Question

如何通过带自定义字段的wp rest api v2正确创建自定义帖子类型记录？无法创建自定义字段或更新它们。

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为类别，位置，自定义帖子类型称为企业和自定义帖子类型的后置元素中的自定义字段

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

使用商家端点http://mysite/wp-json/wp/v2/businesses我可以通过api上传新商家，但创建的记录会忽略所有元键

例如给出以下内容

      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先前通过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字段以及listing_address

我可以查询通过其余api上传的记录，我得到这样的回复

$ 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重新查询并获得所有正确的字段返回但是POST请求更新（当然应该是PUT）记录仍然赢了＆＃39 ; t设置任何自定义字段

e.g。

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，而不是依赖于REST API Enabler插件只有一个字段来查看我是否可以使用它

<?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。

我现在完全陷入了尝试我能想到的一切。

Answer 1

我的wordpress插件有一个明显的问题，其中添加动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() {

做了这个改变，现在一切都好了
