Add a field to the order

[littlesnack]

I need to add a html select to the cart page (before the comments) and let the user choose a value.
Then i would like to store the value in a database table (not related to virtuemart).
What i need to know is: which script/s save the value of customer_comment?

Thanks in advance

You need to create a custom plugin to achieve this. Then call it inside the <form> tag in components\com_virtuemart\views\cart\tmpl\default.php

Is there a guide for this? If not, where do i put the code to save the data in a database table?

Thanks again
