[Resolved] cURL Problems

[bpat1434]

Hey guys.

I have cURL 7.12 installed on my server, and am trying to post variables to another script. So I followed a script found on another forum (one not as good as this), and I get a blank webpage. Any idea what is going on here?

<?php
// This works like a charm!!
$username = $_REQUEST['username'];
$pass = $_REQUEST['password'];

if($username != "owner"){
	$user = $username.'@domain.org';
}
else{
	$user = $username;
}
//======================\\

//This cURL Script doesn't work.
$URL = "webmail.domain.org/index.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://$URL");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "user=$user&pass=$pass");
curl_exec($ch);
curl_close($ch);

?>

I have tried plenty of options to change them like:

// Option 1
curl_setopt($ch, CURLOPT_URL, "http://".$URL);

//Option 2
curl_setopt($ch, CURLOPT_URL, "http://'$URL'");

Applying that to all variable dependent lines of code.

Thanks for the help.

Hi,

what do you see if you just create a HTML page with a form that posts the data to that URL if you click on submit. Reading the code I guess that you want to get the resulting page after logging in into a webmail application.

If you just request that index.php page with your browser ... do you get a login page ? If yes, does the login form point to index.php itself or to another page ?

Another problem could be (not sure) that the script sends a redirect if the login was succesfull, so try to add the option

curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);

Also check if cookies are needed ... you might need to tweak the code a little bit to support cookies in that case.

To see more of what's happening you can use code like this:

$url = 'www.example.com/test.php';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://' . $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'test=this_is_a_test');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  

$curl       = curl_exec($ch);
$curl_info  = curl_getinfo($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);

echo $curl . '<br />';
if ($curl !== false) {
    $curl_return = 'true';
} else {
    $curl_return = 'false';
}
echo '<br /><b>curl_exec()</b> = ' . $curl_return . '<br />';  

echo '<br /><b>curl_errno()</b> = ' . $curl_errno . '<br />';  

If ($curl_error != '') { 
    echo '<br /><b>curl_error()</b> = ' . $curl_error . '<br />';
}  

$tab = '&nbsp;&nbsp;&nbsp;&nbsp;';
echo '<br /><b>curl_getinfo()</b> =<br />';
foreach ($curl_info as $key => $value) {
    echo $tab . $key . ' => ' . $value;
    echo '<br />';
}

Ok, so the page to redirect to was incorrect. Now that I've redone that....

I now get a page saying that the URL /redirect.php can not be found on the server.

So the script is running, but I don't know why it won't go to the sub-domain.

Is there something else I need to add for sub-domain control?

Thanks for the help.

The curl script seems to be working as it should, so I'd say the problem is on the server end. The 404 is issued by the web server, so apparently it's getting the request and looking for "redirect.php" and not finding it. If the subdomain were not being found you should be getting a dns error instead. I'd have to say that the most likely cause of the problem is that "redirect.php" isn't there.

Thanks for the help.

It was actually that the page I needed to load was under a directory (forgot about it). Now it's just a matter of getting SquirrelMail to cooperate.

Thanks for the help!!
