Login and Signup form using PHP and MySQL with validation


Login, Signup and Logout now common for any web application. Because without login we can not track the data who uses our application.

In this example we will discuss how to create a login and signup form using PHP and MySQL database.

For any kind of web application login, signup is the most important thing for security reasons. If we do not have login features in our web application then any one can access our data and services.

Here in this login and signup form example we using 5 files these are:

SQL file:
For create table

database.php:For connecting database

register.php:
For getting the values from the user

register_a.php:
A PHP file that process the signup request

login.php :for getting the values from the user

loginProcess.php :
For login process to check valid user or not

home.php :
for welcome page after login

logout.php :For logout from the application

Step 1:Create the above table

Step 2:
create all other files mentioned above.

Step 3:
Create an upload folder for storing the image file.

Then open your browser and put url localhost/login/

Sql file

CREATE TABLE `register` (   `ID` int(10) NOT NULL,   `First_Name` varchar(100) NOT NULL,   `Last_Name` varchar(100) NOT NULL,   `Email` varchar(100) NOT NULL,   `Password` int(100) NOT NULL,   `File` varchar(100) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
            

database.php

<?php     $url='localhost';     $username='root';     $password='';     $conn=mysqli_connect($url,$username,$password,"fregister");     if(!$conn){         die('Could not Connect My Sql:' .mysql_error());     } ?>
