This method works only if there is no required fields. But if I need to field a required field as an email, then this method does not work.
open /components/com_virtuemart/views/cart/view.html.php
replace this:
$pathway->addItem(vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU'));
$document->setTitle(vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU'));
$text = vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU');
$this->checkout_task = 'confirm';
on this:
$pathway->addItem(vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU'));
$document->setTitle(vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU'));
$text = vmText::_('COM_VIRTUEMART_ORDER_CONFIRM_MNU');
$this->checkout_task = 'confirm';
header("Location: /cart.html?task=updatecart&option=com_virtuemart&view=cart&confirm=1");
but cart.html may be different
