Not knowing which code you are using for the
bbcodes function, I will assume you are using this
POST.
You will have to move the functions to
global.php so that the shout edit will pick them up.
Then it's just a simple case of adding
quickbbshout(); where you want the bbcode to show.
Example
Code:
<body bgcolor=#1b1e25>
<?php
echo '<form method=post action=shoutbox.php>';
echo '<input type=hidden class=btn name=id value='.(int)$res['id'].'>';
echo '<center><textarea name=text rows=3 id=specialbox>'.htmlspecialchars($row['text']).'</textarea></center>';
quickbbshout();
echo '<center><br><input type=submit name=save value=Save class=btn></center>';
echo '<br><center><font size=3><font color=red><b>The Rules Of Editing ShoutPosts</b><font></center>';
echo '<br><center><font size=3><font color=white><b>Do Not Edit shouts in a way that will cause the member to be unhappy</b><font></center>'; echo '<br><center><font size=3><font color=white><b>Make sure that you are not breaching site rules in any way</b><font></center>';
echo '<br><center><font size=3><font color=white><b>Do Not Let Things Get Out Of Hand... Know When To Stop</b><font></center>';
echo '</form></body></html>'; die;
As I have said with out knowing which mod you are using, it is hard to answer your question fully.
But this should give you the idea, of what to do.
