PayPal IPN Response Blank

[aj_nsc]

It's happening in paypal_ipn.php, like I said. Post the current code from paypal_ipn.php and I can point it out to you.

You have to have test mode enabled in 2 different places - during your initial checkout (which works because you said you are going to the sandbox site to checkout) AND ALSO in the script where you are asking PayPal to validate your IPN - this is paypal_ipn.php where test mode is not enabled, currently.

$config['paypal_test'] = true; 
if($config['paypal_test'] == 'true'){ $p->enableTestMode(); } 

This will not execute because $config['paypal_test'] is equal to boolean true, not the string true.

Why not just do

$p->enableTestMode(); 

With no conditional around it whatsoever so you are 100% certain that it will request sandbox.paypal.com?

Also, check your log file if it still doesn't work, the first line should have the URL:

www.sandbox.paypal.com

NOT

www.paypal.com

Now I cant even submit the payment. When I hit send payment it just reloads the payment details page.....

Sometimes I will get this message

Bad Request

Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

Apache Server at www.sandbox.paypal.com Port 443

[aj_nsc]

Editing paypal_ipn.php has nothing to do with submitting the payment whatsoever.

Everything went haywire due to a strange problem with cookies on my browser but I got that fixed.

I added the code to paypal_ipn.php and it is now going to sandbox.paypal.com but the IPN is still failing!

Fantastic, you're getting much closer with the trivial errors out of the way. I found the following thread on stackoverlow which will help you:

http://stackoverflow.com/questions/8...302-in-sandbox

They apparently recently changed the URL's to use ssl:// and port 443. Post back here if you've got any questions on how to implement it.

Thanks for sticking with me.

[Master00]

Ahhh, yes!

There we go, it works. Thanks a lot!

Now, I just hope I don't run into this much trouble when I go live........

My one seen don't work ? It don't show me the amount to be paid when I log into sandbox. The testing transaction is not executed.

[aj_nsc]

If you want us to look at code, you have to actually post it (not a link to it) - posting a link to a PHP script executes it.

Also, start your own thread so your question can get it's own exposure rather than burying it in this thread.
