I am tring to store and display the number of requests
that a user has submitted via a hidden field. I've
created a form that does a some simple addtion.
Everything works, but I need some direction as to how
I can store each number the user puts in and to
display them.
Please see below:
<?php
if ( ! isset( $_POST['number1'] ['number2'] ) ) {
$message = "Welcome to the numbers game!";
}
$number1 = (int) $_POST['number1'];
$number2 = (int) $_POST['number2'];
$result = (int) $number1 + $number2;
$num_selections = (int) $POST['num_selections'];
$num_selections++; // this is my attempt at collecting
// and displaying the numbers
?>
