Magento 在捆绑项目中添加另一个新字段

Question

我想在捆绑项目的默认标题下方添加新的文本列。 当我创建一个新的捆绑产品时，我需要添加一个额外的字段 我希望在默认标题下方的新文本字段中添加描述。 请帮助。任何帮助将不胜感激。

Answer 1

为了在每个bundle option 中添加一个新的description field，您需要创建一个模块。简而言之，您的模块将执行以下功能。

1. 创建一个新表以保存我们的 description field 以用于捆绑选项。

2. 当产品保存时，它会更新我们的表格进行必要的更改。

考虑到这一点，让我们创建我们的模块。让我们的模块为Programmerrkt_Customfieldinbundle

位置：app/code/local/Programmerrkt/Customfieldinbundle/etc/config.xml

<config>

    <Programmerrkt_Customfieldinbundle>

        </programmerrkt_customfieldinbundle>
    </blocks>
</global>
</config>

我们的配置文件包含有关我们将在其中存储捆绑描述的自定义表 catalog_product_bundle_option_description 的详细信息。它还定义了一个观察者，它在触发时会将更改保存到我们的自定义表中。

位置：app/etc/modules/Programmerrkt_Customfieldinbundle.xml

<config>
<modules>
    <Programmerrkt_Customfieldinbundle>
        <active>true</active>
        <codePool>local</codePool>
    </Programmerrkt_Customfieldinbundle>
</modules>
</config>

现在我们需要在管理端显示我们的描述字段。为此，我们需要编辑一个块，以呈现捆绑选项。该块是app/code/core/Mage/Bundle/Block/Adminhtml/Catalog/Product/Edit/Tab/Bundle/Option.php。我们需要更改此文件中的两个方法。 **只显示主要部分

这些方法是

1. __construct()

此方法用于定义用于选项内容呈现的自定义模板。使用它我们可以避免核心模板编辑。

1. getOption()

此方法用于将我们模块的数据包含到现有选项中。通过这种方法，magento 将显示已经创建的选项的集合描述。

注意：我只描述了我们模块的重要文件。我想，你们都知道如何在 Magento 中设置一个基本模块。

就是这样。你准备好了。清除缓存并加载捆绑产品。您可以在捆绑选项的标题字段下方看到一个文本区域。

如有任何疑问，请随时询问。
