So I have a two loops, one to open a directory, then check to see the files in a directory. If one of those files happens to be a direcotry then it opens another loop and goes though those files... So basically all the files in these directories are images. So when the loops go through them it will push them into a string (all the image location in html format). Then it will fwrite() the string to a file. My question is, is there a way to create a temp page that will display those images, instead of fwriting() to a file? Maybe some method ? Any help would be great!
Got a tip for us?

yeah, i know that much.. Problem is is that there is more than one dir. So for each Dir what i want is..
1 Main image for every directory that once clicked on will open the temp page that will have the rest of the files on it.
Here is my code so far....
1 Main image for every directory that once clicked on will open the temp page that will have the rest of the files on it.

PHP:

$hdl = opendir('images/photos/');
#Grabs all the files of it except ones that being with '.'
while ($dirEntry = readdir($hdl)){
if (substr($dirEntry, 0,1) != '.') {
$listing[] = $dirEntry;
}
}
#Sort the entries
natsort($listing);
#loop through the files
foreach($listing as $file){
#if one of the files is a dir then open it
#and do the same thing which is listed above.. This will only
#go to the second level of dirs.
if(is_dir("images/photos/".$file)){
$hdl2 = opendir("images/photos/".$file);
while ($dirEntry2 = readdir($hdl2)){
if (substr($dirEntry, 0, 1) != '.') {
$listing2[] = $dirEntry2;
}
}
natsort($listing2);
#Close the files
closedir($hdl);
closedir($hdl2);

}perhaps the page demonstrates what you mean, but since i can't see it...jtalerico said:
describe what you want in user terms. "a user sees this", "a user clicks on that and this happens".
i know that you asked a rather simple, direct question about php capabilities, but i find that programmers often design themselves into a corner and ask that seemingly simple, direct question which, when explored, leads to a better solution overall. that's why i'm asking.
The user wont see what is going on...
I think it is called Dynamic pages?
I want PHP to create a temp site that will only be used once (the one time the user clicks on the link).

Now I know that this isn't what you asked for, but it's a self-contained PHP script for a gallery. Just save it as gallery.php and put the images into a "gallery" folder, After you go through it, maybe you'll be inspired
P.S. It's below, since it was too long for this post. Also, it's missing some comments to get it to fit..PM me if anyone wants the full script unedited.

?>Why not make each link a form submit, and have it contain a hidden password via post. That way, even if you do access the link from some other source, it doesn't have the post password, and fails.jtalerico said:
Or, why not have a page that is deleted after an hour or so...I know you'd want to use croan tasks for this, but also, if it's frequently accessed, it won't help.
P.S. Sorry for the tripple posts.
joe -- if your example page is close to what you want, then i think you can do it w/o having to do any file writes.
lemme see if i understand the user experience:
1. the user is presented with a screen of image thumbnails and directory icons
2. if the user clicks an image thumbnail, a new window is opened with the full-size image
3. if the user clicks on a directory icon, the page reloads and presents itself as #1, but with new data
is that basically right?

assuming that's right, it's similar to what i did on one of my sites, starting here.
all that song data is being pulled from a MySQL database. if you click on one of the View links in the 'Lyrics and Info' column, you'll go to a page with a URL like this:
http://www.boxsetauthentic.com/showlyrics.php?song_id=148
that page data is being built dynamically, based on the song_id passed in. you'll see that if you go to the page showlyrics.php, you'll get an error.
is that basically what you're after?

php works w/ other databases, but aren't you working with the filesystem? for your argument, where i use song_id, you could actually use the directory path. or is the hierarchy defined in a db?
this is the code for showlyrics.php. go to the bottom, for the "main" routine, and you'll see how i first use the passed in variable.

Hmmmm... I might have to hold off on this Dynamic stuff.. First off my Mysql is not running very well on my sever.. (I think i have to delete it and install it again)... And I am not that great with MySQL.. I was kind of hoping to just keep my current code..
unless i can do something like make a function in my current php file that is like your main that i will...
get_id()
then find the the dir name that is assoicated with the get_id()... Could that work?

maybe i'm not understanding, but i don't see where you need it. the filesystem you're representing effectively works as the database, if you know what i mean.jtalerico said:
when you have a URL of the form:
foo.com/showdir.php?display_dir="images/bathroom/toilet"
... in showdir.php, you can simply access your variable display_dir:
PHP:
echo $display_dir;you don't have to do anything special to get it. i didn't mean to throw you with all the database code, but i did want to give you the whole file, so that you could match up my rendered page to the code you saw.
