PHP - Login Form With MySQL DataBase

How To Make Login Form In PHP With MySQL DataBase

In this PHP tutorial we will see how to create a login Page with a mysql database.

This page will contains a simple login form Using HTML, CSS and JavaScript.
the user enter his email and password and click on the login button,
and all we have to do is to check if a user with this email and password already exists on the database, and if the user don't exists show an error message, else redirect to the index page.

to do that we will ceate a class (db_connect) to connect our login form with mysql database, and After a successful login,redirect the user to the home page (index.php).

plus we will create a logout page system.

Project Source Code:

------------ Create A Class "db_connect" To Connect Our Form With Database

<?php

// Define database connection parameters

$servername = "localhost";

$username = "root";

$password = "";

$dbname = "login_db";

try

{

    // Create a new PDO instance

  $conn = new PDO("mysql: host=$servername;dbname=$dbname", $username, $password);

  // Set PDO error mode to exception

  $conn -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

}

catch(PDOException $e)

{

  // If a connection error occurs, display it

  echo"connection failed: " . $e->getMessage();

}

?> 

------------ On The Index Page ------------

<?php 

session_start();

$email = "";

$username = "";

if(isset($_SESSION['email']) && isset($_SESSION['username']))

{

    $email = $_SESSION['email'];

    $username = $_SESSION['username'];

}

else

{

  header("Location: login.php");

}

VB.Net Login Form With MySQL

VB.NET - How To Create Login From With  MySQL DataBase Using Visual Basic.Net

In This VB.Net Tutorial  We Will See How To Make A Login Window With MySQL Database 
In This Login Form We Will Add Two TextBox One For The Username And The Other For The Password, Add A CheckBox To Show And Hide Password Characters On CheckBox Checked Changed Event, Add Button Cancel To Close The Login Window,
Add Button Login To Search In MySQL DataBase If A User With This Username And Password Exists 
 - if the user exist hide this form and show a new form
 - if the user doesn't exist -> show a message
We Will Use MySqlCommand + MySqlDataAdapter + DataTable
Using Visual Basic.Net  Programming Language And Visual Studio Editor.
