You should start trying to use transactions, that way if there was an error, any changes that successfully went through are also rolled back.

<?php
$debug = true;
//variable to commit transaction
$commit = "commit";
$errors = array();

/* fetch data from form input */

extract ($_POST);

/* connect to server */

if(!$db = mysql_connect("localhost", "root", ""))
{
	$errors[] = mysql_error();
}

/* select database */

if(!mysql_select_db("webauth", $db))
{
	$errors[] = mysql_error();
}

//begin transaction
if(!mysql_query("begin"))
{
	$errors[] = mysql_error();
}

/* fields' names in the database */
$result = "INSERT INTO buy (id,type,price,desc,email,apartment,roomno,qty)";

/* variable name as declared as above to be entered to the field */
$result .= "VALUES ('$id', '$type', '$price','$desc','$email','$apartment','$roomno','$qty')";

if(!mysql_query($result, $db))
{
	$commit = "rollback";
	$errors[] = mysql_error();
}


//$commit = "rollback";  //uncomment to automatically rollback the transaction

if($commit == "commit")
{
	mysql_query($commit);
	echo "successful";
	echo "<br>";
	echo "<a href=order.php>Home</a>";
	mysql_close($db);
}
else
{
	echo "there was an error in your transaction, transction rolled back: ";
	if($debug == true)
	{
		foreach($errors as $value)
		{
			echo "<p>" . $value . "</p>";
		}
	}
	mysql_query($commit);
	mysql_close($db);
}
/* variable name as declared as above to be entered to the field */
/* fields' names in the database */
/* execute the query */


?>
