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
