1. Pada laporan ke-4 kali ini, saya akan menjelaskan tentang penambahan field di
android, mysql dan server.
Tetap Persiapan file yang kemarin, contoh di bawah ini :
A. Database
Buka localhost/phpmyadmin
Buat database dengan nama pakaian
B. PHP
Buka folder htdocs ( C : xampp/htdocs )
Buat sebuah folder bernama pakaian
di dalam folder server, buat sebuah file dengan nama index.php
C. Android
Buat sebuah project (File -> New Android Application) dan beri nama pakaian
Pada lokasi src pastikan sudah ada file :
a. MainActivity.java
b. Koneksi.Java
c. Pakaian.java
File yang di atas adalah file yang kemarin saya, upload di laporan ke-3 saya. Namun
kali ini, saya sudah mengganti kontennya seperti gambar-gambar yang ada di bawah
ini.
Database
Ekseskusi query ini untuk membuat tabel_biodata
Jika dibrowse, maka hasilnya akan kelihatan seperti gambar berikut :
2. PHP - index.php
Buka server.php yang berada di lokasi C:xampphtdocsserverindex.php, lalu ketikkan source
code berikut :
<form method="post" action="simpan_data.php">
<table border="0" align="center">
<tr>
<td colspan="5" align="center"><h2>From Inputan</h2></td>
</tr>
<tr>
<td>Merk</td>
<td>:</td>
<td><input type="text" name="merk"/></td>
</tr>
<tr>
<td>Jenis</td>
<td>:</td>
<td><input type="text" name="jenis"/></td>
</tr>
<tr>
<td>Ukuran</td>
3. <td>:</td>
<td><input type="text" name="ukuran"/></td>
</tr>
<tr>
<td>Harga</td>
<td>:</td>
<td><input type="number" name="harga"/></td>
</tr>
<tr>
<td></td>
<td></td>
<td><input type="submit" value="Simpan"/>
<input type="reset" value="Reset"/></td>
</tr>
</table>
</form>

Untuk hasil running bisa lihat gambar di bawah ini…
Inilah hasil running project.
17. Selesai.. maaf jika tampilannya kurang cantik, anda bisa memperindah tampilannya dengan CSS
<HTML> dan lain sebagainya…
