Sending an image to aws via php - php

Question

The main problem that i've to do is sending an image from another server to AWS after some process. For that i've done the database processes in the first server. It works very well, i tested it. After that i've to send this image directly to AWS to start another .php file. I try it via cURL function:
server1.php the php file that's found in the first server:
$url = 'http://myawsurl.com/server/test.php';
$imageData = file_get_contents($_FILES['fileToUpload']['tmp_name']);
$post_data = array(
'tmp' => $_FILES["fileToUpload"]["tmp_name"],
'type' => $_FILES["fileToUpload"]["type"],
'name' => $_FILES["fileToUpload"]["name"],
'data' => $imageData
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
$output = curl_exec($ch);
curl_close($ch);
print_r($output);
test.php the php file that's found in aws:
if ($_POST["tmp"] && $_POST["name"] && $_POST["type"] && $_POST["data"]) {
$target_dir_requests = "/requests/";
create_folder_if_not_exist(ABSPATH . $target_dir_requests);
$dir_for_req_server = ABSPATH . $target_dir_requests . basename($_FILES["fileToUpload"]["name"]);
$dir_for_req_server = base64_to_jpeg($_POST["data"],$dir_for_req_server);
// After some requests that i've to do and i've done
} else {
echo "data sending error";
}
i tried something for todo but they did not work. Could you please help me for find a solution ? Thanks.

You are checking if the variable is true or not with the if($_POST[])
What you actually want is to check if the variable isset
Try this and see if you get any result:
if(isset($_POST['tmp'])){
echo 'test';
}
Or
$tmp = isset($_POST['tmp']) ? trim($_POST['tmp']) : null;
if(!empty($tmp)){
echo 'test';
}
The curl itself should be working
