Kā es varētu aizsragāt šo scriptu: links

Scripts domāts kā news publishing, viss strāda, bet vajag aizsargāt, to diemžēl es nemāku. Tapēc nāku prasīt palīdzību šeit :)

Paldies viss straada :*

<?
//connect to mysql
//change user and password to your mySQL name and password
mysql_connect("localhost","root","");

//select which database you want to edit
mysql_select_db("aaa");

//If cmd has not been initialized
if(!isset($cmd))
{
  //display all the news
  $result = mysql_query("select * from news order by id");

  //run the while loop that grabs all the news scripts
  while($r=mysql_fetch_array($result))
  {
  //grab the title and the ID of the news
  $title=$r["title"];//take out the title
  $id=$r["id"];//take out the id

 //make the title a link
  echo "<a href='delete.php?cmd=delete&id=$id'>$title - Delete</a>";
  echo "<br>";
}
}
?>

<?
if($_GET["cmd"]=="delete")
{
$sql = "DELETE FROM news WHERE id=$id";
$result = mysql_query($sql);
echo "Row deleted!";
}
?>
