I have use php command $file =scandir( subdirectory_name), i suppose an array of subdirectory_name is created
I do this because i am adding a new subdirectory_name every 3-4 days, the filenames inside those subdirectory are basically identical (data inside are different)
i suppose when i open that web page, it auto update that array
i wish to put this array as selection in the menu item, such that when i point the mouse to that menu item, it allow me to choose a directory name
with that chosen name (e.g. 2007-10-31), it then change a value $rd="2007-10-31"
then i choose the filename, it auto go in that directory and pick-up the file subdirectory_name/2007-10-31/file1.txt

i have done this by setting $rd="2007-10-31" and choose file, it display correctly
the remaining point is
how can i turn this $file array into the menu item selection, allow to select, put the value as $rd after that item is selected

please note that number of sub-directory is increased and may be change, and i do not wish to edit the menu_data.js or my index.php every time

do any one can give me an answer to it ????
