As a web developer, one of the most common tasks is to create secure login systems for websites. In this article, I will guide you through the process of creating an HTML login page with a database to store user credentials.

Step 1: Designing the Login Form

The first step in creating an HTML login page is to design the login form. This form will contain input fields for the username and password, as well as a login button.

Here is an example of a basic login form:

<form action="login.php" method="POST"> <label for="username">Username:</label> <input type="text" id="username" name="username" required>


    <label for="password">Password:</label>

    <input type="password" id="password" name="password" required>

<input type="submit" value="Login"> </form>

Make sure to replace the form action attribute with the URL of the server-side script that will handle the login process. In this example, we assume that the login script is named “login.php”.

Step 2: Creating the Database

Now that we have our login form, we need a database to store the user credentials. For this, we will use a relational database management system like MySQL.

Let’s create a table called “users” with the following columns:

id: an auto-incrementing primary key
username: the username of the user
password: the password of the user (stored securely using hash functions)

Here is the SQL statement to create the table:

CREATE TABLE users ( id INT AUTO_INCREMENT PRIMARY KEY, username VARCHAR(255) NOT NULL, password VARCHAR(255) NOT NULL );

Remember to hash the passwords before storing them in the database to ensure security. You can use a library like bcrypt or Argon2 for this purpose.

Step 3: Handling the Login Process

Now that we have the login form and the database set up, we need to handle the login process. This involves verifying the user’s credentials against the data stored in the database.

Here is an example of how the server-side script (in our case, “login.php”) can handle the login process:

<?php // Retrieve the username and password from the login form $username = $_POST['username']; $password = $_POST['password'];


  // Hash the password for comparison with the stored password in the database

  $hashedPassword = password_hash($password, PASSWORD_DEFAULT);
  // Query the database to check if the user exists

  $query = "SELECT * FROM users WHERE username = '$username';"

  $result = mysqli_query($connection, $query);
  // Check if the query returned any rows

  if (mysqli_num_rows($result) == 1) {

    $row = mysqli_fetch_assoc($result);

    $storedPassword = $row['password'];

// Verify the password if (password_verify($password, $storedPassword)) { // Successful login echo "Login successful!"; } else { // Invalid password echo "Invalid password!"; } } else { // User not found echo "User not found!"; } ?>

Make sure to replace the database connection details and modify the code according to your specific server-side environment.

Conclusion

In this article, we explored the process of creating an HTML login page with a database to store user credentials. We learned how to design the login form, create the database table, and handle the login process using server-side scripting.

Remember, security should be a primary concern when implementing login systems. Always hash passwords before storing them in the database and use secure server-side scripting techniques to handle user authentication.

Now that you have a better understanding of creating an HTML login page with a database, you can apply this knowledge to build secure authentication systems for your web applications. Happy coding!
