Magento 扩展模块 adminhtml 表单

Question

我正在尝试扩展我正在使用的模块，以便可以在 CMS 中的表单中添加额外的文本输入字段。构建 CMS 表单的模块文件位于以下位置 /app/code/community/Zeon/Manufacturer/Block/Adminhtml/Manufacturer/Edit/Tab/Form.php。这个文件的内容是这样读取的：

class Zeon_Manufacturer_Block_Adminhtml_Manufacturer_Edit_Tab_Form extends Mage_Adminhtml_Block_Widget_Form
    implements Mage_Adminhtml_Block_Widget_Tab_Interface
{
//code in here
}

我已经创建了我的自定义模块并在我的配置文件中有以下内容

<global>
    <blocks>
        <adminhtml>
            <rewrite>
                <manufacturer_edit_tab_form>MyModule_ZeonExt_Block_Adminhtml_Manufacturer_Edit_Tab_Form</manufacturer_edit_tab_form>
            </rewrite>
        </adminhtml>
    </blocks>
</global>

我的 Form.php 中有以下内容：

class MyModule_ZeonExt_Block_Adminhtml_Manufacturer_Edit_Tab_Form extends Zeon_Manufacturer_Block_Adminhtml_Manufacturer_Edit_Tab_Form {
//edited code in here
}

我已经很轻松地扩展了核心课程，但我似乎无法让上述工作正常进行，有人可以提供任何建议吗？

试试这个：

<global>
    <blocks>
        <zeon_manufacturer>
            <rewrite>
                <adminhtml_manufacturer_edit_tab_form>MyModule_ZeonExt_Block_Adminhtml_Manufacturer_Edit_Tab_Form</adminhtml_manufacturer_edit_tab_form>
            </rewrite>
        </zeon_manufacturer>
    </blocks>
</global>

或

<global>
    <blocks>
        <manufacturer>
            <rewrite>
                <adminhtml_manufacturer_edit_tab_form>MyModule_ZeonExt_Block_Adminhtml_Manufacturer_Edit_Tab_Form</adminhtml_manufacturer_edit_tab_form>
            </rewrite>
        </manufacturer>
    </blocks>
</global>
