I have a simple registration script, but android studio isnt properly putting data into the php script. I ran the php script on a browser, and it puts data in just fine, but android studio isnt doing it right.

Here is the registerrequest script.

public class RegisterRequest extends StringRequest {



    private static final String REGISTER_REQUEST_URL = "http://192.168.*.*:80/phptesting/Register.php";

    private Map<String, String> params;

    public RegisterRequest(String username, String password,String isAdmin,

                           Response.Listener<String> listener,

                           Response.ErrorListener errListener){

        super(Method.POST, REGISTER_REQUEST_URL,listener,errListener);

        params = new HashMap<>();

        params.put("username",username);

        params.put("password",password);

        params.put("isAdmin",isAdmin+"");

    }



    public Map<String, String> getparams() {

        return params;

    }

}

here is the create user script

public class CreateUser extends AppCompatActivity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_create_user);

        this.setTitle("Create User");

        final EditText username1 = findViewById(R.id.Createusername);

        final EditText password1 = findViewById(R.id.CreatePassword);

        final Switch isAdmin = findViewById(R.id.isadmin);

        final Button createuser = findViewById(R.id.createuserbtn);

        if (getIntent().hasExtra("com.example.northlandcaps.crisis_response")){

            isAdmin.setVisibility(View.GONE);

        }

        createuser.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                final String username = username1.getText().toString();

                final String password = password1.getText().toString();

                final String isadmin = isAdmin.getText().toString();

                Response.Listener<String> responseListener = new Response.Listener<String>() {

                    @Override

                    public void onResponse(String response) {

                        Log.d("Response Value: ", response);

                            if (response.equals("success")){

                                Intent intent = new Intent(CreateUser.this, MainActivity.class);

                                CreateUser.this.startActivity(intent);

                            }else{

                                AlertDialog.Builder builder = new AlertDialog.Builder(CreateUser.this);

                                builder.setMessage("Register Failed")

                                        .setNegativeButton("Retry",null)

                                        .create()

                                        .show();

                        }

                    }

                };Response.ErrorListener errorListener = new Response.ErrorListener() {

                    @Override

                    public void onErrorResponse(VolleyError error) {

                        Toast.makeText(getApplicationContext(), String.valueOf(error), Toast.LENGTH_SHORT).show();

                    }

                };

                RegisterRequest registerRequest = new RegisterRequest(username,password,isadmin,responseListener,errorListener);

                RequestQueue queue = Volley.newRequestQueue(CreateUser.this);

                queue.add(registerRequest);

            }

        });



    }

here is the php script

<?php

    $db_host = '192.168.*.*:3306';

    $db_user = 'root';

    $db_pass = '';

    $db_name = 'test';

    var_dump($_POST["username"]);//line 6

    $con = mysqli_connect($db_host,'root',$db_pass,$db_name);

    if($con){

        echo "connection successful";

    }

    if (mysqli_connect_errno()) {

    printf("Connect failed: %sn", mysqli_connect_error());

    exit();

    }

    if(isset($_POST["isAdmin"]) &&  isset($_POST["username"]) && isset($_POST["password"]))

{

    $username = $_POST["username"];

    $password = $_POST["password"];

    $isAdmin = $_POST["isAdmin"];



    $statement = mysqli_prepare($con, "INSERT INTO cresidentials (username,password,isAdmin) VALUES (?, ?, ?)");

    mysqli_stmt_bind_param($statement,'ssi',$username,$password,$isAdmin);

    mysqli_stmt_execute($statement);



    if(!$statement) 

    {

         printf("Prepare failed: %sn", mysqli_error($con)); 

    }



    echo "success";

}

else

 echo "values not set";

?>

When i run this, the app creates the retry error popup message. And the output is this;

Notice: Undefined index: username in C:xampphtdocsphptestingRegister.php on line 6 NULL connection successfulvalues not set

I believe its complaining that username isnt anything. Which is a huge problem because other variables are defined below, and I do not know if they got through if the script stopped this early
I appreciate all help, thank you

Try to get your json like that in php file

$json = json_decode(file_get_contents('php://input'), true);
