I was working on a wordpress site with wp-e-commerce + goldcart and we wanted the “add to cart” button to also go to the cart whenever a product is added. Based on this thread here I was able to figure out what to do:
edit the file ‘wp-content/plugins/wp-e-commerce/wpsc-includes/display.functions.php’
on what is currently line 205, inside this part
<div class='wpsc-add-to-cart-button'>
<form class='wpsc-add-to-cart-button-form' id='product_<?php echo esc_attr( $product_id ) ?>' action=''...
changed:
action=”
to
action=’/products-page/checkout’
