curl login into website not working

Recommended Posts

I am trying to create a remote login to one website using mine. The users will need to enter their username and password on my site, and if they are registered to my website, their login credentials will be sent to another website and a page will be retrieved.

I am stuck at sending the users' data to the original site. The original site's viewsource is this..

<form method=post>
<input type="hidden" name="action" value="logon">
<table border=0>
<tr>
<td>Username:</td>
<td><input name="username" type="text" size=30></td>
</tr>
<tr>
<td>Password:</td>
<td><input name="password" type="password" size=30></td>
</tr>
<td></td>
<td align="left"><input type=submit value="Sign In"></td>
</tr>
<tr>
<td align="center" colspan=2><font size=-1>Don't have an Account ?</font> <a href="?action=newuser"><font size=-1 color="#0000EE">Sign UP Now !</font></a></td>
</tr>
</table>

I have tried this code, but not works.

<?php
$username="username"; 
$password="password"; 
$url="http://www.example.com/index.php"; 

$postdata = "username=".$username."&password=".$password;

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 
header('Location: track.html'); 
//echo $result;  
curl_close($ch);
?>

Any help would be appreciated, Thanks in advance.

I don't see the rest of your form, but how about adding the submit or whatever you may be checking for in your script.

$postdata = array("username"=>$username, "password"=>$password, 'submit' => "submit");

 

This is the whole form, and about the html code, the rest are just head and html tags anyway.

still the same error.

<link rel="stylesheet" href="styles/main.css" type="text/css" media="print, projection, screen">

i think i was not clear.

 

I have a website, users will login to my site, and in return their details will be sent to the other site, and they will get a iframed version of the other site. 

 

i am trying to achieve this by creating a login form on my website, then logging in to other site using the data provided by the user by curl, then display the original site, in iframes.

Correct, and you are not getting the $_POST values anywhere

<?php
if(isset($_POST['username']) && trim($_POST['username']) !=''){
$username = trim($_POST['username']);
}
if(isset($_POST['password']) && trim($_POST['password']) !=''){
$password = trim($_POST['password']);
}
if(isset($_POST['action']) && trim($_POST['action']) !=''){
$action = trim($_POST['action']);
}

if(isset($username) && isset($password) && isset($action)){
$url="http://www.example.com/index.php";
$postdata = array("username"=>$username, "password"=>$password, "action" => $action);
$fields = http_build_query($postdata); //builds the query
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
$result = curl_exec ($ch);
//echo $result;
curl_close($ch);
header('Location: track.html');
} else {
die('Parameters missing');
}
?>

A lot of people are untrusting to log into a site using another.

 

Am trying to understand why you would iframe another site versus them just visiting the original site.

 

 

The fact is, i have a website, that provides work, and i have employers who can work, but if they see the original site, they will stop working for me, that is why. ::)
