WordPress：使用post__not_in排除自定义分类类别

Question

我试图从循环中排除自定义分类法类别中的项目（slg： Private-Case-research，ID： 5）。我正在使用以下代码，有人有建议或想法为什么它不起作用吗？提前感谢！

    // 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
            ));
        }

Answer 1

post__not_in接受一个ID数组并排除它们。您希望使用category__not_in，它接受一个类别ID数组并排除它们。

请看一下文档。

Answer 2

//获取当前页面ID$this_post=$post-

    // 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
        ));
    }
