In this tutorial we will be building a very simple login form using PHP and MySQL. Please note that this is very basic and I am not applying and security features to this tutorial. I will be covering a more advanced login system in future tutorials.
Source code is located on my website under the “Code Bank” section.

If password and username are correct how i can go to next page
Hi Tim, Love your tutorial, but your official website is NOT user friendly. I can NOT find the “CODE BANK” section anywhere ?
Is this way secure tho?
Hello Sir! I want to create an account for one person by using php. Could you do and post it? Thanks a lot!
Hello! It’s definitely a great tutorial! But I encountered a problem , can anyone help me?
The code I wrote seems to be perfectly fine, but for some reason it wouldn’t connect to db. The issue is that even if I use correct username and password it gives me “Invalid login information. Please return to the previous page.”
In the values of $host, $user, $pass and $db I’m 100% sure. Thanks in advance 🙂
< ?php $host = "localhost"; $user = "root"; $pass = ""; $db = "the allmighty one"; mysql_connect($host, $user, $pass); mysql_select_db($db); if (isset($_POST['username'])) { $username = $_POST['username']; $passwrod = $_POST['password']; $sql = "SELECT * FROM users WHERE username='".$username."' AND password='". $password."' LIMIT 1"; $res = mysql_query($sql); if (mysql_num_rows($res) == 1) { echo "You ahve successfully logged in."; exit(); } else { echo "Invalid login information. Please return to the previous page."; exit(); } } ?>
