CS 101   Web Construction,  Winter 2021 ,  Instructor:  Jeffrey Horn ASSIGNMENTS

• Assignment 5  "FORMS and Server-side Scripts"
  • Handed out:   Tuesday, March 9, 2021
    
  • Due:    Sunday, March 21, 2021, 11:59pm
    
  • Reading: 
    • Chapter 6 of the Jamsa textbook  (All of Ch.6!  It is short and all of the sections have good material. )
    • Note that there seems to be a problem with the textbook's server:  It won't run the two server-side scripts (FormEcho.php and FileUploader.php) that are offered in Ch. 6 as examples that can be used by us, the readers, to test our html forms.   The textbook's server, www.WebsiteDevelopmentBook.com, seems to be otherwise working, serving up .html files, but for some reason it won't run the php scripts.  Since Jamsa gives the code for these two scripts, I have typed them into files and put them on our Dept. server, where they seem to running just fine.   To use them, when trying out the exercises in Ch. 6 or testing your code for A5, put the following URLs into the action attribute for your <form> elements:
      • http://euclid.nmu.edu/~jeffhorn/cgi-bin/Jamsa/FormEcho.php  for the FormEcho script, and
      • http://euclid.nmu.edu/~jeffhorn/cgi-bin/Jamsa/FileUploader.php for the FileUploader script.
    • I strongly recommend you use FormEcho to test your code!   It is very helpful in seeing what is going on in this complex situation of multiple servers and files!
  • Goals:
    • Design and implement a web form, as an interface to an existing server-based script (program).
    • Learn to use several different versions of the <input> form element (i.e., text, submit, hidden, password, all of which are values for <input>'s "type" attribute).
    • Learn to be the interface between user and (script) programmer
  • Details:
    1. Create a web page (.html file) containing a <form> that allows the web user to play the "secret code" game. 
    2. The CS 101 A5 script is at http://euclid.nmu.edu/~jeffhorn/cgi-bin/A5.cgi  Have your form's action attribute point to this script, and use "POST" for the value of the method attribute.
    3. Your form should ask the user to guess the secret number (integer), 1-1000.
    4. To run the CS101 A5 script, your web page will need to send these named data fields to the server-side script:
       1. hiddenNumber:  A text string with a number in it.  This will be the users guess as to the "Mystery Number"!
       2. recipient:  A real email address (e.g., "jhorn@nmu.edu").   This should be hidden.
       3. fullname:  Your full name.
       4. firstname:  Your first name.
       5. lastname:  Your last name.
       6. nmuID:   Your NMU user name (e.g., mine is "jhorn").   This is NOT your NMU IN!
       7. URL:   This should be the actual, public web address for your A5 assignment (see below)
    5. Note that the names above are case-sensitive.
    6. Put your page on the web, but use a "cryptic" (i.e., non-obvious) URL, so as to discourage copying by other students!  (This is worth points!)
    7. When your form page is working, send me the URL by using your A5 form.  Include your best guess of the mystery number!   Instead of sending me an email directly, try to get the server-side script to send me an email with your URL for A5, and your name (in the body of the email message).
