Magento 1.6.2 - 覆盖联系人控制器的问题

Question

好的，所以我设置了一个新模块来覆盖联系人控制器，以便我可以向它添加新闻通讯注册选项。我的设置如下：

/app/code/local/MyNamespace/ContactsPlus/controllers/Contacts/IndexController.php：

<?php
# Controllers are not autoloaded so we will have to do it manually:
require_once 'Mage/Contacts/controllers/IndexController.php';
class MyNameSpace_ContactsPlus_Contacts_IndexController extends Mage_Contacts_IndexController
{
    # Overloaded indexAction
    public function indexAction() {
        # Just to make sure
        error_log('Yes, I did it!');
        parent::indexAction();
    }
}

/app/code/local/MyNamespace/ContactsPlus/etc/config.xml：

<?xml version="1.0"?>
<config>
    <modules>
        <mynamespace_ContactsPlus>
            <version>0.1.0</version>
        </mynamespace_ContactsPlus>
    </modules>
    <global>
        <rewrite>
            <mynamespace_contactsplus_contacts_index>
                <from><![CDATA[#^/contacts/index/#]]></from>
                <to>/contactsplus/contacts_index/</to>
            </mynamespace_contactsplus_contacts_index>
            <mynamespace_contactsplus_contacts_index>
                <from><![CDATA[#^/contacts/#]]></from>
                <to>/contactsplus/contacts_index/</to>
            </mynamespace_contactsplus_contacts_index>            
        </rewrite>
    </global>
    <frontend>
        <routers>
            <mynamespace_contactsplus>
                <use>standard</use>
                <args>
                    <module>mynamespace_ContactsPlus</module>
                    <frontName>contactsplus</frontName>
                </args>
            </mynamespace_contactsplus>
        </routers>
    </frontend>    
</config>

/app/etc/modules/MyNamespace_All.xml：

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

该模块出现在管理模块列表中，并且在我的 /contacts/ 页面上产生了以下错误：

Fatal error: Call to a member function setFormAction() on a non-object in /srv/www/foo.com/app/code/core/Mage/Contacts/controllers/IndexController.php on line 54 

就是这一行：

        $this->getLayout()->getBlock('contactForm')->setFormAction( Mage::getUrl('*/*/post') );

我不确定从这里去哪里，猜测是它无法对从 Mage::getUrl('//post' 返回的任何内容设置表单操作) 但我正抓着稻草。

任何建议的帮助将不胜感激！

好的，经过大量研究、帮助和普遍的挫败感，这就是我如何让它工作的：

首先，我的模块目录设置如下（注意目录上的大写）：

/app/code/local/MyNamespace/ContactsPlus/etc/

• config.xml

/app/code/local/MyNamespace/ContactsPlus/controllers/

• IndexController.php

/app/code/local/MyNamespace/ContactsPlus/Helper/

• 数据.php

现在是配置文件：

/app/code/local/MyNamespace/ContactsPlus/etc/config.xml：

<?xml version="1.0"?>
<config>
    <modules>
        <MyNameSpace_ContactsPlus>
            <version>0.1.0</version>
        </MyNameSpace_ContactsPlus>
    </modules>
    <frontend>
        <routers>

        <!-- Creates route to my module via /contactsplus/ - I used this for testing -->
            <contactsplus>
                <use>standard</use>
                <args>
                    <module>MyNameSpace_ContactsPlus</module>
                    <frontName>contactsplus</frontName>
                </args>
            </contactsplus>

        <!-- Sets Mage_Contacts route to MyNameSpace_ContactsPlus -->              
            <contacts>
                <args>
                    <modules>
                        <MyNameSpace_ContactsPlus before="Mage_Contacts">MyNameSpace_ContactsPlus</MyNameSpace_ContactsPlus>
                    </modules>
                </args>
            </contacts> 
        </routers>
    <!-- Sets layout config file (essential for this to work) -->   
        <layout>
            <updates>
                <contactsplus>
                    <file>contactsplus.xml</file>
                </contactsplus>
            </updates>
        </layout>        
    </frontend>
    <global>
    <!-- Sets a helper class for the module, when overriding contacts this is also essential. -->   
        <helpers>
            <contactsplus>
                <class>MyNameSpace_ContactsPlus_Helper</class>
            </contactsplus>
        </helpers>        
    </global>
</config>

/app/code/local/MyNamespace/ContactsPlus/controllers/Contacts/IndexController.php：

<?php
# Controllers are not autoloaded so we will have to do it manually:
require_once 'Mage/Contacts/controllers/IndexController.php';
class MyNameSpace_ContactsPlus_IndexController extends Mage_Contacts_IndexController
{
    # Overloaded indexAction
    public function indexAction() {
        # Just to make sure
        //die('Yes, I did it!');
        parent::indexAction();
    }
}

/app/design/frontend/mythemepackage/mytheme/layout/contacts.xml：

    <contacts_index_index translate="label">

</layout>

         --></reference>
    </default>
    <contactsplus_index_index translate="label">
        <label>Contact Us Form</label>

        </reference>
    </contactsplus_index_index>

</layout>

我也复制了一份/app/design/frontend/mythemepackage/mytheme/template/contacts/form.phtml 放到/app/design/frontend/mythemepackage/mytheme/template/contactsplus/ 然后修改以满足我的要求。

在此过程中我发现特别有用的资源是 google、IRC #magento 和

希望这可以在某个时候对其他人有所帮助。

现在是在我的新表单中添加时事通讯注册选项！
