Answer 1

すべての拳、あなたのフォームは<form method="post">です。そのaction=ディレクティブはどこですか？何のURLをヒットするはずですか？そして、あなたはそれのためのURLハンドラを持っていますか？あなたのコードではMenuHandlerハンドラに行かなければならないと思います。

<form method="post" action="/menu_handler"> 

そして、あなたのURL処理が含まれている必要があります：

おそらくそれがあるべき

application = webapp.WSGIApplication([('/', MainPageHandler), 
        ('/menu_handler', MenuHandler), 
        ('/cart_handler', CartHandler), 
       ], 
       debug=True) 

次に、任意の投稿エラーがあるかどうかを確認するために、お使いのブラウザでコンソールを確認してください。あなたのMenuHandlerにログを追加して、投稿がそこに到着していることを確認してください。

これは良いスタートです。
