There's something wrong with your query:

if (mysql_num_rows($login))

Another words, if you look closely here: $login which is line 7:

$login = mysql_query("SELECT * FROM admin WHERE (name = '" . mysql_real_escape_string($_POST['name']) . "') and (password = '" . mysql_real_escape_string($_POST['password']) . "')");

You query is wrong and you need to fixed in order it to work!

It's the query on line 7,
set variables first:

$name=$_POST['name'];
$name= mysql_real_escape_string($name);
$pass= $_POST['password'];

etc, and then the query:

mysql_query("SELECT * FROM admin WHERE name='$name' AND password='$pass'");

and do the same for the next query, re-using the same vars.
And you really should be hashing the password for security at least md5 or sha1
