4.1. Implementasi Sistem Pada Android 4.1.1. Halaman Awal

Halaman awal merupakan halaman awal yang dibuka oleh website. Pada halaman ini terdapat form register dan form login. Jika, user belum memilik akun, user dapat mengisi form register dan menekan tombol register. Sedangkan, user yang sudah memiliki akun bisa mengisi form login dan menekan tombol login.

Sedangkan pada aplikasi, halaman awal akan menampilkan dua tombol yaitu,

login dan register. Jika user telah memiliki akun dapat menekan tombol login

untuk melakukan login dan menekan tombol register jika belum meliki akun

untuk melakukan proses registrasi. Potongan code Halaman Awal dapat dilihat

pada Segmen Program 4.1 dan 4.2.

Segmen Program 4.1 Halaman Login Aplikasi

Segmen Program 4.2 Halaman Registrasi Aplikasi

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

}public void login(View view) {

EditText username = findViewById(R.id.username);

EditText password = findViewById(R.id.password);

backgroundWorker.execute("login",username.getText().toString(), password.getText().toString());

}

setContentView(R.layout.activity_register);

}

public void registerr(View view) {

EditText username = findViewById(R.id.email);

EditText password = findViewById(R.id.passwordd);

EditText phone = findViewById(R.id.phone);

EditText fullname = findViewById(R.id.fullname);

System.out.println(username.getText());

System.out.println(password.getText());

System.out.println(phone.getText());

System.out.println(fullname.getText());

backgroundWorker backgroundWorker = new backgroundWorker(Register.this);

backgroundWorker.execute("register",username.getText().toString (),password.getText().toString(),fullname.getText().toString(), phone.getText().toString());}

4.1.2. Pengecekan Login

Setelah menginput form login dan menekan tombol login. Maka data yang diinputkan oleh user akan dicek apakah sesuai dengan data yang terdapat di database apa tidak. Jika ya, maka user akan masuk ke halaman utama. Potongan code pengecekan login dapat dilihat pada Segmen Program 4.3

$sql = "SELECT count(*) as c from users where email like '".$username."' and password like '".$pass."'";

$result = mysqli_query($conn, $sql);

$count = mysqli_fetch_assoc($result);

if ($count['c'] > 0) {

$q = "SELECT nama from users where email like '".$username."'";

$result = mysqli_query($conn, $q);

$n = mysqli_fetch_array($result);

$nama = $n['nama'];

echo json_encode(array('Login Success'=>$username."&".$nama));

}else{

echo "Invalid username or password.";

}

Setelah menginput form registrasi dan menekan tombol sign up. Maka data yang diinputkan user akan dicek apakah sesuai dengan ketentuan registrasi dan apakah email telah digunakan apa belum. Jika semua ketentuan terpenuhi, maka proses registrasi akan berhasil dan data user tersimpan ke dalam database.

4.1.5. Halaman Produk

Halaman produk menampilkan informasi dari semua produk yaitu, nama produk, deskripsi, harga, tanggal group buying, dll.
