我正在使用高级自定义字段插件，我有一个名为“course”的自定义帖子类型，其中一些来自ACF的字段与之相关。
我有以下代码：
function update_course($course_id) {
//Check conditions and tell user if certain values are incorrect/inconsitence
$nr_available = intval(get_field(\'nr_available\'));
$nr_registered = intval(get_field(\'nr_registered\'));
echo \'nr avail=\' . $nr_available;
echo \'nr registered=\' . $nr_registered;
}
add_action( \'edit_post\' , \'update_course\');
我想做的事情是检查可用点是否少于，然后注册=不正确。然后我想指出用户做得不正确。
但无论如何，我真正的问题是，我不知道如何（我不知道）从发布的自定义帖子类型的ACF中获取值（当然）。
上面只会返回数据库中的实际值（我认为对于当前课程），I want the posted values. 如果我查看$\\u POST变量，它会显示如下内容：
[field_524bceba787b8] => 800 [field_524bcf0a787b9] => 40 [field_524bcf58787ba] => 50 [field_524bcfdb787bb] => [field_524bd005787bc] => [field_5253d4b31053b] => 0
UPDATE:整个阵列看起来像：
