What does $_POST look
like when the following form is submitted with the third option in
the Braised Noodles menu
selected, the first and last options in the Sweet
menu selected, and 4 entered into the text box?
<form method="POST" action="order.php">
Braised Noodles with: <select name="noodle">
<option>shredded ginger and green onion</option>
Sweet: <select name="sweet[ ]" multiple>
<option value="puff"> Sesame Seed Puff
<option value="square"> Coconut Milk Gelatin Square
<option value="cake"> Brown Sugar Cake
<option value="ricemeat"> Sweet Rice and Meat
Sweet Quantity: <input type="text" name="sweet_q">
<input type="submit" name="submit" value="Order">
Write a process_form( ) function that prints out
all submitted form parameters and their values. You can assume that
form parameters have only scalar values.
Write a program that does basic arithmetic. Display a form with text
box inputs for two operands and a <select>
menu to choose an operation: addition, subtraction, multiplication,
or division. Validate the inputs to make sure that they are numeric
and appropriate for the chosen operation. The processing function
should display the operands, operator, and the result. For example,
if the operands are 4 and 2 and the operation is multiplication, the
processing function should display something like "4
* 2 = 8".
Write a program that displays, validates, and processes a form for
entering information about a package to be shipped. The form should
contain inputs for the from and to addresses for the package,
dimensions of the package, and weight of the package. The validation
should check (at least) that the package weighs no more than 150
pounds and that no dimension of the package is more than 36 inches.
You can assume that the addresses entered on the form are both U.S.
addresses, but you should check that a valid state and a ZIP Code
with valid syntax are entered. The processing function in your
program should print out the information about the package in an
organized, formatted report.
(Optional) Modify your process_form( ) function
from Exercise 6.2 so that it correctly handles submitted form
parameters that have array values. Remember, those array values could
themselves contain arrays.
