wp_handle_uploadエラー "指定されたファイルはアップロードテストに失敗しました"が、それでも添付ファイルを作成しますか？

Question

画像アップロードのカスタムメタボックスに少し問題があります。アップロードされた画像は添付ファイルとして作成されますが、wp_handle_uploadは投稿メタを更新するのではなく、「指定されたファイルのアップロードテストに失敗しました」というエラーを取り消すようです。添付ファイルは問題なく作成されているのに奇妙に思える？

コードは次のとおりです。

// Make the forms multipart
add_action('post_edit_form_tag', 'post_edit_form_tag');
function post_edit_form_tag() {
   echo ' enctype="multipart/form-data"';
}

/* Setup custom meta boxes for posts */
$new_meta_boxes =
    array(
    "xxxx_kw1" => array(
        "name" => "xxxx_kw1",
        "std" => "",
        "title" => "Keyword 1",
        "type" => "text"
        ),
    "xxxx_url1" => array(

代わりに media_handle_upload() を使ってみてください。私にも同じような問題を解決しました。
