cURL won't trigger setcookie - php

Question

I have a cURL script that is sending login info to a script.
//open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url;
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields1);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
//open connection
The script has a setcookie function.
setcookie("cookie_email",$email,time()+(3600*24*$i),"/");
setcookie("cookie_password",$password,time()+(3600*24*$i),"/");
When I login to the form using the form everything works as expected. For some reason when you run the cURL it's skipping the setcookies function.
I've been all over the net and I can't find a solution. I'm not sure why it's failing to set the cookies.
Any step in the right direction would be much appreciated.
Thanks,
Phil
UPDATE! - Getting Closer
Okay I have made some changes that grab cookies and put them into a cookie file. Two Issues I set.
1. The cookied password in the file reads: deleted
2. The cookies aren't being set in the browser.
How do I get the md5($password) into the file and how does:
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies/cookies.txt');
set the cookies in the browser?

Answer 1

You must set the CURL_COOKIEJAR and CURL_COOKIEFILE options for curl to set where cookies should be stored and loaded from respectively.
EDIT: Your example rewritten:
//open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url;
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields1);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies/cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies/cookies.txt');
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
This assumes you have created a directory 'cookies/' and will save the cookies in a file called 'cookies.txt' (as long as your webserver can write to that directory, it will create the file itself)
Subsequent requests will then use any cookies stored in cookies.txt when sending their request (assuming you set the cookiefile for that request as well)
