Here is my code
<? session_start();
include("$_SERVER[DOCUMENT_ROOT]\news\db_name.php");
include("$_SERVER[DOCUMENT_ROOT]\news\format_text.php");
mysql_connect(server, username, password);
mysql_select_db(db_name);
$result=mysql_query("SELECT *, DATE_FORMAT(date_posted, '%e-%m-%Y')AS date_posted, DATE_FORMAT(last_update, '%e-%m-%Y')AS last_update FROM post WHERE postid='".$_GET['post_id']."'");
$row=mysql_fetch_assoc($result);
$result1=mysql_query("SELECT category FROM categories WHERE categoryid='$row[categoryid]'");
$row_service=mysql_fetch_assoc(mysql_query("SELECT service FROM users u, post p WHERE u.userid=p.userid AND postid='$_GET[post_id]'"));
$row1=mysql_fetch_assoc($result1);
?>
<table bordercolor="black" align="center" valign="center" border=0 width="90%">
<tr>
<td align="left" class="text">
<b>category: </b><?echo $row1[category]?>
<td align=right class="text" > <b>date:</b> <?echo $row[date_posted] ?>
</td>
</td></tr><tr>
<td colspan="2" align=left class="text" ><b>service:</b> <?echo $row_service[service]?> </td></tr>
<tr>
<td align=center class="text" colspan="2"><strong><big>
<hr>
<font color="#000066"><?echo $row[title]?></strong></big>
<hr> </td></tr>
<tr>
<td class="text" colspan="2">
<? if(!empty($row['image'])) {$pic="<img src=\"../news/images/".$row['image']."\"><br><br>"; } else {$pic="";}
echo $pic;
echo format_links($row['text'])."</td></tr>";
if($row[relevant_link]) {
?>
<tr><td class="text" colspan="2"><br><br><b>link Link:</b><br><?echo format_links($row[relevant_link])?></td></tr><?}
?>
<tr><td class="text" colspan="2"><hr><b>last_update: </b><?echo $row[last_update]?></td></tr>
</table>
<center><a href="<?echo $_SERVER[HTTP_REFERER] ?>">Back</a></center>
<?
mysql_close();
?>
The problem focus on the last lines of the code ...$_SERVER[HTTP_REFERER]...
