Q&A
phpでSquareを用いた決済の実装を行っています。
まずはサンプルを試しています。ダウンロードしたサンプルはこちら。
https://github.com/square/connect-api-examples/tree/master/connect-examples/v2/php_payment
テストで本番決済できましたが、
Squareの管理画面のお取引に表示される商品が「任意の金額」となっております。
こちらにphpで吐き出した注文IDや商品名などを表示（登録）させたいのですが、
方法がわかりません…
ご存じの方いらっしゃいましたら、ご教示いただけますと幸いです。
以下、コードです。（gitのサンプルほぼそのままですが）
index.php（決済フォームのあるページ）
