WordPressにPHPからｶﾃｺﾞﾘを作成現在､XML-RPC経由でWordPressを使っております｡記事の投稿はできるのですが｢新しくｶﾃｺﾞﾘを作成｣する方法がわかりません｡右…

ｶﾃｺﾞﾘの新規登録のｴｯｾﾝｽを書きだすと､こんな感じになると思います｡

<?php
 require_once("XML/RPC.php");

 $GLOBALS['XML_RPC_defencoding'] = "UTF-8";
 
 $host = "ｻｲﾄのURL";
 $xmlrpc_path = "/xmlrpc.php";

 $blog_id = ﾌﾞﾛｸﾞID;
 $user = ﾕｰｻﾞｰ名;
 $pass = ﾊﾟｽﾜｰﾄﾞ; 

 $category_name = ｶﾃｺﾞﾘ名;
 $category_slug = ｶﾃｺﾞﾘｽﾗｯｸﾞ;
 $category_parent_id = 親のID;
 $category_description = ｶﾃｺﾞﾘの説明;
 

 $client = new XML_RPC_client($xmlrpc_path, $host, 80);
 
 $blog_id = new XML_RPC_Value($blog_id, 'int');
 $user = new XML_RPC_Value($user, 'string');
 $pass = new XML_RPC_Value($pass, 'string');

 $category = new XML_RPC_Value(
 array(
 'name' => new XML_RPC_Value($category_name, 'string'),
 'slug' => new XML_RPC_Value($category_slug, 'string'),
 'parent_id' => new XML_RPC_Value($category_parent_id, 'int'),
 'description' => new XML_RPC_Value($category_description, 'string')
 ),
 'struct');

 $request = new XML_RPC_Message(
 'wp.newCategory',
 array($blog_id, $user, $pass, $category)
 );

 $response = $client->send($request);
?>

ﾒｿｯﾄﾞ名と､ﾊﾟﾗﾒｰﾀの型や意味は､↓で調べます｡

後､Services_Blogging じゃありませんが､XML_RPC を使うﾗｲﾌﾞﾗﾘを書いている人がいました｡

でも､blogger ﾒﾝﾊﾞｰが構築されて無いような気がするので､このままでは使えないような気がします｡

既に回答されていますが､MetaWeblog APIではｶﾃｺﾞﾘｰの作成が出来ませんので､新規ｶﾃｺﾞﾘｰの作成だけWordPress APIを使用してはいかがでしょうか？

各APIの対応状況は上記ﾍﾟｰｼﾞの通りですが､新ﾊﾞｰｼﾞｮﾝの3.2.xの場合は､｢wp-includes/class-wp-xmlrpc-server.php｣で確認できます｡

･ｶﾃｺﾞﾘ作成のｺｰﾄﾞ

http://codex.wordpress.org/XML-RPC_wp#wp.newCategory

require_once("IXR_Library.php");

$rpc = new IXR_Client("http://blog.example.com/xmlrpc.php");

$status = $rpc->query(
 "wp.newCategory",
 "1",
 "UserName", // username
 "Password", // password
 array(
 "name"=>"ｶﾃｺﾞﾘ1",
 "slug"=>"category1",
 "parent_id"=>"", // 親ｶﾃｺﾞﾘのID
 "description"=>"ｶﾃｺﾞﾘ1について" //ｶﾃｺﾞﾘの説明
 )
);

$data = $rpc->getResponse( );
//print_r( $data ); 出力確認

//上記の処理以降に､MetaWeblog APIによる投稿のｺｰﾄﾞを記述します｡

｢IXR_Library.php｣は次のﾍﾟｰｼﾞでﾀﾞｳﾝﾛｰﾄﾞできます｡
