我是wordpress新手，目前正在使用wordpress Rest API帮助使用现有数据自动创建自定义帖子。需要的字段之一是图像ID数组，以便可以显示图像。如果在wordpress上手动创建带有图像的帖子，我知道元数据需要采用这种格式
"fave_property_images":["18339","18337","18321","17794","17793","17792","17791","17790","17789","17787"]
但是，通过WordPress Rest API发布后，元数据会自动序列化，并且不会显示任何图像。
"fave_property_images":["a:3:{i:0;s:5:\\"18297\\";i:1;s:5:\\"18337\\";i:2;s:5:\\"17855\\";}"]
有没有办法防止我的数据自动序列化？
Edited 更改了我的getcallback函数，引用自https://developer.wordpress.org/reference/functions/register_rest_field/
功能。php
function add_fave_property_images() {
register_rest_field(\'property\',
\'fave_property_images\',
array(
\'get_callback\' => \'get_post_meta_for_api\',
\'update_callback\' => \'rest_update_property_meta\',
\'schema\' => array(
\'type\' => \'array\',
\'items\' => array(
\'type\' => \'string\',
),
),
)
);
}
function get_post_meta_for_api( $object ) {
//return the post meta
return get_post_meta( $object[\'id\'], \'fave_property_images\', false) ;
}
function rest_update_property_meta($value, $post, $field_name) {
// Update the field
return update_post_meta($post->ID, $field_name, $value);
}
我也试过了
maybe_unserialize() 无济于事。如果有任何帮助，我将不胜感激。谢谢！
2nd Edit我目前正在使用postman来发布，只是为了测试。这是我正在发送的json示例

3rd edit 我已成功在上显示阵列

property_meta 仍然是一个序列化数组，这是来自/wp-json/wp/v2/schools的结果示例json

然而，如果我通过在wordpress上编辑帖子来添加图像，json将如下所示
fave_property_images 在下面
property_meta 将只是一个数组。
