<?php the_permalink(); ?>" class="link info"></a>
                                    </div>  
                                </div>
                                <div class="lw-item-caption-container">
                                    <a class="a-invert" href="<?php the_permalink(); ?>" ><?php echo $title; ?></a>
                                </div>
                            </div>
                </li>

      <?php endwhile; ?>    
        </ul>

    </div>

基本上，我只需要显示与某个slug匹配的帖子，它可以从$条件下检索。但是，当我尝试以下代码修改时：

if( $terms->slug != \'product-gallery\' ) continue;

放置在$terms=get\\u the\\u terms（…）之后行，似乎循环被打破了，页面上根本没有显示帖子。重要的是，我可以过滤帖子，并按slug进行过滤，因为我不能太多地修改主题，客户端需要能够按有slug的类别添加/删除帖子。

免责声明：我不熟悉WP环境、php和mysql。然而，我学得很快，在C++、Java、Perl等方面有丰富的编码经验。我对web开发还很陌生。

对于我的目标，我错过了什么或做错了什么？

谢谢

if( $terms->slug != \'product-gallery\' )

if ( in_array( \'product-gallery\', $terms ) ) continue;
