Custom Login page redirect

Question

I have created a custom login module which loads a page to be used by a particular customer group with its own URL trade/account/login. However, I've noticed that if a user tries to login with an incorrect username and password the page redirects back to the default customer/account/login URL.

Is there a way I can keep the customer on the same page if they enter the wrong login details?

I would like to keep them on trade/account/login instead of redirecting to the customer account login customer/account/login

So far I only have this in my controller which loads the customer login page and form this works fine but doesn't keep the user on the same page if they enter the wrong username or password

<?php


class Namespace_Customlogin_AccountController extends Mage_Core_Controller_Front_Action{

    public function LoginAction() {

      $this->loadLayout();
      $this->renderLayout();

    }
}

I'm looking into the AccountController.php but I cannot see where the redirect happens so would like to ask if anyone knows where I can override it in my module please?

Answer 1

It was quite simple in the end

<?php if ($this->helper('customer')->isLoggedIn()): ?>
<?php Mage::app()->getFrontController()->getResponse()->setRedirect(Mage::getUrl('customer/account'));?>
<?php else: Mage::getSingleton('customer/session')->setBeforeAuthUrl(Mage::helper('core/url')->getCurrentUrl()); ?>
<?php endif ?>

If the custom successfully logs in then redirect to the customer account page otherwise stay on the current URL

When a browser requests for a url like trade/account/login, magento will first look which module that uses trade as it's frontName. Now let us assume your custom module uses trade as it's front name.

Next parameter is account. Magento will use this to find corresponding controller file that has to process. So thus magento now looks for AccountController.php file in your module's controllers directory.

Next parameter is using to find the action. Here it is login. Hence Magento will look for a loginAction() in AccountController.php which resides in your module. (I can see you have used LoginAction(). It will not work for sure ).

When you submit a login credentials, it will post this data to another action that is defined in AccountController which is in your module. For an example, default AccountContoller in Mage_Customer uses logiPost action for this purpose. I assume in the similar way, your AccountController also holds a validation method. If it is not there, you need to create one. Let it be loginPost.

So in this case, first you need to refer your login form to this action. It will somewhat looks like this.

<form name="form_name" action="<?php echo $this->getUrl('trade/account/loginPost'); ?>">
      <!-- your form fields lives here -->
</form>

You have set url correctly.Now in your AccountController, you need to define loginPost action

File : app\code\<codePool>\Namespace\Modulename\controllers\AccountController.php

public function loginPostAction()
{
    $params = $this->getRequest()->getParams();
    //do your validation here
    if (<validation_fails>) {
          $this->_redirect('*/*/login'); // this will redirect to your login action
    }
}

As you can see redirectUrl() does the trick. It's parameter tells to magento, that we need to persist same current frontname and controller, but action should be login. Since current frontname and controllers are trade and account, it points towards your controller's login action

Use this data wisely and achieve your result. Happy debugging !
