Can't access a page using curl, please help

dMilesFox · December 30, 2008

I'm new on this so I will start...

I'm trying to access a cgi page on another server, this page has a username and password fields, I know I need to call the url on the action and not the page where the form its located. Everything its working fine but, The response I get its, invalid username or password, thats the html msg I got everything I tried to run the script. I think the problem its with a cookie cuz if I tried to access the form manually and set the username and password by hand, I can log in. I took a quick view, and the html form on that page calls a function on the "onsubmit" form tag attribute. This function creates a cookie. That's why I think my curl script its not working.

How can I tell the remote site to set the cookie with curl??? its there any possible way?

Here is the php code

<?php

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://domain.name/path/to/login.cgi');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

$post_data['username']  = 'LOGINNAME';
$post_data['password']  = 'PASSWORD';
$post_data['btnSubmit'] = 'SUBMIT';

foreach ( $post_data as $key => $value) {
	$post_items[] = $key . '=' . $value;
}
$post_string = implode('&', $post_items);

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string); 

$data  = curl_exec($ch);

print_r(curl_multi_getcontent($ch));
curl_close($ch); 


?>

And here is the html form code

<html>
<head>
<meta http-equiv="Content-Language">
<meta http-equiv="Content-Type" content="text/html">
<meta name="robots" content="none">
