Hey I'm very newb to JSON, PHP and MYSQLI so please help me out here, any advice/help would be greatly appreciated.
Trying to register a new user to a local db for class project, stuck on a stupid error.
If you can help, I'd really appreciate it if you could teach me how not to do this again in the future xD
RegisterActivity Code:
public class RegisterActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
final EditText etUsername = (EditText)findViewById(R.id.etUsername);
final EditText etName = (EditText)findViewById(R.id.etName);
final EditText etSurname = (EditText)findViewById(R.id.etSurname);
final EditText etEmail = (EditText)findViewById(R.id.etEmail);
final EditText etPassword = (EditText)findViewById(R.id.etPassword);
final Button bRegister = (Button)findViewById(R.id.bRegister);
bRegister.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
final String username = etUsername.getText().toString();
final String name = etName.getText().toString();
final String surname = etSurname.getText().toString();
final String email = etEmail.getText().toString();
final String password = etPassword.getText().toString();
Response.Listener<String> responseListener = new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
boolean success = jsonResponse.getBoolean("success");
if(success){
Intent intent = new Intent(RegisterActivity.this, LoginActivity.class);
RegisterActivity.this.startActivity(intent);
}else{
AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);
builder.setMessage("Register Failed")
.setNegativeButton("Retry", null)
.create()
.show();
}
} catch (JSONException e){
e.printStackTrace();
}
}
};
RegisterRequest registerRequest = new RegisterRequest(username, name, surname, email, password, responseListener);
RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);
queue.add(registerRequest);
}
});
}
}
RegisterRequest Code:
public class RegisterRequest extends StringRequest {
private static final String REGISTER_REQUEST_URL = "http://*my local host*/Register.php";
private Map<String, String> params;
public RegisterRequest(String username, String name, String surname, String email, String password,
Response.Listener<String> listener){
super(Method.POST, REGISTER_REQUEST_URL, listener, null);
params = new HashMap<>();
params.put("username", username);
params.put("name", name);
params.put("surname", surname);
params.put("email", email);
params.put("password", password);
}
@Override
public Map<String, String> getParams() {
return params;
}
}
Register.php Code:
$username = $_POST["username"];
$name = $_POST["name"];
$surname = $_POST["surname"];
$email = $_POST["email"];
$password = $_POST["password"];
$statement = mysqli_prepare($con, "INSERT INTO user_info(username, name, surname, email, password) VALUES(?,?,?,?,?)");
mysqli_stmt_bind_param($statement, "sssss", $username, $name, $surname, $email, $password);
mysqli_stmt_execute($statment);
if (mysqli_connect_errno())
{
echo "Failed no connect to MySQL: " .mysqli_connect_error();
}
$response = array();
$response["success"] = true;
echo json_encode($response);
?>
