public function Module::getInstallDirectory

Returns the directory where a module should be installed.

If the module is already installed, ModuleExtensionList::getPath() 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.

    // The return value of ExtensionList::getPath() 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();
