Need some help trying to use curl

[Rifts]

Hey guys I'm trying to log into this website using curl. I did some reading and think I'm pretty close but I cant get the login working It just returns nothing. there is a commented out part which is the page i'm trying to load after I successfully login. 

<?

$username = 'xxxxxxx';
$password = 'xxxxxxx';
$postinfo = "username=".$username."&password=".$password;

$cookie="cookie.txt"; 

$ch = curl_init();

// extra headers
$headers[] = "Accept: */*";
$headers[] = "Connection: Keep-Alive";

curl_setopt($ch, CURLOPT_HTTPHEADER,  $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_URL, 'https://weblogin.asu.edu/cas/login');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postinfo);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie); 


$data = curl_exec($ch);

if (curl_error($ch)) {
    echo curl_error($ch);
}


echo $data;

curl_close($ch);

// //page with the content I want to grab after logging in  (test after login works)
// curl_setopt($ch, CURLOPT_URL, "https://webapp4.asu.edu/myasu/");
// curl_setopt($ch, CURLOPT_POST, false);
// $data = curl_exec($ch);
// if (curl_error($ch)) {
//     echo curl_error($ch);
// }



?>

I'm not sure but I think im maybe missing some other parts the form needs? How do I see exactly what I need to send?

[QuickOldCar]

I do see some hidden values their form as well

<input type="hidden" name="lt" value="LT-124551-2fwqfTISmFTdVpZurniEq1EZD5bVqO" />
<input type="hidden" name="execution" value="e1s1" />

Try this.

<?php
$username = 'xxxxxxx';
$password = 'xxxxxxx';
$postinfo = array(
    "username" => $username,
    "password" => $password
); //now an array
$fields = http_build_query($postinfo); //builds the query
$cookie = "cookie.txt";
$ch = curl_init();

// extra headers
$headers[] = "Accept: */*";
$headers[] = "Connection: Keep-Alive";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_URL, 'https://weblogin.asu.edu/cas/login');
curl_setopt($ch, CURLOPT_POST, count($postinfo)); //counts the array values
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields); //fields added
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
$data = curl_exec($ch);

if (curl_error($ch)) {
    echo curl_error($ch);
}

echo $data;
curl_close($ch);

//page with the content I want to grab after logging in  (test after login works)
/*
curl_setopt($ch, CURLOPT_URL, "https://webapp4.asu.edu/myasu/");
curl_setopt($ch, CURLOPT_POST, false);
$data = curl_exec($ch);
 if (curl_error($ch)) {
    echo curl_error($ch);
}
*/
?>

Trying your code echos back the empty login form and page minus the styling.

 

also what about the hidden vaules?

[QuickOldCar]

Not sure what is needed.

The hidden values could be required, which the value of lt changes each visit.

Or they could even be bot traps, no idea.

 

It seems to me they make efforts to prevent what you are attempting.
