I Need to address the following issue:
I have e-shop created in Ubercart. Some goods are fragile. I added to the content type "Product" hidden item boolean (fragile_field). This item is stored information if the goods are fragile or not.
Under the quota for the packages I have defined two ways to send:
1) normal package fragile
I need to create a rule (condition) which would prohibit the use of envelopes if your order is at least one item that is fragile.
In other words, if a customer will have a cart at least one item of the "fragile", the sending method "envelope" grayed and will remain inaccessible.
Do you know someone help me?
