Magento 无法在内容块中使用phtml模板两次

我想设置一个Magento页面，如下所示：

<h2>Title</h2>

{{block type="catalog/navigation" category_id="5" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}
<h2>Title</h2>

{{block type="catalog/navigation" category_id="9" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}
<h2>Title</h2>

{{block type="catalog/navigation" category_id="38" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}

$getImageUrl($category)

标题
{{block type=“catalog/navigation”category_id=“5”template=“/catalog/navigation/subcategory.phtml”}
标题
{{block type=“catalog/navigation”category_id=“9”template=“/catalog/navigation/subcategory.phtml”}
标题
{{block type=“catalog/navigation”category_id=“38”template=“/catalog/navigation/subcategory.phtml”}

我的问题是，我调用的模板在一个站点中只能使用一次。如果我想再叫一次，我会得到一张空白页

<div id="categories">

    <div class="col_full">

        <div class="products-grid row first last odd" >

            <?php

            function getImageUrl($category)

                $layer = Mage::getSingleton('catalog/layer');

                $layer->setCurrentCategory($cur_category);

                $url = $this->getCurrentCategory()->getImageUrl();

                return $url;

            };


            //Get the Current Category
            $category = $this->getData('category_id');
            $_maincategorylisting=Mage::getModel('catalog/category')->getCategories($category);


            // Iterate all categories in store

            foreach ($_maincategorylisting as $_category):


                // If category is Active

                if($_category->getIsActive()):


                    // Load the actual category object for this category

您在模板中定义了一个函数。函数只能定义一次

做对了™
不要使用函数。Magento的方法是定义扩展
Mage_Catalog_block_Navigation
的自己的块，并将函数作为方法添加到此块中，或者将函数移动到帮助器类中

快速而肮脏的解决办法
将函数创建为闭包而不是普通全局函数：

$getImageUrl = function($category) {
    // ...
}

这样称呼它：

<h2>Title</h2>

{{block type="catalog/navigation" category_id="5" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}
<h2>Title</h2>

{{block type="catalog/navigation" category_id="9" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}
<h2>Title</h2>

{{block type="catalog/navigation" category_id="38" template="/catalog/navigation/subcategorylisting-distinctive.phtml"}}

$getImageUrl($category)

我浏览了一下你的代码，它与你的问题无关，但我给你一个建议：不要在循环中使用
load（）
。迭代加载的类别集合，在循环中再次加载每个类别，在此循环中，对产品再次执行相同的操作。这是非常糟糕的表现。相反，请在集合上使用类似于
addAttributeToSelect
的方法，以确保您需要的所有内容都已在第一次加载（这是一个大型数据库查询，而不是每个类别加一个查询），非常感谢！事实证明，我并不需要整个函数。
