How To Create A Login And User Profile Page Php

How To Articles

Creating a login and user profile page in PHP is an essential aspect of building a dynamic website. Not only does it allow users to access personalized content and features, but it also helps in keeping their data secure. In this article, I will guide you through the process of creating a login and user profile page using PHP, while adding personal touches and commentary from my own experience. So, let’s dive deep into the details and get started!

Setting up the Database

Before we dive into the code, we need to set up our database to store user information. In this example, let’s assume we have a database named “users” with a table named “users_table”. This table should have columns for user ID, username, password, email, and any other information you want to collect. Make sure to create the necessary columns and set appropriate data types and constraints to ensure data integrity and security.

Creating the Login Page

Now that we have our database set up, let’s create the login page. This page will contain a simple HTML form with fields for username and password. When the user submits the form, we will use PHP to validate their credentials against the data stored in the database.

Here’s an example of the HTML code for our login page:

<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">

In the above code, we have used the “action” attribute to specify the PHP file that will handle the login process (login.php in this case). The “method” attribute is set to “POST” to securely send the form data to the server. We have also added the “required” attribute to the username and password fields to ensure they are not left blank.

Now, let’s move on to the PHP code that will handle the login process. In the login.php file, we need to retrieve the form data, validate the credentials, and redirect the user to the user profile page if the credentials are correct.

  // Retrieve form data
  $username = $_POST['username'];
  $password = $_POST['password'];

  // Validate credentials
  // Add your code here

  // Redirect user if credentials are correct
  if ($valid_credentials) {
    header("Location: user_profile.php");
  } else {
    echo "Invalid credentials. Please try again.";

In the PHP code above, we retrieve the form data using the $_POST superglobal and store it in variables. The next step is to validate the credentials. This involves querying the database to check if the provided username and password match any records. You can use SQL queries and prepared statements to ensure the security of this process. Once the credentials are validated, we use the header() function to redirect the user to the user profile page.

Creating the User Profile Page

The user profile page is where users can view and update their personal information. It’s important to secure this page behind a login system to ensure that only authenticated users can access it. In this example, let’s assume we have a user_profile.php file that will display the user’s information once they have successfully logged in.

Here’s an example of the PHP code for our user_profile.php file:

  // Check if user is logged in
  if (!isset($_SESSION['username'])) {
    header("Location: login.php");

  // Retrieve user information from the database
  $username = $_SESSION['username'];
  // Add your code here to query the database

  // Display user information
  echo "Welcome, " . $username . "!";
  echo "<p>Here's your profile information:</p>";
  echo "<p>Name: " . $name . "</p>";
  echo "<p>Email: " . $email . "</p>";

In the above code, we first check if the user is logged in by checking if the “username” key is set in the $_SESSION superglobal. If not, we redirect them to the login page using the header() function. Once we have confirmed that the user is logged in, we retrieve their information from the database using SQL queries. Finally, we display the user’s information on the page.


Creating a login and user profile page in PHP requires a combination of HTML, PHP, and database interactions. By following the steps outlined in this article, you can create a secure and user-friendly login system for your website. Remember to always prioritize the security of user data by using proper validation techniques and encryption methods. Have fun coding and exploring the possibilities of user authentication and profile management!
