So, lets start - open a database management program like PHPMyAdmin and run these queries.
SQL
CREATE TABLE `shoutbox` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 255 ) NOT NULL ,
`mail` VARCHAR( 255 ) NOT NULL ,
`time` VARCHAR( 255 ) NOT NULL ,
`message` TEXT NOT NULL ,
`ip` VARCHAR( 255 ) NOT NULL ,
PRIMARY KEY ( `id` )
) TYPE = MYISAM ;
CREATE TABLE `shoutbox_admin` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 255 ) NOT NULL ,
`password` VARCHAR( 255 ) NOT NULL ,
PRIMARY KEY ( `id` )
) TYPE = MYISAM ;
INSERT INTO `shoutbox_admin` (`id`,`name`,`password`) VALUES ('NULL', 'your_username', 'your_md5_hashed_password')
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 255 ) NOT NULL ,
`mail` VARCHAR( 255 ) NOT NULL ,
`time` VARCHAR( 255 ) NOT NULL ,
`message` TEXT NOT NULL ,
`ip` VARCHAR( 255 ) NOT NULL ,
PRIMARY KEY ( `id` )
) TYPE = MYISAM ;
CREATE TABLE `shoutbox_admin` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 255 ) NOT NULL ,
`password` VARCHAR( 255 ) NOT NULL ,
PRIMARY KEY ( `id` )
) TYPE = MYISAM ;
INSERT INTO `shoutbox_admin` (`id`,`name`,`password`) VALUES ('NULL', 'your_username', 'your_md5_hashed_password')
replace your_username with your username [for administration]
and your_md5_hashed_password with a password that has been md5 hashed. You can google for md5 hasher or just create a php file which contains this
CODE
<?php
$mypass='your_password';
$mypass=md5($mypass);
echo $mypass;
?>
$mypass='your_password';
$mypass=md5($mypass);
echo $mypass;
?>
Congratulations, your database is ready to be used
Next we will create a form.
Make a file called form.htm or any name you want it to be called.
Put this code in it.
HTML
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Shoutbox</title>
</head>
<body>
<iframe src='shouts.php' width='150px' height='250px'></iframe>
<form method="post" action="doit.php">
<input type='text' name='name' value='Name' onfocus='this.value=""'><br>
<input type='text' name='mail' value='E-mail' onfocus='this.value=""'><br>
<textarea name='message' onfocus='this.value=""' rows='3' cols='15'>Your text</textarea><br>
<input type='submit' value='submit' name='submit'>
</form>
</body>
</html>

<head>
<title>Shoutbox</title>
</head>
<body>
<iframe src='shouts.php' width='150px' height='250px'></iframe>
<form method="post" action="doit.php">
<input type='text' name='name' value='Name' onfocus='this.value=""'><br>
<input type='text' name='mail' value='E-mail' onfocus='this.value=""'><br>
<textarea name='message' onfocus='this.value=""' rows='3' cols='15'>Your text</textarea><br>
<input type='submit' value='submit' name='submit'>
</form>
</body>
</html>
Here we create a form which will send data to a file that will insert the data into the database
And I'm using an iframe to view the shoutbox as I couldn't find a code to refresh only one <div>.
Ok, now for the file that will read the data sent from our form and will insert it into database.
Create a file called doit.php and put this code in it.
CODE
<?php
//including the database connection
include('config.php');
//getting everything that has been submitted
$name=mysql_real_escape_string(strip_tags($_POST['name']));
$mail=mysql_real_escape_string(strip_tags($_POST['mail']));
$message=mysql_real_escape_string(strip_tags($_POST['message']));
$submit=$_POST['submit'];
//get the current time with php date() function
//note that the server time will be recorded
//more info about all functions - http://php.net
$time=date("m/d/y");
//get the ip. Note that this wont see through proxies
$ip=$_SERVER['REMOTE_ADDR'];
//just some basic error checking which
//checks if name,e-mail and message
//hasnt been left blank or with default text
if (($name!=="") || ($name!=="Name") || ($mail!=="") || ($mail!=="E-mail") || ($message!=="") || ($message!=="Your text"))
{
//inserts data into the database
$sql = "INSERT INTO shoutbox (id, name, mail, message, time, ip) VALUES ('NULL', '$name', '$mail', '$message', '$time', '$ip')";
mysql_query($sql) or die(mysql_error());
//sends the user back to the form
header("Location:".$_SERVER['HTTP_REFERER']);
}
else{
header("Location:".$_SERVER['HTTP_REFERER']);
}
?>
//including the database connection
include('config.php');
//getting everything that has been submitted
$name=mysql_real_escape_string(strip_tags($_POST['name']));
$mail=mysql_real_escape_string(strip_tags($_POST['mail']));
$message=mysql_real_escape_string(strip_tags($_POST['message']));
$submit=$_POST['submit'];
//get the current time with php date() function
//note that the server time will be recorded
//more info about all functions - http://php.net
$time=date("m/d/y");
//get the ip. Note that this wont see through proxies
$ip=$_SERVER['REMOTE_ADDR'];
//just some basic error checking which
//checks if name,e-mail and message
//hasnt been left blank or with default text
if (($name!=="") || ($name!=="Name") || ($mail!=="") || ($mail!=="E-mail") || ($message!=="") || ($message!=="Your text"))
{
//inserts data into the database
$sql = "INSERT INTO shoutbox (id, name, mail, message, time, ip) VALUES ('NULL', '$name', '$mail', '$message', '$time', '$ip')";
mysql_query($sql) or die(mysql_error());
//sends the user back to the form
header("Location:".$_SERVER['HTTP_REFERER']);
}
else{
header("Location:".$_SERVER['HTTP_REFERER']);
}
?>
Ah, config.php, forgot about it!
Create a file named like that and put this in it.
CODE
<?php
$dbhost = 'database host';
$dbname = 'database name';
$dbusername = 'database username';
$dbuserpass = 'database password';
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die('Cannot select database');
?>
$dbhost = 'database host';
$dbname = 'database name';
$dbusername = 'database username';
$dbuserpass = 'database password';
mysql_connect ($dbhost, $dbusername, $dbuserpass);
mysql_select_db($dbname) or die('Cannot select database');
?>
I guess you understand which parts you have to edit here.
Ok, now for the final part - file that will output the shouts.
Create a file named shouts.php and this is the code to put in it.
CODE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<style type="text/css">
<!--
.shout{
padding-bottom:4px;
border-bottom:1px solid #000;
width:150px;
text-align:left;
font-family:verdana;
font-size:10px;
}
-->
</style>
<title>Shoutbox</title>
</head>
<body onLoad=window.setTimeout("location.href='shouts.php'",10000)>
<?php
include('config.php');
$result = mysql_query("select * from shoutbox order by id desc limit 5");
//the while loop
while($r=mysql_fetch_array($result))
{
//getting each variable from the table
$time=$r["time"];
$id=$r["id"];
$message=$r["message"];
$name=$r["name"];
$mail=$r['mail'];
echo "<div class='shout'>
Shouted on: <i>".$time."</i><br>
By <b><a href='mailto:".$mail."'>".$name."</b></a><br>
".$message."<br>
</div><br>";
} ?>
</body>
</html>
<html>
<head>
<style type="text/css">
<!--
.shout{
padding-bottom:4px;
border-bottom:1px solid #000;

}
-->
</style>

<body onLoad=window.setTimeout("location.href='shouts.php'",10000)>
<?php

$result = mysql_query("select * from shoutbox order by id desc limit 5");
//the while loop
while($r=mysql_fetch_array($result))
{
//getting each variable from the table
$time=$r["time"];
$id=$r["id"];
$message=$r["message"];
$name=$r["name"];
$mail=$r['mail'];
echo "<div class='shout'>
Shouted on: <i>".$time."</i><br>
By <b><a href='mailto:".$mail."'>".$name."</b></a><br>
".$message."<br>
</div><br>";
} ?>
</body>
</html>
The final code just gets all data from database and is outputted with a while loop. note that you can add pagination, limit...anything to this. This is a very simple shoutbox example.
If you have any questions please ask as I may have forgotten something...
I will add the administration later as my headache is killing me. Here's my files if someone wants to see.

Oh yea, wanted to include the preview :$

Nice but when you say simple? Ever thought about clueless beyond belief TypoMage, of any language except for English?
