Encrypt:

$pwd = password_hash($this->request->getPost('pwd'), PASSWORD_BCRYPT);

Match:

$user = $this->db->table('customer')
                         ->select('id, first_name, last_name, uname, emailid, contact, picture, pwd')  // Email aur password select karo
                         ->where('emailid', $email)
                         ->get()
                         ->getRow();
                         
                    
                    if ($user && password_verify($password, $user->pwd)) {
                        
                        $record = $user;
                        // Password matches, login successful
                        $this->session->set('customerSessData', $record);

1. Configure Encryption in CI4

Ensure that the encryption service is properly set up. Open the app/Config/Encryption.php file and configure it:

<?php

namespace Config;

use CodeIgniter\Config\BaseConfig;

class Encryption extends BaseConfig
{
    public $key = 'your-encryption-key'; // Replace with a random key
    public $driver = 'OpenSSL';         // Use OpenSSL for encryption
}

Replace your-encryption-key with a strong random key. You can generate one using bin2hex(random_bytes(32)) in PHP.

2. Encrypt the Value

Use CI4’s encrypter() helper to encrypt the value before adding it to the URL:

use CodeIgniter\Encryption\Encryption;

$encrypter = \Config\Services::encrypter();

// The value to encrypt
$data = 'your-value-to-encrypt';

// Encrypt the value
$encryptedValue = base64_encode($encrypter->encrypt($data));

// Pass the encrypted value in the URL
$url = base_url('your-controller/your-method/' . $encryptedValue);

3. Decrypt the Value

Retrieve and decrypt the value in your controller:

public function yourMethod($encryptedValue)
{
    $encrypter = \Config\Services::encrypter();

    // Decode and decrypt the value
    try {
        $decryptedValue = $encrypter->decrypt(base64_decode($encryptedValue));
        echo 'Decrypted Value: ' . $decryptedValue;
    } catch (\Exception $e) {
        // Handle errors (e.g., invalid encryption or tampered data)
        echo 'Decryption failed: ' . $e->getMessage();
    }
}

4. Example Flow

• Encrypt and Generate URL:

  $data = '12345';
  $encryptedValue = base64_encode($encrypter->encrypt($data));
  echo base_url('example/decrypt/' . $encryptedValue);

  
  Decrypt in Controller:

  public function decrypt($encryptedValue)
  {
      $encrypter = \Config\Services::encrypter();
      $decryptedValue = $encrypter->decrypt(base64_decode($encryptedValue));
      echo 'Decrypted Value: ' . $decryptedValue;
  }

1. Created a Helper Function
Created helper functions for password hashing and verification to reuse across your application.

Create a file in app/Helpers, e.g., app/Helpers/password_helper.php

password_helper.php

<?php
    if (!function_exists('hash_password')) {
        function hash_password($password) {
            return password_hash($password, PASSWORD_BCRYPT);
        }
    }
    
    if (!function_exists('verify_password')) {
        function verify_password($input_password, $stored_hash) {
            return password_verify($input_password, $stored_hash);
        }
    }
?>

2. Hash Password During Registration

$password = $this->request->getPost('password');
$hashed_password = hash_password($password);

3. Verify Password During Login

$password = $this->request->getPost('password');
verify_password($input_password, $user->password);

If the password is verified, it will return 1, else blank. e.g. below

if(verify_password($password, $user->password)) {
	// Set session or other login logic
	session()->set(['username' => $user->username]);
	return redirect()->to('/superadmin/dashboard')->with('success', 'Login successful!');
}else {
	return redirect()->back()->with('error', 'Invalid credentials!');
}

1. Disable the button when the form is submitted.
2. Re-enable the button after the page is loaded or when the form submission is complete.

Example Implementation:

HTML:

<form id="myForm" method="POST" action="your-action-url">
    <!-- Your form fields here -->
    <input type="submit" value="Submit" class="btn btn-lg btn-success" id="submitButton">
</form>

JavaScript/jQuery:

$(document).ready(function() {
    // Disable the submit button when the page starts loading or the form is being submitted
    $('#myForm').submit(function(event) {
        // Disable the submit button
        $('#submitButton').prop('disabled', true);
        
        // Optionally, change the button text to indicate submission
        $('#submitButton').val('Submitting...');
        
        // If you're submitting via Ajax, handle it like this:
        // $.ajax({
        //     url: 'your-action-url',
        //     type: 'POST',
        //     data: $(this).serialize(),
        //     beforeSend: function() {
        //         // Disable the button before sending the request
        //         $('#submitButton').prop('disabled', true);
        //     },
        //     success: function(response) {
        //         // Handle successful form submission here
        //         // Re-enable the button if needed (or perform actions based on success)
        //         // $('#submitButton').prop('disabled', false);
        //         // $('#submitButton').val('Submit');
        //     },
        //     error: function() {
        //         // Handle error response
        //         // Re-enable the button in case of an error
        //         // $('#submitButton').prop('disabled', false);
        //         // $('#submitButton').val('Submit');
        //     }
        // });
        
        // For traditional form submission, we can rely on the browser's default behavior
    });
    
    // Disable button if the page is being loaded
    $(window).on('beforeunload', function() {
        $('#submitButton').prop('disabled', true);
    });
});

Explanation:

1. Disabling the Submit Button on Form Submission:
   • When the form is submitted ($('#myForm').submit()), we disable the submit button immediately ($('#submitButton').prop('disabled', true);) to prevent further clicks.
2. Changing the Button Text:
   • Optionally, you can change the button text to “Submitting…” or something else to give feedback to the user that the form is being processed.
3. Re-enabling the Button After Submission (Using Ajax):
   • If you’re using Ajax, you can re-enable the button when the submission is successful or if there’s an error by placing the code $('#submitButton').prop('disabled', false); in the success/error callbacks.
4. Disabling the Button on Page Reload or Unload:
   • $(window).on('beforeunload', function() {...}): This disables the button if the page is being unloaded, which could happen when the user reloads or navigates away while the form is submitting. This will prevent the form from being accidentally submitted multiple times due to a page reload.

Additional Notes:

• For Ajax Submissions: You can use the beforeSend function in the Ajax request to disable the button before sending the request, and re-enable it on the success or error response.
• For Traditional Form Submissions: The button will be disabled immediately on form submission, and the page reloads automatically once the form is submitted. After the page reloads, the button will be active again (if you set it to be enabled on page load).

Step 1: Create a Custom Router

Create a custom router that converts dashes to underscores in controller methods.

File Path: app/Controllers/Router.php

namespace App\Controllers;

use CodeIgniter\Router\RouteCollection;

class Router
{
    public static function convertDashToUnderscore(RouteCollection $routes)
    {
        $routes->setAutoRoute(false); // Disable default auto-routing for security.

        // Add a custom handler for dashes in method names.
        $routes->setTranslateURIDashes(true);
    }
}

Step 2: Modify Routes.php

In app/Config/Routes.php, include the Router::convertDashToUnderscore method to enable the mapping.

Update Your Routes.php

use App\Controllers\Router;

// Convert dashes to underscores in URLs automatically.
Router::convertDashToUnderscore($routes);

// Example route
$routes->match(['get', 'post'], 'admin/configurator/configurator/(:any)', 'admin\configurator\Configurator::$1');

Step 3: Test the URL

Now, accessing http://yourdomain.com/admin/configurator/configurator/order-partial-payment will automatically call the order_partial_payment method in your controller.

Notes:

1. Security Implications:
   • Be cautious when enabling auto-routing ($routes->setAutoRoute(true)), as it allows users to call any public method in your controllers.
   • It’s recommended to explicitly define routes to prevent unintended access.
2. Debugging:
   • Check routes using php spark routes to verify if your route is being mapped correctly.

To pass data (like success or error messages) during a redirect, you can use session flashdata.

Example:

Set flashdata in the controller before redirecting:

session()->setFlashdata('success', 'Operation completed successfully.');
return redirect()->to('/dashboard');

Retrieve flashdata in the redirected page:

if (session()->getFlashdata('success')) {
    echo session()->getFlashdata('success');
}

Redirect with POST/GET Data

To pass query parameters or data, append them to the redirect URL.

return redirect()->to('/search')->withInput(['query' => 'CodeIgniter']);

Retrieve input in the redirected controller:

$query = $this->request->getVar('query');

Conditional Redirect

You can dynamically redirect users based on conditions.

if ($user->isAdmin) {
    return redirect()->to('/admin/dashboard');
} else {
    return redirect()->to('/user/dashboard');
}

Use redirect() Helper Function

The redirect() function is a global helper and can be used without $this or BaseController.

Example:

return redirect()->to('/home');
