我有一个定制的post类型产品（葡萄酒）。以下各项都是自定义分类法：

在葡萄酒的单一产品视图中，我想进行以下查询：

1） 查找所有具有same family, same size 但是来自different vintage

2） 查找same family 并拥有same vintage 还有一个different size.

现在的问题是numeric year 是的自定义术语元属性vintage term. 这个numeric bottle size 是大小术语的自定义术语元属性。

对于第一个查询，我尝试了以下操作：

                $other_years = get_posts(array(
                  \'post_type\' => \'product\',
                  \'numberposts\' => -1,
                  \'tax_query\' => array(
                    array(
                      \'taxonomy\' => \'family\',
                      \'field\' => \'id\',
                      \'terms\' => $family->term_id, // Where term_id of Term 1 is "1".
                      \'include_children\' => false
                    ),
                    array(
                      \'taxonomy\' => \'size\',
                      \'field\' => \'id\',
                      \'terms\' => $size->term_id, // Where term_id of Term 1 is "1".
                      \'include_children\' => false
                    ),
                    array(
                      \'taxonomy\' => \'vintage\',
                      \'field\' => \'id\',
                      \'terms\' => array($vintage->term_id), // Where term_id of Term 1 is "1".
                      \'include_children\' => false,
                      \'operator\' => \'NOT IN\'
                    ),
                  )
                ));

It works. 然而：与其比较term_id （此处：年份的术语id）我想比较术语自定义元值（year\\u numeric）是否不同。

有没有可能进行这样的查询？

$other_years_terms = get_terms(
     \'taxonomy\'     =>  \'vintage\',
     \'meta_key\'     =>  \'year_numeric\',
     \'meta_value\'   =>  $the_current_wine_year,   // You\'ll have to figure that out
     \'meta_compare\' =>  \'!=\',
     \'fields\'       =>  \'ids\'
);

$other_years_posts = get_posts(array(
              \'post_type\' => \'product\',
              \'numberposts\' => -1,
              \'tax_query\' => array(
                array(
                  \'taxonomy\' => \'family\',
                  \'field\' => \'id\',
                  \'terms\' => $family->term_id, // Where term_id of Term 1 is "1".
                  \'include_children\' => false
                ),
                array(
                  \'taxonomy\' => \'size\',
                  \'field\' => \'id\',
                  \'terms\' => $size->term_id, // Where term_id of Term 1 is "1".
                  \'include_children\' => false
                ),
                array(
                  \'taxonomy\' => \'vintage\',
                  \'field\' => \'term_id\',
                  \'terms\' => $other_years_terms,
                ),
              )
            ));
