+= CookBook - Template filter BBCode =

+
+Many boards allow BBCode to format posts without allowing HTML. This is a save way to allow things like urls, emails, lists, etc.
+
+This filter should be used in conjunction with the escape filter so you first escape the variable to strip out html and then filter it through bbcode.
+
+Please note that this is a quickly written piece of code, and it isn't even fully tested. It is up to you to test it and improve it :) Feel free to edit it right here to make it even better.
