Question

我想扩展一个magento核心类并覆盖其中的一个函数。社区扩展使用相同的类并覆盖我的代码，但通常本地扩展会覆盖社区，或者我错了？

这是我的扩展程序在干净安装中正常工作：

应用程序的/ etc /模块/ NameSpace_OutOfStockLabel.xml

<?xml version="1.0"?>
<config>
    <modules>
        <NameSpace_OutOfStockLabel>
            <active>true</active>
            <codePool>local</codePool>
        </NameSpace_OutOfStockLabel>
    </modules>
</config>

应用程序/代码/本地/名称空间/ OutOfStockLabel的/ etc / config.xml中

<?xml version="1.0"?>
<config>
    <modules>
        <NameSpace_OutOfStockLabel>
            <version>0.0.1</version>
        </NameSpace_OutOfStockLabel>
    </modules>
    <global>
        <blocks>
            <catalog>
                <rewrite>
                    <product_view_type_configurable>NameSpace_OutOfStockLabel_Block_Configurable</product_view_type_configurable>
                </rewrite>
            </catalog>
        </blocks>
    </global>
</config>

应用程序/代码/本地/名称空间/ OutOfStockLabel /砌块/ Configurable.php

Magento中有一个模块配置，它将帮助解决冲突。您可以在Extension Y的模块/扩展等中使用此配置模块，您也可以在其中定义Extension Y的加载顺序。您需要能够在扩展X之后加载扩展Y.作为Magento电子商务网站开发人员，当您是能够做到这一点，你可以很好地解决冲突。将下面提到的代码写入扩展Y的app / etc / modules / extension_Y.xml中的depends模块配置：
