Why is my XML not working?

Question

I'm trying to create a template file for a youtube video and some javascript. It should be added to the catalog/product/view/description block with the following PHP

 echo $this->getChildHtml('youtube')

This is the XML in my local.xml file that I'm using to try and get this to happen

<default>
    <catalog_product_view>
        <reference name="content">
            <reference name="product.info">
                <reference name="product.description">
                    <block type="core/template" name="product.youtube" as="product_youtube" template="catalog/product/view/youtube.phtml" />
                </reference>
            </reference>
        </reference>
    </catalog_product_view>
</default>

The template as of now just has a simple 'hello' but I don't get any output on my product page. What am I doing wrong?

Answer 1

local.xml should look like

<?xml version="1.0"?>
<layout version="0.1.0">
...

    <catalog_product_view>
        <reference name="content">
            <reference name="product.info">
                <reference name="product.description">
                    <block type="core/template" name="product.youtube" as="product_youtube" template="catalog/product/view/youtube.phtml" />
                </reference>
            </reference>
        </reference>
    </catalog_product_view>

...
</layout>

<default> and <catalog_product_view> are different handles.

So you should remove <default>

Also use $this->getChildHtml('product_youtube') to echo block

Answer 2

Small mistake echo $this->getChildHtml('youtube') should be echo $this->getChildHtml('product_youtube')

As your block alias name is product_youtube (as="product_youtube") and trying to call echo $this->getChildHtml('youtube')

Also as Anil mention

remove <default> and </default>
