دریافت از $_REQUEST

دقیقآ نمیشه فهمید مشکل از کجاست و کدهات هم مشکلی نداره

این کد رو جایگزین اون قسمتی که گفتی مشکل داره کن:

  $word   = '%'.mysqli_real_escape_string($connection,$word).'%';
  $result = mysqli_query($connection,"SELECT * FROM news WHERE news_title like '$word' ");

    public static String url = "http://192.168.1.4/learneng2/service.php?action=";


 G.params.add(new BasicNameValuePair("user_id", G.cellcode));
                G.params.add(new BasicNameValuePair("word_s", input));
                Commands.search(G.params);

    public static void search(ArrayList<NameValuePair> params) {
        G.getJsonString = Webservice.readUrl(url + "search", params);
    }

کد کامل سمت آندروید رو نوشتم
