Take my example :

<block type="core/template" name="my.name" as="myName" template="path/to/template.phtml"/>

What purpose does the "as=myName" declaration serve. What abstract class defines these default attributes for layout handling?

here i can give brief understanding regarding magento block xml tag

name = Name of the block. It should be unique in the page.

**as = Alias **. Smaller form of name. It should be unique in it's parent block.

template = The template file (View) this block is attached to.

You can call methods from block type inside this by using $this.. e.g. $this->getName()

name vs. as example:

<reference name="left">
    <block type="block/blocktype1" name="first_block" template="template1.phtml">
       <block type="abc/abc" name="ty1" as="common" template="abc.phtml"/> 
    </block>
    <block type="block/blocktype1" name="second_block" template="template2.phtml">
       <block type="xyz/xyz" name="ty2" as="common" template="xyz.phtml"/>            
    </block>
</reference>

So, you can now call block name ty1 from first_block AND ty2 from second_block as $this->getChildHtml('common');, but see both the blocks called will be different as per their calling parent.

for detail class go throw this

  • I understand all of that but you use the name if you want to do something like: is it purely an alias? a second name for easier recognition? – ajameswolf Sep 24 '13 at 14:57

When you use as, you can call $this->getChildHtml("as_value") on the phtml template.

The name must be unique, and can be used for < reference > blocks, < remove >, etc.

For example (catalog.xml):

<block type="catalog/product_view" name="product.info" template="catalog/product/view.phtml">
<block type="catalog/product_view_media" name="product.info.media" as="media" template="catalog/product/view/media.phtml"/>
