Fatal error: Uncaught exception 'RuntimeException'

Question

PHP version is 5.2.11 returns...

Fatal error: Uncaught exception 'RuntimeException' with message 'DirectoryIterator::__construct(/home/test/test.com/wp-content/themes/mytheme/images) [directoryiterator.--construct]: failed to open dir: No such file or directory' in /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php:462 Stack trace: #0 /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php(462): DirectoryIterator->__construct('/home/test/wie...') #1 /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php(31): get_dirs('/home/test/wie...') #2 /home/test/test.com/testing123/wp-settings.php(717): include('/home/test/wie...') #3 /home/test/test.com/testing123/wp-config.php(76): require_once('/home/test/wie...') #4 /home/test/test.com/testing123/wp-load.php(30): require_once('/home/test/wie...') #5 /home/test/test.com/testing123 in /home/test/test.com/testing123/wp-content/themes/mytheme/functions.php on line 462

Function is below...

function get_dirs($path = '.') {
$dirs = array();
foreach (new DirectoryIterator($path) as $file) {  //this is line 462
    if ($file->isDir() && !$file->isDot()) {
        $dirs[] = $file->getFilename();
    }
}

return $dirs;

}

UPDATE: The problem here I've found is that the theme was installed under a virtual directory off the main URL. My scripts are expecting that the theme is installed off the main root url...

example, the theme in this case was installed at: http://site.com/testing123/wp-content/themes/mytheme

However, I'm expecting this: http://site.com/wp-content/themes/mytheme

AND SO...

My path function fails since it does not take into consideration that it could be installed under a virtual directory.

How could i account for this scenario in my feeding of this function?

$mydir = get_dirs($_SERVER['DOCUMENT_ROOT'].'/wp-content/themes/mytheme/images');

function get_dirs($path = '.') {
$dirs = array();
foreach (new DirectoryIterator($path) as $file) {
    if ($file->isDir() && !$file->isDot()) {
        $dirs[] = $file->getFilename();
    }
}

return $dirs;

}

Answer 1

Enclose it in a try-catch block?

function get_dirs($path = '.') {
  $dirs = array();
  try{
    foreach (new DirectoryIterator($path) as $file) {  //this is line 462
    if ($file->isDir() && !$file->isDot()) {
      $dirs[] = $file->getFilename();
     }
   }
 } catch(Exception $e) {
   //log exception or process silently
   //just for test
   echo $e;
 }

 return $dirs;

Answer 2

The class is there, but apparently your images directory is not:

/home/test/test.com/wp-content/themes/mytheme/images

The key part of the message being:

failed to open dir: No such file or directory

Or, if it is there, PHP doesn't have permissions to read from it.

Answer 3

It looks like the third line is telling you that the directory cannot be found:

failed to open dir: No such file or directory

I would check your path from the script being called and adjust that appropriately
