PHP File Tree Script Help

Hey all,

I'm trying to customize a script called PHP File Tree. The documentation is here:
http://abeautifulsite.net/notebook.php?article=21

In that documentation, I think it's explained how to make it so when clicking on a file it actually opens the files -- but I'm having trouble with that part.

Here's my code related to that area:

<?php
echo php_file_tree($_SERVER['DOCUMENT_ROOT'].\"/downloadpdfs/\", \"http://www.foothillsbaptist.org/?file=[link]/\");
?>

But when I test that, it gives me the following links:
http://www.foothillsbaptist.org/?file=/home/USER/public_html/downloadpdfs/FILE.EXT/

I can't see to fix this.... any help would be appreciated.

Thanks.

I clicked the link you gave to your site, and am not too sure which links you are having problems with

I tried a few of them and they successfully open the PDF file in my browser
Can you say which links exactly you are having difficulty with

Hmmm, as with Greg, when clicking on a file my browser it seemed to behave as normal.

If you want to force the PDF to open on the client machine then you're not going to have much luck I'm afraid. Whether the file is opened or saved is up to the user.

Sorry, I probably didn't go into enough detail. Here's the test page I'm working with:

http://www.foothillsbaptist.org/php_file_tree/test.php

When I click the actual files, I simply get an Apache Directory. And when I look at the links attached, it includes the root on the end of the link.

Here's my code:

I see what you mean now!

This code you have (from your post above)
echo php_file_tree($_SERVER['DOCUMENT_ROOT']."/downloadpdfs/", "http://www.foothillsbaptist.org/downloadpdfs/?file=[link]");

Makes a link like this:

http://www.foothillsbaptist.org/downloadpdfs/?file=/home/footh4/public_html/downloadpdfs/general/giving07.pdf'
now my browser wont really know what to do with that. It can't take the "file=..." and display the PDF file from it
It will only do that from a hard link, for example this is what you want your final link to end up looking like

http://www.foothillsbaptist.org/downloadpdfs/general/giving07.pdf'
And if you copy and paste that link into your browsers URL it will load the PDF file - if your browser has PDF viewer built in
Otherwise it wont know what to do with it and ask if you want to open it with another program or save it to your PC
(This is the normal/correct behaviour)

But the way that link is made is obviously in the include file

So sould you show us the code for this file:
php_file_tree.php

I don't have time tonight unfortunately to have a good look for you (someone else might reply for you before tomorrow)
But at first glance, for the end result you are trying to accomplish that seems like an awful lot of PHP code
The Javascript I can understand as it displays folder lists/file tree views - although that of course can be done alternatively with simple href images.
