Is there a way to send data like the title said?
I know how to send data from TextView or EditText, I just have to insert a single data to the server, but to send data from JsonArray that has multiple data? I don't know how to make it work.
I created a JsonArray with this code in button.onClick and set it to TextView so I know the output of JsonArray:
int size = adapter3.getCount();
StringBuilder b = new StringBuilder();
JSONArray jArray = new JSONArray();
for (int i=0;i<=size;i++){
jArray.put(adapter3.getItem(i).getJsonObject());
}
b.append(jArray);
TextView Star = (TextView)findViewById(R.id.test);
Star.setText(b.toString());
Then the output seems like:
[{"id":"1","nilai":"1"},{"id":"2","nilai":"1"},{"id":"3","nilai":"1"},{"id":"4","nilai":"1"},{"id":"5","nilai":"1"}]
Now I don't know how to send this JsonArray to MySQL through PHP, so I need help here.

To send post request use volley library :
compile 'dev.dworks.libs:volleyplus:+'
googling for use that library, this my code to send multiple post data
String url = "url that handle the request";
final Context currentContext = CompleteDataActivity.this;
final StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// success handling code here
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error handling code here
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> param = new HashMap<>();
//Post parameter
param.put("parameter1", jsonstring1);
param.put("parameter2", jsonstring2);
return param;
}
};
H.showLoadingDialog(currentContext);
MyVolley.getRequestQueue().add(request);
BTW, orang indo ya?
you want to send something like that [{"id":"1","nilai":"1"},{"id":"2","nilai":"1"},{"id":"3","nilai":"1"},{"id":"4","nilai":"1"},{"id":"5","nilai":"1"}]
what you can do is :
Java/Android
String jsonObjectString="{\"id\":1,\"nilai\":1}";
you can use a loop to make as much as you want:
ArrayList<String> yourList=new Arrayist<>();
for(int i=0;i<5;i++)
{
yourList.add("{\"id\":"+(i+1)+",\"nilai\":1}");
}
then use Volley to send the ArrayList with POST:
String url = "url that handle the request";
final Context currentContext = CompleteDataActivity.this;
final StringRequest request = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// success handling code here
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error handling code here
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> param = new HashMap<>();
//Post parameter
for(int i=0;i<yourList.size();i++)
{
param.put("jsonObject"+i, yourList.get(i));
}
return param;
}
};
H.showLoadingDialog(currentContext);
MyVolley.getRequestQueue().add(request);
use this code to get your list of JSONObject for .php
for($i=0;$i<5;$i++)
{
$var = "jsonObject".$i;
$jsonObject=json_decode($_POST[$var]);
$id = $jsonEtape->{'id'};
$nilai = $jsonEtape->{'nilai'};
$sql = "your query;";
mysqli_query($con,$sql);
}
hope this helps
