// generate the post string from the _POST vars aswell as load the
// _POST vars into an arry so we can play with them from the calling
// script.
$post_str = '';
foreach ($_POST as $field=>$value) {
$this->ipn_data["$field"] = $value;
$post_str .= $field.'='.urlencode(stripslashes($value)).'&';
}
$post_str.="cmd=_notify-validate"; // append ipn command
// open the connection to paypal
$fp = fsockopen($url_par[host],"80",$errnum,$errstr,30);
if(!$fp) {
// could not open the connection.
return false;
} else {
// Post the data back to paypal
fputs($fp, "POST ".$url_par[path]." HTTP/1.1\r\n");
fputs($fp, "Host: ".$url_par[host]."\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ".strlen($post_str)."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $post_str . "\r\n\r\n");
// loop through the response from the server and append to variable
while(!feof($fp)) {
$this->validate_ipn_response .= fgets($fp, 1024);
}
fclose($fp); // close connection
}
if (eregi("VERIFIED",$this->validate_ipn_response)) {
return true;
