My code is simply to login.

understand why php capture only password )I call it senha) and take a blank

#Code - login.html

<form  method="POST" action="login.php">

#Code: login.php
<?

$sql = "SELECT * FROM usuario where nome='$nome' AND senha='$cod'"";
$tarefa=mysql_query($sql);
$num=mysql_numrows($tarefa);
$i=0;
if ($num < 1) {
header("Location:login.html");
} else {
while ($num > $i)  {
$nome = mysql_result($tarefa,$i,"nome");
$tipo = mysql_result($tarefa,$i,"tipo");
$i++;
}
setcookie("nome", "$nome");
setcookie("tipo", "$tipo");
header("Location:index.php");
}
?>
 

Are you shure that password is sent over also, because you will stil get 
an md5 hash on an empty string, meaning that even if $senha is empty you 
$cod wil produce a md5 hash.

Try fetching your username and password with the post array, that would 
be $_POST['nome'] and $_POST['senha'].
