Maybe this would be off the mark relative to what you really want to do, but... Rather than trying to filter user input to assure acceptable directory paths, you could specify in advance what the acceptable paths are (e.g. using the output of "find your_web_root -type d" on the command line), and offer those as a list to choose from. If the list were in a side frame, then the navigation ought to be tolerably effective.

While I haven't tried it myself, I'm sure there would be fairly simple means available to emulate the sort of index that shows "top-level" items, with little "+" icons next to them when they contain sub-levels, and clicking on the icon expands the choices on the next level down, while clicking the name takes you to the specified item (i.e. lists the contents of that directory).
