$post_values["PaymentOtherOnline"] 		= "";

$postfields = 'turboconv=1';

curl_exec($ch);
// transfer auction

Hi!

I'm trying to login to a script wich redirects the user to an OK URL upon success to wich I would like to post variables to, anyone knows how to do it (within the same $ch session) ?

most likely you will need to initiate a new session using the new cookies in order to post to a second url after the sucessful login.
thats how i do it at least.

in the past to simplify gets and posts, ive wrapped curl into an easy function. maybe you can utilize it in a way...

function curl_post( $postUrl, $postData, $username, $referer = "http://www.site.com/default.phtml" )
{
  global $headers;

  $ch = curl_init($postUrl);
  curl_setopt($ch, CURLOPT_REFERER, $referer);
  curl_setopt($ch, CURLOPT_USERAGENT, USER_AGENT);
  curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_PATH . $username . ".txt");
  curl_setopt($ch, CURLOPT_COOKEJAR, COOKIE_PATH . $username . ".txt");
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
  $data = curl_exec($ch);
  curl_close($ch);

  return $data;
}

what i used for the $headers is
$headers[] = "Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg";
$headers[] = "Connection: Keep-Alive";
$headers[] = "Content-type: application/x-www-form-urlencoded";

basically call the function like this:

$output = curl_post("http://www.site.com/loginscript.php", "username=xxx&password=yyy&action=login", "myusername", "http://www.site.com/login.html");

obviously you can have as many curl_post's in one script as you like, either one after the other or spread around as needed.

the $username paramater i put in so i could have multiple users logged in at any given time, but you may be able to safely remove that.

Hi!

Thanks for the extensive reply! 🙂

What I meant was if it is possible to post variables to an inner redirected URL, e.g. POST_1 -> login.php wich redirects to script.php?login_id=uniqueIDxxx

$post_values["ShipTermsSeeDescription"] 	= 1;
$post_values["CheckoutInstructions"] 		= "";

$postfields = 'turboconv=1';
foreach ($post_values as $fieldname => $value) {
	if (is_array($value)) {
		foreach ($value as $n => $valuevalue) {
			$postfields.="&".$fieldname."[]=".$valuevalue;
		}
	} else {
		$postfields.="&".$fieldname."=".$value;
	}
}

$id = "xxx"; 
$pw = "xxx"; 
$login_values["request_uri"] 	= "/super/lister/index.php?c=onest_one";
$login_values["username"] 	= $id;
$login_values["passwd"] 		= $pw; 

$loginfields = 'action=login';
foreach ($login_values as $fieldname => $value) {
	if (is_array($value)) {
		foreach ($value as $n => $valuevalue) {
			$loginfields.="&".$fieldname."[]=".$valuevalue;
		}
	} else {
		$loginfields.="&".$fieldname."=".$value;
	}
}


$headers[] = "Accept: image/gif, image/x-bitmap, image/jpeg, image/pjpeg"; 
$headers[] = "Connection: Keep-Alive"; 
$headers[] = "Content-type: application/x-www-form-urlencoded"; 

function curl_post( $postUrl, $postData, $username, $referer = "http://www.inkfrog.com/" ) 
{ 
  global $headers; 

  $ch = curl_init($postUrl); 
  curl_setopt($ch, CURLOPT_REFERER, $referer); 
  curl_setopt($ch, CURLOPT_USERAGENT, USER_AGENT); 
  curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_PATH . $username . ".txt"); 
  curl_setopt($ch, CURLOPT_COOKEJAR, COOKIE_PATH . $username . ".txt"); 
  curl_setopt($ch, CURLOPT_POST, 1); 
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); 
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
  $data = curl_exec($ch);
  curl_close($ch); 

  return $data; 
}



$output = curl_post("http://toad8.inkfrog.com/main_login.php?action=login", $loginfields, "inkfrog", "http://toad7.inkfrog.com/super/lister/index.php?c=onest_one");

$output = curl_post("http://toad7.inkfrog.com/super/lister/index.php?c=onest_one", $post_values, "inkfrog", "http://toad8.inkfrog.com/main_login.php?action=login");

print $output;

Anyone knows a solution ?

im not 100% sure what you mean by saying " if it is possible to post variables to an inner redirected URL, e.g. POST_1 -> login.php wich redirects to script.php?login_id=uniqueIDxxx"

i think what they are doing is after a sucessful login, it redirects your browser to some welcome page, where you can do other actions right? if you want to post to the script.php it is possible to directly post to it after you have the login credentials needed.

one useful tool for trying to debug what values a browser sends to a form so you can emulate it is called livehttpheaders. it works for mozilla and mozilla firefox and is a plugin that shows you the actual get an post requests your browser makes to a webpage, and it also shows the responses sent by the remote server. it can make it very easy to just copy the requests over.
if you want to try it download it from livehttpheaders.mozdev.org
set the exclude urls filter to .gif$|.jpg$|.ico$|.css$|.js$ as found in the config tab and then make your requests.

hopefully that can help you out if i didnt.
