MOKLETERS: UPDATE : PHP : Konverter Bilangan Desimal [LENGKAP]

Sebelumnya saya telah berbagi PHP : Konverter Bilangan Desimal [LENGKAP]. Nahh.. sekarang saya akan lebih melengkapinya dengan log in terlebih dahulu..Semoga bermanfaat :)

Langkah Pertama, buatlah new file yang bernama KonversiLengkapWithLogIn.php, dan berikut ini script atau codingnya :

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Selamat Datang, Silahkan Log In</title>
<link rel="stylesheet" href="SettingHalamanKonversiLengkapWithLogIn.css"/>
</head>
<body>
<div id="f_megacont">
<div id="f_cont">
<h1 class="tittle">Mohon diisi lengkap untuk memasuki halaman konversi Bilangan</h1>
<form method="post" action="KonversiLengkapWithLoginKonverter.php">
<table align="center">
<tr>
<th>
<label for="f_nama">Nama </label>
<td>:</td>
</th>
<td>
<input type="text" name="f_nama" id="f_nama" placeholder="Isi nama...." />
</td>
</tr>
<tr>
<th>
<label>Jenis Kelamin</label>
</th>
<td>:</td>
<td>
<input type="radio" name="f_jk" value="L" id="f_lk" />
<label for="f_lk">Laki-laki</label><br/>
<input type="radio" name="f_jk" value="P" id="f_pr" />
<label for="f_pr">Perempuan</label>
</td>
</tr>
<tr>
<th>
<label for="f_age">Umur</label>
</th>
<td>:</td>
<td>
<select name="f_age" id="f_age">
<option value="" >
------------Pilih------------
</option><br/>
<option value="A" >
>30 th
</option><br/>
<option value="B" >
<30 th
</option>
</select>
</td>
</tr>
<tr><td colspan="3" class="submit">
<input type="submit" value="Log In" name="submit"/>
</td></tr>
</table>
</form>
</div>
</div>
</body>
</html>

Langkah kedua, buatlah new file yang bernama KonversiLengkapWithLoginKonverter.php, dan berikut ini isi coding/scriptnya :

<?
error_reporting(0);
if(isset($_POST['submit'])&&$_POST['f_jk']!=''&&$_POST['f_nama']!=''&&$_POST['f_age']!=''){
$f_jk = $_POST['f_jk'];
$f_nama = $_POST['f_nama'];
$f_age = $_POST['f_age'];
if($f_jk=="L"){
if($f_age=="A"){
$ff = "Bapak";
}
else {
$ff = "agan";
}
}
else{
if($f_age=="A"){
$ff = "Ibu";
}
else {
$ff = "sist";
}
}
}
else{
echo "<script>alert('Silahkan Melengkapi Data Diri Anda');
document.location.href='KonversiLengkapWithLogIn.php';</script>";
}
$syarat = isset($_POST['f_des'])&&(isset($_POST['f_bin'])||isset($_POST['f_oct'])||isset($_POST['f_hex']))&&!(preg_match('/[^0-9]/',$_REQUEST['f_des']));
if($syarat){
$des = $_REQUEST['f_des'];
$f_oct = $_REQUEST['f_oct'];
$f_hex = $_REQUEST['f_hex'];
$f_bin = $_REQUEST['f_bin'];

//konversi ke biner
if($f_bin == "bin"){
$biner = "";
$hit = $des;
while ($hit > 0) {
if ($hit%2 == 0) {
$biner .= 0;
$hit /= 2;
}
else {
$biner .= 1;
$hit = ($hit/2)-0.5;
}
}
$biner = strrev($biner);
}

//konversi ke hexa
if($f_hex == "hex"){
$hex = "";
$hit = $des;
while($hit>0){
$hasil=$hit%16;
switch($hasil){
case 0: $hex.="0"; break;
case 1: $hex.="1"; break;
case 2: $hex.="2"; break;
case 3: $hex.="3"; break;
case 4: $hex.="4"; break;
case 5: $hex.="5"; break;
case 6: $hex.="6"; break;
case 7: $hex.="7"; break;
case 8: $hex.="8"; break;
case 9: $hex.="9"; break;
case 10: $hex.="A"; break;
case 11: $hex.="B"; break;
case 12: $hex.="C"; break;
case 13: $hex.="D"; break;
case 14: $hex.="E"; break;
case 15: $hex.="F";
default : break;
}
if($hit/16==0){
$sisa=($hit%16);
$hit=$sisa;
}
else{
$sisa=($hit/16);
$hit=$sisa%16;
}
}
$hexa = strrev($hex);
}

//konversi ke octal
if($f_oct == "oct"){
$oct = "";
$hit = $des;
while($hit>0){
$hasil=$hit%8;
switch($hasil){
case 0: $oct.="0"; break;
case 1: $oct.="1"; break;
case 2: $oct.="2"; break;
case 3: $oct.="3"; break;
case 4: $oct.="4"; break;
case 5: $oct.="5"; break;
case 6: $oct.="6"; break;
case 7: $oct.="7"; break;
default : break;
}
if($hit/8==0){
$sisa=($hit%8);
$hit=$sisa;
}
else{
$sisa=($hit/8);
$hit=$sisa%8;
}
}
$octal = strrev($oct);
}
}
else if($_POST['submit']=="Convert"){
echo "<script>alert('data yang anda masukkan kurang lengkap atau salah');</script>";
}

?>

if(isset($_POST['f_bin'])){
echo "<li>Biner = $biner</li>";
}

if(isset($_POST['f_oct'])){

if(isset($_POST['f_hex'])){

<br/>
<a href="KonversiLengkapWithLogIn.php" type="submit">Back</a>
</td>
</tr>
</table>
</form>
</div>
</div>
</body>
</html>

Langkah ketiga, kita mencoba untuk mengatur tampilannya, yaitu dengan cara membuat file baru tipe css dengan nama SettingHalamanKonversiLengkapWithLogIn.css dan berikut isi script atau codingnya :

/*
    Document   : SettingHalamanKonversiLengkapWithLogIn
    Created on : Sep 9, 2012, 12:25:31 PM
    Author     : Indri
    Description:
        Purpose of the stylesheet follows.
*/

/*
   TODO customize this sample style
   Syntax recommendation http://www.w3.org/TR/REC-CSS2/
*/

    display: block;
}

body{
margin:0;
}
#f_megacont{

[type="text"],select{
