thanks you guys for your suggestions!
my problem is not the weight selection, but the fact that the weight will not never be right…
my client wants the site working as a real vegetable shop.
for example:
i want to buy a watermelon of 1 kg, but it’s almost impossible that i’ll receive a watermelon of that weight – maybe 1,5kg or 0,9kg etc… – so i need to tell the client that the price of his order may change depending on the real weight of that watermelon.
the right method could be the same one used by hotels that block an amount of money from the credit card during the reservation…but i still don’t find some plugin doing this.
anyway i know that this way to manage the orders it’s a little bit intricate and probably there are not plugins doing this, so if some of you guys is able to do something like this we can talk in private for a quotation.
regards.
