I’m new to PHP, and I’m working on a random number game. If the user guesses the right number, he gets a point. However, I am having trouble giving the point to the user. This is the code that I have for the game:

:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

        <title>result</title>
        <link href="style.css" rel="stylesheet" type="text/css" />
    </head>

    <body>
        <div id="main"></div>

        <div id="enterNumber">

            <?php
            $number_actual = rand(1, 20);
            $number_guess = $_REQUEST["inputnumber"];
            echo "You chose: " . $number_guess . "<br />";
            echo "The random number is: " . $number_actual . "<br />";
            if ($number_guess == $number_actual)
                echo "You guessed <b>Correctly!</b>";


            elseif ($number_guess < $number_actual)
            {
                echo "You are too <b>Low</b>!";
                echo "<br />";
                echo "<br />";
                echo "Try guessing again...";
                echo "<form>
                        <input type='text' name='inputnumber' />
                        <input type='submit' value='Guess' />
                    </form>";
            }
            elseif ($number_guess > $number_actual)
            {
                echo "You are too <b>High</b>!";
                echo "<br />";
                echo "<br />";
                echo "Try guessing again...";
                echo "<form>
                        <input type='text' name='inputnumber' />
                        <input type='submit' value='Guess' />
                    </form>";
            }
            ?>
        </div>

    </body>
</html>

This is the code that gives the user a point, but I am getting a problem adding them together!

$query = mysql_query("SELECT * FROM quiz WHERE username='$username'");

$insert = "UPDATE `users` SET `points` = (`points` + 1) WHERE `username` = '".$username."'";

mysql_query($insert); 


header('location: succes.php');
}
}
?>

When I tried to add them, I did it like this:

<?php

$number_actual = rand(1, 20);
$number_guess = $_REQUEST["inputnumber"];
echo "You chose: " . $number_guess . "<br />";
echo "The random number is: " . $number_actual . "<br />";
if ($number_guess == $number_actual)
    $query = mysql_query("SELECT * FROM quiz WHERE username='$username'");

$insert = "UPDATE `users` SET `points` = (`points` + 1) WHERE `username` = '" . $username . "'";

mysql_query($insert);


header('location: succes.php');
}

echo "You guessed <b>Correctly!</b>";


elseif ($number_guess<$number_actual)
{
echo "You are too <b>Low</b>!";
echo "<br />";
echo "<br />";
echo "Try guessing again...";
echo "<form>
            <input type='text' name='inputnumber' />
            <input type='submit' value='Guess' />
        </form>";
}
elseif ($number_guess>$number_actual)
{
    echo "You are too <b>High</b>!";
    echo "<br />";
    echo "<br />";
    echo "Try guessing again...";
    echo "<form>
            <input type='text' name='inputnumber' />
            <input type='submit' value='Guess' />
        </form>";
}
?>

    you placed the echo "You guessed <b>Correctly!</b>"; between the if and the elseif. Should be:

    <?php
                $number_actual = rand (1,20);
                $number_guess = $_REQUEST["inputnumber"];
                echo "You chose: " . $number_guess . "<br />";
                        echo "The random number is: " . $number_actual . "<br />";
                                if ($number_guess==$number_actual) { // you forgot this curly brace
                                   $query = mysql_query("SELECT * FROM quiz WHERE username='$username'");

    $insert = "UPDATE `users` SET `points` = (`points` + 1) WHERE `username` = '".$username."'";

     mysql_query($insert); 

    echo "You guessed <b>Correctly!</b>"; // this was placed inbetween the if and the elseif

    header('location: succes.php');
    }
