why are you wanting to put it into a function?

[Mattyspatty]

people dont like to do code for you.

 

function rname($dirpath,$oldFileName,$newFilename)

that is a step in the right direction, its just a case of renaming variables to work with the functions input. if you have a try but have errors or cannot seem to get it working correctly then post again and people will take a look

hello all,

            i have a one more problem regarding file renaming.Now wat i have to do is that there are subfolders(may be 1 or 2 or 3...) inside a folder and that subfolders contain several files.Now wat i want is that if i enter old filename in a textbox(that file can be present in any of the subfolder but we don't know in which subfolder it is present) and in another text box if i give new filename the "file rename" program must searches for that file placed in any of the subfolders and then rename it.........itz a typical program i think......can anybody help me doing this............
