在Magento中创建一个新块 [英] Create a new Block in Magento

问题描述

我昨天问了这个问题 Magento主页上的静态块，它回答了我关于将cms/块连接到现有块(在该示例中为内容).

I asked this question yesterday Static block on home page in Magento, which answered my question about hooking a cms/block to an existing block (content, in that example).

但是现在我想知道如何创建自己的块.

But now I would like to know how to create my own block.

我的.phtml模板中有此文件:

I have this in my .phtml template:

<?php echo $this->getChildHtml('home_flash') ?>

这在我的cms.xml文件中

And this in my cms.xml file

<reference name="home_flash">
  <block type="cms/block" name="home-page-flash" before="content">
    <action method="setBlockId"><block_id>home-page-flash</block_id></action>
  </block>
</reference>

但这不起作用.

我还试图在page.xml文件中创建自己的块类型(通过复制面包屑声明):

I have also tried to create my own block type, (by copying the breadcrumbs declaration) in the page.xml file:

<block type="page/html_home_block" name="home_block" as="home_block" template="page/template/home_block.phtml"/>

该文件存在，但未呈现.

That file exists but isn't being rendered.

但是当我引用这样的代码块时:

However when I reference the block like this:

<block type="page/html_breadcrumbs" name="home_block" as="home_block" template="page/template/home_block.phtml"/>

它呈现了我的home块模板，但是原始cms/block没有附加到它.

It renders my home block template, but the original cms/block is not attached to it.

希望所有不同的情况都能显示正在发生的事情，并充分突出我的知识差距，以便有人回答，我是否必须在某个地方注册"新的"home_block"类型?

Hope all the different cases show what is happening and highlight the gap in my knowledge well enough for someone to answer, do I have to "register" my new "home_block" type somewhere?

推荐答案

您可以使用许多不同的块而无需创建自己的块.在这种情况下，我认为core/text_list是合适的，因为它不需要模板，并且其中可以包含所需的任意数量的子块.

There are many different blocks available that you can use without creating your own. In this case I think core/text_list would be suitable because it doesn't require a template and can have as many child blocks within it as you need.

<?xml version="1.0"?>
<layout version="0.1.0"><!-- All layout files start with this -->
    <cms_index_index><!-- Index directive is the same as "home" page -->
        <reference name="root"><!-- For more blocks that can be referenced see "default" directive -->
            <block type="core/text_list" name="home_flash">
                <block type="cms/block" name="home-page-flash">
                    <action method="setBlockId"><block_id>home-page-flash</block_id></action>
                </block>
            </block>
        </reference>
    </cms_index_index>

    <!-- More directives might go here -->

</layout>

其他有用的块类型值得了解的是core/text和core/template，它们分别对应于Mage_Core_Block_Text和Mage_Core_Block_Template.他们最习惯了.
您自己制作的page/html_home_block块类型没有任何具有匹配名称的PHP类，如果您是真正创建自己的PHP类，则由于Magento已经使用了page前缀，因此无法使用.

Other useful block types worth knowing are core/text and core/template which correspond to Mage_Core_Block_Text and Mage_Core_Block_Template respectively. They get used the most.
Your home made block type of page/html_home_block didn't have any PHP class with a matching name, and if you were genuinely creating your own you wouldn't be able to use the page prefix since Magento already does.

要创建块，只需在布局文件中使用<block>标签.
要创建块类型，您需要编写一个PHP类，为其提供一个名称空间，并将其声明为模块的一部分.
添加到现有块的时间就是使用<reference>标记的时间.

To create a block you only need a <block> tag in the layout file.
To create a block type you need to write a PHP class, give it a namespace and declare it as part of a module.
To add to an existing block is the time when you use a <reference> tag.

Magento知识库上有很多精美的文章，其中包括

There are many fine articles at Magento Knowledge Base including some on Theming & Design.
