How can I make the tryguess.php appear on the trynumber.php?


Recommended Posts




$_SESSION["correct_answer"] = rand(1,100);

$_SESSION["guess"] = 0;

    <h1>Welcome to the Great Number Game!</h1>

    <h2>I am thinking of a number between 1 and 100</h2>

    <h2>Take a guess!</h2>

    <form method="post" action="tryguess.php">

        <input type="text" id="guess" name="guess">

        <input type="submit" value="submit">

// header('Location: trynumber.php');

if (isset($_POST['guess'])) {

    if ($_POST['guess'] == $_SESSION['correct_answer']) {

        echo "correct!";


    if ($_POST['guess'] < $_SESSION['correct_answer']) {

        echo "too low";


    if ($_POST['guess'] > $_SESSION['correct_answer']) {

        echo "too high";

In the tryguess.php file, encase the code into a function.

On your trynumber.php script, include the tryguess.php script

Put the HTML in this trynumber.php script

change the form to POST to itself

run the function, included by tryguess.php, within the HTML to output the string you want.

Ok, save the guess result in a session, then if the session is not empty then display result

the problem you'll have is you randomise the number every time the form page is loaded.

Ideally one page is better for this project but you could do something like this:

Without writing the code i'll try to explain what i mean.


on a guess check if the guess is correct, save the result message to a session

   -- if the number is correct then also set the random number to nothing


if the random number is empty, then generate a new number,

if a result has been saved, then display it.


Hope that helps

All the seond script has to do is check the posted guess against the stored number and pass the result of that check back to the first script. Something like...


$resp = $_POST['guess'] <=> $_SESSION['correct_number'];

header("Location: trynumber.php?response=$resp");

the first page can then check if a response was returned and what the value is.

if $_GET['response'] == -1 then too low
else if $_GET['response'] == 1 then too high
else if $_GET['response'] == 0 correct
