// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// get value of id that sent from address bar
$id=$_GET['id'];

// Retrieve data from database 
$sql="SELECT * FROM $tbl_name WHERE id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// update data in mysql database 
$sql="UPDATE $tbl_name SET targa='$targa', shteti='$shteti', pershkrimi='$pershkrimi' WHERE id='$id'";
$result=mysql_query($sql);

// if successfully updated. 
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='listo.php'>View result</a>";

Try this:

$sql="UPDATE $tbl_name SET targa='$targa', shteti='$shteti', pershkrimi='$pershkrimi' WHERE id='$id'";
echo $sql;
$result=mysql_query($sql);
if(mysql_affected_rows()){
    echo "Successful";
    echo "<BR>";
    echo "<a href='listo.php'>View result</a>";
}else {
    echo "ERROR";
}

But just so that you know, you haven't shown where variables like $targa ar set. Have they been taken from something like:

$targa = mysql_real_escape_string($_POST['targa']);

?

first i dont see where you grab the data from your post form for the update.

ex: $name = $_POST['name']; // and so on
or $sql="UPDATE $tbl_name SET targa='$_POST['targa']' ...

i personnally prefer to set local variables
im not even sure you can put a post data in a query, cause of the ' even with \' never done it.

and second how do you pass the variables to listo.php so it can echo it ?

anyways my 2 cents

maybe some guru have a better answer
