PHP website script problem

[w3rthlesspe0n]

So I'm working on a website for an airline (not real) and on one of my pages you can request the cost of a flight by putting in the depart and arrival locations, like this:

And if they put in a selection that isn't in the database they get this:

 

The problem is that when they load the page initially, instead of just the selection bars and sumbit button showing up, it all does and i get an error like this:

 

When you sumbit it, it all looks like it should, it's just that when they load it things seem to go wrong, any idea how i can fix this? 

 

Heres the code i use:

 <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
      <p>Depart:
        <select name="depart">
          <option selected="selected">Bristol</option>
          <option>Newcastle</option>
          <option>Manchester</option>
          <option>Dublin</option>
          <option>Glasgow</option>
        </select>
        Arrive:
        <select name="arrive">
          <option>Bristol</option>
          <option selected="selected">Newcastle</option>
          <option>Manchester</option>
          <option>Dublin</option>
          <option>Glasgow</option>
        </select>
<input type="submit" />
      </p>
    </form>
    <?php
$depart = $_POST['depart'];
$arrive = $_POST['arrive'];


$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("test", $con);

$result = mysql_query("SELECT price FROM flights WHERE depart = '$depart' AND arrive = '$arrive'");

if ($row = mysql_fetch_assoc($result)) {
echo 'This flight shall cost you &pound';
echo $row["price"];
}
else include('includes/price.php');
?>
</div> 

 

My if-else statement doesn't seem to be doing it's job 

 

Thanks in advance

Assuming that price.php gives you the blue table, you should add an if around the db stuff to only process when the form is submitted:

    <?php
if(isset($_POST['depart']))
{
$depart = $_POST['depart'];
$arrive = $_POST['arrive'];

        //... All db connection/query stuff

if ($row = mysql_fetch_assoc($result)) {
	echo 'This flight shall cost you &pound';
	echo $row["price"];
}
else include('includes/price.php');
}
?>
