Question

I am newbie in creating apps for Facebook and I would like to ask you about a few things.

I created my first app, in the settings I set up the domain URL, canvas URL, etc… when I load the app via apps.facebook.com/my_app_name the app is working, but also when I visit the page via the canvas URL I configured.

Is there any way to only allow access to the app only when loaded inside the Facebook chrome?

Also, in the app that I made are some links, buttons, etc. and when you hover over them with the mouse you can see my own domain in the status bar below. Is there a way to change that?

Answer 1

When your page is called from within Facebook it receives a signed_request via $_POST. You can show the page based on that, or perhaps redirect to apps.facebook.com/yourapp instead.

See also: signed_request

As for the links that show in the status bar, you need to rewrite those links to point to apps.facebook.com/yourapp/somepage. When you do that, the link target should be set to _top.

Alternatively, you could do things like this:

<a href="#" data-url="/mypage?id=123" class="hidden-url">click me</a>

And then with jQuery:

$(function() {
    $('a.hidden-url').on('click', function(evt) {
        location = $(this).data('url');
        return false;
    });
});
