【EC-CUBE4】PAY.JPの決済プラグインを作る方法

EC-CUBE4でPAY.JPの決済プラグインを作る方法です。

PAY.JPはクレジットカード情報のトークン化が簡単にできますのでとても便利です。

クレジットカード情報のトークン化は以下のようなテンプレートを用意するだけです。

{#
    Shopping/index.twigに追記
    {{ include('@PayJP/credit.twig', ignore_missing=true) }}
#}
{% if Order.Payment.getMethodClass == 'Plugin\\PayJP\\Service\\Method\\CreditCard' %}
    <div class="ec-orderPayment">
        <div class="ec-rectHeading">
            <h2>クレジットカード</h2>
            <div class="ec-input">
                <script
                        type="text/javascript"
                        src="https://checkout.pay.jp/"
                        class="payjp-button"
                        data-key="{{ payjp_public_key }}"
                        data-submit-text="トークンを作成する"
                        data-partial="true"
                        data-token-name="{{ form.payjp_token.vars.full_name }}">
                </script>
            </div>
        </div>
    </div>
{% else %}
    {{ form_widget(form.payjp_token, {type: 'hidden'}) }}
{% endif %}

Shopping/index.twigに追記

{% if Order.Payment.getMethodClass == 'Plugin\\PayJP\\Service\\Method\\CreditCard' %}

<h2>クレジットカード</h2>

<script

type="text/javascript"

src="https://checkout.pay.jp/"

class="payjp-button"

data-key="{{ payjp_public_key }}"

data-submit-text="トークンを作成する"

data-partial="true"

data-token-name="{{ form.payjp_token.vars.full_name }}">

</script>

</div>

{% else %}

{{ form_widget(form.payjp_token, {type: 'hidden'}) }}

{% endif %}

EC-CUBE4にはPaymentMethodInterfaceが用意されているのでシンプルな決済処理でしたら以下のように簡単に実装できます。
