我正在尝试将另一个标签添加到包含其他产品网格的类别编辑页面。我需要这样做，因为我想在每个类别页面中添加一个区域，其中包含在此网格中选择的产品。
任何人都可以帮我完成模块吗？或者是否有更容易或现有的模块来执行此操作？
PS：非常感谢完整的代码：）
这是我到目前为止的地方： 的等/ config.xml中

不知道您上传所有这些代码的目的。据我所知，它并没有提到你的问题。如果要添加新标签，请执行以下操作：
config.xml中
<adminhtml>
<events>
<adminhtml_catalog_category_tabs>
<observers>
<add_new_tab>
<type>singleton</type>
<class>company_module/observer</class>
<method>addNewCategoryTab</method>
</add_new_tab>
</observers>
</adminhtml_catalog_category_tabs>
</events>
</adminhtml>
型号/ Observer.php
class Company_Module_Model_Observer
{
public function addNewCategoryTab($observer)
{
$tabs = $observer->getTabs();
$tabs->addTab('prod', array(
'label' => Mage::helper('catalog')->__('Other Products'),
'content' => $tabs->getLayout()->createBlock(
'adminhtml/catalog_category_tab_product',
'category.product.grid'
)->toHtml(),
));
}
使用从adminhtml/catalog_category_tab_product扩展的块并使用您的重新_prepareCollection方法。 （别忘了把你的块放在createBlock方法中）
