php - Paypal IPN Sandbox - IPN Listener - no verified or invalid -

i have set test accounts business , personal in developer trying out sandbox mode.

i have made payment button on site. click button , go paypal. test user personal account used paying. payment goes through , completed when in paypal business account. redirect site works good.

so in eyes should have "working" system.

my ipn listener though not return either verified or invalid.

this listener:

 <?php  require("../widgets/init.inc.php");  //test script launced $log_query = mysql_query("insert `log` values (' ','zz','ff','rr', 'rr')");                  // link paypal codes // // https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_id=developer/e_howto_html_ipnandpdtvariables //   // read post paypal system , add 'cmd' // $req = 'cmd=_notify-validate';  foreach ($_post $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; }  // post paypal system validate // $header .= "post /cgi-bin/webscr http/1.0\r\n"; $header .= "content-type: application/x-www-form-urlencoded\r\n"; $header .= "content-length: " . strlen($req) .

i have activated ipn @ paypal business account site. have made txt file of returned information paypal, , looks this:

it seems lot harder work think should be.

i found problem.. , annoying thing paypal documentation wrong again.. don't understand documentation can state press button , press button.. when there no buttons in site...

for problem - documentation state wrong method / not include full code needed.

the problem: $res returned this:

http/1.0 400 bad request server: bigip connection: close content-length: 19 invalid host header 

what needs added :

$header .= "host: www.sandbox.paypal.com\r\n"; 

and above code looks this:

// post paypal system validate // $header .= "post /cgi-bin/webscr http/1.0\r\n"; $header .= "host: www.sandbox.paypal.com\r\n"; $header .= "content-type: application/x-www-form-urlencoded\r\n"; $header .= "content-length: " . strlen($req) . "\r\n\r\n"; $fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); 

this full code ended using:
