Как настроить yoomoney для сайта?

Question

[Viva8888]

Здравствуйте. Не добавляются в бд данные транзакции после тестового перевода на юмани.

Мой view

<form method="POST" action="https://yoomoney.ru/quickpay/confirm.xml">    
	<input type="hidden" name="receiver" value="410011xxxx14839">   
	<input type="hidden" name="quickpay-form" value="shop">
	<input type="hidden" name="label" value="<?= $this->session->userdata('id') ?>">
	<input type="hidden" name="targets" value="Тест">  
	<input type="hidden" name="paymentType" value="PC">
	<input  name="sum" value="4568.25" data-type="number" placeholder="Сумма"> 
    
    <input type="submit" value="Перевести">
</form>

Мой контроллер

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

class Yoomoney extends MY_Controller {

	public function __construct()
	{
		parent::__construct();
	}

	public function index()
	{
		
		$this->load->model('yoomoney_model');
		if(isset($_POST['notification_type'])){
			$hash = sha1($_POST['notification_type'].'&'.
			 		$_POST['operation_id'].'&'.
			 		$_POST['amount'].'&'.
			 		$_POST['currency'].'&'.
			 		$_POST['datetime'].'&'.
			 		$_POST['sender'].'&'.
			 		$_POST['codepro'].'&'.
			 		'1vCpCaBwxxxxOEVPmv0l8Vy '.'&'.
			 		$_POST[' label']); 
			if($_POST['sha1_hash'] != $hash || $_POST['codepro'] === true ||  $_POST['unaccepted'] === true) die();
			else{
				// file_get_contents('history.php', 1, FILE_APPEND);
				$add['amount'] = $_POST['amount'];
				$add['user_id'] = $_POST[' label'];
				$add['ps_id'] = 1;
				$this->yoomoney_model->add_transaction($add);
				echo "Успешно";
				die();
			}
		}
		$this->load->view('templates/yoomoney_view');	
	}
}

Модель

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

class Yoomoney_model extends CI_Model {

	public function add_transaction($add)
	{
		$this->db->insert('transactions', $add);
	}
}
