Can I dynamically change Layouts?

Question

On the view.phtml is it possible to write php to change the layout depending on what item is displayed on that page?

Using code similar to this:

$this->loadLayout()
                   ->getLayout()
                   ->getBlock('root')
                   ->setTemplate('page/1column.phtml');      
$this->renderLayout();

Answer 1

No.

Templates belong to blocks, blocks belong to layouts and are loaded and generated by them. Therefore you can't change the layout from inside itself.

You can/should only change layout templates from a controller.

Answer 2

You can do this at product level from admin.

1. Create a custom view.phtml in template/catalog/product/my_view.phtml
2. Navigate in the admin to Product->Design->Custom Layout Update

Add this block:

<reference name="product.info">
    <action method="setTemplate"><template>catalog/product/my_view.phtml</template></action>
</reference>
