why can't I see my facebook canvas page? - facebook-graph-api

I've created a new app that will be accessed via a canvas page on facebook. I've entered the required domain and url, but I'm not seeing anyplace on facebook where I can actually see the canvas page. I'm in sandbox mode, does that make a difference? I'm just not seeing any option to see my canvas page. When I go to "preview" under "Review Status" I see some kind of stand in page but not my canvas page. What do I do?

Apps on Facebook are loaded into the Canvas section of the Canvas
Page. The Canvas is quite literally a blank canvas within Facebook on
which to run your app. You populate the Canvas by providing a Canvas
URL that contains the HTML, JavaScript and CSS that make up your app.
When a person using your app requests the Canvas Page, we load the
Canvas URL within an iframe on that page. This results in your app
being displayed within the standard Facebook chrome.
Here's how it works:
User goes to your canvas page (apps.facebook.com/canvasname) and they will see the normal Facebook application interface with a sidebar on the right and the other usual elements. The application will be loaded in an iframe. This iframe is loaded from the location you specify as Canvas URL. Canvas URL can be a page in your own website.
See Facebook Developers documentation for a detailed explanation.
I hope it helps!

where i can show my app likes in facebook page?

(Paginemail in search box)

What is the simplest way to create a page tab on the latest version of fb?

All I want to do is create a few pages with sign up forms for our fans and customers on our business facebook page.
I created the new app, named it and went on to the basic settings. From what I can tell I just need to set up the "page tab" info. I Named the tab, put in the page tab url, secure page tab url and uploaded a tab image.
Then I wait for it to show up on our fb page. I refresh the page and for a few seconds it looks like something is being loaded in the list of tabs. But then it stops and the layout of default tabs (photos, likes, and events) are unchanged.
The tab should link to the app url which should load inside of an iframe which will have the html from our web server.
That's how I understand it anyways.
You must add manually the application on your page through this URL: http://www.facebook.com/dialog/pagetab?app_id=APP_ID&redirect_uri=https://www.facebook.com/
Remember to replace APP_ID first.

Facebook like button is not getting displayed at all when placed it in an IFrame

Facebook like button is not getting displayed at all when placed it in an IFrame. Also the iframe is loading a page from different domain. So basically it is a cross domain scenario. I have the channel file on the iframe domain setup properly.
If you load the page from the iframe normally in another tab/window, do you see the like buttons normally?

Facebook Like button og:image needs to be scraped to be displayed

I've got a Drupal website with articles on them which have Facebook like buttons.
Now I've got all the OpenGraph metatags added on the pages and it's all working perfectly except for one thing.
Site visitors can share a page URL or like a page URL.
When a new article is added and the first person who presses the like button will not see the image added in the og:image tag.
If another person afterwards presses the like button, the og:image however is visible so it seems to me Facebook needs to scrape the page first before the og:image is added in the 'Facebook Like window'.
The Facebook share doesn't seem to suffer from this problem and does it right from the first time.
Now whenever somebody adds a new article, I'd need the URL of the article to be scraped automatically by Facebook using some PHP code or some other fix...
Anyone who knows if autoscraping a URL is possible or does anyone have an idea for a workaround?
You can use the graph API with scrape=true to force Facebook to scrape you right when you create your contents

Like Box plugin for my URL (not for Facebook Page URL)

I want to have a likebox plugin for my own URL (not a Facebook Page URL)
E.g.
http://www.example.com/product1.html
http://www.example.com/product2.html
I already have opengraph meta data, and user are able to like it, but I want to have likebox kind of plugin showing user faces...is it possible?
Facebook says the Facebook Like Box is only for Facebook pages. You could generate a like button with a show faces option for your website though.
