Basically I have 4 classes: 2 of them are irrelevant, a php file and an online database on 000webhost that use myphpadmin to manage mysql database.
Everything is working perfectly, except the second string value $username is not inserted and every single variable is similarly processed.
This is my first class Register
package com.example.allrateform;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.toolbox.Volley;
import org.json.JSONException;
import org.json.JSONObject;
public class Register extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
//CREATING ALL INSTANCES
final EditText FullnameEditText = (EditText) findViewById(R.id.FullnameEditText);
final EditText UsernameEditText = (EditText) findViewById(R.id.UsernameEditText);
final EditText EmailEditText = (EditText) findViewById(R.id.EmailEditText);
final EditText PasswordEditText = (EditText) findViewById(R.id.PasswordEditText);
final EditText RetypePasswordEditText = (EditText) findViewById(R.id.RetypePasswordEditText);
final Button SignupButton = (Button) findViewById(R.id.SignupButton);
//STORE VARIABLES FROM EDIT TEXTS
SignupButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String fullname = FullnameEditText.getText().toString();
final String username = UsernameEditText.getText().toString();
final String email = EmailEditText.getText().toString();
final String password = PasswordEditText.getText().toString();
//GET THE RESPONSE AND START CATEGORIES
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(Register.this, Categories.class);
startActivity(intent);
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(Register.this);
builder.setMessage("Register failed")
.create()
.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
RegisterRequest registerRequest = new RegisterRequest(fullname, username, email, password, responseListener);
RequestQueue queue = Volley.newRequestQueue(Register.this);
queue.add(registerRequest);
}
});
}
}
And this is my second class RegisterRequest
package com.example.allrateform;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.toolbox.Volley;
import org.json.JSONException;
import org.json.JSONObject;
public class Register extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
//CREATING ALL INSTANCES
final EditText FullnameEditText = (EditText) findViewById(R.id.FullnameEditText);
final EditText UsernameEditText = (EditText) findViewById(R.id.UsernameEditText);
final EditText EmailEditText = (EditText) findViewById(R.id.EmailEditText);
final EditText PasswordEditText = (EditText) findViewById(R.id.PasswordEditText);
final EditText RetypePasswordEditText = (EditText) findViewById(R.id.RetypePasswordEditText);
final Button SignupButton = (Button) findViewById(R.id.SignupButton);
//STORE VARIABLES FROM EDIT TEXTS
SignupButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final String fullname = FullnameEditText.getText().toString();
final String username = UsernameEditText.getText().toString();
final String email = EmailEditText.getText().toString();
final String password = PasswordEditText.getText().toString();
//GET THE RESPONSE AND START CATEGORIES
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(Register.this, Categories.class);
startActivity(intent);
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(Register.this);
builder.setMessage("Register failed")
.create()
.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
RegisterRequest registerRequest = new RegisterRequest(fullname, username, email, password, responseListener);
RequestQueue queue = Volley.newRequestQueue(Register.this);
queue.add(registerRequest);
}
});
}
}
And this is my php file
{
<?php
$con = mysqli_connect("localhost", "xxxxx", "xxxxx", "xxxxx");
$fullname = @($_POST['fullname']);
$username = @($_POST['username']);
$email = @($_POST['email']);
$password = @($_POST['password']);
$statement = mysqli_prepare($con, "INSERT INTO id8963226_user(fullname,username,email,password) VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($statement, "siss", $fullname, $username, $email, $password);
mysqli_stmt_execute($statement);
$response = array();
$response["success"] = true;
echo json_encode($response);?>
}
I tried to think outside the box like considering missing packages, database issues, anything; I already checked everything I could about the syntax. However if you do find any kind of error please leave a comment.
