There are two solutions. 1) Programmatically: You can make any configuration field, store specific. And from that you can check, in code if you need to activate your module or not. With the file /app/code//yourcompany/yourmodule/etc/system.xml, thanks to the tags show_in_default, show_in_store, show_in_website, you can set a configuration field store view, website or by default.

因此,你必须建立一个“积极”的组合领域。 这意味着,付款方法配置领域的“活动”途径是付款/付款名称/活动。

而且,从这条道路上看,如果你把支付班级延长。 Mage_Payment_Model_Method_ 摘要是,Magento将检查能否获得付款模块。

2. 检查等级和方法 Mage_Payment_Model_Method_Abstract:isAvailable at the file app/code/core/Mage/Payment/Model/Method/Abstract.php

如果你将背信弃你的支付方法,你将不得不按照你的愿望,将“1”现场“活跃”用于储存观点或网站,或默认。

这里,“组合文件系统”的一个实例是,贵方付款模块。

<config>
   <sections>
    <payment translate="label" module="payment">

        <tab>sales</tab>

        <show_in_default>1</show_in_default>
        <show_in_website>1</show_in_website>
        <show_in_store>1</show_in_store>
        <groups>
            <yourpaymentname translate="label">

                <show_in_store>1</show_in_store>
                <fields>
                    <active translate="label">
                        <label>Enabled</label>
                        <frontend_type>select</frontend_type>
                        <source_model>adminhtml/system_config_source_yesno</source_model>
                        <sort_order>1</sort_order>
                        <show_in_default>1</show_in_default>
                        <show_in_website>1</show_in_website>
                        <show_in_store>0</show_in_store>
                    </active>
            <yourpaymentname>
        </groups>
        ....
    </sales>
<sections>

2) The second solution can be done through the backend, the easiest way maybe, in the tab Advanced of the configuration page, at the bottom left of the configuration page. You will have a list of all enabled or disabled modules in your shop. You select which store view you want to display or not, in the store switcher, at the top left of the page then you choose which module to enable or not thanks to the drop down menu in front of each module name.

Hope it helps Regards

you could/should have a "active" field, in your system.xml, which d be a dropdown "yes/no", and then you can (des)active it for every website/store/store view.
Of course in some strategic points of your code you will check if it s active for this view :)
