<form method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
<label for="">Label</label>
<input type="file" name="" id="" />
</form>

The form method must be post and the enctype set as it is below. The hidden input for MAX_FILE_SIZE must also be included. The value is the max file size (in bytes?).
