magento主页中的特色产品未使用模块显示

我想在主页上展示特色产品。因此，我在app/code/local/FeaturedProduct/Catalog/block/Product/Featureed.php中创建了自定义模块和块文件

代码：

class FeaturedProduct_Catalog_Block_Product_Featured  extends Mage_Catalog_Block_Product_Abstract
{           

public function __construct()
{
    $this->setLimit(40);
    $sort_by = 'name';
    $this->setItemsPerRow(4);

    switch ($sort_by) {
        case 0:
            $this->setSortBy("rand()");
        break;
        case 1:
            $this->setSortBy("created_at desc");
        break;
        default:
            $this->setSortBy("rand()");     
    }
}
protected function _beforeToHtml()
{           
    $collection = Mage::getResourceModel('catalog/product_collection');
        $attributes = Mage::getSingleton('catalog/config')
            ->getProductAttributes();
        $collection->addAttributeToSelect($attributes)
            ->addMinimalPrice()
            ->addFinalPrice()
            ->addTaxPercents()
            ->addAttributeToFilter('featured_products', 1, 'left')
            ->addStoreFilter()
            ->getSelect()->order($this->getSortBy())->limit($this->getLimit());

        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($collection);
        $this->_productCollection = $collection;
    $this->setProductCollection($collection);
    return parent::_beforeToHtml();
}
}

在app/code/local/FeaturedProduct/Catalog/etc/config.xml中创建了一个配置文件

代码：

<!--?xml version="1.0" encoding="UTF-8"?-->
<config>
<modules>
<featuredproduct_catalog>
    <version>1.0.0</version>                        
</featuredproduct_catalog>
</modules>
<global>
<blocks>
    <featuredproducts>
        <class>FeaturedProduct_Catalog_Block</class>
    </featuredproducts>
</blocks>
</global>
<frontend>
<layout>
    <updates>
        <featuredproducts>
            <file>featuredproduct.xml</file>
        </featuredproducts>
    </updates>
</layout>
</frontend>
</config>

已在app/design/frontend/rwd/default/layout/featuredproduct.xml位置创建featuredproduct.xml

代码：

<!--?xml version="1.0" encoding="UTF-8"?-->
<layout version="0.1.0">
<cms_index_index translate="label">
    <reference name="content">
        <block type="featuredproducts/products_featured" name="featured_product_collection" template="catalog/product/featured.phtml">
            <action method="setColumnCount">
                <columns>4</columns>
            </action>
        </block>
    </reference>
</cms_index_index>
</layout>

创建了一个视图文件"app/design/frontend/rwd/default/template/controlog/product/featureed.phtml"

代码：

<?php if (($_products = $this->getProductCollection()) && $_products->getSize()): ?>
<div class="clear"></div>  
<div class="new_product_slider">
<div id="demo">
<div class="text_left"><?php echo Mage::helper('featuredproducts')->getConfigHeading();?></div>
<div class="text_right"> <?php echo $this->__('Fragtfri ved køb over 130 kr.')?> </div>
<div class="clear"></div>
<div id="owl-demo1" class="owl-carousel">

<?php $i=1; foreach ($_products->getItems() as $_product): ?>
   <?php if($i > 1 ) { $j=2;} else { $j=1;} ?>
       <div class="item">
<ul>
<li>

             <a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>" class="prod"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(183, 183) ?>" width="183" height="183" alt="<?php echo $this->htmlEscape($_product->getName()) ?>" /></a>
                  <div class="cover"
<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>" > <?php echo strip_tags(ucfirst($this->htmlEscape($_product->getName()))) ?></a></div>
<h4><?php echo $this->getPriceHtml($_product, true, '-new') ?></h4>
<aside class="læs_btn"><a href="<?php echo $_product->getProductUrl() ?>"><span><?php echo $this->__('Læs mere'); ?></span></a></aside>
                   <div class="clear"></div>
</li>
</ul>
</div>
                   <?php $i++; if($i%5==0) { $i=1; ?>
            <?php  } ?>

<?php  endforeach; ?>
   </div>
</div>
</div>

在Magento Backend中为Store Owner下拉菜单的Catalog Input Type中创建了一个具有yes/no属性的特色属性，然后将其包含在属性集中，并从Catalog->Manage Products中将一个产品指定为特色"yes"。

将此添加到主页cms

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

在我加载主页后，它什么也不显示。不知道我在哪里犯了错。我不想更改local.xml，所以采取了这个方法。我还需要做什么或创建其他文件吗？请帮忙。

编辑：

创建了模块配置文件app/etc/modules/FeaturedProduct_Catalog.xml，现在显示在admin-conf adva 中

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