php – 从WordPress API中取消数据(wp-json)

我可以从wordpress API返回的json中取消设置(从正常帖子中删除细节).我实际上使用下面的例子： https://css-tricks.com/using-the-wp-api-to-fetch-posts/

我遇到麻烦和无法弄清楚的是如何更改这一点,从而从“自定义帖子类型”中取消数据

思考？

function qod_remove_extra_data( $data,$post,$context ) {
  // We only want to modify the 'view' context,for reading posts
  if ( $context !== 'view' || is_wp_error( $data ) ) {
    return $data;
  }

  // Here,we unset any data we don't want to see on the front end:
  unset( $data['author'] );
  unset( $data['status'] );
  unset( $data['featured_image'] );
  //etc etc

  return $data;
}

add_filter( 'json_prepare_post','qod_remove_extra_data',12,3 );

自定义帖子类型示例过滤器：

function projectPost_remove_extra_data( $data,$context ) {

  if ( $context !== 'view' || is_wp_error( $data ) ) {
    return $data;
  }

  // Here,we unset any data we don't want to see on the front end:
  unset( $data['author'] );



  return $data;
}

add_filter( 'json_prepare_project','projectPost_remove_extra_data',3 );

对于wp-api v1.x,您需要扩展WP_JSON_CustomPostType.页面文件中有一个例子(class-wp-json-pages.PHP)

<?PHP
/**
 * Page post type handlers
 *
 * @package wordpress
 * @subpackage JSON API
 */

/**
 * Page post type handlers
 *
 * This class serves as a small addition on top of the basic post handlers to
 * add small functionality on top of the existing API.
 *
 * In addition,this class serves as a sample implementation of building on top
 * of the existing APIs for custom post types.
 *
 * @package wordpress
 * @subpackage JSON API
 */
class WP_JSON_Pages extends WP_JSON_CustomPostType {
    /**
     * Base route
     *
     * @var string
     */
    protected $base = '/pages';

    /**
     * Post type
     *
     * @var string
     */
    protected $type = 'page';

    /**
     * Register the page-related routes
     *
     * @param array $routes Existing routes
     * @return array Modified routes
     */
    public function register_routes( $routes ) {
        $routes = parent::register_routes( $routes );
        $routes = parent::register_revision_routes( $routes );
        $routes = parent::register_comment_routes( $routes );

        // Add post-by-path routes
        $routes[ $this->base . '/(?P<path>.+)'] = array(
            array( array( $this,'get_post_by_path' ),WP_JSON_Server::READABLE ),array( array( $this,'edit_post_by_path' ),WP_JSON_Server::EDITABLE | WP_JSON_Server::ACCEPT_JSON ),'delete_post_by_path' ),WP_JSON_Server::DELETABLE ),);

        return $routes;
    }

    /**
     * Retrieve a page by path name
     *
     * @param string $path
     * @param string $context
     *
     * @return array|WP_Error
     */
    public function get_post_by_path( $path,$context = 'view' ) {
        $post = get_page_by_path( $path,ARRAY_A );

        if ( empty( $post ) ) {
            return new WP_Error( 'json_post_invalid_id',__( 'Invalid post ID.' ),array( 'status' => 404 ) );
        }

        return $this->get_post( $post['ID'],$context );
    }

    /**
     * Edit a page by path name
     *
     * @param $path
     * @param $data
     * @param array $_headers
     *
     * @return true|WP_Error
     */
    public function edit_post_by_path( $path,$data,$_headers = array() ) {
        $post = get_page_by_path( $path,array( 'status' => 404 ) );
        }

        return $this->edit_post( $post['ID'],$_headers );
    }

    /**

     *
     * @param $path

     * @return true|WP_Error
     */
    public function delete_post_by_path( $path,$force = false ) {
        $post = get_page_by_path( $path,array( 'status' => 404 ) );
        }

        return $this->delete_post( $post['ID'],$force );
    }

    /**
     * Prepare post data
     *
     * @param array $post The unprepared post data
     * @param string $context The context for the prepared post. (view|view-revision|edit|embed|single-parent)
     * @return array The prepared post data
     */
    protected function prepare_post( $post,$context = 'view' ) {
        $_post = parent::prepare_post( $post,$context );

        // Override entity Meta keys with the correct links
        $_post['Meta']['links']['self'] = json_url( $this->base . '/' . get_page_uri( $post['ID'] ) );

        if ( ! empty( $post['post_parent'] ) ) {
            $_post['Meta']['links']['up'] = json_url( $this->base . '/' . get_page_uri( (int) $post['post_parent'] ) );
        }

        return apply_filters( 'json_prepare_page',$_post,$context );
    }
}

将“页面”替换为“MyCustomPostTypes”,页面替换为“mycustomposttype”.只要小心不要重命名也使用术语页面的内部wordpress 代码

注意：最好将其添加为插件,而不是更改JSON-WP-API插件

/**
 * Plugin Name: MyCustom JSON App API
 * Description: MyCustomPost handler for the JSON API
 * Dependency:  This plugin requires JSON-WP-API Plugin!!!! 
 * Author: 
 * Author URI: 
 * Version: 
 * Plugin URI:
