curl login into website not working

brvnbld · December 4, 2014

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.

no dude, this doesn't work either

brvnbld · December 4, 2014

i have tried all options to the curl url, like index.php?action=login, logon, etc...

Even if i change the curl url to something meaningless, it still displays the same result.

QuickOldCar · December 4, 2014

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");

QuickOldCar · December 4, 2014

btw, should place the header at the end so curl can close

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

still the same error.

yeah buddy, corrected that, but still i get the same result.

QuickOldCar · December 4, 2014

Show the full form and the php code that checks it

brvnbld · December 4, 2014

ok., html code.


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

<div style="border:1px solid #000000;background:#EEEEEE;padding-top:15px;padding-bottom:5px;width:350px;">
<font size=+2>Sign In Form</font><br>

<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>
</table>
</form>
</div>
<br>
</center>
</body>
</html>

the php code is same, i posted the entire php page.

QuickOldCar · December 4, 2014

When you send your post form, where does it get the $_POST values in a php script?

That's the part not shown.

brvnbld · December 4, 2014

the html code i pasted is from another site, i am trying to login in to another site using a php page.

brvnbld · December 4, 2014

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');
}
?>

where do i put the username and password?

QuickOldCar · December 4, 2014

Point the form to other site where the curl script is

With no action posts to same page.

<form action="http://www.example.com/index.php" method="post">

QuickOldCar · December 4, 2014

You put the username and password in the form, the form sends to your curl script

brvnbld · December 4, 2014

The curl script is in my site, the login form is another website, it belongs to someone else,

i do not understand how i point the form to the curl site.?

brvnbld · December 4, 2014

how do i edit someone else's form?, the html code i posted , i took it by going to that site, and selecting view source.

QuickOldCar · December 4, 2014

make your own login form your site which points to the curl script your site

the curl url location would be theirs

QuickOldCar · December 4, 2014

Note these lines to edit

$url="http://other-site.com/login.php";

I hope this helps

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.

brvnbld · December 4, 2014

no, dude, that doesn't work either, it again shows me the track.html i called at the end, but just not logged in.

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. ::)

Does this other site require a cookie or anything?

You see the other site and what happens when logs in, hard to help beyond what I tried.
