Curl doesn't write on file cookie - php

Question

I'm trying to login to my website using curl all is working fine, the only problem is when I open the file cookie.txt I find it empty this is the code that I tried:
<?
$url = "http://security-dz.com/wp-login.php"; // URL
$POSTFIELDS = 'log=testtest&pwd=test1234';
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4)
Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
I created a file called cookie.txt at the same folder, but when I'm runing this code i can access my website normally the only problem is when i open the file cookie.txt it is empty so what i can do about this?

Answer 1

If you want to get full path you can use this way to.
$cookie=dirname(__FILE__)."\\cookie.txt";
so you can just use this way.
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
it work for me

Try this:
<?
$url = "http://snipercoder.com/wp-login.php"; // URL
$POSTFIELDS = 'log=testtest&pwd=test1234';
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4)
Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS);
curl_setopt($ch, CURLOPT_COOKIEFILE, "C:/yourfolderserver/www/cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "C:/yourfolderserver/www/cookie.txt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>

Answer 3

CURLOPT_COOKIEFILE/CURLOPT_COOKIEJAR options must be set with absolute path value. "cookie.txt" is a relative path.

Answer 4

If you are in a localhost try this:
<?
$url = "http://security-dz.com/wp-login.php"; // URL
$POSTFIELDS = 'log=testtest&pwd=test1234';
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4)
Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$POSTFIELDS);
curl_setopt($ch, CURLOPT_COOKIEFILE, "C:/wamp/www/cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "C:/wamp/www/cookie.txt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
