Ok thanks for your reply. I don't know what can I change to "exclude" this "custom_data". I replaced the original admin-comments.php file but it's the same problem. Here is the code if that help :
`
case 'savecomment':
if (!isset($_POST['id'])) {
header("Location: " . FULLWEBPATH . "/" . ZENFOLDER . "/admin-comments.php");
exit();
}
$id = sanitize_numeric($_POST['id']);
$name = mysql_real_escape_string(sanitize($_POST['name'], 3));
$email = mysql_real_escape_string(sanitize($_POST['email'], 3));
$website = mysql_real_escape_string(sanitize($_POST['website'], 3));
$date = mysql_real_escape_string(sanitize($_POST['date'], 3));
$comment = mysql_real_escape_string(sanitize($_POST['comment'], 1));
$custom = zp_apply_filter('save_comment_custom_data', '');
if (!empty($custom)) {
$custom = ", [code]custom_data[/code]='".mysql_real_escape_string($custom)."'";
}
$sql = "UPDATE ".prefix('comments')." SET [code]name[/code] = '$name', [code]email[/code] = '$email', [code]website[/code] = '$website', [code]comment[/code] = '$comment'".$custom." WHERE id = $id";
query($sql);
header("Location: " . FULLWEBPATH . "/" . ZENFOLDER . "/admin-comments.php?sedit");
exit();
}
