ajax download of images

[Avante]

Help me find a mistake in the processors of the incoming servers.

Server doesn't bring anything back when it's worth checking. isset( $_FILES['files'] ), but if put isset( $_FILES )he's starting to bring something back.

Form:

<input title="Выберите файл для загрузки" id="upload_media" type="file" name="files" accept=".txt,image/*">

Processor:

$('input[type=file]').change(function(){
    Upload.files = this.files[0];
    var upload = Upload.upload();
});
var Upload = {

files: 0,

upload: function() {
var data = new FormData();
$.each( Upload.files, function( key, value ){
    data.append( key, value );
});

$.ajax({
    url: "upload.php",
    type: "POST",
    data: data,
    contentType: false,
    cache: false,
    processData:false,
    success: function( reply ){
        alert( "test. " + reply );
    },
    error: function( reply ){
        console.log('ОШИБКИ AJAX запроса: ' + reply.responseText );
    }
});

},

}

Server:

if ( isset( $_FILES['files'] ) ) {

$error = false;

$status = false;

$files = [];

$uploaddir = './uploads/';
$files = $_FILES;
$uploadfile = $uploaddir . basename($files['name']);

if (move_uploaded_file( $files['tmp_name'], $uploadfile) ) {
    echo "Файл загружен";
} else {
    echo "Ошибка";
}

echo json_encode( $files['name'] );

}

isset( $_FILES['files']) It doesn't work as far as I know.

See if you can condition this:

if ($_FILES['files']['error'] === UPLOAD_ERR_OK and $_FILES['files']['size'] != 0) {
    // загрузка прошла успешно
}else{
    // загрузка не удалась
}
