Get files from a directory in random order using php (xampp)

Question

i'm building a wordpress theme and i'm trying to get the all the jpg files from a directory in random order using php.... im using Xampp on win7 (localhost).

this is the code:

<? 
    $dir =  get_template_directory_uri().'/images/top/';

    $file_display = array ('jpg', 'jpeg');
    if(file_exists($dir) == false){
        echo 'Directory \'', $dir, '\' not found';
    } else {
       $dir_contents = scandir($dir);
       shuffle($dir_contents);
       foreach ($dir_contents as $file) {
           $file_type = strtolower(end(explode('.', $file)));
           if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true){ 
                echo '<img  src="', $dir, '/', $file, '" alt="', $file, '" />';    
           }
       }
   } 
?>

i always get

Directory 'http://localhost/ni/wp-content/themes/A/images/top/' not found

i also tried to change

$dir =  get_template_directory_uri().'/images/top/';

to:

    $dir = "C:\xampp\htdocs\Ni\wp-content\themes\A\images\top\";

but still no luck, any help would be appreciated!

Do you have and if in front in front of the (file_exists($dir) == false) test? — Mark Baker

try replacing get_template_directory_uri by get_template_directory, because the get_template_directory_uri gives an URI (and you don't want that) — EaterOfCode

@EaterOfCorpses As of PHP 5.0 file_exists accepts HTTP (amongst a few other protocols) so it shouldn't matter so long as OP is using PHP5. — ɴᴀᴛᴇ ᴅᴇᴠ

using get_template_directory() outputs: C:\xampp\htdocs\Ni/wp-content/themes/A/images/top/ with mixed slashes (linux windows syle?) and i get Directory '' not found — Firezilla12

This is how i made it work.

  <? 
            $dir =  get_template_directory().'/images/top';
            $imageDir= get_template_directory_uri().'/images/top';
            $file_display = array ('jpg', 'jpeg');
            if (file_exists($dir) == false) {
              echo 'Directory \'', $dir, '\' not found';
            } else {
              $dir_contents = scandir($dir);
              shuffle($dir_contents);
              foreach ($dir_contents as $file) {
                $file_type = strtolower(end(explode('.', $file)));
                if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true) {
                  echo '<img src="', $imageDir, '/', $file, '"  />';
                }
              }
            } 
  ?>

by using get_template_directory() to get the array. and get_template_directory_uri() to show the images. thank you all for helping me out to get to this...

Note that in most cases it's better to use get_stylesheet_directory() rather than get_template_directory() if you're trying to load assets because if you're using a child theme the former will return the child theme's directory, whereas the latter will return the parent theme's directory, and will thus cause you to miss child-theme assets.
