Witam, napisałem skrypt:

[PHP] pobierz, plaintext 
if (isset($_FILES['file']['name'])) {
            $file_name = $_FILES['file']['name'];
            $target_file = "../uploads/dir/".$file_name;
            $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
            $tmp_name = $_FILES['file']['tmp_name'];
            if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
                echo "bad_extension";
            } else {
                print_r($_FILES['file']); die;
                $time = time();
                $file_up_name = $time . $file_name;
                move_uploaded_file($tmp_name, "/" . $file_up_name);
                createThumbnail($engine->domain . "/uploads/dir/" . $file_up_name, "../uploads/dir/250x250_" . $file_up_name, 250, 250);
                createThumbnail($engine->domain . "/uploads/dir/" . $file_up_name, "../uploads/dir/250_" . $file_up_name, 250);
                createThumbnail($engine->domain . "/uploads/dir/" . $file_up_name, "../uploads/dir/500x500_" . $file_up_name, 500, 500);
                createThumbnail($engine->domain . "/uploads/dir/" . $file_up_name, "../uploads/dir/500_" . $file_up_name, 500);
                echo $engine->domain . "/uploads/dir/250_" . $file_up_name;
            }
        } else {
            echo "no_file";
        }
[PHP] pobierz, plaintext 

i nie wrzuca mi to pliku, a print_r($_FILES['file']) zwraca wynik:


nie wiem dlaczego?

Formularz wygląda tak:

[HTML] pobierz, plaintext 
<form action="upload-file" enctype="multipart/form-data" method="post">
                                <div class="custom-file">
                                    <input type="file" class="custom-file-input custom-file-input-image"  id="5_slika_upload_{$id}" name="file" accept="image/*">
                                    <label class="custom-file-label" id="name-image-{$id}"  for="customFile">Nie wybrano pliku</label>
                                </div>
 
                                <button id="upload_{$id}" style="margin-top: 20px;" class="btn btn-primary" type="submit">Wyślij</button>
 
                                <button class="btn btn-primary trigger--fire-modal-5" style="display:none;" id="modal-image-{$id}" data-id="{$id}">pokaż modal</button>
                            </form>
[HTML] pobierz, plaintext 

nie wiem co się zepsuło... wcześniej działało

@edit:
Upload max filesize był ustawiony w php.ini na 2 MB... zmiana na 4 mb sprawiła że zaczął upload działać
