drupal_match_path() for multiple wildcard patterns?

Question

I want to add some CSS and JS to multiple matched wildcard URL patterns. According to Add javascript to multiple specific urls, I can use a wildcard using drupal_match_path() and that works well for one pattern. However, I am trying to use a few patterns to add the same JS and CSS. So far I've tried these:

  // By path matching wildcard patterns.
  $path = drupal_get_path_alias();
  $pattern = 'portfolio/* || photo-blog';

and

  $path = drupal_get_path_alias();
  $pattern = 'portfolio/*, photo-blog';

and

  $pattern = 'portfolio/*' 'photo-blog';
  $path = drupal_get_path_alias();

... but none of these work. I am guessing it may not be possible in the context of:

if (drupal_match_path($path, $pattern)) {
// add JS and CSS based on above
  }

The API page you've linked describes the format of the $patterns argument:

$patterns: String containing a set of patterns separated by \n, \r or \r\n.

These are types of carriage returns, in different Operating Systems.

Sooo .... did you try:

 $pattern = "portfolio/*\nphoto-blog";
 // or
 $pattern = "portfolio/*\rphoto-blog";
 // or
 $pattern = "portfolio/*\r\nphoto-blog";

EDIT:

 // for platform portability heh
 $pattern = "portfolio/*" . PHP_EOL . "photo-blog";

This one got me so many times - drupal_match_path() is expecting a newline character to separate the paths. Add this function to your project and never look back:

function _get_path_pattern_string(array $items) {
  return implode(PHP_EOL, $items);
}

Example usage (overly verbose):

$patterns = array('portfolio/*', 'photo-blog', 'something-else');
$pattern_string = _get_path_pattern_string($patterns);
if (drupal_match_path($path, $pattern_string)) {
  // Do something...
}
