Magento - 在自定义页面模板上使用 $this->getPriceHtml
我有一个滚动条，显示当前正在销售的一系列产品，我使用以下命令对其进行调用：
$todayDate = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->addAttributeToFilter('visibility', $visibility)
->setPageSize(4) // Only return 4 products
->addAttributeToFilter('special_from_date', array('date' => true, 'to' => $todayDate))
->addAttributeToFilter('special_to_date', array('or'=> array(
0 => array('date' => true, 'from' => $todayDate),
1 => array('is' => new Zend_Db_Expr('null')))
), 'left')
->addAttributeToSort('special_from_date', 'desc');
$_productCollection->load();
然后我运行 foreach 来获取各个产品：
foreach ($_productCollection as $_product)
一切正常，除了价格，我通常会使用它来调用
$this->getPriceHtml($_product, true)
但是这是给出的我一片空白。如果我执行 var_dump，我可以看到原价和特价都可用，那么为什么这不起作用呢？我在主页模板上使用完全相同的代码，通过主页 CMS 调用该代码，并且价格显示正常（常规价格划掉并显示特价）。
使用 $_product->getFinalPrice() 效果很好，但只给我最终的“特殊”价格，而不显示原始价格。
我是否可能在 xml 布局中遗漏了使用 getPriceHtml 显示价格所需的内容？
I have a scroller showing a collection of products currently on sale, which I call using the following:
$todayDate = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
$_productCollection = Mage::getResourceModel('reports/product_collection')
->addAttributeToSelect('*')
->addAttributeToFilter('visibility', $visibility)
->setPageSize(4) // Only return 4 products
->addAttributeToFilter('special_from_date', array('date' => true, 'to' => $todayDate))
->addAttributeToFilter('special_to_date', array('or'=> array(
0 => array('date' => true, 'from' => $todayDate),
1 => array('is' => new Zend_Db_Expr('null')))
), 'left')
->addAttributeToSort('special_from_date', 'desc');
$_productCollection->load();
I then run a foreach to get the individual products:
foreach ($_productCollection as $_product)
Everything works fine, except for the price, which I would usually call using
$this->getPriceHtml($_product, true)
However this is giving me a blank. If I do a var_dump I can see that both the original price and the special price are both available, so why isn't this working? I use exactly the same code on my homepage template, which I call through the homepage CMS, and the price is shown fine (with the regular price crossed out and special price shown).
Using $_product->getFinalPrice() works fine, but only gives me the final "special" price and doesn't show the original price.
Am I maybe missing something in my xml layout that's needed to show the prices using getPriceHtml?

我的同事建议使用这种 Magento 友好的方法在任何地方获取价格 html：
如果您已经在使用加载的产品，那么您不需要第一行，但是我的产品来自一个集合，所以这是必要的。
My colleague recommended using this Magento friendly method to get the price html anywhere:
If you're already working with a loaded product then you won't need the first line, however my product was from a collection so this was necessary.
问题在于
getPriceHtml()函数是在Mage_Catalog_Block_Product块中定义的，而不是在标准Mage_Core_Block_Template中定义的。您需要确保您的块扩展了 Product 块，或者您可以通过以下方式在布局中实现这一点：我还没有测试过，但它应该可以工作。
The issue is that
getPriceHtml()function is defined in theMage_Catalog_Block_Productblock, rather than the standardMage_Core_Block_Template. You need to ensure that your block extends the Product block, or you can achieve that in your layout by something like:I haven't tested that, but it should work.
您也可以尝试以下操作：
其中
$_product与产品对象相关。You could also try this:
Where
$_productrelates to the product object.要让 getPriceHtml() 函数在自定义块中正常工作，您需要做两件事
1) 创建块类型目录/产品
2) 将产品对象传递给 getPriceHtml() 函数
To get getPriceHtml() function work correctly in your custom block you need 2 things
1)Make your block type catalog/product
2)Pass the product object to getPriceHtml() function
