making a button and connecting to mysql

[system]

How would I go about making a button where if it gets clicked $value1 goes up by 1?

[system]

I’ve got the button working

[php]

Clicks: //The value i’m trying to increase

<?php
$username= $_SESSION['user']['username'];
$sql= "SELECT clicks FROM users where username='$username'";
$result = mysqli_query($conn, $sql);
$row = mysqli_fetch_assoc($result);
$_SESSION['clicks']= $row['clicks'];
echo $row['clicks'];
?><br><br>

<?php if(isset($_REQUEST['click'])) { echo "click"; }

?>

[/php]

This scares me… It looks AWFULLY like a label for a GOTO statement.
