Volley onResponseError = null

Question

I recently lost my work due to hardware failure. I have cloned the Android project from GitHub and rewrote the PHP scripts and rewrote the database but the registration function I have written is no longer working, despite working before the failure.

I have located the error in the logcat but cannot work out what is happening. It is in this area of the code:

 @Override
        public void onErrorResponse(VolleyError error) {
            Log.e(TAG, "Register Error: " + error.getMessage());
            Toast.makeText(getApplicationContext(),
                    error.getMessage(), Toast.LENGTH_LONG).show();
            hideDialog();
        }

and the logcat reads:

04-21 12:57:42.476 26530-26530/com.example.xxx.xxxxxE/RegisterActivity: Login Error: null

When I follow the url in the logcat it is the response that required parameters are missing from the PHP script.

{"error":true,"error_msg":"Required parameters (first name, last name, handicap, email or password) is missing!"}

so it is reaching the PHP.

The rest of the code is here:

Android Register Activity:

public class RegisterActivity extends Activity {

//Variable declarations
private static final String TAG = RegisterActivity.class.getSimpleName();
private Button btnReg;
private Button btnLinkToLogin;
private EditText inputFirstName;
private EditText inputLastName;

private EditText inputConfirmPassword;

    pDialog.setCancelable(false);

    }

    btnReg.setOnClickListener(new View.OnClickListener(){

PHP Script

    echo json_encode($response);

    $user = $db->storeUser($firstName, $lastName, $email, $handicap, $password);
    if($user){

        $response["error"] = FALSE;
        $response["uid"] = $user["unique_id"];

?>

Also of note when testing in Advanced Rest Client, it works fine and the response is received correctly. — James Marshall-Osborne, Apr 21 '17 at 12:10
