Note Submitter: chris@dontwantspam.com ---- Don't make the mistake that I did in assuming that get_func_arg(1) can be used like it's an array. If you try to check if it is set like empty(get_func_arg(1)) or is_set(get_func_arg(1)) will return a parse error. Using if (get_func_arg(1)) { ... } without a second argument will return a warning (this may or may not display, depending on your error settings).
