WordPress：使用post__not_in排除自定義分類類別

Question

我正在嘗試從循環中排除自定義分類法類別（項：private-case-study，ID：5）中的項目。 我正在使用以下代碼，是否有人對它不能正常工作提出建議或想法？ 提前致謝！

// Get the current page ID
        $this_post = $post->ID;
        $private_case_study = get_term_by('slug', 'private-case-study', 'mgt_portfolio_filter');


        // Show items from specific category
        if($category_name == '') {
            $wp_query = new WP_Query(array(
                'post_type' => 'mgt_portfolio',
                'posts_per_page' => $posts_per_page,
                'orderby'    => $orderby,
                'order' => $order,
                'post__not_in' => array($this_post, $private_case_study)
            ));
        } else {
            $wp_query = new WP_Query(array(
                'post_type' => 'mgt_portfolio',
                'tax_query' => array(
                    array(
                        'taxonomy' => 'mgt_portfolio_filter',
                        'field'    => 'slug',
                        'terms'    => $category_name,
                    ),
                ),
                'posts_per_page' => $posts_per_page,
                'orderby'    => $orderby,
                'post__not_in' => array($this_post, $private_case_study),
                'order' => $order
            ));
        }

//獲取當前頁面ID $ this_post = $ post-> ID; $ private_case_study = get_term_by（'slug'，'private-case-study'，'mgt_portfolio_filter'）;

    // Show items from specific category
    if($category_name == '') {
        $wp_query = new WP_Query(array(
            'post_type' => 'mgt_portfolio',
            'posts_per_page' => $posts_per_page,
            'orderby'    => $orderby,
            'order' => $order,
            'post__not_in' => array($this_post)
        ));
    } else {
        $wp_query = new WP_Query(array(
            'post_type' => 'mgt_portfolio',
            'tax_query' => array(
                array(
                    'taxonomy' => 'mgt_portfolio_filter',
                    'field'    => 'slug',
                    'terms'    => $category_name,
                ),
            ),
            'posts_per_page' => $posts_per_page,
            'orderby'    => $orderby,
            'post__not_in' => array($this_post),
            'order' => $order
        ));
    }

post__not_in采用ID數組並排除它們。 您要使用category__not_in ，它接受一個類別ID數組並將其排除在外。

看一下文檔 。
