Posting form info using Curl

[brij_theinvader]

hi,
here below is the script that i wrote to pass information of the form to the URL.
But the problem is that, the return page is showing me " Your session has expired".
So please suggest some solution to this:

<?php

$post_data = array();
$post_data['firstname'] = "abc";
$post_data['lastname'] = "deg";
$post_data['snumb'] = "adafd";
$post_data['anumb2'] = "adfa";
$post_data['city'] = "Newyork";
$post_data['state'] = "Newyork";
$post_data['zip'] = "43234223";
$post_data['country'] = "USA";
$post_data['phone'] = "4134134143";
$post_data['email'] = "[e-mail]";
$post_data['userid'] = "";
$post_data['password'] = "";
$post_data['submit'] = "Continue";
$post_data['amount'] = "5";
$post_data['recurring'] = "off";
$post_data['s_recurring'] = "";
$post_data['designategift2'] = "society upliftment";
$post_data['ShareBox'] = "GiveNameEmail";
$post_data['Option'] = "";
$post_data['submit1'] = "Donate Now";
$post_data['onBehalf_Name'] = "";
$post_data['onBehalf_email'] = "";
$post_data['Matching_Company'] = "";
$post_data['Matching_Email'] = "";
$post_data['cardType'] = "Visa";
$post_data['cardNum'] = "232325433453435343";
$post_data['cardExpMo'] = "08";
$post_data['cardExpYr'] = "10";

$url = "http://www.nycharities.org/donate/processtransaction_new.asp";

$o="";
foreach ($post_data as $k=>$v)
{
    $o.= "$k=".utf8_encode($v)."&";
}
$post_data=substr($o,0,-1);

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$result = curl_exec($ch);
echo $result;

?>

I know the pages , which are at present passing the information to this page. So, is it possible to get the session id from there?

You'll have to look on the page for [man]curl_setopt/man for the correct usage, but if there's a certain page that generates a session id, then I believe you can use the CURLOPT_COOKIEJAR option to capture any cookies sent by the server into a local file. Then, you'd use the CURLOPT_COOKIEFILE to specify where this file is located so that your POST operation includes any cookies started from the last page.
