Render an <fb:login-button> element, similar to fb_login_button. Adds a js redirect to the onlogin event via rjs.

Examples

  fb_login_and_redirect '/other_page'
  => <fb:login-button onlogin="window.location.href = &quot;/other_page&quot;;"></fb:login-button>

Like fb_login_button, this also supports the :text option

  fb_login_and_redirect '/other_page', :text => "Login with Facebook", :v => '2'
  => <fb:login-button onlogin="window.location.href = &quot;/other_page&quot;;" v="2">Login with Facebook</fb:login-button>

        def fb_login_and_redirect(url, options = {})
          js = update_page do |page|
            page.redirect_to url
          end

          text = options.delete(:text)
          
          content_tag("fb:login-button",text,options.merge(:onlogin=>js))
        end

Render an <fb:login-button> element

Examples

  <%= fb_login_button%>
  => <fb:login-button></fb:login-button>

Specifying a javascript callback

  <%= fb_login_button 'update_something();'%>
  => <fb:login-button onlogin='update_something();'></fb:login-button>

Adding options See: wiki.developers.facebook.com/index.php/Fb:login-button

  <%= fb_login_button 'update_something();', :size => :small, :background => :dark%>
  => <fb:login-button background='dark' onlogin='update_something();' size='small'></fb:login-button>

:text option allows you to set the text value of the button. *A note!* This will only do what you expect it to do if you set :v => 2 as well.

  <%= fb_login_button 'update_somethign();',
       :text => 'Loginto Facebook', :v => 2 %>
  => <fb:login-button v='2' onlogin='update_something();'>Login to Facebook</fb:login-button>

          end
        end

For information on the :app_settings argument see wiki.developers.facebook.com/index.php/JS_API_M_FB.Facebook.Init_2 While it would be nice to treat :app_settings as a hash, some of the arguments do different things if they are a string vs a javascript function and Rails’ Hash#to_json always quotes strings so there is no way to indicate when the value should be a javascript function. For this reason :app_settings needs to be a string that is valid JSON (including the {}’s).
