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>

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>
