android — загрузка файлов и строк на php сервер

Я хочу загрузить файлы и строки в HTML-форму на сервере PHP. Я загрузил файлы с кодом ниже, но я не знаю, как загрузить строку. Как мне изменить этот код для загрузки строк в текстовые поля формы?
Моя HTML-форма:

    <form name="form" id="gallery" method="post" enctype="multipart/form-data" action="send_1.php">
<div id="contain" >
<div class='file_browse_wrapper' id="file1">
<input type="file" size="32" name="file1" value=""  />
<input type="file" size="32" name="file2" value=""  />
<input type="text" size="32" name="phonenumber" value="1234" />
<input type="text" size="32" name="uploadmessage" value="some text" />
</div>
</div><br>
<input type="submit" name="add" id="add" value="click me" /><!--end add-->
</form><!--end form-->

Мне удалось загрузить файлы с этим кодом:

 public int uploadFiles(int pictureNumber, String strToUpload1, String strToUpload2) {
String uploadServerUri;
String uploadFilePath = Environment.getExternalStorageDirectory().toString() + "/Pictures/MyCameraApp/";
