Im trying to connect Android Studio to a localhost MySQL server. I believe something is wrong with my php file, and I don't know how to fix it. I tried using isset, but that doesn't seem to work. Its supposed to be a simple registration script

<?php

    $db_host = '192.168.4.174:3306';

 $db_user = 'root';

 $db_pass = '';

 $db_name = 'test';



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

 if($con){

  echo "connection successful";

 }

 if (mysqli_connect_errno()) {

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

    exit();

 }



    $isAdmin = $_POST["isAdmin"];//line 16

    $username = $_POST["username"];

    $password = $_POST["password"];

 if ($isAdmin = null){

  $isAdmin = 0;

 }

 if ($username = null){

  $username = "fakename";

 }

 if ($password = null){

  $password = "fakepassword";

 }

    $statement = mysqli_prepare($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";

?>

The error says

undefined index: isAdmin, username, password at line 16-18

I tried replacing POST with isset, but that doesn't seem to work. It may be how its getting the info, so ill provide the registerrequest here;

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){

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

        params = new HashMap<>();

        params.put("username",username);

        params.put("password",password);

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

    }



    public Map<String, String> getparams() {

        return params;

    }

}

I tried to echo my variables, since everyone seems to do that, but i still get nothing. Isset just doesn't seem to do anything, and gives the same error. I might be using it wrong, however.

And just in case I'm not using jsonobjects properly, here is the register 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();

                        }

                    }

                };

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

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

                queue.add(registerRequest);

            }

        });

    }

Thanks for the help
