Magento列出特卖产品的方法_magento教程_php教程

有些Magento客户想要在首页显示特卖产品，或者有时想要在某个分类中筛选特卖产品。在这篇magento教程中，我将写到两种列出特卖产品的方法：

Magento首页作为列表显示；
在产品列表页通过筛选器显示；

让我们开始吧！

静态CMS页面

使用后台管理员上传一个.phtml文件是一个将特卖产品显示在某个页面的快速方法。用这个方法你将不能使用分页和导航。如果你喜欢这些功能，我推荐这篇文章的第二部分。

用以下内容创建一个新的CMS page

{{block type="catalog/product_list" template="inchoo/onsale/sale.phtml"}}

还有一个排列你产品的模版

app/design/frontend/default/YOUR_THEME/template/alwayly/onsale/sale.phtml

<?php
    $_productCollection = Mage::getModel('catalog/product')->getCollection();
    $_productCollection->addAttributeToSelect(array(
                                   'image',
                                   'name',
                                   'short_description'
                                              ))
                        ->addFieldToFilter('visibility', array(
                                    Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH,
                                    Mage_Catalog_Model_Product_Visibility::VISIBILITY_IN_CATALOG
                            )) //showing just products visible in catalog or both search and catalog
                        ->addFinalPrice()
//                        ->addAttributeToSort('price', 'asc') //in case we would like to sort products by price
                        ->getSelect()
                        ->where('price_index.final_price < price_index.price')
//                        ->limit(30) //we specify how many products we want to show on this page
//                        ->order(new Zend_Db_Expr('RAND()')) //in case we would like to sort products randomly
                        ;

    Mage::getModel('review/review')->appendSummary($_productCollection);
    $_helper = $this->helper('catalog/output');
?>

<?php if(!$_productCollection->count()): ?>
    <p class="note-msg"><?php echo $this->__('There are no products matching the selection.') ?></p>
<?php else: ?>
    <div class="category-products">
        <?php // Grid Mode ?>
        <?php $_collectionSize = $_productCollection->count() ?>
        <?php $_columnCount = $this->getColumnCount(); ?>
        <?php $i=0; foreach ($_productCollection as $_product): ?>
        <?php if ($i++%$_columnCount==0): ?>
            <ul class="products-grid" style="padding:0; list-style: none">
        <?php endif ?>
            <li class="item<?php if(($i-1)%$_columnCount==0): ?> first<?php elseif($i%$_columnCount==0): ?>

                <?php if($_product->getRatingSummary()): ?>
                    <?php echo $this->getReviewsSummaryHtml($_product, 'short') ?>
                <?php endif; ?>
                <?php echo $this->getPriceHtml($_product, true) ?>
                <div class="actions">
                    <?php if($_product->isSaleable()): ?>
                        <button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-

echo $this->__('Add to Cart') ?></span></span></button>
                    <?php else: ?>
                        <p class="availability out-of-stock"><span><?php echo $this->__('Out of stock') ?

                    <?php endif; ?>
                    <ul class="add-to-links">
                        <?php if ($this->helper('wishlist')->isAllow()) : ?>
                            <li><a href="<?php echo $this->helper('wishlist')->getAddUrl($_product) ?>"

                        <?php endif; ?>
                        <?php if($_compareUrl=$this->getAddToCompareUrl($_product)): ?>
                            <li><span class="separator">|</span> <a href="<?php echo $_compareUrl ?

                        <?php endif; ?>
                    </ul>
                </div>
            </li>
            <?php if ($i%$_columnCount==0 || $i==$_collectionSize): ?>
            </ul>
        <?php endif ?>
        <?php endforeach ?>
        <script type="text/javascript">decorateGeneric($$('ul.products-grid'),

    </div>
<?php endif; ?>

完成！尝试一下，然后访问你的CMS页面。你将看到带有特价的产品以列表的形式显示出来，就像这样：

修改一下以后，你也可以以网格的形式展示产品。

产品列表中的筛选器

一个集合在被读入模版前，Magento会使用筛选器并读取到分层导航。这就是我们要重写 _getProductCollection方法的原因，这样我们就能在集合被读取前使用自定义的筛选器。让我们扩展Mage_Catalog_Product_List类和渲染我们的块来替换分类列表中默认的筛选器。

让我们注册这个模型。根据作用，我们给它命名"Alwayly/Onsale"

app/etc/modules/Alwayly_Onsale.xml


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

接着配置我们的模型。我们将用到块(block)，助手(helper)并对我们模版的布局进行一点修改。

app/code/local/Inchoo/Onsale/etc/config.xml


<?xml version="1.0"?>
<config>
    <modules>
        <Alwayly_Onsale>
            <version>1.0.0.3</version>
        </Alwayly_Onsale>
    </modules>
    <global>
        <blocks>
            <alwayly_onsale>
                <class>Alwayly_Onsale_Block</class>
            </alwayly_onsale>
        </blocks>
        <helpers>
            <alwayly_onsale>
                <class>Alwayly_Onsale_Helper</class>
            </alwayly_onsale>
        </helpers>
    </global>
    <frontend>
        <layout>
            <updates>
                <onsale>
                    <file>alwayly/onsale.xml</file>
                </onsale>
            </updates>
        </layout>
    </frontend>
</config>

现在，注册一个包含getOnSaleUrl和getNotOnSaleUrl方法的助手。这两个方法将被用来获取我们复选框中链接的地址。我们将添加一个新的变量-"Sale"到网址。当sale等于1的时候，我们将显示特卖的产品，如果没有被设置就会显示这个类中的所有产品。

app/code/local/Inchoo/Onsale/Helper/Data.php

<?php
class Alwayly_Onsale_Helper_Data extends Mage_Core_Helper_Abstract
{
    public function getOnSaleUrl()
    {
        $url = Mage::getUrl('', array(
            '_current' => true,
            '_use_rewrite' => true,
            '_query' => array(
                'sale' => 1,
                'p' => NULL
            )
        ));
 
        return $url;
    }
 
    public function getNotOnSaleUrl()
    {
        $url = Mage::getUrl('', array(
            '_current' => true,
            '_use_rewrite' => true,
            '_query' => array(
                'sale' => NULL,
                'p' => NULL
            )
        ));
 
        return $url;
    }
}

接着让我们创建我们的块。我们将从Mage_Catalog_Block_Product_List扩展我们的类并添加 _getProductCollection方法。

app/code/local/Alwayly/Onsale/Block/Catalog/Product/List.php


<?php
class Alwayly_Onsale_Block_Catalog_Product_List extends Mage_Catalog_Block_Product_List
{
    protected function _getProductCollection()
    {
        if (is_null($this->_productCollection)) {
            $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()) {
                    // show products from this category
                    $this->setCategoryId(current($categories->getIterator()));
                }
            }
 
            $origCategory = null;
            if ($this->getCategoryId()) {
                $category = Mage::getModel('catalog/category')->load($this->getCategoryId());
                if ($category->getId()) {
                    $origCategory = $layer->getCurrentCategory();
                    $layer->setCurrentCategory($category);
                    $this->addModelTags($category);
                }
            }
            $this->_productCollection = $layer->getProductCollection();
 
//                inchoo start
            $param = Mage::app()->getRequest()->getParam('sale');
            if(isset($param) && $param==='1'){
                $this->_productCollection
                    ->addFinalPrice()
                    ->getSelect()
                    ->where('price_index.final_price < price_index.price');
            }
//                inchoo end
 
            $this->prepareSortableFieldsByCategory($layer->getCurrentCategory());
 
            if ($origCategory) {
                $layer->setCurrentCategory($origCategory);
            }
        }
 
        return $this->_productCollection;
//            return parent::_getProductCollection();
    }
}

我们还要在工具栏中添加一个复选框来让顾客筛选特卖产品。打开我们的toolbar.phtml文件。

最后，创建我们的布局文件来让Magento来使用我们的toolbar.phtml。

app/design/frontend/default/YOUR_THEME/layout/alwayly/onsale.xml


<?xml version="1.0"?>
 
<layout version="0.1.0">

                    <block type="catalog/product_list_toolbar" name="product_list_toolbar" template="inchoo/onsale/toolbar.phtml">
                        <block type="page/html_pager" name="product_list_toolbar_pager"/>
 
                        <!-- The following code shows how to set your own pager increments -->
