嗨那些人请不要那么苛刻我是新手编码而只需要一些帮助如果没关系，我正在尝试创建一个pHp注册表但我得到这个1错误。

Notice: Undefined variable: register in D:\xampp\htdocs\loginscript\register.php on line 14

我的代码中有：

请感谢任何帮助，谢谢！

用户请求查看我的代码。

<?php session_start();


 include ('header.php');

 ?> 


<?php
//Gets the form submitted data

if ( isset($_POST['register']) ) {}

if($register == 1 && !empty($_POST)) // Checks if the form is submitted or not

{

//retrieve all submitted data from the form

$username = $_POST['username'];
$username = strip_tags($username); //strip tags are used to take plain text only, in case the register-er inserts dangours scripts.
$username = str_replace(' ', '', $username); // to remove blank spaces

$password = $_POST['password'];
$password = strip_tags($password); 
$password = md5($password); // md5 is used to encrypt your password to make it more secure.

$full_name = $_POST['full_name'];
$full_name = strip_tags($full_name);

$location = $_POST['location'];
$location = strip_tags($location);

$gender = $_POST['gender'];


$sql="SELECT id FROM users WHERE username='$username'"; // checking username already exists
$qry=mysql_query($sql);
$num_rows = mysql_num_rows($qry); 


//alert if it already exists
if($num_rows > 0) 
{
echo '
<div class="alert">
  <button type="button" class="close" data-dismiss="alert">&times;</button>
  <strong>username already exists!</strong> please choose another username
</div>
';
}

else 
{
// if username doesn't exist insert new records to database
 $success = mysql_query("INSERT INTO users(username, password, fullname, location, gender) VALUES ('$username', '$password', '$full_name','$location','$gender')");


 //messages if the new record is inserted or not
if($success) { 
echo '
<div class="alert alert-success">
