Question

My first question on codeigniter. I have integrated paypal in codeigniter using paypal library. everything working fine but when I return to success page then it gave me “An Error Occurred : The action you performed is not valid”. But the same success page is accessible directly from the url (I mean when I put it in the browser directly).

Controller

function form()
{
$this->paypal_lib->add_field('business', '[e-mail]');
$this->paypal_lib->add_field('return', site_url('checkout/paypal/success'));
$this->paypal_lib->add_field('cancel_return', site_url('checkout/paypal/cancel'));
$this->paypal_lib->add_field('notify_url', site_url('checkout/paypal/ipn')); 
$this->paypal_lib->
add_field($this->security->csrf_token_name,   $this->security->csrf_hash); 
}
function success()
{
  echo "success";
}   

Routes

$route['checkout/paypal'] = 'checkout/paypal/index';
$route['checkout/paypal/(:any)'] = "checkout/paypal/$1";

Success page is diretly accessible and prints “success” but when I return from paypal , it gave me “An Error Occurred”

In the apache log..getting 500 572. I am not pretty much sure what it reflects.

Thanks

Open your site’s main configuration file and check your CSRF settings. I had a similar problem once, and it was solved by disabling CSRF protection.

$config['csrf_protection'] = FALSE;

Does that make any difference?
