Problem using Curl to login to NYTimes.com

[isogramma]

UPDATE: Turns out my code works. Browser was caching previous failed response. Thanks for the pointers.I'm building a prototype and one thing I'd like to do is perform a service if the user is a valid member of NYTimes.com by providing their credentials. Using curl, I'm trying to perform a login to the site, and then check for success or failure.My code, below, doesn't return errors but drops me back at the login page:\[code\]<?phpclass Login { function Verify() { print $this->getContent(); } function getContent() { $url = 'http://www.nytimes.com/auth/login'; // URI can be any NYT web page to be redirected to upon successful login // SAVEOPTION and Submit2 are Optional but in original web form so included here $fields = array( 'is_continue'=> 'true', 'USERID' => urlencode('ENTER_YOUR_USERNAME'), 'PASSWORD' => urlencode('ENTER_A_PASSWORD'), 'URI' => urlencode('http://www.nytimes.com/robots.txt'), 'OQ' => '', 'OP' => '', 'SAVEOPTION' => 'YES', 'Submit2' => 'Log In' ); $fields_string = ''; if(!$curld = curl_init($url)) { echo "Could not connect to the specified resource"; exit; } $ch = curl_init(); $useragent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1"; foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string,'&'); curl_setopt($ch, CURLOPT_USERAGENT, $useragent); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_COOKIEJAR, "curl_login_cookie.txt"); curl_setopt($ch ,CURLOPT_POST, count($fields)); curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string); ob_start(); curl_exec ($ch); curl_close ($ch); $result = ob_get_contents(); ob_end_clean(); return $result; }}$login = new Login;$result = $login->Verify();?>\[/code\]Any pointers, or suggestions welcome.
