selenium: WC()->cart and functions.php

jeudi 16 avril 2015

I get this error when adding this code to functions.php

Fatal error: Call to a member function calculate_totals() on a non-object

This is the code generating the error


WC()->cart->calculate_totals();
WC()->cart->calculate_shipping();
$packages = WC()->shipping->get_packages();

However when i put this code in header.php & footer.php no error and $packages array is returned.

How do i solve this, i need this code in functions.php?
