我在Magento中遇到两次障碍了吗?

问题描述

我试图在主页上创建产品块，在该产品中，我将page.xml复制到主题的布局文件夹中，并进行了修改

I am trying to create product block on home page where in I copied page.xml to my theme's layout folder and modified it like

<page_two_columns_left translate="label">
<label>All Two-Column Layout Pages (Left Column)</label>
<reference name="root">
    <action method="setTemplate"><template>page/2columns-left.phtml</template></action>
    <!-- Mark root page block that template is applied -->
    <action method="setIsHandle"><applied>1</applied></action>
</reference>
<reference name="content">
   <block type="core/template" name="mycategories" output="toHtml" template="sweet/sweet.phtml"/>
 </reference>

在这里，我期望主页中间出现一个块，但我得到了，但除此之外，我在主页底部又得到了一个块(与sweet.phtml块相同).页脚链接下方.谁能告诉我是什么问题.

Here I was expecting one one block in the middle of my Home page and i am getting that but in addition to this i am getting one more block (same as this block sweet.phtml) at the bottom of home page.. below the footer link. Can anyone tell me whats the problem.

推荐答案

您已将您的代码块标记为输出代码块.当在控制器动作中通过renderView()渲染视图时，您的块既是回显其子级的块的子级( content 是core/text_list块)，又是输出区块将以其自身的权利呈现.

You've marked your block as an output block. When the view is rendered via renderView() in the controller action, your block is both a child of a block which echoes its children (content is a core/text_list block), as well as being an output block which will be rendered in its own right.

删除output="toHtml"位，您将拥有所需的内容.顺便说一句，您可以/应该将此更改从自定义page.xml移动到布局中的local.xml文件中-它只需要位于<page_two_columns_left />布局更新句柄之内即可.

Remove the output="toHtml" bit and you will have what you need. By the way, you could / should move this change from a custom page.xml and into a local.xml file in your layout - it need only be inside a <page_two_columns_left /> layout update handle.
