how to add a new field in prestashop checkout page

[HARI DUDDELA]

Hello,

I'm struggling to pass an additional field value from checkout process to order, but have no luck. Maybe somebody can help me?

I've created input on checkout page, where the user enters a value. I need to write this value to new column in order, when the checkout is complete. I've extended ps_order table and order.php class, adding there our new field, but I have no idea how to pass the value from checkout template to order table.

 

Thanks in advance
