Question

I'm attempting to use multiple observer classes & modules for Magento, all of which are being put into app/code/local. These all work on my local workstation, but will NOT work when I copy them to production via FTP. I am going crazy trying to figure out what's going on. All of my code seems sound. Here's an example of an observer:

app/code/local/Mural/Pricing/Model/Observer.php

<?php 
class Mural_Pricing_Model_Observer {
    public function setMuralPricing($observer) {
        echo 'We did it!';
        die();
    } 
}

app/code/local/Mural/etc/config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mural_Pricing>
            <version>0.0.1</version>
        </Mural_Pricing>
    </modules>
    <global>
        <models>
            <Mural_Pricing>
                <class>Mural_Pricing_Model</class>
            </Mural_Pricing>
        </models>
    </global>
    <adminhtml>
        <events>
            <sales_quote_add_item>
                <observers>
                    <Mural_Pricing>
                        <class>mural_pricing/observer</class>
                        <method>setMuralPricing</method>
                    </Mural_Pricing>
                </observers>
            </sales_quote_add_item>
        </events>
    </adminhtml>
</config>

app/etc/modules/Mural_Pricing.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mural_Pricing>
            <codePool>local</codePool>
            <active>true</active>
            <depends>
                <Mage_Catalog />
            </depends>
        </Mural_Pricing>
    </modules>
</config>

Like I said, this works fine locally, but not in production, with several different observers & modules. Frustrating. Thank you in advance!

我注意到的第一件事是你的观察者声明是在观察到的事件上调用mural_pricing/observer::setMuralPricing()。

如果查看配置XML，您可以按照此XML将此模块中的模型注册为Mural_Pricing/...：

<models>
    <Mural_Pricing>
        <class>Mural_Pricing_Model</class>
    </Mural_Pricing>
</models>

Magento最佳实践似乎是对类别名使用全小写，因此我建议您将其更改为mural_pricing。如果您将观察者声明更改为使用大写的等效声明，它也会起作用。

另一方面，我并不认为您为此标记命名的内容确实很重要，但<Mural_Pricing>下面的<observers>标记应理想地代表观察者所做的简短描述（再次，不要认为实际上很重要 - 例如<mural_pricing_set_pricing>。

最后，必须说明 - 确保您已正确清除缓存以重新解析XML配置。如果您在生产中使用Redis或其他缓存架构vs dev / staging / local，那么您可能忘记以不同的方式清除缓存，而不是在本地执行操作。

最终，除了类别名和观察者声明中的大小写差异之外，您的模块看起来很好。
