我正在尝试获取类别name 而不是ID 来自我的自定义帖子类型的WP REST API。一些关于端点修改的文章给了我一些关于如何解决它的想法，但不幸的是，我没有让它发挥作用。这是我的代码（*删除了一些行中不相关的代码）：
CUSTOM POST TYPE
<?php
add_action( \'init\', \'portfolio_projects\' );
function portfolio_projects() {
$labels = array([...]);
$args = array(
[...]
\'show_in_rest\' => true,
\'rest_base\' => \'projects\',
\'rest_controller_class\' => \'Category_Data\',
\'supports\' => array( \'title\', \'thumbnail\', \'editor\'),
\'taxonomies\' => array(\'post_tag\', \'category\')
);
register_post_type( \'project\', $args );
}
CONTROLLER CLASS
<?php
/**
* Category data
*/
class Category_Data extends WP_REST_Posts_Controller
{
public function init()
{
add_action(\'rest_api_init\', array(
$this,
\'add_category_data\'
));
}
/**
* Add the category data
*/
public function add_category_data()
{
register_rest_field(\'project\', \'category_data\', [\'get_callback\' => array(
$this,
\'get_all_category_data\'
) , ]);
}
/**
* Get all the category data
*
* @param $object
* @param $field_name
* @param $request
*
* @return array
*/
public function get_all_category_data($object, $field_name, $request)
{
return get_the_category($object[\'id\']);
}
}
我很想听听你对此的想法和想法。谢谢

此代码将添加categories_names wp rest api响应字段：
function wpse_287931_register_categories_names_field() {
register_rest_field( \'project\',
\'categories_names\',
array(
\'get_callback\' => \'wpse_287931_get_categories_names\',
\'update_callback\' => null,
\'schema\' => null,
)
);
}
add_action( \'rest_api_init\', \'wpse_287931_register_categories_names_field\' );
function wpse_287931_get_categories_names( $object, $field_name, $request ) {
$formatted_categories = array();
$categories = get_the_category( $object[\'id\'] );
foreach ($categories as $category) {
$formatted_categories[] = $category->name;
}
return $formatted_categories;
}

同上，但将“project”替换为array(\'post\') 应该有用。
function wpse_287931_register_categories_names_field()
{
register_rest_field(
array(\'post\'),
\'categories_names\',
array(
\'get_callback\' => \'wpse_287931_get_categories_names\',
\'update_callback\' => null,
\'schema\' => null,
)
);
}
add_action(\'rest_api_init\', \'wpse_287931_register_categories_names_field\');
function wpse_287931_get_categories_names($object, $field_name, $request)
{
$formatted_categories = array();
$categories = get_the_category($object[\'id\']);
foreach ($categories as $category) {
$formatted_categories[] = $category->name;
}
return $formatted_categories;
}
