public function Module::getInstallDirectory

public Module::getInstallDirectory()

Returns the directory where a module should be installed.

If the module is already installed, drupal_get_path() will return a valid path and we should install it there. If we're installing a new module, we always want it to go into /modules, since that's where all the documentation recommends users install their modules, and there's no way that can conflict on a multi-site installation, since the Update manager won't let you install a new module if it's already found on your system, and if there was a copy in the top-level we'd see it.

Return value

string The absolute path of the directory.

public function getInstallDirectory() {
  if ($this->isInstalled() && ($relative_path = drupal_get_path('module', $this->name))) {
    // The return value of drupal_get_path() is always relative to the site,
    // so prepend DRUPAL_ROOT.
    return DRUPAL_ROOT . '/' . dirname($relative_path);
  }
  else {
    // When installing a new module, prepend the requested root directory.
    return $this->root . '/' . $this->getRootDirectoryRelativePath();
  }
