只要加代码

 Mage::getSingleton(‘customer/session‘)->setBeforeAuthUrl(Mage::getUrl(‘*/*/*‘, array(‘_secure‘=>true)));或

     Mage::getSingleton(‘customer/session‘)->setBeforeAuthUrl(Mage::helper("core/url")->getCurrentUrl());

在之前的页面 就可以实现这个功能

  <!-- <?php //判断用户是否是登录用户，如果不是登录用户就跳转到登录页面，登录成就进入网站的页面?>-->

          <?php

          Mage::getSingleton(‘customer/session‘)->setBeforeAuthUrl($this->getRequest()->getRequestUri());  //save requested URL for later redirection

          if(!Mage::getSingleton(‘customer/session‘)->isLoggedIn()) {  // if not logged in

              header("Status: 301");

            //  header(‘Location: ‘.Mage::helper(‘core/url‘)->getHomeUrl(customer/account/login)) ;  // send to the login page

             header(‘Location:‘.Mage::getBaseUrl(‘web‘).‘index.php/customer/account/login/‘           ) ;

              exit;

          }

          ?>

magento在购物车中判断用户登录，如果没有登录就跳转到登录页面，红色字体代表新增代码

首先进入app/code/local/idev/onestepchekcout/controllers/indexcontroller.php文件

加上一个

if(Mage::getSingleton( ‘customer/session‘ )->isLoggedIn())

        {判断和

 else

        {       $redirect=Mage::getBaseUrl().‘customer/account/create/‘;

               Mage::app()->getFrontController()->getResponse()->setRedirect($redirect)->sendResponse();//这个是需要跳转到的登录页面或者是注册页面

        }

即可

放的位置代码如下：

 public function indexAction() {

        if(Mage::getSingleton( ‘customer/session‘ )->isLoggedIn())

        {

          $quote = $this->getOnepage()->getQuote();

          if (!$quote->hasItems() || $quote->getHasError()) {

              $this->_redirect(‘checkout/cart‘);

              return;

          }

          if (!$quote->validateMinimumAmount()) {

              $error = Mage::getStoreConfig(‘sales/minimum_order/error_message‘);

              Mage::getSingleton(‘checkout/session‘)->addError($error);

              $this->_redirect(‘checkout/cart‘);

              return;

          }

          $this->loadLayout();

          if(Mage::helper(‘onestepcheckout‘)->isEnterprise() && Mage::helper(‘customer‘)->isLoggedIn()){

              $customerBalanceBlock = $this->getLayout()->createBlock(‘enterprise_customerbalance/checkout_onepage_payment_additional‘, ‘customerbalance‘, array(‘template‘=>‘onestepcheckout/customerbalance/payment/additional.phtml‘));

              $customerBalanceBlockScripts = $this->getLayout()->createBlock(‘enterprise_customerbalance/checkout_onepage_payment_additional‘, ‘customerbalance_scripts‘, array(‘template‘=>‘onestepcheckout/customerbalance/payment/scripts.phtml‘));

              $rewardPointsBlock = $this->getLayout()->createBlock(‘enterprise_reward/checkout_payment_additional‘, ‘reward.points‘, array(‘template‘=>‘onestepcheckout/reward/payment/additional.phtml‘, ‘before‘ => ‘-‘));

              $rewardPointsBlockScripts = $this->getLayout()->createBlock(‘enterprise_reward/checkout_payment_additional‘, ‘reward.scripts‘, array(‘template‘=>‘onestepcheckout/reward/payment/scripts.phtml‘, ‘after‘ => ‘-‘));

              $this->getLayout()->getBlock(‘choose-payment-method‘)

              ->append($customerBalanceBlock)

              ->append($customerBalanceBlockScripts)

              ->append($rewardPointsBlock)

              ->append($rewardPointsBlockScripts)

              ;

          }

          $this->renderLayout();

        }

        else

        {       $redirect=Mage::getBaseUrl().‘customer/account/create/‘;

               Mage::app()->getFrontController()->getResponse()->setRedirect($redirect)->sendResponse();

        }

    }

判断用户是否从结算页面当中进入的，如果是从结算页面当中进入登录的或者是注册的那么需要进入下一步操作

  首先在form表单中加个<input name="xxx" value="xxxx" type="hidden"/>代码如下：

<form id="login-form" action="http://www.wellsupplier.com/index.php/customer/account/loginPost/" method="post">

              <input type="hidden" value="check-out" name="cart-name"/>

或者跳转到进入登录注册页面前一页

  <?php echo $currlink=substr($_SERVER[‘HTTP_REFERER‘],27); ?>

       <input type="hidden" value="<?php echo $currlink;?>" name="cart-name"/>

然后去loginPostAction方法中进行判断，代码路径D:\Program Files\wamp\www\focalpriced\app\code\core\Mage\Customer\controllers\accountcontrollers.php文件

然后找到public function loginPostAction()方法 ；

 public function loginPostAction()

    {            

    $chac=$this->getRequest()->getParam("cart-name");  //获取表单的传过来的值

        if ($this->_getSession()->isLoggedIn()) {

            $this->_redirect(‘*/*/‘);

            return;

        }

        $session = $this->_getSession();

        if ($this->getRequest()->isPost()) {

            $login = $this->getRequest()->getPost(‘login‘);

            if (!empty($login[‘username‘]) && !empty($login[‘password‘])) {

                try {

                    $session->login($login[‘username‘], $login[‘password‘]);

                    if ($session->getCustomer()->getIsJustConfirmed()) {

                        $this->_welcomeCustomer($session->getCustomer(), true);

                    }

                } catch (Mage_Core_Exception $e) {

                    switch ($e->getCode()) {

                        case Mage_Customer_Model_Customer::EXCEPTION_EMAIL_NOT_CONFIRMED:

                            $value = Mage::helper(‘customer‘)->getEmailConfirmationUrl($login[‘username‘]);

                            $message = Mage::helper(‘customer‘)->__(‘This account is not confirmed. <a href="%s">Click here</a> to resend confirmation email.‘, $value);

                            break;

                        case Mage_Customer_Model_Customer::EXCEPTION_INVALID_EMAIL_OR_PASSWORD:

                            $message = $e->getMessage();

                            break;

                        default:

                            $message = $e->getMessage();

                    }

                    $session->addError($message);

                    $session->setUsername($login[‘username‘]);

                } catch (Exception $e) {

                    // Mage::logException($e); // PA DSS violation: this exception log can disclose customer password

                }

            } else {

                $session->addError($this->__(‘Login and password are required.‘));

            }

        }

        if(isset($chac)){      //判断表单的值进行跳转

        $redirect=Mage::getBaseUrl().$chac;

         Mage::app()->getFrontController()->getResponse()->setRedirect($redirect)->sendResponse();

        } else  {

        $this->_loginPostRedirect();

        }

    }
