Stripe is a secure payment method and it’s work-based using API. it provides two environments for the user like a sandbox(Test) and live.

Overview

Step 1: Install or Download stripe-PHP Library
Step 2: Get and Set Stripe API Key and SECRET
Step 3: Create Controller
Step 4: Create View File

Step 1: Install or Download stripe-PHP Library
Now, we are going to install the stripe package using the below command and if you want to download the stripe-PHP library then you can download it on https://github.com/stripe/stripe-php. git repository.

composer require stripe/stripe-php

1	composer require stripe/stripe-php

Step 2: Get and Set Stripe API Key and SECRET
In this step, we have to need the API Key and SECRET Key. so we will go to the official Stripe site and after then login gets API Key and SECRET Key after then we will set in a config file.
application/config/config.php

$config['stripe_key'] = 'pk_test_xxxxxxxxxxxxxxxxxxx';
$config['stripe_secret'] = 'sk_test_xxxxxxxxxxxxxx';

1 2	$config['stripe_key'] = 'pk_test_xxxxxxxxxxxxxxxxxxx'; $config['stripe_secret'] = 'sk_test_xxxxxxxxxxxxxx';

Step 3: Create Controller

In this step, we will create a Stripe.php file in the “application/controller” directory and paste the below code in this controller.
application/controller/Stripe.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
    
class Stripe extends CI_Controller {
     
    /**
     * Get All Data from this method.
     *
     * @return Response
    */
    public function __construct() {
       parent::__construct();
       $this->load->library("session");
       $this->load->helper('url');
    }
     
    /**
     * Get All Data from this method.
     *
     * @return Response
    */
    public function index()
    {
        $this->load->view('stripe_form');
    }
        
    /**
     * Get All Data from this method.
     *
     * @return Response
    */
    public function payment()
    {
      require_once('application/libraries/stripe-php/init.php');
     
      $stripeSecret = 'YOUR STRIPE SECRETE KEY';
 
      \Stripe\Stripe::setApiKey($stripeSecret);
      
        $stripe = \Stripe\Charge::create ([
                "amount" => $this->input->post('amount'),
                "currency" => "usd",
                "source" => $this->input->post('tokenId'),
                "description" => "product 1"
        ]);
                   
        $data = array('success' => true, 'data'=> $stripe);
 
        echo json_encode($data);
    }
}
?>

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

class Stripe extends CI_Controller {

/**

* Get All Data from this method.

* @return Response

public function __construct() {

parent::__construct();

$this->load->library("session");

$this->load->helper('url');

}

/**

* Get All Data from this method.

* @return Response

public function index()

{

$this->load->view('stripe_form');

}

/**

* Get All Data from this method.

* @return Response

public function payment()

{

require_once('application/libraries/stripe-php/init.php');

$stripeSecret = 'YOUR STRIPE SECRETE KEY';

\Stripe\Stripe::setApiKey($stripeSecret);

$stripe = \Stripe\Charge::create ([

"amount" => $this->input->post('amount'),

"currency" => "usd",

"source" => $this->input->post('tokenId'),

"description" => "product 1"

]);

$data = array('success' => true, 'data'=> $stripe);

echo json_encode($data);

}

Step 4: Create View File

So finally, we will create the stripe_form.php file in the “application/views/” directory.
application/views/stripe_form.php
