I've built an application that allows users to select a phone and send it to
the rate plan page. Then, the rate plan page allows the user to select a
rate plan and pass both the phone and rate plan to an order page. In this
scenario, the user must first select a phone, and then select the rate plan
(in that exact order). However, I'd like to allow the user to select a rate
plan first (if they so choose) and then select the phone. In order to do
that, I thnink I need to check the phone field on the rate plan page to see
if its been populated. If the phone field is empty, I want to redirect the
user to the phone page instead of moving directly to the order page. Is
there a "How To" article that describes how to check a field to see whether
or not it's null and redirect the user accordingly?
Thank you!
