Form error

[Bman900]

So I am following this tutorial on registering but it must have been coded in PHP4 because am getting different errors in PHP5. Here is what I have:

 

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

if(isset($_POST['submit'])) {

 

And here is the errors it throws up:

 

Notice: Undefined index: username in C:\wamp\www\mysite\register.php on line 32

Notice: Undefined index: password in C:\wamp\www\mysite\register.php on line 33

Notice: Undefined index: repeatpassword in C:\wamp\www\mysite\register.php on line 34

Notice: Undefined index: email in C:\wamp\www\mysite\register.php on line 35

 

This I understand because the first time you load the page there are no values in those variables but if I were to put that in my if statement I can not use those variables in my Form code as I want the information to stay within the form if an error message is thrown up. Here is the whole block of code that shows the form code as well and how I have it set up.

 

<?php 
$username = strip_tags($_POST['username']);
$password = strip_tags($_POST['password']);
$repeatpassword = strip_tags($_POST['repeatpassword']);
$email = strip_tags($_POST['email']);
$date = date("Y-m-d");

if(isset($_POST['submit'])) {



	//check if all fields are filled in
	if($username&&$password&&$repeatpassword&&$email) {
		//check if passwords match
		if ($password==$repeatpassword){
			//check character lenght
			if (strlen($username)>18 || strlen($username)<4){
			echo "User names must be within 4-18 characters. <a href=\"register.php\">Go Back</a>";
		}
		else {
		//check password lenght
		if(strlen($password)>15 || strlen($password)<6){
		echo "Password must be within 6 to 15 characters! <a href=\"register.php\">Go Back</a>";
		}
		//register user
		else {
		echo "Success!!";



		}
		}
		}	
		// error if passwords do not match
		else {

		echo "Your passwords do not match, please go back and try again! <a href=\"register.php\">Go Back</a>";

		}
	}
	//error if fields are not field in
	else {
	echo "Please fill in all field before proceeding! <a href=\"register.php\">Go Back</a>";

	}


}
?>
<form action='register.php' method="post"> 
<table>
	<tr>
		<td>
		Username:
		</td>
		<td>
		<input type='text' name='username' value =' <?php echo $username; ?>' />
		</td>
	</tr>
			<tr>
		<td>
		Password:
		</td>
		<td>
		<input type='password' name='password' />
		</td>
	</tr>
			<tr>
		<td>
		Repeat Password
		</td>
		<td>
		<input type='password' name='repeatpassword' />
		</td>
	</tr>
			<tr>
		<td>
		Email:
		</td>
		<td>
		<input type='text' name='email' value='<?php echo $email; ?>' />
		</td>
	</tr>
</table>
<p>
	<input type="submit" name="submit" value="Submit" />
</form>

Just move them inside the if( isset($_POST['submit']) ) { } conditional. There's no reason for them to be outside of it anyhow.

Yea I had to do that and I did if statements inside the value='' and worked like a charm!
