我有一个名为“portcat”的自定义帖子类型，我只想在我的页面上显示一个portcat类别（“games”-ID为“3”）的结果。下面的代码显示了所有类别，我不确定需要添加什么才能使其仅显示“游戏”类别？

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

    <?php echo $firstCat[0]->cat_name; ?>

    <div class="clear"></div>
    <ul class="blogpost_list columns3">

    <?php
    $temp = $wp_query;
    $wp_query = null;
    $wp_query = new WP_Query();
    $args = array(
    \'post_type\' => \'port\',
    \'paged\' => $paged,
    \'posts_per_page\' => get_theme_option("portfolio_work_count"),                 
    );


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

好的，我完全按照上面的建议做了（除了“category\\u name”不起作用，所以我用的是“cat\\u name”）。它仍在显示所有类别。。。我只想让它显示“游戏”。我已经包含了其余的代码，希望有人能很容易地发现我遗漏了什么？
