How to show featured products on home page in magento?

If you want to show featured products on home page in magento so here is code for you...

IF you still have not add featured attribute in magento so first of all you have to add arrtibute in Manage Attributes

Step 1: Create new Featured attribute

Create a new attribute by going to Catalog > Attributes > Manage Attributes > Add New Attribute.
Attribute Properties

• Attribute Identifier: featured
• Scope: Store View
• Catalog Input Type for Store Owner: Yes/No
• Unique Value (not shared with other products): No
• Values Required: No
• Input Validation for Store Owner: None
• Apply To: All Product Types

Front End Properties

• Use in quick search: No
• Use in advanced search: Yes
• Comparable on Front-end: No
• Use In Layered Navigation (Can be used only with catalog input type ‘Dropdown’): No
• Visible on Catalog Pages on Front-end: Yes

Manage Label/Options

Default: Featured Product

Save the new attribute and go to Catalog ? Attributes ? Manage Attributes Sets to add the attribute to the default feature set. I mean to say put the attribute from right side and place it in left side where you want to show this attribute during the add prduct

Step 2: Create new block class that will instantiate the featured product

Create a new file, and directories: app/code/local/Company/Catalog/Block/Product/Featured.php

<?php
class Company_Catalog_Block_Product_Featured extends Mage_Catalog_Block_Product_Abstract

     * Default toolbar block name

            $layer = $this->getLayer();
            /* @var $layer Mage_Catalog_Model_Layer */
            if ($this->getShowRootCategory()) {
              $this->setCategoryId(Mage::app()->getStore()->getRootCategoryId());

            }

            // if this is a product view page
            if (Mage::registry('product')) {
                // get collection of categories this product is associated with
                $categories = Mage::registry('product')->getCategoryCollection()
                    ->setPage(1, 1)
                    ->load();
                // if the product is associated with any category
                if ($categories->count()) {

                }
            }

           $this->_productCollection = $layer->getProductCollection()->addFieldToFilter(array(array('attribute' => 'featured', 'eq' => true),));

            $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());

            if ($origCategory) {

        if ($layer) {
            return $layer;
        }
        return Mage::getSingleton('catalog/layer');
    }

    /**
     * Retrieve loaded category collection

    /**

     */
    protected function _beforeToHtml()
    {

        $this->setChild('toolbar', $toolbar);
        Mage::dispatchEvent('catalog_block_product_list_collection', array(

                }
            }
        }

        return $this;
    }
} 

?>

Step 3: Extend Mage_Page_Block_Html

Create a new file, and directories: app/code/local/Company/Page/Block/Html.php

<?php

class Company_Mage_Page_Block_Html extends Mage_Page_Block_Html
{
public function getFeaturedProductHtml()
{
return $this->getBlockHtml('product_featured');
}
}
?>

Step 4: Add This blocks to the app/etc/local.xml

<blocks>

<catalog>

<rewrite>

<product_featured>Company_Catalog_Block_Product_Featured</product_featured>

</rewrite>

</catalog>

</blocks>

after the <config><global> block.

Step 5: echo featured products HTML

Place the following code to the file: app/design/frontend/default/default/template/catalog/product/featured.phtml

<style>
.view-mode {display:none;}
</style>
<div style="float:left; width:100%; padding-left:0px; min-height:500px;"><div style="width:100%; float:left;">
      <p><?php
    $_productCollection=$this->_getProductCollection();
    $_helper = $this->helper('catalog/output');
?>
 
<?php // Product Image ?>
 <?php echo $this->getToolbarHtml() ?>
</p>
<?php foreach($_productCollection as $_product) {
$sortdesc = strlen($this->htmlEscape($_product->getShortDescription()));
$title = strlen($this->htmlEscape($_product->getName()));
?>
    <div style="width:200px; margin:15px; float:left;">
          <div style="float: left; width:200px;"> <a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" class="product-image"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(200); ?>" width="200" height="200" alt="<?php echo $this->htmlEscape($this->getImageLabel($_product, 'small_image')) ?>" /></a>&nbsp;&nbsp;
           </div>
<div style="float: left; width:100%;">
          <div style="float: left;"><p style="margin-bottom:1px;"> <a href="<?php echo $_product->getProductUrl() ?>">
          <?php echo substr($this->htmlEscape($_product->getName()),0,12); ?><?php if($title>12){ echo "..."; }?>
         
          </a></p>
          <p style="font-size:14px;"><?php echo substr($this->htmlEscape($_product->getShortDescription()),0,15); ?><?php if($sortdesc>15){ echo "..."; }?></p></div>
 <div style="float: right;">
           <p> <a href="<?php echo $_product->getProductUrl() ?>"><img alt="view Details" src="<?php echo $this->getSkinUrl('images/view.jpg') ?>"></a></p></div>
           </div></div>
           <?php } ?>
         
</div> </div>
<?php // Product Image ?>
 <?php echo $this->getToolbarHtml() ?>
</p>

Step 6: Add Featured Products block to the frontpage

As the last step, you have to place featured product box to the frontpage. So, go to Magento administration to CMS> Manage Pages and select home page (or any other if you wish to place featured products in separate page)
Place the following line in Content area:

{{block type="catalog/product_featured" name="product_featured" as="product_featured" template="catalog/product/featured.phtml"}}

After this delete your cache and flush all type of cache from admin and ftp , delete session and refresh the page hope this will work fine.

its really  works i used it many times...... :)
