PHP Curl not posting data, although it is receiving

I'm trying to make an API through PHP cURL and my client side (form submission) is receiving data from the API. It is just not posting it to the API.

$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type= application/json"));
curl_setopt($ch, CURLOPT_POST, true);

// execute the request and store the return value.
$message = curl_exec($ch);

echo 'Message returned from API is:' .  $message;

This is the code to receive the message from the API. It is returning a message so hopefully no errors there.

This is the API code (below):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>The API</title>
</head>

<body>
<?php

//date, job number, customer, worksite, duties performed, total hours spent, type of hours

$date = $_POST['date'];
$jobnumber = $_POST['jobnumber'];
$customer = $_POST['customer'];
$worksite = $_POST['worksite'];
$duties = $_POST['duties'];
$hours = $_POST['hours'];
$hourtype = $_POST['hourtype'];
$username = $_POST['username'];



$ok = true;
$error ;

//validate the inputs
if (empty($date)) {
    $ok = false;
    $error .= "Date field empty, ";
}

if (empty($jobnumber)) {
    $ok = false;
    $error .= "Job Number field empty, ";
}
if (empty($customer)) {
    $ok = false;
    $error .= "Customer field empty, ";
}

if (empty($worksite)) {
    $ok = false;
    $error .= "Worksite field empty, ";
}
if (empty($duties)) {
    $ok = false;
    $error .= "Duties field empty, ";
}
if (empty($hours)) {
    $ok = false;
    $error .= "Hours field empty, ";
}

if (empty($hourtype)) {
    $ok = false;
    $error .= "Hour type not specified, ";
}

$data = $date . ', ' . $jobnumber . ', ' . $customer . ', ' . $worksite . ', ' . $duties . ', ' . $hours . ', ' . $hourtype;
echo $data;
?>
</body>

</html>

My submit page is returning:

"Message returned from API is: , , , , , ,"

What am I doing wrong?

Stupid me somehow had this for the curl job:

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    ...
));

See the arbitrary Content-Type header that I set for the POST, which is obviously not right. It's preventing curl to set the right Content-Type which should be application/x-www-form-urlencoded.

Removed 'Content-Type: application/json' and the destination URL was successfully receiving the POST data.

You seem to be passing in an array to cURL.

$data = array( 'date' => $date, 'jobnumber' => $jobnumber, 'customer' => $customer, 'worksite' => $worksite, 'duties' => $duties, 'hours' => $hours, 'hourtype' => $hourtype, 'username' => $username );

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Instead, build a query string for cURL to work with like this:

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

The reason is because if you pass in an array, the Content-type header is automatically set to multipart/form-data, but you want application/x-www-form-urlencoded so you can access the POSTed information through the global $_POST.
