Newbie -- pass document.location to php

[roadiee]

I am sure this must be common but I can't seem to find how to do it.

I have a file structure as follows:
php
- getimages.php
gallery
- index.html
- image1.jpg
- image2.jpg
- image3.jpg

inside of index.html I have
<a href="http://bytes.com/submit/304/ ../php/getimages.php">View images</a>

what I want to do is in getimages.php be able to set the directory to ./gallery

Naturally I can hard code this but I would like to have a generic solution just in case I move my php folder, or have a more complex directory structure.

I thought i could solve this in two ways
1) send document.location from index.html, something like this:
<a href="./php/getimages.php?document.location" ....
(notice I have index.html, not a php file and I can't change this)
2) in getimages.php somehow determine where the request is coming from, maybe use REQUEST_URI

But I am sure there must be a more elegant approach.

I still don't see your reasoning for why you wouldn't just redirect to that folder, but use php header("Location: gallery/").

Am I understanding you wrong?

Sorry I am not sure I understand what you are asking ( or perhaps how header works) but my issue is that I also want to call the same file getimages.php and it needs to load the files from the location of the calling index.html.

So if index.html is in ../gallery/ then run get images from ../gallery. If index.html is in ../gallery2/ then it should get the images from gallery 2 etc.

So my side structure is more complex than this, and looks more like:
php
- getimages.php
2002
- 01gallery
- index.html
- image1.jpg
- image2.jpg
- 01gallery
- index.html
- image1.jpg
- image2.jpg
- 02gallery
- index.html
- image1.jpg
- image2.jpg
- 04gallery
- index.html
- image1.jpg
- image2.jpg
etc (for 2003, 2004, ...)

Does that make sense?

I did write this bit of code to get it to work but it seems a bit of an overkill:

function getcallingdir(){
 
  $callingdir= strstr($_SERVER[HTTP_REFERER],$_SERVER[HTTP_HOST]);
  $callingdir = str_replace($_SERVER[HTTP_HOST],$_SERVER[DOCUMENT_ROOT],$callingdir);
  $callingdir = trim(str_replace("index.html","",$callingdir));
 
  return $callingdir;
 }

function get_calling_dir() {
    $match = array();
    if (preg_match("/([^/]+)(/index\.html)?$/", $_SERVER['HTTP_REFERER'], $match)) {
        return $match[1];
    }
    return false;
}

Do let me know if it doesn't work.
