Another BBCode Helper
I wanted a bbCode helper similar to the original smiley helper (wich is so usefull) but i couldn't find it. This is my first Ignited code and i hope it will help someone. Remarks are welcome on the forum topic.
This helper can actualy :
- Generate a javascript function needed to insert bbCodes into a form field
- Parse bbCode
- Clear bbCode tags
- Generate an array of bbCode buttons that can be clicked to be inserted
