<table width="400" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">

<?php
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="guestbook"; // Table name 

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect server "); 
mysql_select_db("$db_name")or die("cannot select DB");

$datetime=date("y-m-d h:i:s"); //date time

$sql="INSERT INTO $tbl_name(name, email, comment, datetime)VALUES('$name', '$email', '$comment', '$datetime')";
$result=mysql_query($sql);

//check if query successful 
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='viewguestbook.php'>View guestbook</a>"; // link to view guestbook page

$tbl_name="guestbook"; // Table name 

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect server "); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

while($rows=mysql_fetch_array($result)){
?>
<table width="400" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<td><table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
