Overriding CsMarketplace account controller with a custom controller

问题

After reading & researching a lot i am asking this question today, lot of code available to override core magento files but not magento plugin files.

I have installed CsMarketplace plugin to my website for vendor management.

I want to override the vendor - register function to write my custom code which needs to work just after vendor is successfully registered.

Need to override: function createPostAction(); in file mypoject/app/code/local/Ced/CsMarketplace/controllers/AccountController.php

File 1: mypoject/app/code/local/Core/Ced/CsMarketplace/controllers/AccountController.php

require_once 'app/code/local/Ced/CsMarketplace/controllers/AccountController.php';

class Core_Ced_CsMarketplace_AccountController extends Ced_CsMarketplace_Controller_AbstractController {

/**
 * Create customer account action
 */
  public function createPostAction() {
    //my custom code
  }
}

File 2: mypoject/app/code/local/Core/Ced/CsMarketplace/etc/config.xml

<?xml version="1.0"?>
<config>
<modules>
    <Core_Ced_CsMarketplace>
        <version>1.0</version>
    </Core_Ced_CsMarketplace>
</modules>
<frontend>
    <routers>
        <CsMarketplace>
            <args>
                <modules>
                    <Core_Ced_CsMarketplace before="Ced_CsMarketplace">Core_Ced_CsMarketplace</Core_Ced_CsMarketplace>
                </modules>
            </args>
        </CsMarketplace>
    </routers>
</frontend>
</config>

File 3: mypoject/app/etc/modules/Core_All.xml

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

回答1:

Your controller is incorrectly placed in the filesystem. Magento always assumes that controllers located somewhere under a controllers directory which is itself exactly inside just a Namespace + Modulename folder, e.g.

app/code/[codepool]/[Namespace]/[Modulename]/controllers/ # I previously missed the codepool, because Magento 2 :-)

You are trying to get the system to locate controllers in a location where it by design cannot locate them.

(edit based on OP comment)

Controllers need two levels of depth (namespace + module name). The following won't work:

app/code/local/Namespace/controllers
app/code/local/Namespace/Modulename/SomeOtherFolder/controllers

In your case, you may choose CustomCed as your namespace, giving:

app/code/local/CustomCsd/CsMarketplace/controllers/AccountController.php

In there you will override createPostAction().

Also, depending on what you are doing, you could possibly use one of the dynamic events which exist around controller action dispatching.
