Hello! I have little problem with my code.. and my head blow up... Code is php <?php include 'db.php'; if( isset($_POST['oak']) ){ $alltree = $_POST['alltree']; $oak= $_POST['oak']; $sql = "UPDATE users SET $puud = $puud + 1, $sirel=$sirel+1"; } if (mysqli_query($sql)) { echo "'+1 Oak tree added!"; } ?> <form action="demo.php" method="post"> <input type="submit" name="oak" value="Cut a tree!"> </form> My vision is.. if press CUT A TREE! and page updated.. and update my oak amount at mysql data.. So, i'm newbie but i take a little journey for study :)
