Curl error: couldn't connect to host in .../WHMCS/Terminus.php on line 0

[Mike_B]

Hello,

 

I'm using the API functions to add a client, add an order and capture payment. Things were working fine but now I'm getting the following error after making the call to add an order.

 

Fatal error: Curl error: couldn't connect to host in .../includes/classes/WHMCS/Terminus.php on line 0

 

This isn't $results['message'] but the first element of an array. Here's the vardump of $results

 

array(1) { [" Fatal error: Curl error: couldn't connect to host in .../includes/classes/WHMCS/Terminus.php on line 0 "]=> NULL }

 

Despite this error, when I view the client list the client has been added as well as the order for that client. The invoice is generated too. Unfortunately, the return is not "success".

 

I've read many pages that mention to whitelist the IP or talk about a firewall or port issue. The IP has been whitelisted. The server admin states that the server WHMCS is on hasn't been updated or changed for days before this issue arose. Also tried many different curl options and tested bare bones API access with hard coded client details. Anyone know what's going on here?

 

My workaround has been to make a call to get the client details for the new client and pluck the invoice id out of that. Then I make a call to capture payment with that invoice id. It works but it's sloppy and can't stay this way.

Hi

 

Can you post here the full code that your are using to send the API request?

 

p.s. Remember to replace your username, password, host and accesskey (if in use) with lot of "XXX"

This is the bare bones code with most of it pulled from the WHMCS docs.

 

$success= []; // used to check results

$url = "https://.../api.php";
$username = "...";
$password = "...";

$postfields["username"] = $username;
$postfields["password"] = md5($password);

$postfields["action"] = "addclient";
$postfields["firstname"] = 'firstName';
$postfields["lastname"] = 'lastName';
$postfields["email"] = 'test@test.com';
$postfields["address1"] = '55 Road Rd.';
$postfields["city"] = 'Las Vegas';
$postfields["state"] = 'Nevada';
$postfields["postcode"] = '89135';
$postfields["country"] = 'US';
$postfields["phonenumber"] = '702-555-1212';
$postfields["password2"] = 'password';
$postfields["cctype"] = 'Visa';
$postfields["cardnum"] = 4111111111111111;
$postfields["expdate"] = 1116;
$postfields["cvv"] = 123;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$data = curl_exec($ch);
curl_close($ch);

$data = explode(";",$data);
foreach ($data AS $temp) {
$temp = explode("=",$temp);
$results[$temp[0]] = $temp[1];
}

if ($results["result"]=="success") {
# Result was OK!
$success[] = 'client added';
$postfields["clientid"] = $results["clientid"];
unset ($results);
} else {
# An error occured
echo "The following error occured: ".$results["message"];
}

$postfields["action"] = "addorder";
$postfields["pid"] = 47;
$postfields["billingcycle"] = "Monthly";
$postfields["paymentmethod"] = "paypal";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$data = curl_exec($ch);
curl_close($ch);

$data = explode(";",$data);
foreach ($data AS $temp) {
$temp = explode("=",$temp);
$results[$temp[0]] = $temp[1];
}

if ($results["result"]=="success") {
# Result was OK!
$success[] = $results;
} else {
# An error occured
var_dump($results);
}

var_dump($success);

I see that you are sending multiple API requests then in this case the second request (addorder) can't be completed. Before you run the addorder, try to unset($postfields); and re-declare username and password. It should fix your problem.

[Mike_B]

I also thought multiple calls might conflict but I just tested with the following. It only adds the order to an existing client. It did add the order and generated an invoice but still returned the same error.

 

$success= []; // used to check results

$url = "https://.../api.php";
$username = "...";
$password = "...";

$postfields["username"] = $username;
$postfields["password"] = md5($password);


$postfields["action"] = "addorder";
$postfields["pid"] = 47;
$postfields["billingcycle"] = "Monthly";
$postfields["paymentmethod"] = "paypal";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
$data = curl_exec($ch);
curl_close($ch);

$data = explode(";",$data);
foreach ($data AS $temp) {
   $temp = explode("=",$temp);
   $results[$temp[0]] = $temp[1];
}

if ($results["result"]=="success") {
   # Result was OK!
   $success[] = $results;
} else {
   # An error occured
   var_dump($results);
}

var_dump($success);
