How do I” Pass variable between .phtml files?

Question

I have a variable in item.phtml file (order approval extension) in my base folder and I want to pass It to another .phtml file (one called cart.phtml). I don’t think cart.phtml is a child of item.phtml. The variable is called $postdata and is just a simple PHP variable and I wish to display the text is holds on the same page as item.phtml but in another file.

Answer 1

I dont know why you want to do this But you can use Magento registry for this.

Set data to registry

Mage::register('name-of-registry-key', $postdata); 

Get your data

$var = Mage::registry('name-of-registry-key'); 

Clear registry data

Mage::unregister('name-of-registry-key');
