cURL - Not Working - WARNING: failed to save cookies in cookie.txt

问题

I'm totally new to cURL but here's what I'm wanting to do:

One of my suppliers has a product feed that I can download once I login to their site. This is ok but I want to automate it so I've tried to put the following script together (google and Stack info) - I've changed the username and password for security reasons but I'm 100% sure they're correct:

<?php

//The username or email address of the account.
define('USERNAME', 'myusername');

//The password of the account.
define('PASSWORD', 'mypassword');

//Set a user agent. This basically tells the server that we are using Chrome ;)
define('USER_AGENT', 'Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.2309.372 Safari/537.36');

//Where our cookie information will be stored (needed for authentication).
define('COOKIE_FILE', '/cookie.txt');

//URL of the login form.
define('LOGIN_FORM_URL', 'https://www.treatgifts.com/customer/sign-in.aspx');

//Login action URL. Sometimes, this is the same URL as the login form.
define('LOGIN_ACTION_URL', 'https://www.treatgifts.com/customer/sign-in.aspx');


$f = fopen('log.txt', 'w'); // file to write request header for debug purpose


//Get __VIEWSTATE & __EVENTVALIDATION

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, USER_AGENT);

$html = curl_exec($ch);

curl_close($ch);

preg_match('~<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="(.*?)" />~', $html, $viewstate);
preg_match('~<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="(.*?)" />~', $html, $eventValidation);

$viewstate = $viewstate[1];
$eventValidation = $eventValidation[1];

$f = fopen('log.txt', 'w'); // file to write request header for debug purpose


 //Start Login process

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, LOGIN_FORM_URL);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);
curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_FILE);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_REFERER, LOGIN_FORM_URL);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_STDERR, $f);
curl_setopt($ch, CURLOPT_USERAGENT, USER_AGENT);

// Collecting all POST fields
$postfields = array(
    'ctl00$BodyContentHolder$ucSecureSignInPrompt$txtCustomerEmail' => USERNAME,
    'ctl00$BodyContentHolder$ucSecureSignInPrompt$txtCustomerPassword' => PASSWORD,

'tl00$BodyContentHolder$ucSecureSignInPrompt$btnLogin'=>'LOGIN',
    'ctl00$BodyContentHolder$ucSecureSignInPrompt$txtCustomerEmail' => USERNAME,
    'ctl00$BodyContentHolder$ucSecureSignInPrompt$txtCustomerPassword' => PASSWORD,
'ctl00$ToolkitScriptManager1'=>'ctl00$BodyContentHolder$CartStatusUpdatePanel|ctl00$BodyContentHolder$ucSecureSignInPrompt$btnLogin'


);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$ret = curl_exec($ch); // Get result after login page.
print $ret; ?>

When I run the code it just directs me to the login page, without logging me in. I write the log to a file and here is what I get:

* WARNING: failed to save cookies in cookie.txt

As you can see there is a warning at the bottom, which I suspect is causing the issue? What I've tried to do to fix this is:

manually create cookie.txt andgive it 777 permissions.
use the absolute path

None of these have worked.

I also don't see a POST command in console

Can anyone offer any advise?

Thanks Chris
