How to Make Simple Login Form in PHP with MySQL Database
Follow the following steps to create simple login form in PHP with MySQL database:
- Create a Database Connection File
- Create Login Page In PHP
- User Profile Page PHP File
1. Create a Database Connection File
In this step, we will create a file name db.php and update the below code into your file.
The below code is used to create a MySQL database connection in PHP. When we insert form data into MySQL database, there we will include this file:
<?php
$servername='localhost';
$username='root';
$password='';
$dbname = "my_db";
$conn=mysqli_connect($servername,$username,$password,"$dbname");
if(!$conn){
die('Could not Connect MySql Server:' .mysql_error());
}
?>
2. Create Login Page In PHP
In this step, we need to create a form, where we accept user email id and password. So you can create a login.php file and update the below code into your file.
The below code is used to show login form and authenticate the user with MySQL database in PHP.
<?php
session_start();
require_once "db.php";
if (isset($_SESSION['user_id']) != "") {
header("Location: dashboard.php");
}
if (isset($_POST['login'])) {
$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$email_error = "Please Enter Valid Email ID";
}
if (strlen($password) < 6) {
$password_error = "Password must be minimum of 6 characters";
}
$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email . "' and password = '" . md5($password) . "'");
if ($row = mysqli_fetch_array($result)) {
$_SESSION['user_id'] = $row['uid'];
$_SESSION['user_name'] = $row['name'];
$_SESSION['user_mobile'] = $row['mobile'];
$_SESSION['user_email'] = $row['email'];
header("Location: dashboard.php");
} else {
$error_message = "Incorrect Email or Password!!!";
}
}
?>

session_start();
if(isset($_SESSION['user_id']) =="") {
header("Location: login.php");
