curl stuck on same page - php

Question

I am trying to login to a page, and then go to a different page, submit a form, and then I get another form on the same link, submit that, and then get another form on the same link, and submit that.
However, from what I see, I login fine ... but after that it keeps showing me the same page (the one after I login).
$username = 'xxxxxxx';
$password = 'yyyyyyy';
$useragent = $_SERVER["HTTP_USER_AGENT"];
$fields = array(
'username='. urlencode($username),
'password=' . urlencode($password),
);
$postdata = implode('&', $fields);
$ch = curl_init();
//Main Login
curl_setopt ($ch, CURLOPT_URL,"https://xxxxxxxxxxxx.com/index.php");
curl_setopt ($ch, CURLOPT_HEADER, true);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt ($ch, CURLOPT_REFERER, "https://xxxxxxxxxxx.com/index.php");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
echo $result;
echo "<pre>";
print_r ($info);
echo "</pre>";
print curl_error($ch);
$contractid = "12345";
$fields = array(
'contract_id='. urlencode($contractid),
'submit='. urlencode("Next"),
);
$postdata2 = implode('&', $fields);
curl_setopt ($ch, CURLOPT_URL,"https://xxxxxxxxxxxx.com/index.php?page=Recovery");
curl_setopt ($ch, CURLOPT_HEADER, true);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt ($ch, CURLOPT_REFERER, "https://xxxxxxxxxxxxx.com/index.php?page=Recovery");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata2);
curl_setopt ($ch, CURLOPT_POST, 1);
$result_2 = curl_exec($ch);
$info = curl_getinfo($ch);
echo $result;
echo "<pre>";
print_r ($info);
echo "</pre>";
print curl_error($ch);
and twice more for each step, the same way and ending it with curl_close($ch);.
However, like I stated, it still shows only the main page.

After first curl request close curl and initialize again. Otherwise curl will not write anything to cookie file and at next call no cookies are sent!
CURLOPT_COOKIEJAR
The name of a file to save all internal cookies to when the handle is
closed, e.g. after a call to curl_close.
// after end of first curl call
curl_close($ch);
// before second curl call
$ch = curl_init();
