_menu_helper_active_get_active_path()

Get active menu path for the current page.

Return value

The assigned active menu item link path for the current page or an empty string if there is no active link path.

Code

<?php
function _menu_helper_active_get_active_path() {
  $patterns = variable_get('menu_helper_active_patterns', NULL);

  // If no patterns or the current page is already a menu item then exit
  if ( $patterns == NULL || _menu_helper_active_is_current_path_a_menu_link() ) {
    return NULL;
  }

  // Get actual path and alias
  $q = $_GET['q'];
  $alias = drupal_get_path_alias($q);

  // Reduce the number of checks (aka preg_match()) in loop by first comparing the actual path and alias
  // Also confirm that the path still exits using menu_get_item();
  if ($q == $alias) {
    // Only look for $q, which is faster
    foreach ($patterns as $pattern => $path) {
      if ( preg_match($pattern, $q) && menu_get_item($path)) {
        return $path;
      }
    }
  }
  else {
    // Look for $q and alais, which is a few micro seconds slower
    foreach ($patterns as $pattern => $path) {
      if ( (preg_match($pattern, $q) || preg_match($pattern, $alias)) && menu_get_item($path) ) {
        return $path;
      }
    }
  }

  return NULL;
