        dialog.dismiss();
        return serverResponseCode;

    } // End else block
}

}

这里是 php：

<?php

$file_path = "uploads/";

$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
    echo "success";
} else{
    echo "fail";
}

?>
