Multiple embedforms and many to many

Hello.

This is my database : http://img41.imageshack.us/img41/9355/bdd.png

I made a tag embedform in my post form.

$tag_form = new TagForm();

$this->embedForm('tag1', $tag_form);

This is my doUpdateObject for my PostForm class.

 public function doUpdateObject($values)

  {

     parent::doUpdateObject($values); 

    $posts = $this->embeddedForms['tag1']->getObject()->getPosts();xdebug_break();

    $posts->add($this->getObject());

    $this->embeddedForms['tag1']->getObject()->setPosts($posts);

   

  }

When i submit the form all is good and my tag is linked with my post.

Then i am trying with a second embed.

$tag_form = new TagForm();

$this->embedForm('tag1', $tag_form);

$this->embedForm('tag2', $tag_form);

Now i have a problem, when i am trying the below code, only the second tag is inserted and linked in my database

 public function doUpdateObject($values)

  {

     parent::doUpdateObject($values); 

    $posts = $this->embeddedForms['tag1']->getObject()->getPosts();xdebug_break();

    $posts->add($this->getObject());

    $this->embeddedForms['tag1']->getObject()->setPosts($posts);



$posts = $this->embeddedForms['tag2']->getObject()->getPosts();xdebug_break();

    $posts->add($this->getObject());

    $this->embeddedForms['tag2']->getObject()->setPosts($posts);

   

  }



OR



foreach ($this->embeddedForms as $name => $form) {



                $posts = $this->embeddedForms[$name]->getObject()->getPosts();

                $posts->add($this->getObject());

                $this->embeddedForms[$name]->getObject()->setPosts($posts);



            }

How do i make to add and link dynamically tags in my database?

Cheers
