how to update price from front end in ubercart product in drupal 7? I have a site in drupal 7, and I am the admin of site. I am using ubercart in my site for products. I have lot of products in my site with attributes and options. My products options are price based..

For example: I have one jewellery $100 with siver $23 and gold $43. Silver and gold are comming from option.

I want to update  options price from front end where product are displaying without going from edit product from backend.
This functionality isn't built into Ubercart. In order to do something like this, you're going to have to implement your own custom form to manipulate the options data, or, better yet, invoke uc_object_options_form (the options form display on node/$nid/edit/options) with drupal_get_form().
