How To Connect Login Page To Database In Phpmyadmin

PHP Programming

Connecting a login page to a database in PhpMyAdmin is an essential step in creating a secure and user-friendly web application. As a web developer, I have experienced the importance of this process first-hand, and in this article, I will guide you through the steps involved.

Step 1: Set up a Database

The first step is to set up a database in PhpMyAdmin. Log in to your PhpMyAdmin dashboard and create a new database by clicking on the “New” tab. Give your database a name that is relevant to your project, and click on the “Create” button.


Make sure to note down the name of your database, as you will need it later in your PHP code.

Step 2: Create a Table

Next, you need to create a table within your database to store the user information. Click on the name of your database in the left sidebar, and then click on the “Create Table” button. Define the structure of your table by specifying the column names and their data types.

username VARCHAR(30) NOT NULL,
password VARCHAR(30) NOT NULL

In this example, I have created a table named “users” with three columns: id, username, and password. The id column is set as the primary key, and both username and password columns are set as not null.

Step 3: Create a Login Form

Now it’s time to create the login form in HTML. This form will collect the user’s login credentials and send them to the server for verification. Below is an example of a simple login form:

<form method="post" action="login.php">
<input type="text" name="username" placeholder="Username" required>
<input type="password" name="password" placeholder="Password" required>
<input type="submit" value="Login">

Feel free to add additional styling and validation to the form based on your project’s requirements.

Step 4: Create a PHP Script for Login Verification

Now, let’s create a PHP script named “login.php” that will handle the login verification process. This script will receive the login credentials from the login form, query the database for a matching username and password, and redirect the user accordingly.

// Get the login credentials from the form
$username = $_POST['username'];
$password = $_POST['password'];

// Connect to the database
$conn = mysqli_connect('localhost', 'root', '', 'mydatabase');

// Query the database for a matching username and password
$query = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
$result = mysqli_query($conn, $query);

// Check if the query returned a row
if (mysqli_num_rows($result) == 1) {
// Redirect the user to the dashboard or homepage
header("Location: dashboard.php");
} else {
// Display an error message
echo "Invalid username or password.";

// Close the database connection

Make sure to replace ‘localhost’, ‘root’, ”, ‘mydatabase’ with your own database connection details.


Connecting a login page to a database in PhpMyAdmin is a crucial step in building a secure and functional web application. By following the steps outlined in this article, you can ensure that your users’ login information is securely stored and validated. Remember to always sanitize user input and use secure hashing algorithms to store passwords in the database. Happy coding!
