Hi friends,

I use Paypal Sandbox for testing payment process. Payment Works fine coz Money reduced from my paypal personal testing id & increased on my paypal business testing id. But only problem is the I'm not getting my confirmation mail for the payment & database not updating too....

I give some of payment functionality Codes here...

Creating Paypal Form
Code:
function paypal($acctype,$bus_id,$tamt,$type)
    {
            
    /*----------------------------    PAYPAL form   ---------------------------------*/
            
            
            $this->paypal_lib->add_field('business', '[email protected]');
            $this->paypal_lib->add_field('return', site_url('paypal/success'));
            $this->paypal_lib->add_field('cancel_return', site_url('paypal/cancel'));
            $this->paypal_lib->add_field('notify_url', site_url('paypal/ipn'));
            
            $this->paypal_lib->add_field('item_name', "Sample Listing");
            $this->paypal_lib->add_field('item_number', "100");
            $this->paypal_lib->add_field('amount', "500");
            
            $this->paypal_lib->add_field('userid',"10");
        // if you want an image button use this:
            $this->paypal_lib->button('Pay By Paypal');
        
        // otherwise, don't write anything or (if you want to
        // change the default button text), write this:
        // $this->paypal_lib->button('Click to Pay!');
        
              $data['paypal_form'] = $this->paypal_lib->paypal_form();
                        
    /*------------------------------------------------------------------------------*/
        $data['base'] = $this->config->item('base_url');
        $data['css'] = $this->config->item('css');
        $vals=$this->category();
        $data['count']=$vals['count'];
        $data['left_category']=$vals['left_category'];
        
            $this->load->view('paypal',$data);
        
    }

& my Paypal.php file

Code:
class Paypal extends Controller {

    function Paypal()
    {
        parent::Controller();
        $this->load->library('Paypal_Lib');
    }
    
    function index()
    {
        $this->form();
    }
    
    
    function cancel()
    {
        $data['base'] = $this->config->item('base_url');
        $data['css'] = $this->config->item('css');
        $this->load->view('payment_cancel',$data);
    }
    
    function success()
    {
        
        //$data['pp_info'] = $this->input->post();
        $data['pp_info'] = $_POST;
        $this->view('paypal/success', $data);
    }
    
    function ipn()
    {
     $to    = "[email protected]";    //  your email

        if ($this->paypal_lib->validate_ipn())
        {
            extract($_POST);
            $body  = 'An instant payment notification was successfully received from ';
            $body .= $this->paypal_lib->ipn_data['payer_email'] . ' on '.date('m/d/Y') . ' at ' . date('g:i A') . "\n\n";
            $body .= " Details:\n";
            
            foreach ($this->paypal_lib->ipn_data as $key=>$value)
            {
              $body .= "\n$key: $value";
            }

$status=$this->paypal_lib->ipn_data['payment_status'];        
        
if($status='Completed')
