I have been working on a class to create and check forms automatically. The problem is that, in case of a select field, the post variable can be a scalar or a hash depending on if the select field is a multiple one... is there any way to check if the variable passed to the program is a hash or a scalar???

and secondly, do i need to reset a hash if i ever need to access one if its key, value pairs after a loop?
