cURL PHP Newbie Needs a hand - php

Question

I am completely new to cURL requests in PHP.
I have an API that gives me the info below and wants me to send a POST request via cURL. I've tried some basic cURL examples but have no idea what how the additional data should be sent.
API Docs contain the following:
curl https://api.23andme.com/token/
-d client_id=xxx \
-d client_secret=yyy \
-d grant_type=authorization_code \
-d code=zzz \
-d "redirect_uri=https://localhost:5000/receive_code/"
-d "scope=basic%20rs3094315"
Here is my example code:
$data = array(
"client_id" => $client_id,
"client_secret" => $client_secret,
"grant_type" => "authorization_code",
"code" => $code,
"redirect_uri" => "http://localhost/23andme/",
"scope" => "basic"
);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch); //Uncomment to make it live again
if (!$response)
{
return false;
}
echo json_decode($response);

Answer 1

You could try
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
With your data array will send that as POST data since you already have curl_setopt($ch, CURLOPT_POST, true);.
http://php.net/manual/en/function.curl-setopt.php
So
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

You just missed two things in your code, here is a complete example using your code as base:
<?php
/* you must define an URL to POST to */
$url = "";
$data = array(
"client_id" => $client_id,
"client_secret" => $client_secret,
"grant_type" => "authorization_code",
"code" => $code,
"redirect_uri" => "http://localhost:8080/nope",
"scope" => "basic"
);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true)
/* this line below was missing in your code */;
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
$response = curl_exec($ch);
if (!$response)
{
echo 'A error has occurred ' . curl_error($ch);
return false;
}
echo json_decode($response);
?>
Try and adjust to your needs.
