How do I get my web hosting to connect to Authorize.net using cURL?

Volitics

Hello;

I'm trying to get my web site to connect to the Authorize.net gateway. They (Authorize.net) e-mailed me a script that is supposed to let my web site connect to the Authorize.net gateway.

The cURL part of the script does not seem to be working.

// Note: The values for the array are passed to
// this page from a form on a previous page.
$authnet_values = array("x_login" => $x_login,
"x_tran_key" => $x_tran_key,
"x_version" => $x_version,
"x_delim_data" => $x_delim_data,
"x_delim_char" => $x_delim_char,
"x_relay_response" => $x_relay_response,
"x_amount" => $x_amount,
"x_type" => $x_type);

$fields = ""; // Turns array into string.
foreach( $authnet_values as $key => $value ) {
 $fields .= "$key=" . urlencode( $value ) . "&";
}

// This is supposed to send the data to the Authorize.net server
// and then send back a response - but it doesn't.
$ch = curl_init("https://test.authorize.net/gateway/transact.dll");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, rtrim( $fields, "& " ));
$resp = curl_exec($ch); // It's getting stuck here.
curl_close ($ch);

The script won't connect my web site to the Authorize.net server. It stops executing at the curl_exec($ch) part of the script.

Does anyone have any suggestions about where I might look to troubleshoot to find the problem?

Thanks.

The obvious answer would be to contect THEM. THEY provided you with a script. They should provide support...

Although seeing as you asked here, you should check to see if you have CURL installed by looking at phpinfo()

I sent Authorize.net an e-mail yesterday. They've not responded yet. I'm not sure how much help that they will provide. But I'll keep after them, though.

It's installed.

In the "Configure Command" section it has got " '--with-curl=/usr/bin/curl' "

In the table entitled "curl" it's got the following:
"CURL support enabled"
"CURL Information libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.2.3"

Before I bought the merchant account I sent Authorize.net an e-mail and asked if their gateway would work with my hosting and secure certificate. I have a GoDaddy shared hosting and a GoDaddy secure certificate. Authorize.net responded and said that their gateway would work with the GoDaddy hosting and secure certificate.

The cURL may already do this but what I am starting to wonder is do I need to state the return URL path on my web site in order for the Authorize.net gateway to send the response?
