如何通过 WP REST API V2 正确创建带有自定义字段的自定义 Post 类型

Question

如何通过带有自定义字段的 wp rest api v2 正确创建自定义 post 类型的记录？无法创建或更新自定义字段。

我已经在自托管的 wordpress 安装中安装了 superlist 和 superlist-child 主题。

此主题使用自定义分类法作为类别、位置、自定义 Post 类型称为企业和自定义字段 post 元中的自定义 Post 类型

我正在尝试使用 rest api v2 将数据导入站点，并已成功创建自定义类别和位置。我使用 REST API Enabler 插件来注册自定义端点和自定义字段。

使用业务端点 http://mysite/wp-json/wp/v2/businesses 我可以通过 api 上传新业务，但创建的记录忽略所有元键

例如给定以下正文

      body = {
        title: company_name,
        listing_address: [address], 
        listing_map_location_latitude: [c.lat],
        listing_map_location_longitude: [c.lon],
        content: c.description,
        email: c.email,
        facebook: [c.facebook],
        image_url: c.image_url,
        locations: [c.city.server_id],
        listing_categories: c.categories.pluck(:server_id),
        listing_street_view: ["on"]
        status:"publish"
      }
      request = HTTParty.post(POSTS_END_POINT, body: body, headers: headers)

正确地将企业附加到正确的位置和自定义类别 (listing_categories) 之前通过 REST api 创建，但是 none 的自定义字段 (wp_postmeta table) 被填充，例如listing_locations lon 和 lat 字段和 listing_address

我可以通过rest查询上传的记录api得到这样的回复

$ rake upload:test
Result: {"id"=>1749, "date"=>"2016-02-20T05:06:01", "date_gmt"=>nil, "guid"=>{"rendered"=>"http://highstreetbeacons.com/?post_type=business&p=1749"}, "modified"=>"2016-02-20T05:06:01", "modified_gmt"=>nil, "slug"=>"", "type"=>"business", "link"=>"http://highstreetbeacons.com/?post_type=business&p=1749", "title"=>{"rendered"=>"Birmingham Museum and Art Gallery, Chamberlain Square, Birmingham, B3 3DH"}, "content"=>{"rendered"=>"<p>A description</p>\n"}, "author"=>1, "featured_media"=>0, "comment_status"=>"open", "ping_status"=>"closed", "listing_categories"=>[3779, 4095, 4061], "locations"=>[330], "_links"=>{"self"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/businesses/1749"}], "collection"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/businesses"}], "about"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/types/business"}], "author"=>[{"embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/users/1"}], "replies"=>[{"embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/comments?post=1749"}], "https://api.w.org/attachment"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/media?parent=1749"}], "https://api.w.org/term"=>[{"taxonomy"=>"listing_categories", "embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/listing_categories?post=1749"}, {"taxonomy"=>"locations", "embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/locations?post=1749"}]}}

这完全忽略了元键。如果在管理区域我手动点击生成的业务的更新按钮，我可以通过 api 重新查询并返回所有正确的字段，但 POST 请求更新（当然应该是PUT) 记录仍然不会设置任何自定义字段

例如

rake upload:test
Result: {"id"=>1745, "date"=>"2016-02-20T04:53:17", "date_gmt"=>nil, "guid"=>{"rendered"=>"http://highstreetbeacons.com/?post_type=business&#038;p=1745"}, "modified"=>"2016-02-20T04:53:17", "modified_gmt"=>"2016-02-20T04:53:17", "slug"=>"", "type"=>"business", "link"=>"http://highstreetbeacons.com/?post_type=business&p=1745", "title"=>{"rendered"=>"Birmingham Museum and Art Gallery, Chamberlain Square, Birmingham, B3 3DH"}, "content"=>{"rendered"=>"<p>A description</p>\n"}, "author"=>1, "featured_media"=>0, "comment_status"=>"open", "ping_status"=>"closed", "listing_categories"=>[3779, 4095, 4061], "locations"=>[330], "listing_featured_image"=>[""], "listing_banner"=>["banner_featured_image"], "listing_opening_hours"=>["a:7:{i:0;a:4:{s:11:\"listing_day\";s:6:\"MONDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:1;a:4:{s:11:\"listing_day\";s:7:\"TUESDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:2;a:4:{s:11:\"listing_day\";s:9:\"WEDNESDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:3;a:4:{s:11:\"listing_day\";s:8:\"THURSDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:4;a:4:{s:11:\"listing_day\";s:6:\"FRIDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:5;a:4:{s:11:\"listing_day\";s:8:\"SATURDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}i:6;a:4:{s:11:\"listing_day\";s:6:\"SUNDAY\";s:17:\"listing_time_from\";s:0:\"\";s:15:\"listing_time_to\";s:0:\"\";s:14:\"listing_custom\";s:0:\"\";}}"], "listing_map_location"=>["a:2:{s:8:\"latitude\";s:0:\"\";s:9:\"longitude\";s:0:\"\";}"], "listing_street_view_location_latitude"=>["37.812405"], "listing_street_view_location_longitude"=>["-122.47607800000003"], "listing_street_view_location_heading"=>["-18"], "listing_street_view_location"=>["a:5:{s:8:\"latitude\";s:9:\"37.812405\";s:9:\"longitude\";s:19:\"-122.47607800000003\";s:4:\"zoom\";s:1:\"1\";s:7:\"heading\";s:3:\"-18\";s:5:\"pitch\";s:2:\"25\";}"], "listing_locations"=>["a:1:{i:0;s:10:\"birmingham\";}"], "listing_listing_category"=>["a:3:{i:0;s:7:\"museums\";i:1;s:10:\"coffee-tea\";i:2;s:13:\"art-galleries\";}"], "_links"=>{"self"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/businesses/1745"}], "collection"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/businesses"}], "about"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/types/business"}], "author"=>[{"embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/users/1"}], "replies"=>[{"embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/comments?post=1745"}], "https://api.w.org/attachment"=>[{"href"=>"http://highstreetbeacons.com/wp-json/wp/v2/media?parent=1745"}], "https://api.w.org/term"=>[{"taxonomy"=>"listing_categories", "embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/listing_categories?post=1745"}, {"taxonomy"=>"locations", "embeddable"=>true, "href"=>"http://highstreetbeacons.com/wp-json/wp/v2/locations?post=1745"}]}}

我刚刚创建了一个插件来注册自定义字段，而不是依赖 REST API 启动器插件只有一个字段，看看我是否可以让它工作

<?php
/**
 * Plugin Name: Jamesc Register API Fields
 * Plugin URI: http://danielpataki.com
 * Description: This plugin exposes business meta data mfields to REST API.
 * Version: 1.0.0
 * Author: Smiler
 */


/**
 * Use arbitrary functions to add a field
 */
add_action( 'rest_api_init', 'register_something_random' );
function slug_register_something_random() {
    register_rest_field( 'business',
        'listing_address',
        array(
            'get_callback'    => 'get_meta_field',
            'update_callback' => 'update_meta_field',
            'schema'          => null,
        )
    );
}

/**
 * Handler for getting custom field data.
 *
 * @since 0.1.0
 *
 * @param array $object The object from the response
 * @param string $field_name Name of field
 * @param WP_REST_Request $request Current request
 *
 * @return mixed
 */
function get_meta_field( $object, $field_name, $request ) {
    return get_post_meta( $object[ 'id' ], $field_name );
}

/**
 * Handler for updating custom field data.
 *
 * @since 0.1.0
 *
 * @param mixed $value The value of the field
 * @param object $object The object from the response
 * @param string $field_name Name of field
 *
 * @return bool|int
 */
function update_meta_field( $value, $object, $field_name ) {
    if ( ! $value || ! is_string( $value ) ) {
        return;
    }

    return update_post_meta( $object->ID, $field_name, strip_tags( $value ) );

}

但这没有任何效果。

我现在完全无法尝试我能想到的一切。

Answer 1

我的 wordpress 插件有一个非常明显的问题，其中添加操作函数名称与实际函数名称不匹配 register_something_random 和 slug_register_something_random()

add_action( 'rest_api_init', 'register_something_random' );
function slug_register_something_random() {

应该是

add_action( 'rest_api_init', 'register_something_random' );
function register_something_random() {

进行了此更改，现在一切正常
