This thread is more that a year old, but I can partially help for people using v.1.5:
To display the cart on the bank wire summary page, I inserted a new hook following this method:
http://www.prestashop.com/forums/topic/173027-solved-how-to-create-a-new-hook-in-15-am-i-doing-it-wrong/page__st__20
(The tutorial says that you don't have to, but I had to manually add the hook to the database).
I then made a copy of blockcart.tpl (named it blockcart2.tpl).
Following this, I inserted the code below before the last } of blockcart.php
public function hookDisplayMyNewHook($params) {
if (Configuration::get('PS_CATALOG_MODE'))
return;
// @todo this variable seems not used
$this->smarty->assign('order_page', strpos($_SERVER['PHP_SELF'], 'order') !== false);
$this->assignContentVars($params);
return $this->display(__FILE__, 'blockcart2.tpl');
}
You can then modify blockcart2.tpl to suit your needs.
I haven't tried to display the other information (carrier, address, etc), but I don't see any reason why it wouldn't work using the same method.
Good luck!!
