Tugas pak welly

Di bawah ini adalah script dasar yang digunakan dalam mengedit html.
Untuk menguasai bahasa pemrograman web, kita perlu belajar html.
berikut adalah contoh dasar bahasa HTML:

<HTML>
<head>
<title>Tugas Pemrograman</title>
</head>

<Body>
Membuat baris baru <br>
<font face="arial"><strong>Jenis font</strong></font> <br>
<font face="times new roman" size=20 color="red">warna font</font><br>
<hr>
<h1><font color="blue">heading</font></h1><br>
<table border="1"
<tr>
<td><a href="http://urahara-sama.blogspot.com"><font color="purple">isi pertama</font></a></td>
<td>isi kedua</td>

Buku tamu pake php

Buku tamu dalam sebuah website berguna untuk memberikan interface antara user dengan website tersebut. Dimana user dapat memberikan keluhan-keluhan ataupun respon lainnya ke website tersebut.

Berikut script yang harus dibuat untuk menciptakan sebuah buku tamu :

Buat database dulu yang memuat tabel bukutamu, yang memuat id(int, auto increment),nama(varchar),email(varchar),komentar(text).

Buat bukutamu.html

<html><body>
<h4 align=”center”>BUKU TAMU</h4>
<form name=”form1″ method=”post” action=”kirim.php”>
<div align=”center”>
<table width=”70%” border=”0″ cellpadding=”0″ cellspacing=”0″>
<td colspan=”3″> <div align=”center”><font color=”#FFFFFF” size=”3″
face=”verdana”><strong><br>
</strong><font color=”#000000″ size=”4″ face=”Verdana, Arial, Helvetica, sans-serif”>FOrM
PEnGiSiaN </font></font></div></td>
</tr>
<td width=”37%”> <div align=”right”> <font color=”#000000″ size=”3″><strong><font
face=”Verdana”>Nama</font></strong></font></div></td>
<td width=”2%”> <div align=”center”><strong><font color=”#000000″ size=”2″
face=”Verdana”>:</font></strong></div></td>
<td width=”61%”> <div align=”left”> <font color=”#FFFFFF” size=”2″
face=”Verdana”>
<input name=”nama” type=”text” id=”nama” size=”40″>
</font></div></td>
</tr>

<td> <div align=”right”><font color=”#000000″ size=”3″><strong><font
face=”Verdana”>E-mail</font></strong></font></div></td>
<td> <div align=”center”><strong><font color=”#000000″ size=”2″
face=”Verdana”>:</font></strong></div></td>
<td> <div align=”left”> <font color=”#FFFFFF” size=”2″ face=”Verdana”>
<input name=”email” type=”text” id=”email” size=”40″>
</font></div></td>
</tr>
<td> <div align=”right”><font color=”#000000″ size=”3″><strong><font
face=”Verdana”>Komentar</font></strong></font></div></td>
<td> <div align=”center”><strong><font color=”#000000″ face=”Verdana”><font
size=”2″>:</font></font></strong></div></td>
<td> <div align=”left”> <font color=”#FFFFFF” size=”2″ face=”Verdana”>
<textarea name=”komentar” rows=”7″ cols=”40″ id=”komentar”></textarea>
</font></div></td>
</tr>
<td colspan=”3″> <div align=”center”> <font color=”#FFFFFF” size=”2″
face=”Verdana”> <br>
<input type=”submit” name=”Submit” value=”Submit”>
<input name=”Reset” type=”reset” id=”Reset” value=”Reset”>
<br>
<br>
</font></div></td>
</tr>
</table>

<html><body>

buat koneksi.php

Setelah itu kita buat script kirim.php :

”);
echo(”&lttitle&gtPesan Erorr”);
echo(”&ltdiv align=center>”);
echo(”&ltFONT face=Verdana size=2 font color=red>”);
echo “Terima kasih, Anda telah mengisi buku tamu ini&ltBR>”;
echo(”&lta href=index.html&gtKembali”);
}
else
{
echo (”&ltbody bgcolor=#CCCCCC>”);
echo(”&lttitle&gtPesan Erorr”);
echo(”&ltdiv align=center>”);
echo(”&ltFONT face=Verdana size=2 font color=red>”);
echo(”Maaf!! Proses Pengiriman Gagal&ltbr>”);
echo(”&lta href=bukutamu.html&gtUlangi Lagi!”);
}}
else
{
echo (”&ltbody bgcolor=#CCCCCC>”);
echo(”&lttitle&gtPesan Error”);
echo(”&ltdiv align=center>”);
echo(”&ltFONT face=Verdana size=2 font color=red>”);
echo(”Maaf !! Ada Kesalahan Dalam Penulisan Email!!&ltBR>”);
echo(”&lta href=bukutamu.html&gtUlangi Lagi!”);
}}
else
{
echo (”&ltbody bgcolor=#CCCCCC>”);
echo(”&lttitle>++Pesan Erorr++”);
echo(”&ltdiv align=center>”);
echo(”&ltFONT face=Verdana size=2 font color=red>”);
echo(”Maaf!! Data Yang Anda Isikan Tidak Lengkap!!&ltBR>”);
echo(”&lta href=bukutamu.html&gtUlangi Lagi!”);
}}

?>
