magento-静态块中的类别名称和图像? [英] magento - category name and image in static block?

问题描述

如何通过magento后端从magento的静态块中引用类别名称和图像?我正在运行1.7.

How can i reference category name and image from a static block in magento through the magento backend? I'm running 1.7.

推荐答案

我不知道可以从静态块中轻松引用这些值的方法.

I am not aware of a way in which you can easily reference these values from within a static block.

相反，我建议您创建和使用一个小部件(我认为是Magento最未被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此目的-尽管它确实需要做更多的工作:)

Instead, I would suggest you create and use a widget (one of the most underused features of Magento in my opinion) which will provide a much cleaner and more extendible way of achieving this - though it does require more work upfront :)

请参见下面的代码，以获取完整的(简化的)Magento小部件示例，该示例完全符合您在静态块中的要求:

Please see code below for a full (simplified) example of a Magento Widget which does exactly what you have asked from the static block:
