[PHP] Directory Walking From: Alex Augot (augota <email protected>)

Hi ya,

I've been working on an automatic page generator for the intranet
system in the company I work for. The system basically just allows
you to toss in your name, e-mail, some other information, and some HTML
It will then just use some templates and output some nicely formatted
HTML with the company letterhead on it.

In the current version it can only save to one directory, which is
annoying.
In the newer version I'm working on, I'm trying to make it walk up and
down directory's, and list the directory contents in a option box. It
will work
fine for the home directory, and one directory above home. After that,
it dies.

I talked to the local PHP guy, and he was sort of stumped too... Here's
some
snippets of the code...

<FORM ACTION="generate_test.php3" METHOD="GET">
<SELECT NAME="requested_dir" SIZE="1">
<?php
if(!isset($requested_dir)) { $requested_dir = "."; }
$current_directory = opendir($requested_dir);
while ($entry_name = readdir($current_directory))
{
 if(is_dir($entry_name))
 {
  print("<option>$entry_name</option>\n");
 }
}
print("</SELECT>\n");
print("&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\n");
?>
<INPUT TYPE="SUBMIT" VALUE="Change Dir">
</form>

That will generate the following HTML output

<FORM ACTION="generate_test.php3" METHOD="GET">
<SELECT NAME="requested_dir" SIZE="1">
<option>.</option>
<option>..</option>
<option>testing</option>
<option>testing.period</option>
</SELECT>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<INPUT TYPE="SUBMIT" VALUE="Change Dir">
</form>

In a nutshell, what I want the script to do, is know what directory it
is in.
If you click "..", it should go up to a higher level. I'll have to
define a global
variable or something, but I'm not sure. Anyone have any ideas?
