Answer 1

you use twig function for OC2.3 version. This OC version does not suport twig. And instead user_token should be just token. Script you need change to:
<script type="text/javascript"><!--
function refudt(ele){
var pid = $(ele).data('pid');
var type= $(ele).data('type');
$.ajax({
url: 'index.php?route=sale/order/getprice&token=<?php echo $token; ?>,
dataType: 'html',
type: 'post',
data: 'order_id=<?php echo $order_id; ?>&pid=' + pid+'&type='+type,
success: function(html) {
$(ele).parent().append('<br>'+html);
}
});
}
function saver(ele){
var pid = $(ele).data('pid');
var price = $(ele).parent().find('input').val();
var type= $(ele).data('type');
confirm('Save new value: '+price +' ?');
$.ajax({
url: 'index.php?route=sale/order/getprice&token=<?php echo $token; ?>,
dataType: 'html',
type: 'post',
data: 'order_id=<?php echo $order_id; ?>&pid=' + pid+'&value='+price+'&type='+type,
success: function(html) {
$(ele).parent().remove();
if($('.rebus').length<1) {
location.reload();
}
}
});
}
//--></script>
Also do not forget that token should be defined on corresponding controller file like this: $data['token'] = $this->session->data['token'];
