Had trouble on getting return for IPN for paypal so here are the code that might help
So I created a var_dump POST to error log and wrote it down to a text file.
tried error_log($_POST) but it doesn't work...
There's this test tool from paypal sandbox which might help it test the post
ob_start(); var_dump($_POST); $c = ob_get_contents(); ob_end_clean(); $fp = fopen("static/log/paypal_notify.txt", "a"); fwrite($fp, $c); fclose($fp); error_log($c); exit();
Another Method on getting post or get is
