我将为您翻译以下内容:
我可以从WordPress内置函数get_post_meta中检索这些值。
而结果是:
我在我的 WooCommerce 网站中使用 Woothemes 预订。
由于我正在为产品构建自定义搜索,因此我还必须搜索可用性,以下是我应该如何从 B.O(后台管理)管理可用性 以及插件如何存储到数据库中。

我可以从WordPress内置函数get_post_meta中检索这些值。
$avail = get_post_meta($product->id, '_wc_booking_availability');
而结果是:
Array
(
[0] => Array
(
[type] => days
[bookable] => yes
[from] => 3
[to] => 3
)
[1] => Array
(
[type] => custom
[bookable] => yes
[from] => 2015-07-09
[to] => 2015-07-09
)
[2] => Array
(
[type] => custom
[bookable] => yes
[from] => 2015-07-08
[to] => 2015-07-08
)
[3] => Array
(
[type] => custom
[bookable] => yes
[from] => 2015-07-10
[to] => 2015-07-10
)
[4] => Array
(
[type] => custom
[bookable] => yes
[from] => 2015-07-15
[to] => 2015-07-15
)
[5] => Array
(
[type] => custom
[bookable] => yes
[from] => 2015-07-16
[to] => 2015-07-16
)
[6] => Array

[type] => custom
[bookable] => yes
[from] => 2015-07-17

)

[type] => months

[from] => 8
[to] => 8
)
)
如您所见,用户能够指定产品在一定的日期或月份内是否可预订,那么我的问题是如何进行SQL查询以检查该产品的某个日期变量是否可用。我认为meta_query可以完成这项工作(如下),但我该如何指定不可用日期?您怎么看?
if($_GET['when']){
/* checkIsAValidDate() >> check date format */
if ( checkIsAValidDate( $_GET['when'] ) ){
$quand = $_GET['when'];
$available = array(
"post_type" => "product",
"meta_query" => array(
"relation" => "AND",
"key" => '_wc_booking_availability',
"value" => $when,
'compare' => 'IN'
)
);
}
}
