[SOLVED] can you explain this?

[CyberShot]

my code works. But when I remove this

 

if (!mysql_query($sql,$con))
  {
	 die('Error: ' . mysql_error());
  }

 

include('connection.php');
$pattern = '/[A-Za-z]+/';

if(isset($_POST['name']) && preg_match($pattern, $_POST['name']))
{
$name = $_POST['name'];
$sql="INSERT INTO mytable (names) VALUES ('$name')";
header("Location: http://localhost/php_sandbox/dbtest/index.php");
}
else
{
echo "You must only use letters a to z";

}

if (!mysql_query($sql,$con))
  {
	 die('Error: ' . mysql_error());
  }


mysql_close($con);

 

the code stops working. Why would it stop working?

Because your query isn't executed any more.
