Why didn’t the POST request work?
It’s got to be the placeOrder.php script.
We told open() to use POST for the
request, so it’s got to be a server problem.
I already told you, there’s no problem
with my script. You must have screwed
something up in your JavaScript code.
Jim: Are you sure? I’ll bet you forgot to change your
script to accept POST parameters. Come on, just
admit it! Fix the thing, and we can get on with it...
Frank: Look, do you have a hearing problem? I’ve
told you twice now, my script accepts GET and POST
parameters. Are you sure you even sent the customer’s
order and address?
Jim: I’m positive. Once I realized how long someone’s
order could get, I updated the part of my JavaScript
that places the order to use a POST request.
Frank: Well, looks like you made a mistake.
Jim: No way. I put the customer’s phone number,
address, and order in the send() method of my
request object... I even double-checked. So I know the
data’s getting to the web server.
Frank: Well, it’s not getting to me. When my script
gets run by the server, and it checks for the “address”
and “order” request parameters, it’s not getting
anything.
Jim: Wait a second. If I’m sending the data to the
server correctly...
Frank: ...and I’m asking the server for the data, and
getting nothing...
Together: The problem must be the server!
This is Frank... he’s been
writing all the PHP scripts
for Break Neck ...
