thanks alot.. .

have a nice day.

check whether you are using post or get in form tag..

If the form is not submitted then the POST values are not set yet, hence the notice. Try:

<?php
  echo "<h1>Register Now!</h1></br>";
  $submit = isset($_POST["submit"]) ? true : false;
 
  if ($submit)
  {
    $fullname = $_POST["fullname"];
    $username = $_POST["username"];
    $password = md5($_POST["password"]);
    $repeatpassword = md5($_POST["repeatpassword"]);

    echo "$username/$password/$repeatpassword/$fullname";
  }
?>

@Shanti_Chepuru

Heres my code.. .

<?php
echo "<h1>Register Now!</h1></br>";
$submit = $_POST["submit"];

$fullname = strip_tags ($_POST["fullname"]);
$username = strip_tags($_POST["username"]);
$password = strip_tags($_POST["password"]);
$repeatpassword = strip_tags($_POST["repeatpassword"]);
$date = date("Y-m-d");

if ($submit)
{
	//check for existence
	if ($fullname&&$username&&$password&&$repeatpassword)
	{
		$password = md5 ($password);
		$repeatpassword = md5 ($repeatpassword);
		if ($password==$repeatpassword)
		{
		
			//check lenght of username and fullname
			if(strlen ($username)>30||strlen($fullname)>30)
			{
				echo "Max limit for username/fullname are 30 characters only";
			}
		}
		else
		{
			if (strlen ($password)>30||strlen($password)<6)
			{
				echo "Password must be between 6 and 25 characters!";
			}
			else
			{
				//register user
				echo "success!";
			}
		}
		}
	}
	else
	{
		echo "Please fill in <b>all</b> fields!</br>";
	}
	


?>

im using POST.

can you help me here!

Thanks alot..

your code is perfectly fine...
As per priteas insert these lines:

$submit = isset($_POST["submit"]) ? true : false;
if ($submit)
{
// your code
}

or try to print this:

if($_SERVER['REQUEST_METHOD'] == "POST")
{
print_r($_POST);
}

try once and post the error what exactly you got.

$password = md5 ($password);
...
if (strlen ($password)>30||strlen($password)<6)

Your if statement will always fail, as md5 returns a 32 character string.
