cURL + PHP - Attachments in Trello cards

Question

How are you?

Anybody who used the API for PHP Trello to send an attachment to a card can explain me better how it works?

I have an HTML page with some input type="text", select and input type="file" multiple

To send the data do trello API, I'm doing this way:

JAVASCRIPT

var files = document.getElementById('Trello attachment'). files;

var formData = new FormData();

for (i = 0; i <myFiles.length; i ++) {
  formData.append('file[]', myFiles[i]);
}
var ajax = new XMLHttpRequest();
ajax.open('POST', 'assets/php/ajaxResponse.php');
ajax.send(formData);

PHP ajaxResponse

if (! empty ($_ FILES)) {
  for ($i = 0; $i <count ($_FILES['file']['name']); $i++) {
    $chAttachment = curl_init();
    curl_setopt($chAttachment, CURLOPT_URL, 'https://api.trello.com/1/cards/tQxhxRJO/attachments?key=key&token=token');

    curl_setopt($chAttachment, CURLOPT_POSTFIELDS, http_build_query(
      variety(
        'name' => $_FILES ['file'] ['name'] [$i],
        'file' => $_FILES ['file'] ['tmp_name'] [$i]
      )
    ));

    curl_setopt($chAttachment, CURLOPT_RETURNTRANSFER, 1);
    $result = curl_exec ($chAttachment);
    curl_close($chAttachment);
    print_r($result);
  }
}

The problem i'm facing is, with the API i can create the attachments on the tQxhxRJO ID card, however, in trello they show the filename because by curl_setopt i set up the name i want through the name param, but all uploaded files have 14 bytes, this means it doesn't it uploads correctly, when I click to download or open the attachments on the trello card, i can download the file, but, all my files named Upload, if you open the file with VSCode i.e, the contentcontains the filename who i sent.

Does anyone know how to upload via cURL correctly?

Thank you so much!

Solved!

If anybody here need any help on how to upload the files using cURL in trello, here is the trick!

for($i = 0; $i < count($_FILES['file']['name']); $i++){
 $args = array(
   'file' => new CurlFile($_FILES['file']['tmp_name'][$i], $_FILES['file']['type'][$i],$_FILES['file']['name'][$i]),
   'key'   => 'mykey',
   'token' => 'mytoken',
   'mimeType' => $_FILES['file']['type'][$i],
   'name' => $_FILES['file']['name'][$i]
 );
        
 $chAttachments = curl_init();
 curl_setopt($chAttachments, CURLOPT_URL,'https://api.trello.com/1/cards/' . $jsonDecoded['shortLink'] . '/attachments/');
 curl_setopt($chAttachments, CURLOPT_POST,1);
 curl_setopt($chAttachments, CURLOPT_POSTFIELDS, $args);
 $resultAttachments = curl_exec($chAttachments);
 curl_close($chAttachments);
}
