我不知道有一种方法可以轻松地从静态块中引用这些值。

相反，我建议您创建和使用一个小部件（在我看来，这是 Magento 最未充分利用的功能之一），它将提供一种更清洁、更可扩展的方式来实现这一点——尽管它确实需要更多的前期工作:)

请参阅下面的代码以获取 Magento 小部件的完整（简化）示例，它完全按照您从静态块中提出的要求：

应用程序/etc/modules/YourCompany_Categorywidget.xml

<config>
    <modules>
        <MyCompany_Categorywidget>
            <active>true</active>
            <codePool>community</codePool>
        </MyCompany_Categorywidget>
    </modules>
</config>

我希望图像也链接到类别，所以我添加了...

app/code/community/MyCompany/Categorywidget/Block/Catalog/Category/Info.php

public function getCategoryUrl()
{
    return $this->_category->getUrl();
}

app/design/frontend/base/default/template/categorywidget/info.phtml

<?php
$_categoryName = $this->getCategoryName();
$_categoryImage = $this->getCategoryImage();
$_categoryUrl = $this->getCategoryUrl();
?>

<div class="categoryinfo_block block">
    <p><strong><?php echo $_categoryName ?></strong></p>    
    <a href="<?php echo $_categoryUrl ?>" title="<?php echo $_categoryName ?>" alt="<?php echo $_categoryName ?>">
        <img src="<?php echo $_categoryImage ?>" alt="<?php echo $_categoryName  ?>" />
    </a>
</div>

如果这对其他人有帮助？
