Check signup checkbox is check or not on checkout

Question

Hello currently i am using one page checkout and i want to know that signup check-box is check or not on checkout page. How can i know that sign up is checked or not?

Answer 1

You can check the value of

Mage::getSingleton('checkout/session')->getQuote()->getCheckoutMethod()

This value can be:

• empty - if the customer is already logged in
• register - if the customer chose to register
• quest - if the customer selected 'Checkout as guest'

[EDIT]
To know if a customer is logged in check this:

Mage::getSingleton('customer/session')->isLoggedIn();//true if the customer is logged in
