How To Make Login Page In Codeigniter

How To Articles

Today, I want to share with you my experience in creating a login page in CodeIgniter. As a developer, I know how important it is to have a secure and user-friendly login system. CodeIgniter is a powerful PHP framework that provides a solid foundation for building web applications, and its built-in features make it easy to create a login page from scratch.

Getting Started with CodeIgniter

The first step is to make sure you have CodeIgniter installed on your system. If you haven’t installed it yet, head over to the official CodeIgniter website ( and download the latest version.

Once you have CodeIgniter installed, create a new project directory and navigate to it using the command line. Run the following command to create a new CodeIgniter project:

composer create-project codeigniter4/appstarter

Creating the Login Controller and View

Now that we have our CodeIgniter project set up, let’s start by creating a new controller for our login page. In the app/Controllers directory, create a new file called Login.php. Here’s a simple example of what the controller might look like:

<?php namespace App\Controllers;

class Login extends BaseController {

public function index()
// Your code here


In the above code, we’ve created a basic controller called Login with an index() method. This method will be responsible for loading the login view.

Now, let’s create the view file for our login page. In the app/Views directory, create a new directory called login, and inside it, create a file called index.php. Here’s an example of what the view file might contain:

<h2>Welcome to the Login Page</h2>

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

In the view file above, we’ve created a simple HTML form with fields for the username and password. The form’s action attribute is set to /login/process, which will be the endpoint where we’ll handle the form submission.

Handling Form Submission

Now that we have our login controller and view set up, let’s handle the form submission. In the Login controller, add the following code to the index() method:

public function process()
$username = $this->request->getVar('username');
$password = $this->request->getVar('password');

// Your code here

In the above code, we’re using CodeIgniter’s request helper to retrieve the values of the username and password fields from the form submission.

At this point, you can add your own logic to authenticate the user and redirect them to the appropriate page based on their credentials. You can also add validation rules to ensure that the fields are not empty and meet your specific requirements.


Creating a login page in CodeIgniter is a straightforward process. By following the steps above, you can quickly set up a secure and user-friendly login system for your web application. Remember to always prioritize security and validation when handling user authentication.

Now that you have a basic understanding of how to create a login page in CodeIgniter, I encourage you to explore more advanced features and techniques to enhance the login experience for your users. Happy coding!
