Magento扩展Module adminhtml表单

Question

我正在尝试扩展我正在使用的模块，这样我就可以在CMS中的表单中添加一个额外的文本输入字段。生成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。此文件的内容如下：

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包含以下内容：

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

我已经很容易地扩展了核心课程，但是我似乎无法完成上面的工作，有人能给我一些建议吗？

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>
