I've put together some code to search through a directory and for all the jpg images it finds, display thumbnails and my required iptc and exif info. The problem is that I have many, many directories of photos and as it is I need an index.php file for each one. My directories are named by month and year; "1401" for January 20014, "1402" for Feb etc. and I have a set of shortcut images for each one called "1401.jpg", "1402.jpg" etc. so I use this code for users to nagivate to other directories where $shortcut has the values of 1401, 1402 etc:

echo("<a href=\" . $path . $shortcut . "\"><img src=\"shortcutimages/" . $shortcut . "\"></a>");

I'd love to allow users to navigate in a similar way without needing multiple index.php files. I would guess the best way is as follows:

On a mouseclick on a link like above, the main php (similar to below) should be re-run, replacing what's currently displayed on the screen but with new value for $dir replaced with something like $dir="../" . $shortcut; Is this the way to do it? As a newbie I apologise if this is really simple but as it is I can't seem to work it out.

thanks in advance for your help,

        while (($image = readdir($dh)) !== false)
        {
            if (preg_match("/.jpg/", $image))    // only use .jpg files
            {
                $image=$dir . "/" . $image;
                $exif = exif_read_data($image, 0, true);

                $datename[] = $timestamp . $exif_name;        // create array of date+name to allow sorting by date then retrieval of date ordered names once datestamp is removed
                $jpgcount++;                    // counts number of jpgs in folder
            }
        }
        sort($datename);                        // sort date+name array by date
        for($c=0; $c<$jpgcount; $c++)

            $image=$dir . "/" . $image;
            $size = getimagesize("$image", $info);

    It might be worth looking into a combination of [`RecursiveDirectoryIterator`](http://www.php.net/manual/en/class.recursivedirectoryiterator.php) and [`RecursiveIteratorIterator`](http://www.php.net/manual/en/class.recursiveiteratoriterator.php) instead of using an `index.php` file for every single directory. There's an example in [this answer](http://stackoverflow.com/a/20268565/1267140) – Havelock Jun 21 '14 at 09:13
  • thanks Havelock - I'm thinking more of how to refresh the screen with the information from another directory - as if the user was moving to another php file. – user3761654 Jun 21 '14 at 12:07
