Are you by any chance doing this on a local server, not accessible from the web? IPNs fail in this case because PayPal's response can't be sent to your server.

hi thanks for your reply i m using not local host but live hosting of hostgator and i have resolved my issue after pretty hard work , by the way thanks for ur reply.....

Post here the details if you will, so other may benefit from your insight.

i have changed one thing in his paypal library

// open the connection to paypal
$fp = fsockopen('ssl://'.$url_parsed[host],"443",$err_num,$err_str,30);
//$fp = fsockopen($url_parsed[host],"80",$err_num,$err_str,30);

the commented portion is previous one to which i have replaced with new code

second thing i was making mistake that in function i was handling i was not passing this value

$this->paypal_class->paypal_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr'; // testing paypal url

$this->paypal_class->paypal_url = 'https://www.paypal.com/cgi-bin/webscr'; // paypal url

in his class he has used live ones url by defult and becuase i was not changing

it was always sending validation to live one

but after making these two changes its working all fine


i would like to ask one more question that

this i have set

$this->paypal_class->add_field('return', base_url().'user/regpaysuccess'); // return url
$this->paypal_class->add_field('cancel_return', base_url().'pages/regpaymentcancled'); // cancel url

so at success of payment it should return to first one and at cancel it should return to second one , but its not happening automatically

when i click that return to website it return to success page but i get an alert box like this page is not secure how i can avoid this alert and how it will be automatically rediretd back to my success page after payment done on paypal.....

This is why you setup and get yourself a PayPal Sandbox.

i am using sanbox mode.......

If you're using Chrome, this is a normal alert when redirected to non-ssl site. It can only be removed by installing SSL certificate. Other than that what you can do is to enable auto return, like described here.
