COP3832, Assignment 5

Due Wednesday 11/22 at the start of class

You are to write a script for me. Add a link to your server page to the script. Hand in a printout of the script, and upload the source of your script.

Do not use CGI.pm for this assignment.

You may use the parse-lib.pl file which contains a function named get_query. To access this, include the following statements in your scripts

require '/home/scsfac/downeyt/scripts/parse-lib.pl';
%query = get_query();

After these commands. %query will be the associative array of name/value pairs of any parameters sent to your script.

You will need to use the split function to separate the choices in a checkbox or a multiple selection list.

Write a script that will display a form containing the following. Choose a theme of your choice. All the input elements should relate to your theme.

• A text box
• A textarea
• A group of three radio buttons, all with the same name and different values.
• A group of four check boxes, all with the same name and different values.
• A selection list of several options, only one option may be selected
• A selection list of serveral options, many of the options may be selected.
• A submit button
• A reset button

When the form is submitted:

• Verify that the text box is not blank, that at least one of the check boxes has been selected, and that at least one of the options from the multiple selection list is chosen. If not, then redisplay the above form with a message indicating which fields are missing. Be sure that the user's previous choices do not have to be reentered by the user.
• If all the data is present, then
  • Display a new page with all the user's choices listed in a well-formatted text display. Do not display the data using form elements, just display them as plain text (a table would be nice).
  • Add a form to the page with three buttons:
    • Add. When pressed, append the user's data to a file of your choice, redisplay the current page. Add the data in a nice format so that it will be easy to interpret the file when it is displayed.
    • View. When pressed, display all the contents of the file at the bottom of the current page. Use a preformatted tag so that the contents of the file are displayed the way they are sotred. <PRE> and </PRE> are the tags for preformatted text. (Redisplay the current page with the file's contents at the bottom.)
    • Edit. When pressed, redisplay the original form. Be sure that the user's previous choices do not have to be reentered by the user.
    • You will need a hidden element to remember what the user's data is in order to redisplay it.
• Extra Credit: When a user has missing data, only redisplay the form elements that need to be filled in. Your script must still remember the elements that were filled in. Hidden fields????
