hi all
Despite my lack of ability to download images I am pressing on with my image gallery!
I would like to show a random thumbnail image on my home page. I have trawled the web and there are several easy to use scripts that perform this. However, they only allow me to use images from a single folder but I want to be able to select images from subfolders.
My main images folder contains several folders all of which contain thumbnail folders, it is from these thumbnail folders that I want to select the random pics!

Any help would be great

PHP Code:

<?php
$images = array();
$types = array('.jpg','.gif','.bmp','.jpeg','.png');    // Image types to fetch

function dirSearch($dirpath){
    global $images;
    $dh = scandir($dirpath);            // Read the contents into an array
    shift($dh);shift($dh);                // Remove the '.' and '..'
    foreach($dh as $item){
        if(is_dir("$dirpath/$item")){        // Another dir so check that as well
            dirSearch("$dirpath/$item");
        }else{                    // Check 'filetype' by extension only
            if(in_array(strtolower(strrchr($item,".")),$types)){
                $images[] = "$dirpath/$item";
            }
        }
    }
}

dirSearch('./images');                    // Directory to start search from
?>

This should fetch all images from all subdirectories to './images' and every image from './images' as well.
I'm not sure this is exactly what you asked for though.

wow
i can't argue with your response time.
So I save the text as rotate.php or something then is this file placed in my main images folder?
All the subfolders contain multiple images and a folder which contains the thumbnails, which correspond to the larger images. It is from these 'thumbnail' folders that I want the random images to come from but NOT from the medium sized pics.
Will your magic script do this?
cheers

It doesn't... yet... :P

PHP Code:

<?php
$images = array();
$types = array('.jpg','.gif','.bmp','.jpeg','.png');    // Image types to fetch
$thumbdir = 'thumbs';                 // The name of the thumbnail directories

function dirSearch($dirpath){
    global $images;
    $dh = scandir($dirpath);            // Read the contents into an array
    shift($dh);shift($dh);                // Remove the '.' and '..'
    foreach($dh as $item){
        if(is_dir("$dirpath/$item")){        // Another dir so check that as well
            dirSearch("$dirpath/$item");
        }elseif(strrchr($dirpath,"/")=="/$thumbdir"){
        // First check if we're in a thumbnail dir and if so check the filetype
            if(in_array(strtolower(strrchr($item,".")),$types)){
                $images[] = "$dirpath/$item";
            }
        }
    }
}

dirSearch('./images');                    // Directory to start search from
?>

If this works, you'll end up with an array filled with the locations of each thumbnail.

hi
Thank's again for the speedy response!
However, I haven't got it working (yet). Do I place the php file in the 'images' folder?
The name of the thumbnail folders is 'thumbs' and I have pointed to the correct path for the directory to start the search from.
Am I missing anything?
cheers

You should put the PHP script in the folder containing the 'images' folder, or change the dirSearch('./images'); to dirSearch('.');.

I have tried and tried but still it doesn't work!
Nevertheless I am not defeated and will try some more.

I will try the script as well.
Maybe I made a mistake somewhere I'm not aware of yet.

cheers, you are a star.
I have folders in folders, which makes things a bit more complicated than they might be so I may not have stumbled upon the right paths yet! This is perhaps more likely to be the problem than your script!

My bad.
I did make some mistakes.

PHP Code:

<?php
$images = array();
$types = array('.jpg','.gif','.bmp','.jpeg','.png');    // Image types to fetch
$thumbdir = 'thumbs';                 // The name of the thumbnail directories

function dirSearch($dirpath){
    global $images, $thumbdir, $types;
    $dh = scandir($dirpath);            // Read the contents into an array
    array_shift($dh);array_shift($dh);                // Remove the '.' and '..'
    foreach($dh as $item){
        if(is_dir("$dirpath/$item")){        // Another dir so check that as well
            dirSearch("$dirpath/$item");
        }elseif(strrchr($dirpath,"/")=="/$thumbdir"){
        // First check if we're in a thumbnail dir and if so check the filetype
            if(in_array(strtolower(strrchr($item,".")),$types)){
                $images[] = "$dirpath/$item";
            }
        }
    }
}

dirSearch('./images');                    // Directory to start search from
?>

hi
still no luck I'm afraid. I am sure I have the structure right but still i can't see any images. However, if you refresh the page the little cross icon where the picture should be 'blinks' as though it is looking for a random image to display but non appears. Perhaps my path is still not right, I will keep trying
cheers

Then my guess is you either expect my script to do something else than it does, or you are now making the mistakes. :P

Because when I use it in an images dir with thumb dirs and such, it does return an array of images.

Hi
still no joy. I have tried everything I can think of but to no avail so I guess I must be missing something along the line!
I have called your script 'rotate.php'.
I have a folder called 'pictures', in this folder resides my image folder, which is called 'animals'.
I have placed 'rotate.php' in the pictures folder.
I have replaced 'dirSearch('./images');' with dirSearch('./animals'); [and also tried 'dirSearch('.');'].
I have pointed my image source to read '<img src="pictures/rotate.php" />'.

am I missing something? I have tried placing rotate.php in just about every folder on my site in the hope that I may hit apon the right path if I have not understood things.
As I say if you refresh the page the image icon 'blinks' in a way that suggests that the script is trying to work but I don't see any images.

PHP Code:

<?php
$images = array();
$types = array('.jpg','.gif','.bmp','.jpeg','.png');    // Image types to fetch
$thumbdir = 'thumbs';                 // The name of the thumbnail directories

function dirSearch($dirpath){
    global $images, $thumbdir, $types;
    $dh = scandir($dirpath);            // Read the contents into an array
    array_shift($dh);array_shift($dh);                // Remove the '.' and '..'
    foreach($dh as $item){
        if(is_dir("$dirpath/$item")){        // Another dir so check that as well
            dirSearch("$dirpath/$item");
        }elseif(strrchr($dirpath,"/")=="/$thumbdir"){
        // First check if we're in a thumbnail dir and if so check the filetype
            if(in_array(strtolower(strrchr($item,".")),$types)){
                $images[] = "$dirpath/$item";
            }
        }
    }
}

dirSearch('./images');                    // Directory to start search from
$img = $images[rand(0,count($images)-1)];      // Choose random image
$file = file_get_contents($img);                     // Read image file into string

$type = strtolower(strrchr($img,"."));             // Output header depending on type
switch($type){
    case '.jpg':
    case '.jpeg':
        header('Content-type: image/jpeg');
        break;
    case '.gif':
        header('Content-type: image/gif');
        break;
    case '.bmp':
        header('Content-type: image/bmp');
        break;
    case '.png':
        header('Content-type: image/png');
        break;
}
echo $file;    // Output actual image
?>

Success!!!
You beautiful human being. May flights of angels carry you to your rest. It now does exactly what I wanted...displays a random image from multiple folders. Hoorah

One slight problem...my page displays the number of folders and pictures in my image files. Unfortunately it now sees 'rotate.php' as an image so it states '1 pictures(s)'. Is there a way to 'disguise' rotate.php so it doesn't show as a picture?

Other than that, Brilliant.

Kind words, kind words.

If you can find the script that determines how many pictures there are, maybe I could do something.
Or if it's some system with configuration options, maybe you can select the image types to count?

Hi
I shall look into this!
Meanwhile!! Is it possible to adapt your script so the folders contained in my 'animals' folder each have a random cover picture taken from within their own folder? At the moment they have a directory cover picture '<% $directory[cover_url] %>' but it would (I think) be more effective with random pics!
Cheers
