I have a simple register request script. My Android Studio is supposed to send 3 string over to the URL(php script), but the PHP doesn't receive any data, or is handling it poorly.

This is the RegisterRequest script:(its supposed to recieve values from within android studio and then push the info into the PHP script using POST method, located on localhost/ip address)

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;

    }

}

Here is the CreateUser script. Its supposed to grab strings from the XML and then call the RegisterRequest class and hand over the strings;

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);

            }

        });

And finally, here is my PHP script, which should receive Strings and put them into the db;

<?php

$db_host = 'localhost:3306';

$db_user = 'root';

$db_pass = '';

$db_name = 'test';



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

if($con){

    echo "connection successful";

}else{

    echo "connection failed";

}



$age = $_POST["isAdmin"];//line 14

$username = $_POST["username"];//line 15

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

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

if(!$statement) { printf("Prepare failed: %sn", mysqli_error($con)); }

if(!$statement) { return json_encode(['status'=>'failed','message'=>mysqli_error($con)]); }

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

mysqli_stmt_execute($statement);

if(mysqli_error($con)) { return json_encode(['status'=>'failed','message'=>mysqli_error($con)]); }//line 22



$response = array();

$response["success"] = true;  



echo json_encode($response);

?>

I hope my explanation of the script functions help you guys on debugging the problem. Also, android studio outputs this;

Notice: Undefined index: isAdmin in Register.php on line 14
Notice: Undefined index: username in Register.php on line 15
Notice: Undefined index: password in Register.php on line 16

(Is it Android studio not sending the data over? or PHP not assigning what is receiving? does PHP need a method just to put data in?)

Thank you for your help
