    Hi Guys,

    I was wondering how to make this script work. I want it to add 1 to a variable every time the button is clicked. I already have,

    
<?php
session_start();

// if your variable is not yet defined, you assigned it with 0
if (isset($_SESSION['count']))
{
    $_SESSION['count'] = 0;
}

if($_POST['submit'])
{
    $_SESSION['count'] = $_SESSION['count'] + 1;
    echo $_SESSION['count'];
    ++$_SESSION['count'];  
}
?>
<!DOCTYPE html>
<html>
<head>
    <title>Bale Counter</title>
</head>
<body>
<form action="index.php" method="post">
    <input type="submit" name="submit" value="Bale Out">
</form>
</body>
</html>
    PHP:
    How do I make this work?

    Hi.
    Try the following modified code:
    <?php
session_start();

// if your variable is not yet defined, you assigned it with 0
if (!isset($_SESSION['count']))
{
    $_SESSION['count'] = 0;
}

if(isset($_POST['submit']))
{
    $_SESSION['count']++;
    echo $_SESSION['count'];
}
?>
<!DOCTYPE html>
<html>
<head>
    <title>Bale Counter</title>
</head>
<body>
<form action="index.php" method="post">
    <input type="submit" name="submit" value="Bale Out">
</form>
</body>
</html>

    Do you want to save that value for future reference as wel or just want that for a particular session?

    No, I want it to re-set when a reset button is pressed.

    I hope you know that session variable will expire within 30 to 180 mins depending on your PHP installation.

    You should replace your following code

    if (isset($_SESSION['count']))
    {
    $_SESSION['count'] = 0;
    }

    with

    if (!isset($_SESSION['count']))
    {
    $_SESSION['count'] = 0;
    }

    Save the variable's updated value in the database.
