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.locati on from index.html, something like this:
<a href="./php/getimages.php?d ocument.locatio n" ....
(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("Locatio n: gallery/").
Am I understanding you wrong?
Dan
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;
-
}
-

Recognized Expert Top Contributor - 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.
Works great thanks so much...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
