Help with forum code

[FrozenShade]

Hello, I have been working on some forums, and i've gotten as far as posting topics, replying to topics,  etc; except  i am having troubles with adding categories. Here is what I have so far if anyone could help it would be great.
   

if($_POST['replyedit'] == 'Edit'){
	$p_id = $_POST['p_id'];
	$body = $_POST['message'];$sql = "UPDATE forum_posts SET post = '$body' WHERE p_id = '$p_id'";mysql_query($sql);$sql = "SELECT t_id FROM forum_posts WHERE p_id = '$p_id'";$result = mysql_query($sql);$r=mysql_fetch_array($result);$t_id=$r["t_id"];echo "Post Entered!<br><a href='index.php?page=16'>Back to topic list</a><br><a href='index.php?page=16&view=$t_id'>View topic</a>";} elseif($_GET['replyedit'] != 0){
	$p_id = $_GET['replyedit'];$sql = "SELECT post FROM forum_posts WHERE p_id = '$p_id'";$result = mysql_query($sql);$r=mysql_fetch_array($result);$body=$r["post"];echo "<br><center><table><form method='post' action='index.php?page=16'><tr><td class='cap'>Message</td></tr><tr><td align='center'>";include("BBcode.php");echo "<textarea cols='45' rows='20' name='message'>$body</textarea><input type='hidden' name='p_id' value='$p_id'></td></tr><tr><td align='center'><input type='submit' name='replyedit' value='Edit'></td></tr></table></form></center>";} elseif($_GET['replydel'] != 0){
	$p_id = $_GET['replydel'];$sql = "DELETE FROM forum_posts WHERE p_id = '$p_id'";mysql_query($sql);echo "Post Deleted!<br><a href='index.php?page=16'>Back to Topic List</a>";} elseif($_GET['topdel'] != 0){
	$t_id = $_GET['topdel'];$sql = "DELETE FROM forum_topics WHERE t_id = '$t_id'";mysql_query($sql);$sql = "DELETE FROM forum_posts WHERE t_id = '$t_id'";mysql_query($sql);echo "Topic Deleted!<br><a href='index.php?page=16'>Back to topic list</a>";} elseif($_POST['topic'] == 'Post Topic'){
