Hi,

I got a problem im trying to get the the post value from the do_purchase function to the function redirect.

Here my code im using a paypal libary

Code:

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

class Home extends CI_Controller {


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

public function index()
{
  $this->load->view('view_home');
}

public function do_purchase(){

  $this->load->helper('string');
  
  $config['business']    = 'myemail';
  $config['cpp_header_image']  = 'test'; //Image header url [750 pixels wide by 90 pixels high]
  $config['return']     = 'http://localhost/test/home/redirect/';
  $config['cancel_return']   = 'http://localhost/codeigniter_lab/payments/cancel_payment';
  
  $config['production']    = FALSE; //Its false by default and will use sandbox
  $config["invoice"]    = random_string('numeric',8); //The invoice id
  
  $this->load->library('paypal',$config);
  
  $price = $this->input->post("myselect");
  
  $this->paypal->add('test',$price,1);
  
  $this->paypal->pay();
  
  
}

public function submitting()
{
  $this->do_purchase();
}

public function redirect ()
{
  if($this->input->post())
  {
   echo $price;
    
  }else{
   echo "false";
  }
}


}
