Here's my code and I am getting an error undefined variable, this code submits the information submitted by the user to a mysql database.

<?php
include("header.html");
include("nav.html");
include("sidebars.html");
?>
<?php
$errors=array();
if(isset($_POST['submitted'])){
	if(empty($_POST['fname'])){
		$errors[]="You forgot to enter first name";
	}
	   else{
		   $fn=$_POST['fname'];
	   }
	if(empty($_POST['lname'])){
		$errors[]="You forgot to enter last name";
	}
	   else{
		   $ln=$_POST['lname'];
	   }
	if(empty($_POST['email'])){
		$errors[]="You forgot to enter email";
	}
	  else{
		  $email=$_POST['email'];
	  }
if(!empty($_POST['pass1']))
{
	if(($_POST['pass1'])==($_POST['pass2']))
	{
		$pass=$_POST['pass1'];
	}
	   else
	   {
		   $errors[]="The two passwords do not match";
	   }
}
else
{
	$errors[]="You forgot to enter a password";
}
}
if(empty($errors)){
	require_once("connect.php");
	$q="INSERT INTO users VALUES ('$fn','$ln','$email',SHA1('$pass'),NOW())";
	$r=@mysqli_query($dbc,$q);
}
if($r){
	echo "You are now a registered user";
}
else{
	echo "You could not be registered beacuse";
	foreach($errors as $msg){
		echo $msg."<br>";
	}
}
?>

This will happen when you load the page the first time as the sql will run, even though you haven't sent the form. Place all the code (except form) inside the conditional:

if(isset($_POST['submitted'] && !empty($_POST['submitted']))){
...
//place sql etc here
}

BTW it's not a good idea to place form handling code on the same page as the form. autoresubmit happens on refresh/reload.

Instead of enclosing $fn in '', enclose it in "".
insert into ........ ("$fn","$ln",.......)
