I am currently researching ShortCodes but when I send in HTML as a parameter it is encoded so when output it is not processed as HTML by the browser it is processed as text. e.g. <, > have all been converted etc.
If you use paramtest is the shortcode function <b>test</b> is output instead of the text test bolded.
I think I need a reverse function of wp specialchars function?
Any help appreciated.
