我正在尝试在 Wordpress RestAPI 中注册自定义帖子类型。我已经完成了大部分工作（帖子本身和字段），但我仍然坚持让中继器字段注册。这是我到目前为止所拥有的。
这段代码位于我的主题文件夹中的 functions.php 文件中。我取出了一堆字段来缩短代码，因为它们都是字符串，并且就像给定字段“reservation-status”一样工作。
add_action( 'init', 'booking_register_meta' );
function booking_register_meta(){
//This bit registers my custom post type
register_post_type(
'reservations',
array(
'labels' => array(
'name' => _( 'Reservations' ),
'singular_name' => _( 'Reservation' ),
),
'public' => true,
'has_archive' => true,
'show_in_rest' => true,
'supports' => array(
'title',
'custom-fields',
'revisions',
)
)
);
//this bit registers my regular field
register_meta(
'post',
'reservation-status',
array(
'single' => true,
'type' => 'string',
'default' => '',
'show_in_rest' => true,
'object_subtype' => 'reservations'
)
);
//this bit is suppose to register my repeater field
register_post_meta(
'post',
'occupants',
array(
'single' => false,
'type' => 'array',
'show_in_rest' => array(
'schema' => array(
'items' => array(
'type' => 'string',
'properties' => array(
'occupant-first-name' => array(
'type' => 'string',
),
'occupant-last-name' => array(
'type' => 'string',
),
),
),
),
),
)
);
}
我正在使用这里的文档：Wordpress：修改响应
这是我使用 postman 时的 JSON 输出。（没有值的字段是正确的）。注意：元中缺少占用者。这是一个 GET 请求，该帖子的 resident Repeater 字段有信息输入。

如果您查看
register_post_meta()occupantspost从您的代码看来，您的自定义帖子类型是
reservationsoccupantsreservations类似：
register_post_meta(
'reservations',
'occupants',
array(
'single' => false,
'type' => 'array',
'show_in_rest' => array(
'schema' => array(
'items' => array(
'type' => 'string',
'properties' => array(
'occupant-first-name' => array(
'type' => 'string',
),
'occupant-last-name' => array(
'type' => 'string',
),
),
),
),
),
)
);
此外，以单数形式命名自定义帖子类型也是一个好习惯。
