symfony2 {％render（controller（））％}

Question

In my main layout, i render another controller like this:

{# main layout.html.twig #}
<div id="login">
    {% render(controller("FOSUserBundle:Security:login")) %}
</div>

<div id="main">

</div>

this controller generate differents variables (lastUserName, csrf_token, error), Now how can i use these variables in my main layout.html.twig?

What you are trying to do is not intended by the symfony developers.

render() should render exactly one template if possible. This template should extend other templates. So what you can do is:

// FOSUserBundle:Security:login (Template)
{% extends main_layout.html.twig %}

{{ someVariable }}
{% block someName %}  
    YOUR DESIGN
{% endblock %}

// FOSUserBundle:Security:login (Template)    
SOME DESIGN
{{ someVariable }}
{% block someName %}  
    empty
{% endblock %}
SOME DESIGN

The variable someVariable is useable in main_layout and in the login template. You inject all variables when rendering the child template in the controller ($this -> render('templateName',array()))
