这是我的index.php API
否则,如果($标记=='秩序'){

回声json_en code($响应);
}
index.php文件调用这个函数订单明细
公共职能订单明细($ UID,$ PID,$数量,$ totalprice,$ finalprice){
$presult =请求mysql_query(SELECT * FROM产品其中pid = $ PID);
$ PRODUCT_ID = $presult ['产品id'];
$最后=请求mysql_query(INSERT INTO vieworders(UID,产品ID,数量,$ totalprice,finalprice)
VALUES('$ UID','$产品id','$量,$ totalprice','$ finalprice'));
}
新的JSON响应。虽然我的产品也不会显示阵列。为什么JSON标签显示'我',而不是PID [I]?相同的数量和totalprice
10月4日至20日:19:31.615:E / ViewRootImpl(20740):sendUserActionEvent()MVIEW == NULL
10月4日至二十日:19:44.505:E / JSON(20740): {"tag":"order","success":0,"error":0,"successfullypost":1,"user":{"username":"zulanawi","finalprice":null,"pid":{"i":"0002"},"quantity":{"k":"3"},"totlaprice":{"l":"32.400000000000006"}}}{"success":0}

完成!谈到以后传递字符串数组PHP作为POST 我得到了答案。

I got the error when to parse the JSON. Error parsing data org.json.JSONException: End of input at character 0 of.

This is the code for calling a function in UserFunction class:
pTotalPrice=new double[cartSize]; // store array of totalprice
/** To be sent to DB **/
sPID = new String[cartSize];
sProduct = new String[cartSize];
sQuantity = new String[cartSize];
sTotalPrice = new String[cartSize];
if(cartSize >0)
{
for(int i=0;i<cartSize;i++)
{
final int counter = i;
// Get probuct data from product data arraylist
String pID = aController.getProducts(i).getProductId();
sPID[i] = pID;
String pName = aController.getProducts(i).getProductName();
sProduct[i] = pName;
double pPrice = aController.getProducts(i).getProductPrice();
int pQuantity = aController.getProducts(i).getProductQuantity();
sQuantity[i] = Integer.toString(pQuantity);
pTotalPrice[i] = pPrice * pQuantity;
sTotalPrice[i] = Double.toString(pTotalPrice[i]);
}
pFinalPrice -= pTotalPrice[counter];
sFinalPrice = Double.toString(pFinalPrice);
}
protected JSONObject doInBackground(String... args) {
UserFunctions userFunction = new UserFunctions();
JSONObject json = userFunction.orderDetails(username, sPID, sProduct, sQuantity, sTotalPrice, Double.toString(pFinalPrice));
Log.d("Button", "Order");
return json;
}
The function in UserFunction class
/**

**/
public JSONObject orderDetails(String username, String[] pid, String[] products, String[] quantity, String[] totalprice, String finalprice) {
// Building Parameters
List params = new ArrayList();
params.add(new BasicNameValuePair("tag", order_tag));

params.add(new BasicNameValuePair("totalprice[l]", totalprice[l]));
}
JSONObject json = jsonParser.getJSONFromUrl(orderURL,params);
return json;

The java parser class:

This is my index.php api
else if ($tag == 'order') {
$username = $_POST['username'];
$finalprice = $_POST['finalprice'];
$pid = $_POST['pid'];
$quantity = $_POST['quantity'];
$totalprice = $_POST['totalprice'];
$response["successfullypost"] = 1;
$response["user"]["username"] = $username;
$response["user"]["finalprice"] = $finalprice;
$response["user"]["pid"] = $pid;
$response["user"]["quantity"] = $quantity;
$response["user"]["totalprice"] = $totalprice;
echo json_encode($response);
$uResult = mysql_query("SELECT * FROM users WHERE username = $username");
$uid = $uResult['uid'];
$counter = sizeof($pid);
for ( $i=0; $i < $counter; $i++) {
$db-> orderdetails($uid, $pid[$i], $quantity[$i], $totalprice[$i], $finalprice);
}
}
else {
$response["error"] = 3;
$response["error_msg"] = "JSON ERROR";
echo json_encode($response);
}
index.php call this orderdetails function
public function orderdetails ($uid, $pid, $quantity, $totalprice, $finalprice) {
$pResult = mysql_query("SELECT * FROM products WHERE pid = $pid");
$Product_ID = $pResult['ProductID'];
$final = mysql_query("INSERT INTO vieworders (uid, ProductID, quantity, $totalprice, finalprice)
VALUES ('$uid', '$ProductID', '$quantity', '$totalprice', '$finalprice')");
}
The new JSON Response. although I have to products it don't show the array. why the JSON tag show 'i' instead of pid[i]? same for quantity and totalprice
04-20 10:19:31.615: E/ViewRootImpl(20740): sendUserActionEvent() mView == null

解决方案
DONE!!! After referring to Passing String array to PHP as POST I got the answer.
/**
* Function store order details
**/
public JSONObject orderDetails(String username, String[] pid, String[] products, String[] quantity, String[] totalprice, String finalprice) {
// Building Parameters
List params = new ArrayList();
params.add(new BasicNameValuePair("tag", order_tag));
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("finalpice", finalprice));
for (int i = 0; i < pid.length; i++) {
params.add(new BasicNameValuePair("pid[]", pid[i]));
}
for (int j = 0; j < products.length; j++) {
params.add(new BasicNameValuePair("products[]", products[j]));
}
for (int k = 0; k < quantity.length; k++) {
params.add(new BasicNameValuePair("quantity[]", quantity[k]));
}
for (int l = 0; l < totalprice.length; l++) {
params.add(new BasicNameValuePair("totalprice[]", totalprice[l]));
}

return json;
