   Hi,

   I have the following code i'm using to display all of my image files from a directory. This code works perferctly everywhere i try. Except when i try within a wordpress theme:
   

   //path to directory to scan
   $directory = "http://mywebsite.com/imgs/";
   
   //get all image files with a .jpg extension.
   $images = glob($directory . "*.jpg");
   
   //print each file name
   foreach($images as $image)
   {
   echo $image;
   }

   I've tried modifying the code to display the directory dynamically, like so:
   

   $blogtheme = get_bloginfo('template_directory');
   $directory = $blogtheme . "/imgs/";

   and i can echo the $directory fine, but it doesn't return any of the files. If i echo $images i only get wordpress display the word 'Array' on my page.

   I think the problem is to do with this line, possibly the 'glob' function not working in wordpress:
   $images = glob($directory . "*.jpg");

   If anyone could provide any help, it would be much appreciated.

   Thanks!

   Not sure if this is your problem but the glob only accepts paths and not urls.
   The php manual specificly notes it.

   Edit: nevermind this post. Misread the op.

   Btw can you var_dump the $images? If so what does it return?

   I've typed in var_dump($images);

   I assume this is what you mean, and it returned this

   array(0) { }

   I've managed to get it to work if instead of using the http url, entering this for the directory

   $directory = "wp-content/themes/mytheme/imgs/";

   is there a way to replace 'mytheme' with a bit of code to automatically pull the theme name in?

   cheers

   No worries, i've solved it!

   I just added the following line
   $theme_name = get_template();
   and then changed the directory to
   $directory = "wp-content/themes/" . $theme_name . "/imgs/";

   Here's the final code:

   //path to directory to scan
   $theme_name = get_template();
   $directory = "wp-content/themes/" . $theme_name . "/imgs/";
   
   //get all image files with a .jpg extension.
   $images = glob($directory . "*.jpg");
   
   //print each file name
   foreach($images as $image)
   {
   echo $image;
   }
