Is it supposed to? My code:
if ($_POST && $_FILES) {
$tmp_name = $_FILES['file']['tmp_name'];
$item = $_FILES['file'];
$uploads = wp_upload_dir();
if (is_writable($uploads['path'])) {
if (!empty($tmp_name)) {
if ($tmp_name) {
$overrides = array('test_form' => false);
$file = wp_handle_upload($item, $overrides);
}
}
}
}
