Help cleaning up code

[Gonzo]

Thanks

Updated: movie_add.php
added: validation rules

Code:

<?php
include("database/database.php");
include("config/config.php");

// Set variables
$movie = mysql_real_escape_string($_POST['movie']);
$descr = mysql_real_escape_string($_POST['descr']);
$stock = mysql_real_escape_string($_POST['stock']);

// Insert set values
if ($movie == "" or $descr == "" or $stock == "") {
echo "INPUT ERROR";
} else {
mysql_query("INSERT INTO movies
(movie, description, stock) VALUES ('$movie', '$descr', '$stock') ")
or die(mysql_error());
echo "<b>" . $movie . "</b>" . " Added";
}
echo "<br />" . $___adminlink;
?>
