Hi There
I have a client who uses the forms for members of their designated driver service to book a collection. As it is online he wants to prevent people from booking less than 5 hours in advance of pickup. This means that the form must not allow the user to select anything within 5 hours of the current time.
How do I go about adding this kind of functionality?
We don't have anything like this built into Gravity Forms. You would have to have a custom script written to hook into our hooks to make something like this happen. You would want to have a drop down field that is prerendered by a function grabbing the current time, and creating a list of options based on how many options you want to give users (15m intervals? 30m...?) and then fill the drop down field with the values using gform_pre_render.
OK, please let us know here if you need any more pointers.
