wordpress - 使用 WP_Query 获取所有没有条款的帖子

Question

我正在写一个 wordpress 循环，我想获得所有没有分配术语的帖子。有没有简单的方法来做到这一点？或者我真的必须获得所有术语 ID 并进行这样的税务查询:

// Get all the term id's
$terms = array();
$terms = getAllTheTerms();

// Create an arguments which get all the posts that do not have a term with any
// of the id's.
$args = array(
    'post_type' => 'post',
    'tax_query' =>
        array(
            'taxonomy' => 'actor',
            'field' => 'id',
            'terms' => $terms,
            'operator' => 'NOT IN'
    )
);
$query = new WP_Query( $args );

这似乎是一个愚蠢的查询，因为在数据库方面，无需查询即可轻松获取所有帖子。

Answer 1

$terms = get_terms( $taxonomy, array('fields'=>'ids')); /* GET ALL TERMS FROM A TOXNOMY */
$args = array(
    'tax_query' => array(
        array(
            'taxonomy' => $taxonomy,
            'field'    => 'term_id',
            'terms'    => $terms,
            'operator' => 'NOT IN' /* DO THE MAGIC -  Get all post that no in the taxonomy terms */
        )
    )
);
$the_query = new WP_Query( $args );
