Updating row in database from android app - php

I'm trying to update a row in my database via my android app. My pulling from the database is working but I'm having trouble with the updating. My code for updating is as follows:
My AsyncTask class:
private class UpdateAnimalTask extends AsyncTask<Void, Void, Boolean>
{
#Override
protected Boolean doInBackground(Void... arg0)
{
try
{
ID = (EditText) findViewById(R.id.eTid);
Name = (EditText) findViewById(R.id.eTname);
Type = (EditText) findViewById(R.id.eTtype);
Breed = (EditText) findViewById(R.id.eTbreed);
Gender = (EditText) findViewById(R.id.eTgender);
Injuries = (EditText) findViewById(R.id.eTinjuries);
Treat = (EditText) findViewById(R.id.eTtreat);
String nM = Name.getText().toString();
String tP = Type.getText().toString();
String bR = Breed.getText().toString();
String gE = Gender.getText().toString();
String iN = Injuries.getText().toString();
String tR = Treat.getText().toString();
ArrayList<NameValuePair> up = new ArrayList<NameValuePair>();
up.add(new BasicNameValuePair("name", nM));
up.add(new BasicNameValuePair("type", tP));
up.add(new BasicNameValuePair("breed", bR));
up.add(new BasicNameValuePair("gender", gE));
up.add(new BasicNameValuePair("injuries", iN));
up.add(new BasicNameValuePair("treatment", tR));
String phpLink = "http://select.garethprice.co.za/update.php?name=" + nM;
Log.e("Test", up.toString());
dbUpdate(up, phpLink);
Log.e("Test", up.toString());
}
catch(Exception e)
{
Log.e("log_tag", "Error in uploading " + e.toString());
Toast.makeText(getBaseContext(), "Error " + e.toString(), Toast.LENGTH_LONG).show();
return false;
}
return true;
}
#Override
protected void onPostExecute(Boolean result)
{
if(result)
{
Toast.makeText(getBaseContext(), "Successfully updated", Toast.LENGTH_LONG).show();
}
}
}
My dbUpdate method which is being called inside my asynctask class:
public void dbUpdate(ArrayList<NameValuePair> data, String phpL)
{
InputStream iS = null;
try
{
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(phpL);
httppost.setEntity(new UrlEncodedFormEntity(data));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
iS = entity.getContent();
}
catch(Exception e)
{
Log.e("log_tag", "Error in http connection " + e.toString());
Toast.makeText(getBaseContext(), "Error " + e.toString(), Toast.LENGTH_LONG).show();
}
}
My php:
<?php
include_once 'db.php';
$con=mysql_connect(DB_HOST, DB_USER, DB_PASSWORD)or die("cannot connect");
mysql_select_db(DB_DATABASE)or die("cannot select DB");
$nM = $_GET['name'];
$tP = $_POST['type'];
$bR = $_POST['breed'];
$gE = $_POST['gender'];
$iN = $_POST['injuries'];
$tR = $_POST['treatment'];
$sql = "UPDATE tbl_Animals SET animal_Type = '$tP', animal_Breed = '$bR', animal_Gender = '$gE', animal_Injuries = '$iN', animal_Treatments = '$tR' WHERE animal_Name = '$nM'";
echo "test: " . $nM . $tP . $bR . $gE . $iN . $tR;
mysql_query($sql,$con) or die("error: " . mysql_error());
mysql_close($con)
?>
Executing the asynctask in my update button:
public void Update(View v)
{
new UpdateAnimalTask().execute();
}
The android code is not breaking so I suspect it's something with the php because my toast pops up that says update successful in my onPostExecute.
Thank you in advance.

insert values to mysql using php

I am inserting some values from my android login page to mysql database using php .
login.php
<?php
$con = mysql_connect("localhost","abc","xyz") or die(mysql_error());
mysql_select_db("sync",$con) or die(mysql_error());
$user_name = $_POST['user_name'];
$user_mobile_no = $_POST['user_mobile_no'];
$user_email_id = $_POST['user_email_id'];
$imei_no = $_POST['imei_no'];
$login_date = $_POST['login_date'];
$time = $_POST['time'];
$user_name = 'Navdeep';
$user_mobile_no = '12345678990';
$user_email_id = 'nav#gmail.com';
$imei_no = '1234567890';
$login_date = '24-12-2012';
$time = '01:01:01';
$result = mysql_query("INSERT INTO
login_details(user_name,user_mobile_no,user_email_id,
imei_no,login_date,time)
VALUES('$user_name','$user_mobile_no','$user_email_id',' $imei_no','$login_date','$time')");
if($result)
{
$response["success"] = 1;

echo json_encode($response);
} else {
$response["success"] = 0;
$response["message"] = "There was an error inserting user details";
echo json_encode($response);
}
mysql_close($con);
?>
When i use $_POST[''] values are getting inserted as blank , but when i hardcode the values it is getting inserted , need some help
Android code :
try{
JSONObject jsonObject = new JSONObject();
jsonObject.put("user_name",userName);
jsonObject.put("user_mobile_no",mobNo);
jsonObject.put("user_email_id",email);
jsonObject.put("imei_no",imeino);
jsonObject.put("login_date",date);
jsonObject.put("time",time);
JSONArray jsonArray = new JSONArray();
jsonArray.put(jsonObject);
String basicAuth = "Device " + new
String(Base64.encode((imeino).getBytes(), Base64.NO_WRAP));
RequestBody body =
RequestBody.create(JSON,String.valueOf(jsonArray));
OkHttpClient okHttpClient = new OkHttpClient();
Request request = new Request.Builder().header("Authorization",
basicAuth).url(url).post(body).build();
Call call = okHttpClient.newCall(request);
call.enqueue(new Callback() {
#Override
public void onFailure(Call call, IOException e) {
e.printStackTrace();
Login.this.runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getBaseContext(), "Request to the
server failed", Toast.LENGTH_SHORT).show();
}
});
}
#Override
public void onResponse(Call call, Response response) throws
IOException {
Log.i("response ", "onResponse(): " + response );
StatusLine statusLine = null;
String result = response.body().string();
if(result.equals("") || result.equals(null)){
Log.i("No response", "No response");
}else{
Log.i("Response","Response "+result);
statusLine = StatusLine.get(response);
final int responseCode = statusLine.code;
Log.d("Code:", String.valueOf(responseCode));
}
}
});
}catch (Exception e){
e.printStackTrace();
}
You should send form data request from android.
Replace this
JSONObject jsonObject = new JSONObject();
jsonObject.put("user_name",userName);
jsonObject.put("user_mobile_no",mobNo);
jsonObject.put("user_email_id",email);
jsonObject.put("imei_no",imeino);
jsonObject.put("login_date",date);
jsonObject.put("time",time);
JSONArray jsonArray = new JSONArray();
jsonArray.put(jsonObject);
String basicAuth = "Device " + new
String(Base64.encode((imeino).getBytes(), Base64.NO_WRAP));
RequestBody body =
RequestBody.create(JSON,String.valueOf(jsonArray));
OkHttpClient okHttpClient = new OkHttpClient();
Request request = new Request.Builder().header("Authorization",
basicAuth).url(url).post(body).build();
With
RequestBody formBody = new FormBody.Builder()
.add("user_name",userName)
.add("user_mobile_no",mobNo)
.add("user_email_id",email)
.add("imei_no",imeino)
.add("login_date",date)
.add("time",time)
.build();
String basicAuth = "Device " + new
String(Base64.encode((imeino).getBytes(), Base64.NO_WRAP));
Request request = new Request.Builder().header("Authorization",
basicAuth).url(url).post(formBody).build();

POST string with keys and values in android to php

i want to send all contacts with contact name and number in one row in one array in my android application like
john => "+92312xxxxxxx" ,
Right now i'm using namevaluepairs to post two arrays but it's not working like :
public class ContactList extends Activity {
public TextView outputText;
String phoneNumber = null;
String names = null;
String[] keyValue;
String[] kes;
int Count;
String s = "";
#Override

outputText = (TextView) findViewById(R.id.textView1);
fetchContacts();
//Http connection
InputStream is=null;
List<NameValuePair> nameValuePairs =new ArrayList<NameValuePair>(1);
for (int i = 0; i < Count ; i++)
{
nameValuePairs.add(new BasicNameValuePair("CN[]", keyValue[i]));
nameValuePairs.add(new BasicNameValuePair("names[]",kes[i]));
Log.i("Response", "you sent :" +kes[i]+" :"+ keyValue[i] + "\n ");
}
try{
HttpClient httpclient = new DefaultHttpClient();

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}
catch(ClientProtocolException e)

Log.e("ClientProtocol","Log_tag");
e.printStackTrace();
System.out.println("Excep: "+e);
}
catch(IOException e)
{
Log.e("Log_tag","IOException");

}
String result = "";
try

StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");

Log.i("List","24th"+keyValue[23]);
Toast.makeText(getApplicationContext(), "99th "+keyValue[909] ,Toast.LENGTH_LONG).show();
}
PHP after receiving contacts will match them and return only those which have a match with database contacts. And then it returns contacts with names
i'm stuck with sending and receving part
Here is php code
<?php
define('DB_HOST', 'localhost');
define('DB_NAME', 'verification');
define('DB_USER','root');
define('DB_PASSWORD','');
// 1. Create a database connection
$connection = mysqli_connect(DB_HOST,DB_USER,DB_PASSWORD);
if (!$connection) {
die("Database connection failed: " . mysqli_error());
}
// 2. Select a database to use
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
die("Database selection failed: " . mysqli_error());
}
$PhoneNum= $_POST["CN"];
$i=0;
$j=0;
$friends = array();
$Invite = array();
unset ($PhoneNum[0]);
foreach ($PhoneNum as $i=> $element){
//or do whatever you need to do to that variable
$query="SELECT Number FROM `user` WHERE Number=$element";
$query_exec = mysqli_query($connection ,$query);
if (!$query_exec)
{ echo mysql_error(); }
ELSE {
if(mysqli_num_rows($query_exec)>0)
{
$friends["$j"]= $PhoneNum[$i];
$j++;
}
else
{
;
}}
}
echo (json_encode($friends));
?>
You'll get a URL now that would look like:
www.example.com/yourscript?CN[]=keyValue1&names[]=key1&CN[]=keyValue2&names[]=key2 etc.. going on untill your whole list has looped.
I doubt that is what your PHP script wants to receive, you probably want to send the POST for each time you increment the loop. But thats just conjecture untill you post more information/code.
Instead send a JSON array as the value of the nameValuePair and convert it to a PHP array using json_decode function in the server side.

communicate with web database with android

I have a signup form in a android app which consist of a username and a password. I want that when a user click the submit button of the signup form then the username and password will be saved into a web-database(mySql database).
When a user press submit button then sendPostRequest(givenUsername, givenPassword); is executed.
and sendPostRequest() function is like that
private void sendPostRequest(String givenUsername, String givenPassword) {
class SendPostReqAsyncTask extends AsyncTask<String, Void, String>{
#Override
protected String doInBackground(String... params) {
String paramUsername = params[0];
String paramPassword = params[1];
System.out.println("*** doInBackground ** paramUsername " + paramUsername + " paramPassword :" + paramPassword);
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://10.0.2.2/imon.php");
BasicNameValuePair usernameBasicNameValuePair = new BasicNameValuePair("paramUsername", paramUsername);
BasicNameValuePair passwordBasicNameValuePAir = new BasicNameValuePair("paramPassword", paramPassword);
List<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>();
nameValuePairList.add(usernameBasicNameValuePair);
nameValuePairList.add(passwordBasicNameValuePAir);
try {
UrlEncodedFormEntity urlEncodedFormEntity = new UrlEncodedFormEntity(nameValuePairList);
httpPost.setEntity(urlEncodedFormEntity);
try {
HttpResponse httpResponse = httpClient.execute(httpPost);
InputStream inputStream = httpResponse.getEntity().getContent();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
StringBuilder stringBuilder = new StringBuilder();
String bufferedStrChunk = null;
while((bufferedStrChunk = bufferedReader.readLine()) != null){
stringBuilder.append(bufferedStrChunk);
}
return stringBuilder.toString();
} catch (ClientProtocolException cpe) {
System.out.println("First Exception caz of HttpResponese :" + cpe);
cpe.printStackTrace();
} catch (IOException ioe) {
System.out.println("Second Exception caz of HttpResponse :" + ioe);
ioe.printStackTrace();
}
} catch (UnsupportedEncodingException uee) {
System.out.println("An Exception given because of UrlEncodedFormEntity argument :" + uee);
uee.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result.equals("working")){
Toast.makeText(getApplicationContext(), "HTTP POST is working...", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Invalid POST req...", Toast.LENGTH_LONG).show();
}
}
}
SendPostReqAsyncTask sendPostReqAsyncTask = new SendPostReqAsyncTask();
sendPostReqAsyncTask.execute(givenUsername, givenPassword);
}
And my imon.php is like that:
<?php
$varUsername = $_POST['paramUsername'];
$varPassword = $_POST['paramPassword'];
if($varUsername != "" && $varPassword != ""){
$con = mysql_connect('localhost', 'root', '');
if (!$con) {
die('Not connected : ' . mysql_error());
}
// make foo the current db
$db_selected = mysql_select_db('post_db', $con);
if (!$db_selected) {
die ('Can\'t use foo : ' . mysql_error());
}
$sql="INSERT INTO post_table (username,password)
VALUES
('$varUsername ','$varPassword')";
if (!mysql_query($con,$sql))
{
die('Error: ' . mysql_error($con));
}
echo 'working';
}else
{
echo 'invalid';
}
?>
But data is not inserted into my-sql database.
What am i wrong here??
What should i do to insert the data of signup form into web database??
You can't do this
mysql_connect('localhost', 'root', '');
and then do this
if (!mysqli_query($con,$sql))
mysql and mysqli are separate extensions. you can't share resources from one with another.
mysqli_query() and mysql_query() doesn't take the same param order. the first param of mysql_query() is the query. where in mysqli_query first parameter is the connection resource. You were also intermixing the connections earlier as well.

Geting data from a remote database Android

I'm making an Android app and I'm trying to retrieve data from a remote database.
My question is how can I check if the query result contains data and is not empty?
I'm using JSON but I'm new to it. Here is my code:
public class MainActivity extends Activity {
private TextView txt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout rootLayout = new LinearLayout(getApplicationContext());
txt = new TextView(getApplicationContext());
rootLayout.addView(txt);
setContentView(rootLayout);
txt.setText("Connexion...");
txt.setText(getServerData(strURL));
}
public static final String strURL = "http://.../marecherche/adresse.php";
private String getServerData(String returnString) {
InputStream is = null;
String result = "";
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("adresse","adr casa"));
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(strURL);
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection " + e.toString());
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result " + e.toString());
}
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.i("log_tag","raison sociale: "+json_data.getString("raison_social")+
", Adresse: "+json_data.getString("adresse")
);
returnString += "\n\t" + jArray.getJSONObject(i);
}
}catch(JSONException e){
Log.e("log_tag", "Error parsing data " + e.toString());
}
return returnString;
}
}
and the php file:
<?php
mysql_connect("localhost", "root", "passwd");
mysql_select_db("dbname");
$mots = explode(' ', $_REQUEST['adresse']);
$like = array();
foreach ($mots AS $mot) {
$like[] = ' "%' . mysql_real_escape_string($mot) . '%" ';
}
$condition = implode(' OR adresse LIKE ', $like);
$sql = mysql_query("SELECT * FROM entreprise WHERE adresse like " . $condition);
while ($row = mysql_fetch_assoc($sql))
$output[] = $row;
print(json_encode($output));
mysql_close();
?>
You could just create your own return to check for, something like:
PHP file:
if (is_array($output)) {
print(json_encode($output));
} else
echo "empty";
}
Java:
if (result.equals("empty")) {
return;
}
JSONArray jArray = new JSONArray(result);
// etc
My question is how can I check if the query result contains data and
is not empty?
=> Check result string is null or not before creating JSONArray.
