validating a dropdown option (menu)

Working on a small website that contains a form, one of the options is a drop-down option(menu) that look like this

adduser.html

<label for="username">Username: <input type="text" id="username" name="username" value="" /><br /> 
<select name="level">
  <option value="1">Select Level...</option>
  <option value="2">Boss</option>
  <option value="3">Employee</option>
</select><br />
<label for="password">Password: <input type="text" id="password" name="password" value="" /><br />

And I'm doing this to validate if not option is selected

uservalidation.php

if(empty($_POST['username']))
{
  die("Enter a username<br><a href='adduser.php'>back</a>");
}

if(empty($_POST['password']))
{
  die("Enter a password<br><a href='adduser.php'>back</a>");
}

if(isset($_POST['level']) && ($_POST['level'] == '1'))
{
  die("Select level<br><a href='adduser.php'>back</a>");
}

But this is not working any idea why, or how to fix this?

Thanks in advance

Use form tags around the HTML and make sure you use method="post" in the form tag in order for your POST request to work in PHP.

The action attribute of the form tag just specifies the URL that the form will submit the data to.

Try this:

<form action="#" method="post">
<label for="username">Username: <input type="text" id="username" name="username" value="" /><br /> 
<select name="level">
  <option value="1">Select Level...</option>
  <option value="2">Boss</option>
  <option value="3">Employee</option>
</select><br />
<label for="password">Password: <input type="text" id="password" name="password" value="" /><br />
<input type="submit">
</form>
<?
if(isset($_POST['level']) && ($_POST['level'] == '1'))
{
  die("Select level<br><a href='adduser.php'>back</a>");
}
?>

UPDATE

As mentioned in the comments, I added an isset($_POST) check in there to avoid Undefined index.

It doesn't look like you're validating whether or not the form was posted.

if(isset($_POST['level']) && ($_POST['level'] == '1'))
{
  die("Select level<br><a href='adduser.php'>back</a>");
}
