[SOLVED] Strange error with $_POST
Before anyone says anything about using tables for layout, it's not my form and I am going to convert it to css when it works properly 
Anyway, here is the problem. I have a BBcode form editor and it all works (well the other version I have does which hasn't got these changes).
When the user clicks on the preview button, I want the BBCode converted to html and it output so I can see what it looks like and below, display the form with the message and BBcode still intact, much like you see here when you preview a post.
When the user clicks on the post button, I want to see the message but wthout any formatting so it displays the message complete with BBcode (this is going to be stored in database in case of later editing).
The problems are when the user clicks on the post button, what is output to the browser is Post (which is the value of the Post submit button)
Also this used to work but trying it like this doesn't work anymore. When i preview the message, Bold, Italic and Underline doesn't work whereas the size, color, url etc still work.
Any ideas how I can get this to work?
- PHP: Select all
<?php
