How can I modify fields?

[iTal]

Hi all,

I would like to know how I can post the hidden attributes of the "order now" buttons to change hidden fields like the price, the item description, and so on? We need to do that because we are setting the prices in our own internal database.

You would need to use a variable price product and set the various fields in your submit. Note that the product name, price and sku can be sent but the description, image can not.

Check the online documentation for variable price example code.
