Automatic login using curl

I am trying to auto login to linked In using curls script.
Below is my script
$userAgent = 'Googlebot/2.1 (http://www.googlebot.com/bot.html)';
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_URL, 'https://www.linkedin.com/secure/login');
curl_setopt ($ch, CURLOPT_POST, 1);

curl_setopt ($ch, CURLOPT_POSTFIELDS, 'session_key=loginemail&session_password=password');

curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

// EXECUTE 1st REQUEST (FORM LOGIN)
$store = curl_exec ($ch);

this is giving the following error;

Make sure you have cookies and Javascript enabled in your browser before signing in.

Any one know what should be the issue?

 

Linkedin have an api, you should use that instead:
http://developer.linkedin.com/index.jspa

 

I think you can't use curl to login on linkedin as they are secure.

Thanks

 

Based on my experience in cURL I would suggest you to use Tamper Data and Web Developer addons in Firefox. I would have given you the script but i don't have a account on Linkedin so i cant make the script. I checked it with Tamper Data. You might not be able to login because in your POSTFIELD you haven't added the value of csrfToken. Open the source and search for "<input type="hidden" name="csrfToken" value= ". The value of this also needs to be passed. Use a preg_match and get it done.
Thanks,
