【中文标题】Wordpress：tax_query 使用 OR 运算符的多个术语

【英文标题】：Wordpress: tax_query multiple terms using OR operator

【发布时间】：2018-03-13 22:00:34

【问题描述】：

简单查询，但由于某种原因未显示正确的帖子，尝试显示带有 monthly-to-do-list 术语的帖子，如果没有结果，则显示与社区的帖子 -事件的术语。有什么建议吗？

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
        'relation' => 'OR',
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => 'monthly-to-do-list',
                ),
            array(
                'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => 'community-events',
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);

【参考方案1】：

尝试添加数组并使其如下所示：

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
        'relation' => 'OR',
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('monthly-to-do-list'),
                ),
            array(
                'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('community-events'),
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);

您可能会注意到 terms 是复数，因此您也可以像这样简化查询：

$todo_args = array(
   'cat' => $my_category_id,
   'posts_per_page' => 1,
   'tax_query' => array(
            array(
               'taxonomy' => 'postkicker',
                'field'    => 'slug',
                'terms'    => array('monthly-to-do-list','community-events'),
                ),
            ),
    'orderby' => 'date',
    'order' => 'DESC'
);
