how to redirect referer page after login in magento


>> Only admin setting (step 1) needed to redirect customer after login. Using this I'm showing how will you restrict a page only for registered customer. If someone click the url www.example.com/restricted_page.html, it'll redirect to login page. Then after login it should redirect back to the www.example.com/restricted_page.html.
Here's how I did it :

    Step 1: Go to Admin => System => Configuration => Customer Configuration => Login Options => "Redirect Customer to Account Dashboard after Logging in" set it "No".
 
    Step 2: If you're using a module page then you've the controller Action method like:
  
            public function indexAction()
            {
                // use here to restrict the page //
                if(!Mage::helper('customer')->isLoggedIn()){
                    Mage::getSingleton('customer/session')->setBeforeAuthUrl('Restricted Page Url');
                       $this->_redirect('customer/account/login');
                }
                //        End your addition //

              
                $this->loadLayout();   
                $this->renderLayout();
            }
            you can use one of this code to redirect:
 
            Mage::getSingleton('customer/session')->setBeforeAuthUrl('Restricted Page Url');
            $this->_redirect('customer/account/login');
         
                                OR
                             
            $this->_redirect('customer/account/login/referer/'.Mage::helper('core')->urlEncode('Restricted Page Url'));
          
    Step 3: (optional) If you're using a cms page then follow this step:
          
            In your admin CMS section include a phtml page and write the below code at the top of the page:
          
            if(!Mage::helper('customer')->isLoggedIn()){
                Mage::getSingleton('customer/session')->setBeforeAuthUrl('Restricted Page Url');
                $this->_redirect('customer/account/login');
            }
          
>> Now if you want to use the login url inside a page with referer url follow this:
      
    <?php $referer = Mage::helper('core')->urlEncode(Mage::helper('core/url')->getCurrentUrl()); ?>
    <a href="<?php echo Mage::getUrl('customer/account/login', array('referer' => $referer)) ?>">Login</a>

How to add multi-select attribute in Admin product Grid view


Here I've shown a multi-select attribute named "brand".

>> In admin Grid.php find the method "_prepareColumns()" add the following code:

        $attribute = Mage::getModel('eav/config')->getAttribute('catalog_product', 'brand');        // attribute code here
        foreach ( $attribute->getSource()->getAllOptions(true, true) as $option)
        {
            if($option['value'] != '')
            $valArr[$option['value']] =  $option['label'];
        }
        // above code will use to show the dropdown
       
        $this->addColumn('brand',
            array(
                'header'=> Mage::helper('catalog')->__('Brands'),
                'width' => '60px',
                'index' => 'brand',
                'type'  => 'options',
                'options' => $valArr,
                'renderer'  => 'Mage_Adminhtml_Block_Catalog_Product_Renderer_Brands', // Will have to create the renderer.
                'filter_condition_callback' => array($this, '_filterBrandCondition')
        ));
       
        Then in this page you need to define the method "_filterBrandCondition" to filter with selected item.
       
        protected function _filterBrandCondition($collection, $column)
        {
            if (!$value = $column->getFilter()->getValue()) {
                return;
            }
            $this->getCollection()->addFieldToFilter('brand', array('finset' => $value));
        }
       
       
>> Now create the Brands.php file in code/local/Mage/Adminhtml/Block/Catalog/Product/Renderer directory and use the following code:

        class Mage_Adminhtml_Block_Catalog_Product_Renderer_Brands extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
        {
            public function render(Varien_Object $row)
            {
                $brands = explode(',',$row->getBrand());
                $html = "";
                if(count($brands)>0)
                {
                    $html ="<ul>";
                    foreach($brands as $value)
                    {
                        $_productModel = Mage::getModel('catalog/product');
                        $attribute = $_productModel->getResource()->getAttribute("brand");
                        if ($attribute ->usesSource()) {
                            $html .= "<li>".$attribute ->getSource()->getOptionText("$value")."</li>";
                        }
                    }
                    $html .= "</ul>";
                }
                return $html ;
            }
        }
