Wordpress：使用 post__not_in 排除自定义分类类别

Question

我正在尝试从循环中排除自定义分类类别（slug：private-case-study，ID：5）中的项目。我正在使用以下代码，有没有人有建议或想法为什么它不起作用？提前致谢！

// 获取当前页面ID $this_post = $post->ID; $private_case_study = get_term_by('slug', '私人案例研究', 'mgt_portfolio_filter'); // 显示特定类别的项目 if($category_name == '') { $wp_query = 新的 WP_Query(数组( 'post_type' => 'mgt_portfolio', 'posts_per_page' => $posts_per_page, 'orderby' => $orderby, '订单' => $订单， 'post__not_in' => 数组（$this_post, $private_case_study） )); } 别的 { $wp_query = 新的 WP_Query(数组( 'post_type' => 'mgt_portfolio', 'tax_query' => 数组（ 大批（ '分类' => 'mgt_portfolio_filter', '字段' => '蛞蝓'， '条款' => $category_name, ), ), 'posts_per_page' => $posts_per_page, 'orderby' => $orderby, 'post__not_in' => 数组（$this_post, $private_case_study）， '订单' => $订单 )); }

Answer 1

//获取当前页面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 接受一个 ID 数组并排除它们。您想使用category__not_in，它采用一组类别 ID 并将它们排除在外。

看看documentation。
