I like the share button more than the like button, thats why i'm using it. The problem is that if the title of the page change and when someone paste it into facebook is still with the old title
Sample code
I put span with a tag in the bottom of the page
http://www.facebook.com/share.php?u=http://stackoverflow.com
Using the share functionality is not a good decision since it has been deprecated and is no longer supported, as it clearly states here:
The Share button has been deprecated in favor of the Like button, and
will no longer be supported. Please use the Like button whenever
possible to drive maximum traffic to your apps.
And here:
What happened to the old Share button?
We deprecated the Share Button when we launched the Like button,
because the Like button improves clickthrough rates by allowing users
to connect with one click, and by allowing them to see which of their
friends have already connected.
With that said, to answer your question, it also written in the Like Button guide:
When does Facebook scrape my page?
Facebook needs to scrape your page to know how to display it around
the site.
Facebook scrapes your page every 24 hours to ensure the properties are
up to date. The page is also scraped when an admin for the Open Graph
page clicks the Like button and when the URL is entered into the
Facebook URL Linter. Facebook observes cache headers on your URLs - it
will look at "Expires" and "Cache-Control" in order of preference.
However, even if you specify a longer time, Facebook will scrape your
page every 24 hours.
The user agent of the scraper is: "facebookexternalhit/1.1
(+http://www.facebook.com/externalhit_uatext.php)"
To clear the cache the easiest thing is to just use the Debug Tool.

The original method for sharing links with a custom image, text and link appears to have been stripped from Facebook. I for one would love to see them bring this back.
Here is my situtation. I have a Facebook tab that loads a page that is hosted under my hosteddomains.com. I setup a Facebook app to work with my Facebook tab. When I try to use the new "Share Dialog" if the link I want to share is not the same as the app domains then i get an error and I can't share the link. Am I doing something wrong or is this what they intended to do?
IF that's what they intended to do then there is no way that this will replace what sharer.php could do. I could be on any site and share any link with an image to Facebook and have it posted to my wall.
The question is if i am on facebook tab and i want to share a link (I want a dialog box with a custom photo, title, link, and summary) and allow my users to post this custom message to there Facebook status.
Maybe i am confused about how to accomplish this, but so far i am not having much luck.
I miss the good ole days when i could just construct a URL and that would give me the ability to share what i want to share. Twitter and Pinterest have these methods.
Here are some code examples of things that I've tried that did not work:
Option #1:
The url in this option goes to page that I created on hosteddomains.com that has the Open Graph Meta Tags in it. My idea was to share these pages from my server that will direct them back to my Facebook tab. The result I was getting from this method was seeing the title of the tab from my FB page and description. The reason turned out to be that if i set the og:url to my Facebook tab page, that's the page that would get scraped. That's not what i was expecting from this method. I thought it would take the meta tags from the page i shared and the url with it. Not take all of the info from url and ignore the meta tags.
<a href="https://www.facebook.com/sharer/sharer.php?u=[URL]"
target="_parent">SHARE ON FB</a></p>
Option #2:
Tried using Facebook Share Dialog. I had an interesting time with this one. I setup a new Facebook app. I tried the Facebook tab as the URL and also my custom url to the page that has custom open graph meta tags. The facebook app has two App Domains - hosteddomain.com and websiteA.com. I also created a Page Tab section. The page tab section loads the HTML page that was loaded in the tab we made for our facebook page. Issue with this method is I don't get a custom open graph options set from my php page. I'm picking up information from the facebook tab again. At least now the dialog box shows the name of the new app. I am limited in what i can share using this method. The url i share has to belong to the App Domains. In order to have multiple app domains, I had to make that Page Tab section and then add the second url to the App Domains field, otherwise i got a warning.
<a href="https://www.facebook.com/dialog/share?app_id=[appID]&display=popup&href=[url]
&redirect_uri=[url]&ref=s" target="_blank">SHARE THIS</a>
Option #3
The last thing I tried was the fb-share-button using the Javascript SDK. I get the same result as option #1. I don't think there is much difference between these two. Option 3 here is a bit easier to deal with and cleaner code. In this example, the url is to my custom page on hosteddomains.com that has my custom open graph meta tags. That doesnt seem to matter though. It still pulls the info from the og:url meta tag. I tried removing the og:url meta tag. I get the same result. Is it the Page Tab info interfering?
<div class="fb-share-button" data-href="[url]"></div>
How long is the timeout for facebook share cache. I edited all of my pages and changes must be reflected.
If timeout is unlimited, i have to debug all pages via curl etc.
Thanks.
You can manually "clear" the facebook cache by using the Debugger.
Just go there, enter the url you changed and click "debug", that will cause the facebook bot to request the data from your servers even if it was already fetched and cached, and the new data will replace the old.
Edit
800k of pages is a lot, no doubt.
According to the Like Button doc:
Facebook scrapes your page every 24 hours to ensure the properties are
up to date. The page is also scraped when an admin for the Open Graph
page clicks the Like button and when the URL is entered into the
Facebook URL Linter. Facebook observes cache headers on your URLs - it
will look at "Expires" and "Cache-Control" in order of preference.
However, even if you specify a longer time, Facebook will scrape your
page every 24 hours.
(The URL Linter is the Debugger)
But from my experience it's not always the case, I haven't found any pattern to it, but I came across data that was months old and the cache was not clear until i manually used the debugger to extract the new data.
If you still want to manually refresh the data fb has, you can probably write a script that posts the url to the same form action in the Debugger page, I don't think they are using a csrf protection.
In that way you can automate this action for all your pages, it might take a while, but nothing too serious.
I was using window.open('https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent(url_to_share)) to make a share popup and no matter what I did, the cached share was not clearing until I did the following:
Put the URL you're trying to share into the Facebook URL Linter.
Scroll down to the "Share Preview"
Click "See this in the share dialog"
Copy the URL from that page
Put that URL in your window.open([put the url here]) popup and voila!
I want a Like button on my web site that Likes my Facebook profile (rather than my web page), so that when a user clicks it they subscribe to my Facebook posts.
I've created the Like button using the tool at https://developers.facebook.com/docs/reference/plugins/like/
Further down that page there is an FAQ entry:
Can I link the Like button to my Facebook page?
Yes. Simply specify the URL of your Facebook page in the href
parameter of the button.
So, I've edited the href parameter to point to my Facebook page. eg:
https://www.facebook.com/myfacebookid
When a user clicks the Like button it has the desired effect. The user ends up having Liked my Facebook page. This is easily verified by the user going to my Facebook profile and checking that the Like button has changed to Liked.
But. When the user clicks the Like button, and entry appears in their News Feed with a generic Facebook description. ie:
Facebook is a social utility that connects people with friends and
others who work, study and live around them. People use Facebook to
keep up with friends, upload an unlimited number of photos, post links
and videos, and learn more about the people they meet.
I don't want a generic post about Facebook to appear. I want the description to relate to my Facebook account and/or web site.
Normally, I could modify this behavior with the Opengraph og: description tag, but as the page in the href is a Facebook page and not my own, I can't control the Opengraph tags.
I'm pretty sure that this was working okay before I enabled timeline for my account, so maybe this is a timeline bug?
So, how do I add a Like button which a) Likes my Facebook profile rather than one of my own web pages, and b) Posts a description of my Facebook profile rather than give a generic Facbook description?
Are all your fields in the info part of your page filled in, and/or completed? I just tested your theory and it seemed to work as expected, only thing is I know all fields in "info" are filled it. Give that a try.
This may happen if you have filled invalid/incomplete/wrong og tags in past and later changed them. Facebook's cache creates problem sometime.
Try putting all the entries (i.e. all og tags) and then debug them here http://developers.facebook.com/tools/debug. This debugger gives a detailed info about the url with og tags and also clears the cache for you.
This should solve the problem.
You have 3 important fields that used on page opengraph: Name,Description,Profile Image.
They are used when some one post your link on Facebook, or Google or some else web service that handle opengraph.
Actually, the suggested answers currently do not work and there is an open bug / ticket on Facebook for it. Up to now, there's no fix.
The problem is that you can not use simply https://www.facebook.com/myfacebookid. You should copy and paste the exact page URL. If you have a low number of likes it would look something like https://www.facebook.com/pages/[YourPageName]/[Your page Id]/, and this is the URL that you should use at this point.
If it does not work, try also https://www.facebook.com/[YourPageName]/[Your page Id]/.
In short, copy-paste the URL, do not type it manually.
I have implemented the like button on a website. People have liked the website, and I have the option to administer that open graph object. However, on the administration page I see the following notice:
Administer Your Page
This is the administration interface for your
webpage at [...]. You can see Insights and
publish to the users that have liked your webpage. Only the
administrators of the webpage can view this interface, other users are
sent to the webpage.
This is a ghost page, because, as the notice says, only the administrator(s) can see it. I don't want the behavior of users being sent to my website. I want them to be able to stay on Facebook and see this page, just like they would see and interact with another business page.
Is there a tool or a request form to do this kind of migration (i.e. from an open graph page to a normal business page)?
I have researched for about two days for this issue, but I have not found any leads.
According to this help article, you can merge two facebook pages into one. But the constraint is that you can merge to a page with higher likes only, and the page with fewer likes will be removed. I am not sure if it works for ghost pages or not.
Shef, let me try to answer:
if you have an app myapp, that is canvas url https://apps.facebook.com/myapp
then you will have an application profile page: http://www.facebook.com/myapp [*]
So if a search your app from google or facebook, then they come to first this page,
and if they click go to app, they reach to your app.
However if you have just implemented like url: myapp.com/myitem=1
then you will have this "ghost" page. You need this ghost page, because you need somewhere
to administrate your likes
So you are asking a real page instead ghost, well this is hard to implement this request by facebook guys. Because there is like link to refer some url. So there must be some pop up asking user: 'Do you want to follow link or go to business page instead'
[*] username is not available anymore for facebook apps. see How to get name of facebook application page?
You can use the ref parameter while specifying your like button. This ref parameter will be set by Facebook, for all url's/links that appear on Facebook, i.e wherever this like action is displayed with the link to the url liked by the user. So you know when a user visits your page through Facebook. Check the following from this link:
ref - a label for tracking referrals; must be less than 50 characters and can contain alphanumeric characters and some punctuation (currently +/=-.:_). The ref attribute causes two parameters to be added to the referrer URL when a user clicks a link from a stream story about a Like action:
fb_ref - the ref parameter
fb_source - the stream type ('home', 'profile', 'search', 'other') in which the click occurred and the story type ('oneline' or 'multiline'), concatenated with an underscore.
Upon calling your url you can redirect the user to the page on Facebook that you want. Business pages on Facebook have a particular url, of course, and you can easily do the redirect.
I don't think that you have an option to migrate an open graph page to a normal business page. You can however create your page, and give it the same name as your website. The draw back here would be when users like your page on Facebook, you won't be able to accumulate the likes already garnered by your website.
EDIT
Take a look at the like box plugin (Facebook doc here ). It can be used to like pages that are on Facebook itself, from external websites. This way you will be able to accumulate your likes. You can also modify the plugin to look like a like button, not fully but almost. But you still end up creating a new page. And the old likes will not be available.
I'm trying to add a facebook "like" button to my page, and it is appearing just fine. My problem is that once it is clicked by a user, it says "Like NUMBER" then resets as if the request was canceled or something.
The weird thing is that if I try to like a page using my facebook account it works, but I tried letting a friend like some content and this behavior appeared.
I created a facebook app, specified the site url with a trailing slash, and site domain. I used the app ID with FB.init, and with the open graph tags. I can't figure what I'm doing wrong here. Any help would be appreciated.

First, for the count to work correctly, Facebook needs to have access to the page (in other words a public page). Check your URL in the linter tool (https://developers.facebook.com/tools/debug) to ensure it can been seen by Facebook.
Secondly, ensure your og: tags are correctly setup. Once again, you can use the linter tool to do that.
Facebook like buttons will show this behavior until they have been scraped by Facebook. That scraping (facebook like docs) will occur every 24 hours, when an admin clicks the like button or the url is put in the url debugger/linter. From what I can tell doing that will solve the problem for that specific link, but not any others you may have on your site.
I don't know of a generic solution for dynamically generated pages unfortunately.
