when you suggested to OP to put the result of a query into $_POST.

the question was more like, how do i abstract the input for a template such
that it can be supplied data via $_POST in one case and the result of a
select in another.

you've recommended populating $_POST with data that has nothing to do with
HTTP POST, it is by nature globally available.

It's coming from the client, over which you have no control whatsoever. It
doesn't matter what you think you know about what it should contain, you
actually don't know anything about what it does contain and you should write
your code accordingly. You can't afford to assume anything about data coming
into your application from sources you don't control.

Terminology confusion. To me, the "result of a query" is the data, not the
resource. Personally I think it was pretty clear that's what I meant based on
what the OP was planning to do, but I can see how that might not have been
crystal clear.

That's not what he asked, but it is one possible answer to his question.

I have suggested that there is nothing wrong with modifying data in the $_POST
global variable to essentially fake that it had come from a form post. I never
suggested that it should be used as a generic global store.
I think we've started going around in circles and this is no longer benefiting
anyone. I think we're essentially saying the same thing, but where you're
relying on rules around how $_POST should be used I'm advocating vigilant
defensive programming techniques, and it seems we're going to have to agree to
disagree.

How to write a PHP coding to list out all files and directories as links to
them?
This is somewhat similar to some index pages. When new file or folder is
added to the directory, HTML page should display the newly created
file/folder together with previous ones after it is being refreshed. (prefer
in alphabatical order)
How to achieve this sort of functionality in PHP? Please provide sample
coding as well. (and any references)
Thanks.

Start with http://php.net/manual/en/function.opendir.php for a basic method.
Alternatively you can use the SPL DirectoryIterator class
http://php.net/manual/en/class.directoryiterator.php
http://php.net is your first resource for php

hi!
this form would not really be a nice solution to upload 300mb. there would
be no progress bar and no other possibility for the user to get feedback.
you should consider to use a java uploaded - or a bit nicer - a javascript
based solution like this: http://www.uploadify.com/
