Problem

File not being uploaded on server through PHP – cURL

Solution

The CURLFile interface must be used to upload files.

Code

<?php

$url = 'http://192.168.1.94:5000/api/v1/upload-picture';

$img = 'img/placeholder.png';

// Form-data
$data_array = array(
 'id' => 1,
 'picture_type' => 'user',
 'file' => new CurlFile($img)
 );

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_array);
curl_setopt($curl, CURLOPT_SAFE_UPLOAD, false);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
 echo "cURL Error #:" . $err;
} else {
 echo $response;
}

Please update if any better alternative.
