Symfony 1.2 & menu generation

If you need menu subsystem in your symfony application you can:
- make hardcore in template & layout (-);
- write own subsystem (+);
- or use plugin :)

Previously - in Symfony v.1.0 I have used sfMenuGeneratorPlugin.
As for me - it's a good plugin - I like it, but ...
- last release at 07/02/2008;
- it's compatible with symfony 1.0 (we have a newer - 1.2.1 );
- it depends on prototype.js (I like jQuery :)
- unfortunately - it doesn't support i18n.

So - let's use it - as we need.
1. Download plugin.
2. unpack it and put MenuGeneratorHelper.php to

 /symfony_project_root
    /lib
       /helper
          MenuGeneratorHelper.php

3. some changes to helper

define("__MG_CONFIG",'sf_menu_generator_');
// if you don't use prototype - you can remove this definitions
//define("__MG_JSCLASS",'sfMenuGeneratorPluginShortcuts');
//define("__MG_JSOBJECT",'sfMenuGeneratorPluginShortcuts_object');

// add own definition - it will mark active menu item
define("__MG_SELECTED_ITEM",'navSelectedMenu');

if you don't use prototype - you can remove this method & links to it

/*
function mg_add_shortcut($menuItem) {
//...
}
*/

add marker for selected menu item and fix link assembling for usage i18n -> __()

function mg_parse_menuitem($node,$module,$reverse)
{
//...

   $requestObj = sfContext::getInstance()->getRequest();
 $routeObj   = $requestObj->getAttribute("sf_route");
 
 foreach($menuItem as $key=>$value)
 {
  if(substr($key,0,5) == 'html_')
  {
    $arrKey = substr($key,5);
       $arrValue = $value;       
       $menuItemUrl = url_for($menuItem['link']);
       
       // remove /frontend_dev.php/ from URL
    if(sfContext::getInstance()->getConfiguration()->isDebug()) {
        $appConfiguration = sfContext::getInstance()->getConfiguration();
        $pattern =  "/".$appConfiguration->getApplication()."_".$appConfiguration->getEnvironment().".php";
        $menuItemUrl = ereg_replace($pattern, "", $menuItemUrl);
       }

       if($requestObj->getPathInfo() == $menuItemUrl) {
          $htmlattrs[] = "id=\"".__MG_SELECTED_ITEM."\"";
       }
       
       $htmlattrs[] = $arrKey."=\"$arrValue\"";         
  }
  if(substr($key,0,2) == 'a_')
  {
   $aattrs[] = substr($key,2)."=\"$value\"";
  }
 }
 $prepend = '';

 return $prepend.content_tag('li', 
          mg_menuitem($app_items).
          link_to(
            (isset($menuItem['text'])?__($menuItem['text']):''),
            (isset($menuItem['link'])?$menuItem['link']:'#'),
            implode(' ',$aattrs)
          ), implode(' ',$htmlattrs)
 );
}

4. Add helper to standard_helpers list (settings.yml)

all:
  .settings:
    standard_helpers:       [Partial, Cache, I18N, Form, MenuGenerator]

5. Clean up

symfony cc

that's all )
