here is the code
<?php

include 'rb/db.php';

if (isset($_SESSION['login'])) {
    header("Location : /im");
    exit();
}

$data = $_POST;

$login = $data['login'];
$pass = $data['password'];

if (isset($data['btn-log-in'])) {
$res = mysqli_query($link, "SELECT `login` FROM `users` WHERE `login` = '$login'");
$count = mysqli_num_rows($res);

$pas = mysqli_query($link, "SELECT * FROM `users` WHERE `login` = '$login'");

$pashash = mysqli_fetch_array($pas);
$id = $pashash['id'];

if( $count > 0 ) {
    if ($pashash['password'] == $pass) {
        $_SESSION['login']=$login;
        $_SESSION['id']=$id;
    }else{
        $error = '<p class="red">неправельный пароль</p>';
    }
} else {
    $error = '<p class="red">неправельный логин</p>';

 }
 }

Open php_errors on the server and look.
You can guess in telepath mode for a long time.
PS This is a reference govnokod.
Read about MVC at least.
