问题描述

如何通过带有自定义字段的 wp rest api v2 正确创建自定义帖子类型记录?无法创建或更新自定义字段.

How do I correctly create a custom post type record through the wp rest api v2 with custom fields? Unable to create custom fields or update them.

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

I have installed the superlist and superlist-child theme in a self hosted wordpress installation.

此主题使用自定义分类法用于类别、位置、称为业务的自定义帖子类型和自定义帖子类型的帖子元中的自定义字段

This theme uses Custom Taxonomies for categories, locations, Custom Post Types called businesses and custom fields in post meta for the Custom Post Type

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.

I am trying to import data to site using rest api v2 and have successfully created the custom categories and locations. I used the REST API Enabler plugin to register the custom endpoints and the custom fields.

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

Using the businesses endpoint http://mysite/wp-json/wp/v2/businesses I can upload a new business through the api but the record created ignores all the meta keys

例如给定以下主体

      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)

正确地将业务附加到之前通过 REST api 创建的正确位置和自定义类别(listing_categories)，但是没有填充任何自定义字段(wp_postmeta 表)，例如listing_locations lon 和 lat 字段和 listing_address

Correctly attaches the business to the correct location and custom categories (listing_categories) previously created through the REST api however none of the custom fields (wp_postmeta table) are populated e.g. listing_locations lon and lat fields and listing_address

我可以查询通过rest api上传的记录，得到这样的响应

I can query the record uploaded through the rest api and I get a response like this

$ 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.如果在管理区域中，我手动点击了生成业务的更新按钮，然后我可以通过 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

This totally ignores the meta keys. If in the admin area I manually hit the update button for the generated business I can then re-query through the api and get all the correct fields returned but an POST request to update (Surely should be a PUT) the record still won't set any of the custom fields

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，而不是依赖只有一个字段的 REST API Enabler 插件来查看我是否可以让它工作

I have just created a plugin to register the custom fields rather than relying on REST API Enabler plugin with just one field to see if I can get that to work

<?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 ) );

}

但这没有效果.

尝试了我能想到的所有方法后，我现在完全陷入困境.

I am now totally stuck having tried everything I can think of.

推荐答案

我的 wordpress 插件存在一个明显的问题，即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()

There was a glaringly obvious problem with my wordpress plugin where the add action function name did not match the actual function name register_something_random and slug_register_something_random() 

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

应该

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

进行了此更改，现在一切正常

Made this change and all is now ok
