[SOLVED] Sending JSON Post Request using CURL on Form Submit PHP

Issue

I have this function where I enroll a token to make a transaction process without the need to key-in of credentials.

Some blogs stated that curl exec does the job in executing the curl, but nothing is happening with this function. can I somehow trigger this CURL using submit button in form? also, how can I know the errors of CURL?

$curl = curl_init();

                curl_setopt_array($curl, array(
                  CURLOPT_URL => 'url here',
                  CURLOPT_RETURNTRANSFER => true,
                  CURLOPT_ENCODING => '',
                  CURLOPT_MAXREDIRS => 10,
                  CURLOPT_TIMEOUT => 0,
                  CURLOPT_FOLLOWLOCATION => true,
                  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
                  CURLOPT_CUSTOMREQUEST => 'POST',
                  CURLOPT_POSTFIELDS =>'{
                    "clientIp": $_clientip,

                  CURLOPT_HTTPHEADER => array(
                    'Content-Type: application/json',

                  ),
                ));

                $response = curl_exec($curl);

                curl_close($curl);
                echo $response;

Solution

you can try it via defining the body as structured representation and then transform it to JSON:

$recipient['dst']      = "+000000";
$message['recipients'] = array($recipient);
$message['text']       = "this is a test message";
$job['messages']       = array($message);

$json = json_encode($job);

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'url here',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => $json,
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json',
    'Idempotency-Key: HMCENRO202001140009T',
    'Authorization: Basic Og=='
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;
