You can use the associative array 'opt_args' to find the options and their
args on the command line so far:


#compdef cmd
local curcontext="$curcontext" state state_descr line ret=1
typeset -A opt_args

_arguments -C : \
  '--datadir=[specify data directory]:data directory:_files -/' \
  '--template=[specify template file]:template file:->template' && ret=0

case $state in
template)
  local data_dir=$opt_args[--datadir]
  [[ -z $data_dir ]] && data_dir=/etc	# default data directory
  _files -W data_dir && ret=0
  ;;
esac

return ret
