Problem sa updateom baze podataka u php-u

[ define @ 23.03.2005. 15:16 ] @

Ovako, nesto experimentisem i eto kao radio neku scriptu za ubacivanje linkova.
napravio sam stranicu gde mozete editovati neki post, medjutim javlja se greska kada ga pokrenem.
Ovako izgleda strana gde se ispisuju svi linkovi i do njih pise edit i delete
ako kliknem edit ono predje u stranicu za unosenje vrednosti i popuni vrednosti onog linka ciji je ID u ovom slucaju row

Code:

$conn=db_connect();
$sql="select * from linkovi order by id desc";
$result=mysql_query($sql);
print '<table>';
while($row=mysql_fetch_array($result)){
    print '<tr><td style="border:1px dotted silver">';
    print '[<a href="'.$row['adress'].'">'.$row['adress'].'</a>]';
    print '</td>';
    print '<td>';
    print $row['about'];
    print '</td><td>';
    print '[<a href="dellink.php?row='.$row['id'].'">brisi</a>]';
    print '</td><td>';
    print '[<a href="unesi.php?row='.$row['id'].'">edit</a>]';
    print '</td></tr>';
    }
echo '</table>';

kada editujem kako hocu kliknem na unos i ono prebaci na sledecu stranu

Code:

$adresa=addslashes($adresa);
$title=addslashes($title);
$about=addslashes($about);
$category=addslashes($category);
$conn=db_connect();
if(!$conn)
{
    echo 'Greskica';
}
if (isset($HTTP_POST_VARS['row']) && $HTTP_POST_VARS['row']!='')
{   // It's an update
  $row = $HTTP_POST_VARS['row'];

  $sql = "update linkovi
          set title = '$title',
              adress = '$adresa',
              about = '$about',
              category = '$category',
          where id = '$row'";
}
else {         // It's a new story
$sql="insert into linkovi (title, adress, about, category) values
('".$title."','".$adresa."','".$about."','".$category."')";
}
$result = mysql_query($sql, $conn);

if (!$result) {
  print "There was a database error when executing <pre>$sql</pre>";
  print mysql_error();
  exit;
}

Ukoliko vidi da je postojeci id onda samo updatuje taj unos, a ako vidi da ga nema onda upise novu.
E sada sve je to teoretski tacno medjutim javlja mi se ovo

Code:
There was a database error when executing
update linkovi
          set title = 'Auto Pijac',
              adress = 'http://www.autopijac.com',
              about = 'Auto Pijacasc',
              category = 'Politicki',
          where id = '20'
You have an error in your SQL syntax near 'where id = '20'' at line 6

U cemu je problem

Pa jesi li procitao poruku o gresci, jel znas kako glasi pravilna sintaksa UPDATE naredbe. Ovako odokativno moze biti da pre WHERE klauzule imas zarez koji tu nikakko ne bi trebao da se nalazi (... ='Politicki', WHERE id='20').
