Magento – Move breadcrumb Block purely via local.xml

layout

I want to move the breadcrumb block purely using local.xml.

It needs to be moved from its default location to the content block somewhere for me to output.

Usually when moving blocks i would unsetChild and then insert, however, this is making the breadcrumb block appear twice and also its not actually moving it anywhere.

<reference name="root">
    <action method="unsetChild"><name>breadcrumbs</name></action>
    <reference name="content">
        <action method="insert"><child>breadcrumbs</child></action>
    </reference>
</reference>

This is a good exercise - a good chance to learn. Because a layout XML move in Magento 1 is really a composite operation (unser from original parent, add to new parent), debugging requires testing both conditions.

The insert is obviously working, as you are seeing the breadcrumbs block twice. That means that the unsetChild call is not working. This is almost always the result of one of two things: incorrect child alias or incorrect parent reference. In your case, it is the latter. This is the result of a custom (non-CE) theme; for example, the enterprise/default theme declares the breadcrumbs block in a core/text_list block named breadcrumbs.container.

Also, reference tags should not be nested. They will work when nested, but given that they operate against the global block list by name, it's not necessary.

And you won't be able to remove it without overriding something. Here is how the getToolbarBlock() method looks like:

public function getToolbarBlock()
{
    if ($blockName = $this->getToolbarBlockName()) {
        if ($block = $this->getLayout()->getBlock($blockName)) {
            return $block;
        }
    }
    $block = $this->getLayout()->createBlock($this->_defaultToolbarBlock, microtime());
    return $block;
}

This means that if a block with a certain name (value returned bygetToolbarBlockName) exists in the layout then that block will be returned. otherwise a new block is created with type catalog/product_list_toolbar and that is returned by the method.

[EDIT] I just had a crazy idea. Why not change the toolbar block type? That way it won't be rendered as a toolbar. I haven't tried it but I think it's worth it.
Something like:

<reference name="product_list">
    <block type="core/template" name="product_list_toolbar" />
</reference>

I mean adding a block with the same name but a different type. If it doesn't work please don't donwvote; it is just in idea :)

Magento – How to Add Block to product.info on in local.xml

The solution was to change the function name being called from addLink to something else. Even though overriding addLink works fine in catalog.xml, it does not work in local.xml. Can anyone offer insight as to why that's the case?
