Modifying the Shipping Information During Checkout

 

Introduction.  Now we want to allow the user to not have to use the shipping address and name in their profile for each order.  This can be quite important since while the billing is almost surely going to be the same as what is in the profile for each order, the shipping information might well chaneg with every order.

So we need to do several things.

  • display the current shipping information within the shopper's profile in a form
  • allow the shopper to change this information
  • make sure to validate the inputs so that required information is present
  • once the shipping information is acceptable all of the shopper's inputs are written to the order_data table

We have developed this page so it is a sticky form to retain whatever the shopper has previously entered.  It also posts to itself so that error messages are at the top of the page in red.  This page should be called checkout_modify_shipping.php.  This page is quite long because it has the sticky form for the shipping information as well as the input validation.

In many respects this is just the capabilities to update the shipping so the code structure will be very similar to what we have done in other places when updating the profile.  We only need to focus on the shipping information and form.

A general code description follows.

  • if this is the first time the page is accessed then we need to fill in the form with entries from the profile via the current $_SESSION variables
  • if this form has been submitted we need to start assessing the validity of the entries
    • we create a blank error_message
    • we append new messages to this error_message that depend on whether certain things are left blank
    • if the error_message isn't blank
      • we display the error_message at the top of the sticky form to help the shopper fill in blank entries
    • if the error_message is blank this implies there were no entry errors and we can
      • coalesce this information into the $_SESSION variables
      • reacquire the other profile information from the $_SESSION variables
      • connect to the database adn insert the information into the order_data table
      • redirect the shopper to the next PHP page checkout_completed.php
  • finally we have the sticky form which posts to itself

This leads us to the last page of our website.
