cakephpで野球の打席結果のwebアプリケーション開発中です。入力内容を編集するページを作成したい

野球の打撃成績を登録して表示するwebアプリケーションを作成中です。最初に入力した内容に誤りなどがあった場合の内容を変更するページを作成したいのですが、controllerにどのような関数を使えばいいかわかりません。自分で作成した内容ですと、ブラウザでundefind.indexエラーが
$game->gameday=$p["year"]."年".$p["month"]."月".$p["day"]."日";
$game->result=((int)$p["result1"]-(int)$p["result2"])>0?"○":(((int)$p["result1"]-(int)$p["result2"])==0?"△":"●");
$game->score = $p["result1"]."-".$p["result2"];
$game->teamname = $p["team"];
$game->enemy = $p["enemy"];
$game->place = $p["place"];
$game->rbi = $p["rbi"];
$game->myscore = $p["myscore"];
$game->steal = $p["steal"];
$game->stealout = $p["stealout"];
で発生してしまいます。どうすればデータの編集ページにとび、内容の編集ができ、保存できるようになりますか。

cakephp

2        $p = $this->request->query("id");
3        $table = $this->getTableLocator()->get("games");
4        $table2 = $this->getTableLocator()->get("scores");
5        $pp = $this->request->getData();
6        $game = $table->find()->where("id=".$p)->first();
7        $p = $pp;
8        $game->gameday=$p["year"]."年".$p["month"]."月".$p["day"]."日";
9        $game->result=((int)$p["result1"]-(int)$p["result2"])>0?"○":(((int)$p["result1"]-(int)$p["result2"])==0?"△":"●");
10        $game->score = $p["result1"]."-".$p["result2"];
11        $game->teamname = $p["team"];
12        $game->enemy = $p["enemy"];
13        $game->place = $p["place"];
14        $game->rbi = $p["rbi"];
15        $game->myscore = $p["myscore"];
16        $game->steal = $p["steal"];
17        $game->stealout = $p["stealout"];
18        $table->save($game);
19        $this->set("list",$game);
20        $this->redirect(["controller"=>"top","action"=>"index","?"=>["id"=>$p]]);
21    }

createupdate/index.ctpこちらが編集ページになります。
