WP_Query使用'OR'获取两个不同分类的帖子

Question

我想获得两种不同分类法的帖子。

我想列出职位只有那些帖子要么有标签longform 或 post_format是键入link 。

我尝试过下面的代码，但它不起作用：

$query = new WP_Query(array(
   'relation' => 'OR',
    'posts_per_page' => 2,
    array(
        'taxonomy' => 'post_format',
        'field' => 'slug',
        'terms' => array( 'link' ) // Single terms as string - multiple as array
    ),
    array(
        'taxonomy' => 'Tag',
        'field' => 'id',
       'tag__in' => array('16') // 16 is the code for tag longform
    )
));

Answer 1

$terms = array('link');
$tax = array(16)

 $args = array( 
                           'post_type' => 'post',
                           'tax_query' => array(
                            'relation' => 'OR',
                                    array(
                                        'taxonomy' => 'post_format',
                                        'field'    => 'slug',
                                        'terms'    => $terms,
                                    ),
                                    array(
                                        'taxonomy' => 'space',
                                        'field'    => 'id',
                                        'tag__in'    => $tax,
                                    ),
                            ),
                           'posts_per_page' => 2
                        );


                    $the_query = new WP_Query( $args );

这应该工作！
