POSTing Form Data and Storing Cookie File with PHP Curl - php

Question

$process = curl_init();
$temporary_cookie_file = 'temporaryfiles/'.strtolower($user_general_information['Username']).'_cookies.txt';
$temporary_cookie_file_handler = fopen($temporary_cookie_file, 'w');
fclose($temporary_cookie_file_handler);
$user_data = array('TCNK'=>'authenticationEntryComponent', 'submitEvent'=>'1', 'guestLoginEvent'=>'', 'enterClicked'=>'true', 'bscf'=>'', 'bscv'=>'', 'targetEntid'=>'', 'ajaxSupported'=>'yes', 'screenName'=>$user_general_information['Username'], 'kclq'=>$user_general_information['Password']);
curl_setopt($process, CURLOPT_URL, 'https://www.edline.net/post/InterstitialLogin.page');
curl_setopt($process, CURLOPT_USERAGENT, 'Chrome/12.0.742.122');
curl_setopt($session, CURLOPT_POST, true);
curl_setopt($session, CURLOPT_POSTFIELDS, http_build_query($user_data));
curl_setopt($process, CURLOPT_TIMEOUT, 0);
curl_setopt($process, CURLOPT_RETURNTRANSFER, true);
curl_setopt($process, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($process, CURLOPT_COOKIEJAR, realpath($temporary_cookie_file));
curl_setopt($process, CURLOPT_COOKIEFILE, realpath($temporary_cookie_file));
curl_setopt($process, CURLOPT_HEADER, false);
$results_1 = curl_exec($process);
var_dump($results_1);
die();
I am trying to use POST form data to log into a site and then store the created cookies in a temporary file. I've looked at other discussions that talk about doing this and did as them but it doesn't work. When I try, it simply refreshes the page with no changes. I've been working on this for hours...Any ideas of what I am doing wrong?
