Files Handler

Documentation: FilesHandlerInfo.
This is the development page for the Files handler.
 


This is another a complete refactoring of the FilesManagementHandler I proposed previously. The new overview can be found at FilesManagementSolution

You should use move_uploaded_file() instead of copy(), copy() doesn't work on all systems (on mine for example it didn't).

For us poor souls who must use the Micro$oft IIS web server to host our Wikka Wakka Wiki, I suggest changing the line:
if ($file != '.' && $file != '..') {
to
if ($file != '.' && $file != '..' && $file != '_vti_cnf') {

as the web server adds the '_vti_cnf' directory automatically, which means that this directory gets shown in the file list each time.

Since the procedure is meant to read *files* and not directories (let alone recurse through them), it would be better to check for files only, rather than summing up whatever directory may need to be skipped.

So instead of:
if ($file != '.' && $file != '..')
the condition would become:
if (is_file($file))
