PHP Code:



<?php 

session_start(); 
if (isset($_SESSION['luckyNumber'])) { 

    $luckyNumber = $_SESSION['luckyNumber']; 

} else { 

    $luckyNumber = rand(1,100); 

    $_SESSION['luckyNumber'] = $luckyNumber; } 
if (isset($_POST['userNumber'])) { 

    if ($_POST['userNumber'] == $luckyNumber) { 

        $_SESSION['luckyNumber'] = rand(1,100);     } } ?> 
<html> <body> <center><h1>GUESS MY LUCKY NUMBER</h1> 

<?php 

$guessAttempt = (isset($_POST['guessAttempt'])) ? $_POST['guessAttempt'] + 1 : 0;
if (isset($_POST['userNumber'])) { 

    $userNumber = $_POST['userNumber']; 

    if ($luckyNumber > $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too small.</p>';     } else if ($luckyNumber < $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too high.</p>'; 

    } else { 

        echo '<p style="color:green;font-weight:bold">Well done! You got it right! .</p>' . $counter ;     } 

    } 
?> 
<p><strong>No of Guess attempt :</strong> <?php echo $guessAttempt; ?></p>

<form method="POST" action=""> 

Enter Number: <input name="userNumber" type="text"> 

<input type="hidden" name="guessAttempt" value="<?php echo $guessAttempt; ?>">

<button type="submit">Guess</button> 

</form> </center>

</body> 

</html>

How to do $guessAttempt using $_SESSION ?

http://php.flashwebhost.com/sibichan...er_session.php

I tried i like below and removed (<input type="hidden" name="guessAttempt" value="<?php echo $guessAttempt; ?>">) from <form> . Its not working.

PHP Code:



if(isset($_SESSION['guessAttempt'])){

$guessAttempt = $_SESSION['guessAttempt'];

}else {

    $guessAttempt = $_POST['guessAttempt'] + 1 ;}

HERE is the full code ($guessAttempt variable stored in $_SESSION).

No of Guess attempt showing as 1. The number is not increasing.

PHP Code:



<?php 

session_start(); 
if(isset($_SESSION['guessAttempt'])){

$guessAttempt = $_SESSION['guessAttempt'];

}else {

    $guessAttempt = $_POST['guessAttempt'] + 1 ;}
if (isset($_SESSION['luckyNumber'])) { 

    $luckyNumber = $_SESSION['luckyNumber']; 

} else { 

    $luckyNumber = rand(1,100); 

    $_SESSION['luckyNumber'] = $luckyNumber; 

} 
if (isset($_POST['userNumber'])) { 

    if ($_POST['userNumber'] == $luckyNumber) { 

        $_SESSION['luckyNumber'] = rand(1,100); 

    } 

} 

?> 

<html> <body> <center>

<h1>GUESS MY LUCKY NUMBER</h1> <?php if (isset($_POST['userNumber'])) { 

    $userNumber = $_POST['userNumber']; 

    if ($luckyNumber > $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too small.</p>'; 

    } else if ($luckyNumber < $userNumber) { 

        echo '<p style="color:blue;font-weight:bold">Try again. ' . $userNumber . ' is too high.</p>';
     } else { 

        echo '<p style="color:green;font-weight:bold">Well done! You got it right! .</p>' . $counter ;     } 

    } 

?> 
<p><strong>No of Guess attempt :</strong> <?php echo $guessAttempt; ?></p><form method="POST" action=""> Enter Number: <input name="userNumber" type="text"> <button type="submit">Guess</button> </form> </center>
</body> </html>

When you have an error or don't understand any part of the code, ask in the forum, Some one will be able to explain it different way or point out where the bug is. Don't get stuck with some thing, just ask. Everyone get stuck at some point, a good understanding team can help each other and find solution to problem much faster.

Updated first post with updated script that will display number of try required to get the correct answer. It is ok if you don't understand that part, just skip it.
