php - tax_query 不适用于 WP_Query

Question

我一直在努力使以下代码工作，但它只是不起作用，我想知道可能是什么原因。

$args = array(
    'post_type' => 'project',
    'tax_query' => array(
                         array(
                               'taxonomy' => 'categories_project',
                               'field' => 'slug'
                         )
                   )
     );
$wp_query = new WP_Query( $args ); 

跑步<?php echo $GLOBALS['wp_query']->request; ?>让我明白：

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID 
FROM wp_posts 
INNER JOIN wp_term_relationships 
ON (wp_posts.ID = wp_term_relationships.object_id) 
WHERE 1=1 
AND ( wp_term_relationships.term_taxonomy_id IN (53) ) 
AND wp_posts.post_type = 'project' 
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') 
GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC 
LIMIT 0, 3

任何帮助都将受到高度评价。谢谢！

好的，我发现了问题，它需要一个术语！......

$args = array(
    'post_type' => 'project',
    'tax_query' => array(
                     array(
                           'taxonomy' => 'categories_project',
                           **'terms' => $term,**
                           'field' => 'slug'
                     )
               )
    );
$wp_query = new WP_Query( $args );
