HappyFox allows users to create both Ticket & Contact custom fields. These custom fields can be of different types ranging from Text, Number, Date to Multiple-Option. In this article, let us explore how a Multiple-Option custom field can be set via API using PHP. 


Sample Multiple-Option custom field


An important thing to remember about multiple-option fields is that they behave similar to lookups/drop-down. When we try to set them via API, we need to pass the “Id” of the lookup values that we have created and not the actual lookup-value itself. 

In the sample screen above, if we need to select the following values for Multiple-Option field “Additional Services”

  • Refuel

  • Thruster Cleanup

  • Shield Verification

We need to be using the corresponding Id values in API i.e


Note that the indexing starts from 1 onwards.

So let us consider the scenario where we try to create a ticket via API using a PHP script and we would like to set this multiple-option field “Domain” during creation itself. 

Sample php script

 $url = <applicable happyfox url>;
 $api_key = 
 $auth_code = 
 $input = array(
     "subject" => "Ignition issues with the millenium falcon",
     "text" => "Need to get this piece of junk flying",
     "category" => 1,
     "priority" => 1,
     "email" => "",
     "name" => "Han Solo",
     "t-cf-1" => "Chewie, we're home!",
     "t-cf-2" => array(
        1, 4, 5
 $data = json_encode($input);
 $headers = array(
 $ch = curl_init();
 $options = array(
     CURLOPT_URL => $url,
     CURLOPT_HEADER => true,
     CURLOPT_POST => 1,
     CURLOPT_HTTPHEADER => $headers,
     CURLOPT_USERPWD => $api_key . ":" . $auth_code
 curl_setopt_array($ch, $options);
 $result = curl_exec($ch);
 if (!curl_errno($ch)) {
     $info = curl_getinfo($ch);
     if ($info['http_code'] == 500) {
         echo "Damn! ERROR 500";
         echo var_dump($info);
     } else {
         echo 'Successful run';
         echo $result;
         echo json_decode($result, true);

In the above script, we have json-encoded the data that is being used for creating the ticket. Please ensure that when json-encoded data is used, the ContentType matches the type of input data i.e “Content-Type:application/json” in this case.

Also, “Additional Services” custom field is referred to by the internal field-name “t-cf-2”. Note that, the we are passing the lookup-ids to this array instead of the actual values.

On executing this script the following ticket gets created. On the ticket-detail page, we can see the proper display values for “Additional Services” field that we set via API.
