i have get error when i try to save data:

Notice: Undefined variable: pesan in C:\xampp\htdocs\slkweb\guestbook_save.php on line 30

The code for the page is as follows:

<?php
$txtnama = isset($_POST['txtnama']);
$txtbagian = isset($_POST['txtbagian']);
$txtemail = isset($_POST['txtemail']);
$txtsaran = isset($_POST['txtsaran']);

if (trim($txtnama) =="") {
	$pesan[] = " Data Nama masih kosong";
	}
if (trim($txtbagian) =="") {
	$pesan[] = " Data Bagian masih kosong";
	}
if (trim($txtemail) =="") {
	$pesan[] = " Data e-mail masih kosong";
	}
if (trim($txtsaran) =="") {
	$pesan[] = " Data Kritik/saran masih kosong";
	}

if (! count($pesan)==0){
	$urut_pesan =0;
	echo " <b> Error input data : </b><br>";
	foreach ($pesan as $indeks=>$pesan_tampil){
		$urut_pesan++;
		echo"<font color='#ff0000'>";
		echo"$urut_pesan. $pesan_tampil <br>";
		echo"</font>";
		}
	}
else {
	include_once"library\inc.koneksi.php";
	$tgl_isi=date('y-m-d');
	$sql = "INSERT INTO tguestbook(id_gbook,nama,bagian,email,komentar,tanggal)
			VALUES ('','$txtnama','$txtbagian','$txtemail','$txtsaran','$tgl_isi')";

mysql_query($sql, $koneksi)
	or die ("gagal menyimpan buku tamu".mysql_error());

echo"<br><br><br>";
echo" pesan telah berhasil disimpan";
echo"<a href=''index.php?page=gbview'>Tampilkan</a>";
exit;
}
?>

does anybody have solution for this error??
thanks for advance..

Initialize $pesan as an empty array right after you perform all of your isset() checks.

$txtsaran = isset($_POST['txtsaran']);
$pesan = array();  // <--- Here
if (trim($txtnama) =="") {

Another issue with your script is this section:

$txtnama = isset($_POST['txtnama']); 
$txtbagian = isset($_POST['txtbagian']); 
$txtemail = isset($_POST['txtemail']); 
$txtsaran = isset($_POST['txtsaran']);

Note that the variables $txtnama, etc. are all going to be boolean values, e.g. either TRUE or FALSE - whatever [man]isset/man returns. The way you use those variables, however, suggests that you actually want to store the user's input in those variables instead.
