Send Json String using volley to php and decode it - php

Question

I know how to send data using volley library and get those from php. Problem is, I want to send a Json String and decode those data from the php side.
This is the method I am using to send data using param. Last item is the json String
private void checkOrderNo() {
pDialog.setMessage("Sending...");
showDialog();
DateFormat df = new SimpleDateFormat("yyyy/MM/dd hh:mm:ss");
final String nowDate = df.format(new Date());
//final day of the month
Date today = new Date();
Calendar calendar = Calendar.getInstance();
calendar.setTime(today);
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY_OF_MONTH, 1);
calendar.add(Calendar.DATE, -1);
Date lastDayOfMonth = calendar.getTime();
DateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
final String lastDate = sdf.format(lastDayOfMonth);
Log.d("Last day ", sdf.format(lastDayOfMonth) + " // Today" + nowDate);
// Tag used to cancel the insert
String tag_string_req = "req_insert";
final StringRequest strReq = new StringRequest(Request.Method.POST,
AppConfig.URL_ITEM_DETAILS_SEND, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
hideDialog();
try {
JSONObject jObj = new JSONObject(response);
if (jObj.names().get(0).equals("found")) {
newOrderId = jObj.getString("found").toString();
orderIdForItemTable = newOrderId;
Log.d(TAG, "newOrderId: " + newOrderId);
Log.d(TAG, "New repID 2 inserted into sqlite: " + newOrderId + " " + nowDate);
sqLiteHandler.addItemDetails(newOrderId, repID, dealerID, nowDate, lastDate, selectedDisChannel);
finish();
Bundle basket = new Bundle();
basket.putString("dealerName", dealerName);
basket.putString("orderNo", newOrderId);
basket.putString("jsonString", json_string);
Intent intent = new Intent(SelectItem.this, ItemCart.class);
intent.putExtras(basket);
startActivity(intent);
finish();
} else {
Toast.makeText(getApplicationContext(), "Invalied Request", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Inserting Error: " + error.getMessage());
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
// Posting params to register url
Map<String, String> params = new HashMap<String, String>();
params.put("order_no", orderId);
params.put("repID", repID);
params.put("dealerID", dealerID);
params.put("nowDate", nowDate);
params.put("lastDate", lastDate);
params.put("disChannel", selectedDisChannel);
params.put("jsonString", json_string);
return params;
}
};
strReq.setRetryPolicy(new DefaultRetryPolicy(15000, 1,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}
This is my PhP for volley
<?php
require_once 'include/Config_test.php';
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die("connection failed");
mysql_select_db(DB_DATABASE,$con) or die("db selection failed");
$order_no = $repID = $dealerID = $nowDate = $jsonString = $lastDate = $disChannel = "";
if(isset($_POST['order_no'])){
$order_no = $_POST['order_no'];
$repID = $_POST['repID'];
$dealerID = $_POST['dealerID'];
$nowDate = $_POST['nowDate'];
$lastDate = $_POST['lastDate'];
$disChannel = $_POST['disChannel'];
$jsonString= $_POST['jsonString'];
}
$result = mysql_query("SELECT MAX(order_no) FROM tbl_items_header_t");
$row = mysql_fetch_row($result);
if($row[0] < 70000000){
$highest_id = 70000000;
} else{
$highest_id = $row[0] + '1';
}
//$highest_id = $row[0] + '1';
$query = mysql_query("INSERT INTO tbl_items_header_t(order_no,rep_no,dealer_no,order_date,last_date,dis_channel,status)
VALUES('$highest_id','$repID','$dealerID','$nowDate','$lastDate','$disChannel','')");
$json['found']= $highest_id;
echo json_encode($json);
?>
I know send json String using DefaultHttpClient but it is deprecated. I have to use two PHP also. I want to do it using volley.
This is what I use for get json String using DefaultHttpClient. It worked. But I want to use this in the volley.
<?php
require_once 'include/Config_test.php';
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die("connection failed");
mysql_select_db(DB_DATABASE,$con) or die("db selection failed");
$postdata = file_get_contents('php://input');
$data = json_decode($postdata, true);
if (is_array($data['sending_items'])) {
foreach ($data['sending_items'] as $record) {
$order_no = $record['order_no'];
$items = $record['items'];
$items_no = $record['items_no'];
$plant = $record['plant'];
$quantity = $record['quantity'];
mysql_query("INSERT INTO tbl_item_list(order_no, items, items_no, plant, quantity) VALUES('$order_no', '$items', '$items_no', '$plant', '$quantity')");
}
}
echo json_encode($data);
mysql_close($con);
?>
