Homework 3
Due Friday, November 2, 2012 at 11pm.
Please build a web page, at /default/index/ (so the controller is called index in the default controller). The web page must display a form to enter data for shipping a product. The form should contain the following fields, with the following validations:
- Name of recipient. This can be any string (no special validation).
- Address line 1
- Address line 2.
- State. This must be a pull-down multiple choice offering ... the 50 states, but if you feel lazy, offering 5 states or more (including California of course) is fine.
- ZIP. This must be exactly 5 digits.
- Phone. You can check that it contains exactly 10 digits, but you should accept things like (123) 456-7890 or 123-456-7890 or 123 456 7890 or (123) 456 7890 etc etc (that is, just check that there is a total of 10 digits, and disregard whatever else there is).
- Weight. This is a strictly positive (zero not accepted) floating point.
- Width, Height, Length: these three are strictly positive floating point values.
If the form contains errors, you should re-display it with some indication of the errors.
If the form does not contain any error, you should redirect to another page /default/output/ , where you show:
Name
Address 1
Address 2
State, ZIP
Phone
Density (this means, weight / (width * height * length))
To transfer the information from /default/index/ to /default/output/ , you can use the session information as explained in the book. Precisely, in the index controller you can do, before redirecting to /default/output/:
session.addr_name = ...session.address1 = ...session.address2 = ......session.density = ...And then in the output controller you can use session.addr_name, session.address1, ..., session.density to retrieve those values.
