The Game Rules :-
1- When the user first comes to the site a new expression is provided.
2- The user enters the guess and submits the form using the “Check” button.
3- The program checks the answer and if wrong provides a proper message and allows the user to keep guessing the same expression.
4- If the user guesses the result, then a new expression is provided. The Game problem I face it is :-
1- Never get true result.
2- The $expression not allows the user to keep guessing the same expression.
Note: I use random number between 1 and 12 inclusive function rand(1, 12)
<?php
$a= rand(1, 12);
$b= rand(1, 12);
$message;
$answer = null;
$expression = $a ." X ".$b ;
if (!isset($_POST['guess'])) {
$message = "Welcome to the Multiplication progarm<br/>";
}
elseif ($_POST['guess'] == $a*$b) { // matches!
$message = $a ." X ".$b." = ".$a*$b." is Correct!<br/> Now try the new expression";
$answer = $_POST['guess'];
}
elseif ($_POST['guess'] != $a*$b) { // some other condition
$message = $_POST['guess']." is Wrong!";
$answer = $_POST['guess'];
}
?>
<html>
<body>
<h2><?php echo $message; ?></h2>
<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="answer" value="<?php echo $answer;?>">
<input type="hidden" name="expression" value="<?php echo $expression;?>">
What is the value of the following multiplication expression:
<br>
<br>
<?php echo $expression; ?><input type="text" name="guess"><br>
<input type="submit" value="Check">
</form>
</body>
</html>
<?php
session_start();//you must use session in the first
$_SESSION['expression'] = $_POST['expression'];//define session to make the expression in the same value.
$_SESSION['answer'] = $_POST['answer'];//define session to make the answer in the same value.
elseif ($_POST['guess'] == $a*$b) { // matches!
$message = $a ." X ".$b." = ".$a*$b." is Correct!<br/> Now try the new expression";
session_destroy();//you must use this to stop session to produces new expression.
