我正在使用amchart wordpress插件，并希望通过wp rest API为其添加支持。
以下是我迄今为止所做的：
在/包括/设置。php（添加到$args数组：这将创建/wp/v2/charts路由）
\'show_in_rest\' => true,
\'rest_base\' => \'charts\'
自定义帖子类型已在安装程序中注册。php组件：
register_post_type( \'amchart\', $args );
插件中有4个字段，它们都存储在wp\\U Posteta表中
试图注册rest字段时，我已将其添加到的底部/包括/设置。php文件：
add_action("rest_api_init", function () {
register_rest_field("amchart", "_amcharts_html",
[ "get_callback" => function ($post, $field_name, $request, $object_type) {
return get_user_meta($post["id"], $field_name, TRUE);
},"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
update_user_meta($post->ID, $field_name, $value);
},]);
});
add_action("rest_api_init", function () {
register_rest_field("amchart", "_amcharts_javascript",
[ "get_callback" => function ($post, $field_name, $request, $object_type) {
return get_user_meta($post["id"], $field_name, TRUE);
},"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
update_user_meta($post->ID, $field_name, $value);
},]);
});
add_action("rest_api_init", function () {
register_rest_field("amchart", "_amcharts_resources",
[ "get_callback" => function ($post, $field_name, $request, $object_type) {
return get_user_meta($post["id"], $field_name, TRUE);
},"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
update_user_meta($post->ID, $field_name, $value);
},]);
});
add_action("rest_api_init", function () {
register_rest_field("amchart", "_amcharts_slug",
[ "get_callback" => function ($post, $field_name, $request, $object_type) {
return get_user_meta($post["id"], $field_name, TRUE);
},"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
update_user_meta($post->ID, $field_name, $value);
},]);
});
我尝试通过..将这两个有效负载传递给api/wp/v2/图表
{
\'post_type\':\'amchart\',
\'_amcharts_resources\':\'resource list goes here\',
\'_amcharts_html\':\'html content\',
\'_amcharts_javascript\':\'javascript content\',
\'_amcharts_slug\':\'slug\',
\'title\': \'title\',
\'status\': \'publish\'
}
{
\'post_type\': \'amchart\',
\'title\': \'title\',
\'status\': \'publish\',
\'meta\': {
\'_amcharts_resources\':\'resource list goes here\',
\'_amcharts_html\':\'html content\',
\'_amcharts_javascript\':\'javascript content\',
\'_amcharts_slug\':\'slug_testing\'
}
}
在任何一种情况下，都会创建amchart类型的post，但不会向数据库中添加相关数据。显然，Title在post\\u type=\'post\'中是标准的，但所有元数据都没有进入wp\\u postesta表。
知道我做错了什么吗？

我在这里找到了一个解决方案。
将此添加到安装程序中的$args。php
\'show_in_rest\' => true,
\'rest_base\' => \'charts\'
将其添加到设置的底部。php文件
首先，您要在rest界面中注册要获取/设置的字段。然后将特定元数据注册到post\\u type=amchart
add_action("rest_api_init", function () {
register_rest_field("amchart", "_amcharts_html",
[
"get_callback" => function ($post, $field_name, $request, $object_type) {
return get_post_meta($post["id"], $field_name, true);
},
"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
return update_post_meta($post->ID, $field_name, $value);
}
]);
register_rest_field("amchart", "_amcharts_javascript",
[
"get_callback" => function ($post, $field_name, $request, $object_type) {
return get_post_meta($post["id"], $field_name, TRUE);
},
"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
return update_post_meta($post->ID, $field_name, $value);
}
]);
register_rest_field("amchart", "_amcharts_resources",
[
"get_callback" => function ($post, $field_name, $request, $object_type) {
return get_post_meta($post["id"], $field_name, TRUE);
},
"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
return update_post_meta($post->ID, $field_name, $value);
}
]);
register_rest_field("amchart", "_amcharts_slug",
[ "get_callback" => function ($post, $field_name, $request, $object_type) {
return get_post_meta($post["id"], $field_name, TRUE);
},
"update_callback" => function ($value, $post, $field_name, $request, $object_type) {
return update_post_meta($post->ID, $field_name, $value);
}
]);
});
register_meta(\'amchart\', \'_amcharts_html\', array(
"type" => "string",
"show_in_rest" => true,
"object_subtype" => "amchart"
));
register_meta(\'amchart\', \'_amcharts_javascript\', array(
"type" => "string",
"show_in_rest" => true,
"object_subtype" => "amchart"
));
register_meta(\'amchart\', \'_amcharts_resources\', array(
"type" => "string",
"show_in_rest" => true,
"object_subtype" => "amchart"
));
register_meta(\'amchart\', \'_amcharts_slug\', array(
"type" => "string",
"show_in_rest" => true,
"object_subtype" => "amchart"
));
有效的帖子正文为：
{
\'post_type\':\'amchart\',
\'_amcharts_resources\':\'resource list goes here\',
\'_amcharts_html\':\'html content\',
\'_amcharts_javascript\':\'javascript content\',
\'slug\':\'_amcharts_slug\', //or just use the response.id value as the slug if you do not set this explicitly
\'title\': \'title\',
\'status\': \'publish\' //draft, publish, etc
}
