TalkPHP - View Single Post - Creating a random number once and keeping it

bgs · 02-14-2012, 05:03 PM

Well, I've fixed it by using a hidden input and passing the value along via POST. Here's the working code:

Code:

<?php

	if (!isset($_POST["guess"]))
	{
		$message = "What number am I thinking of?";
		$num = rand(0,100);
	}
	else
	{
		$num = $_POST['num'];
		if ($_POST["guess"] > $num)
		{
			$message = "Too high, guess again!";
		}
		else if ($_POST["guess"] < $num)
		{
			$message = "Too low, guess again!";
		}
		else
		{
			$message = "Correct!";
		}
}
?>

<html>
<head><title>Number guess</title></head>
<body>
<?php echo $message ?>
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="POST">
<input type="text" name="guess"/>
<input type="hidden" name="num" value="<?php echo $num ?>" />
<p><input type="submit" value="Submit"/></p>
</form>
<?php echo $num ?>
</body>
</html>
