Thank you Chad for such a useful functions and support for beginners.
I have 2 main problems now.
1. The login doesnt work.
I was trying to detect the error, and I think it is because the cookie file keeps being empty. I have the test files on a XAMPP directory on my desktop PC, with WinXP SP2, on a NTFS partition. I have Administrative privileges. As you will see, I open 2 files, one for error reporting and the other one for cookies. The error reporting file is being opened without problems by curl, because I give it a handle to an open file. However for cookies I give a filename, so I dont know if curl can write to that file.
2. The images on the target site have relative paths, so they wont show on my browser via curl. I think this is not so difficult to fix, but I am new to curl, so please enlighten me where should I look for a solution.
Besides, I would like to know if it is possible to give curl a variable instead of a filename for cookie options. Because I would like to redirect the cookies to the end user, instead of storing them on the server. Something like this:
SITE ---- [login_cookie]----> PHP/CURL setrawcookie() ---- [login_cookie] ----> END USER
Thank you very much again, I would appreciate a lot if you can give me some advice.
Roman.
Here is my test code:
PHP Code:
<?php
define(DEBUG_MODE, TRUE);
error_reporting(E_ALL | E_STRICT);
$my_mundo_travian = 'http://s1.travian.net';
$my_login_url = "$my_mundo_travian/dorf1.php";
/* below the original test page has a string with valid header data copied as
shown in the tutorial using live http headers */
$my_login_data = "";
$my_proxy = '';
$my_proxy_status = 'off';
/* after a successful login, this url shows the initial game control panel.
If login fails, it shows the login page */
$my_grab_page = 'http://s1.travian.net/dorf1.php';
$fp_err = fopen("curl_errors.txt", "w");
curl_login($my_login_url, $my_login_data, $my_proxy, $my_proxy_status);
echo curl_grab_page($my_grab_page, $my_proxy, $my_proxy_status);
fclose($fp_err);
/* login functions by Chad from http://codersshack.com/forums/php_11/tutorial-curl-login_44.html */
/* functions are slightly modified in order to send curl verbose report to a file */
function curl_login($url,$data,$proxy,$proxystatus){
global $fp_err;
$fp = fopen("cookie_travian.txt", "w");
fclose($fp);
$login = curl_init();
if (DEBUG_MODE) {
curl_setopt($login, CURLOPT_VERBOSE, TRUE);
curl_setopt($login, CURLOPT_STDERR, $fp_err);
}
curl_setopt($login, CURLOPT_COOKIEJAR, "cookie_travian.txt");
curl_setopt($login, CURLOPT_COOKIEFILE, "cookie_travian.txt");
curl_setopt($login, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; es-ES; rv:1.8.1.4) Gecko/20070515 Firefox/2.0.0.4");
curl_setopt($login, CURLOPT_REFERER, "http://s1.travian.net/dorf1.php");
curl_setopt($login, CURLOPT_TIMEOUT, 30);
curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'on') {
curl_setopt($login, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($login, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($login, CURLOPT_PROXY, $proxy);
}
curl_setopt($login, CURLOPT_URL, $url);
curl_setopt($login, CURLOPT_HEADER, TRUE);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($login, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_POSTFIELDS, $data);
ob_start(); // prevent any output
return curl_exec ($login); // execute the curl command
ob_end_clean(); // stop preventing output
curl_close ($login);
unset($login);
}
function curl_grab_page($site,$proxy,$proxystatus){
global $fp_err;
$ch = curl_init();
if (DEBUG_MODE) {
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_STDERR, $fp_err);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'on') {
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie_travian.txt");
curl_setopt($ch, CURLOPT_URL, $site);
ob_start(); // prevent any output
return curl_exec ($ch); // execute the curl command
ob_end_clean(); // stop preventing output
curl_close ($ch);
}
?>
