magento - 覆盖已经存在的 magento 模块 adminhtml 块

Question

我试图在 Amasty shopby 模块中再添加一个自定义字段。为此，我需要覆盖 adminhtml 表单。我为此创建了模块，但这并没有覆盖现有模块。我必须覆盖“Amasty_Shopby_Block_Adminhtml_Filter_Edit_Tab_General”类。这是我的代码。

我的公司_我的模块.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mycompany_Mymodule>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Amasty_Shopby />
                <Amasty_Base />
            </depends>
        </Mycompany_Mymodule>
    </modules>
</config>

我的公司/我的模块/etc/config.xml

您现在要覆盖的不是 Amasty 块，而是adminhtml/filter_edit_tab_general。因此，要重写Amasty_Shopby_Block_Adminhtml_Filter_Edit_Tab_General您需要以下配置：

<global>
    <blocks>
        <amshopby>
            <rewrite>
                <adminhtml_filter_edit_tab_general>Mycompany_Mymodule_Block_Adminhtml_Filter_Edit_Tab_General</adminhtml_filter_edit_tab_general>
            </rewrite>
        </amshopby>
    </blocks>
</global>
