Her er hjemmeside som jeg har kopie fra,
http://www.phpeasystep.com/phptu/15.html

Jeg prøve at få det mest af det over på dansk. (men det gå ikke vildt godt lige nu)

Det er sådan at man kan skrive på enes profil/ bruger på han's profil for siden

og der har jeg fundet frem til en simple php guestebook

 <table width="400" border="0" align="center" cellpadding="3" cellspacing="0">
 <tr>
 <td><strong>Test Sign Guestbook </strong></td>
 </tr>
 </table>
 <table width="400" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
 <tr>
 <form id="form1" name="form1" method="post" action="addguestbook.php">
 <td>
 <table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
 <tr>
 <td width="117">navn</td>
 <td width="14">:</td>
 <td width="357"><input name="navn" type="text" id="navn" size="40" /></td>
 </tr>
 <td valign="top">Skrevet</td>
 <td valign="top">:</td>
 <td><textarea name="skrevet" cols="40" rows="3" id="skrevet"></textarea></td>
 </tr>
 <tr>
 <td>&nbsp;</td>
 <td>&nbsp;</td>
 <td><input type="submit" name="Submit" value="Submit" /> <input type="reset" name="Submit2" value="Reset" /></td>
 </tr>
 </table>
 </td>
 </form>
 </tr>
 </table>
 <table width="400" border="0" align="center" cellpadding="3" cellspacing="0">
 <tr>
 <td><strong><a href="viewguestbook.php">View Guestbook</a> </strong></td>
 </tr>
 </table>

så er der den her som hedder addguestbook.php

 <?php
 $host="localhost"; // Host name 
 $username="web146-a-foru-47"; // Mysql username 
 $password=" "; // Mysql password 
 $db_name="web146-a-foru-47"; // Database name 
 $tbl_name="guestbook"; // Table name
 
 // Connect to server and select database.
 mysql_connect('localhost','web146-a-foru-47','  ') or die("cannot connect server "); 
 mysql_select_db('web146-a-foru-47')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 
 }
 
 else {
 echo "ERROR";
 }
 
 mysql_close();
 ?>

Den her vise dem som er skrevet. mener jeg

 <table width="400" border="0" align="center" cellpadding="3" cellspacing="0">
 <tr>
 <td><strong>View Guestbook | <a href="guestbook.php">Skriv i Gæstebog</a> </strong></td>
 </tr>
 </table>
 <br>
 
 <?php
 
 $host="localhost"; // Host name 
 $username="web146-a-foru-47"; // Mysql username 
 $password="  "; // Mysql password 
 $db_name="web146-a-foru-47"; // Database name 
 $tbl_name="guestbook"; // Table name
 
 // Connect to server and select database.
 mysql_connect('localhost','web146-a-foru-47','  ') or die("cannot connect server "); 
 mysql_select_db('web146-a-foru-47')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">
 <tr>
 <td>ID</td>
 <td>:</td>
 <td><? echo $rows['id']; ?></td>
 </tr>
 <tr>
 <td width="117">navn</td>
 <td width="14">:</td>
 <td width="357"><? echo $rows['navn']; ?></td>
 </tr>
 <tr>
 <td valign="top">Comment</td>
 <td valign="top">:</td>
 <td><? echo $rows['skrevet']; ?></td>
 </tr>
 <tr>
 <td valign="top">Data </td>
 <td valign="top">:</td>
 <td><? echo $rows['data']; ?></td>
 </tr>
 <tr>
 <td valign="top">Time </td>
 <td valign="top">:</td>
 <td><? echo $rows['time']; ?></td>
 </tr>
 </table></td>
 </tr>
 </table>
 <BR>
 <?
 }
 mysql_close(); //close database
 ?>

Når jeg prøve at sende noget så siger den "ERROR"
