scandir to only show folders, not files

Question

I have a bit of PHP used to pulled a list of files from my image directory - it\'s used in a form to select where an uploaded image will be saved. Below is the code:

Answer 1

The is_dir() function requires an absolute path to the item that it is checking.

$base_dir    = get_home_path() . '/downloads'; 
//get_home_path() is a wordpress function
$sub_dirs = array();
$dir_to_check = scandir($dir);
foreach ($dir_to_check as $item){
  if ($item != '..' && $item != '.' && is_dir($base_dir . "/" . $item)){
    array_push($sub_dirs, $item);
  }
}
