Question

我有这些数据：

id      meta_key   meta_value
1       d_t_w      4 weeks
2       d_t_w      2 Days
3       d_t_w      3 Weeks
4       d_t_w      4 Days
5       d_t_w      1 Week

WP查询：

$query['orderby'] = 'd_t_w'; 
$query['order'] = ASC;  
$query = new WP_Query($query);

结果：

  id      meta_key   meta_value
  5       d_t_w      1 Week 
  2       d_t_w      2 Days   
  3       d_t_w      3 Weeks  
  4       d_t_w      4 Days
  1       d_t_w      4 weeks

但我的期望是：

id      meta_key   meta_value
2       d_t_w      2 Days
4       d_t_w      4 Days
5       d_t_w      1 Week
3       d_t_w      3 Weeks
1       d_t_w      4 weeks

如何按照自定义价值（1天，2天，3天，......，3周，4周）申请订单

Answer 1

如果您的表meta_value后缀与周数相同，那么您可以使用此方法

SELECT meta_value,
REPLACE(
REPLACE(
REPLACE(REPLACE(meta_value,' weeks','00'),' week','00'),' Days','0'),' Day','0'
    ) as odr 
 FROM `product` 
 ORDER by CAST(odr AS UNSIGNED)

Answer 2

在原始查询语言（wordpress indipendent）中，您可以提取字段并计算字符串的天数以订购查询

像这样

SELECT
    *
FROM (
    SELECT '1 Week' as c
    UNION ALL SELECT '2 Days'
    UNION ALL SELECT '3 Days'
    UNION ALL SELECT '3 Weeks'
    UNION ALL SELECT '1 Day'
    ) as t
ORDER BY TRIM(SUBSTR(t.c, 1, LOCATE(' ', t.c))) *
    IF(TRIM(SUBSTR(LOWER(t.c), LOCATE(' ', t.c))) = 'week', 7,
        IF(TRIM(SUBSTR(LOWER(t.c),LOCATE(' ', t.c))) = 'weeks', 7,
            IF(TRIM(SUBSTR(LOWER(t.c), LOCATE(' ', t.c))) = 'day', 1,
                IF(TRIM(SUBSTR(LOWER(t.c), LOCATE(' ', t.c))) = 'days', 1,
                    1)))) ASC;

Answer 3

您的查询应该是这样的：

$args = array(
'orderby'   => 'meta_value',
'meta_key'  => 'meta_value',
'order'     => 'ASC',
);
$query = new WP_Query( $args );

Answer 4

您可以使用正常的日期/时间order_by ASC / DESC进行查询，然后将元值转换为d_t_w。

Answer 5

我通过添加过滤器解决了这个问题：

add_filter( 'posts_orderby', 'deliver_to_weeks', 11, 2 );
    function deliver_to_weeks( $orderBy, $query ) {  

        $orderBy = str_ireplace('wp_postmeta.meta_value', "field(wp_postmeta.meta_value, '1 Day', '2 Days', '3 Days', '4 Days', '5 Days' , '1 Week', '2 Weeks', '3 Weeks', '4 Weeks')", $orderBy);
        return $orderBy;
    }
