WordPress 获取不在自定义分类术语中的帖子

Question

以下代码应该获取自定义分类中没有特定术语的帖子。目前它仍然吸引着他们。是不是少了点什么。

$args = array(
            'numberposts' => '3',
            'post__not_in' => $post_not_in,
            'tax_query' => array(
                'taxonomy' => 'topic',
                'terms' => 9,      
                'field' => 'id',
                'operator' => 'NOT IN'
            ) 
        ); 
        $extras = get_posts($args);

Answer 1

Important Note: tax_query takes an array of tax query arguments arrays (it takes an array of arrays)

你尝试过吗？

$args = array(
    'numberposts' => '3',
    'post__not_in' => $post_not_in,
    'tax_query' => array(
        array(
            'taxonomy' => 'topic',
            'terms' => 9,      
            'field' => 'id',
            'operator' => 'NOT IN'
        )
    )
); 
$extras = get_posts($args);
