Maybe someone somewhere has come up with another solution, however I have solved this for myself using a .htaccess file in the phorum directory with the following rule...

RewriteEngine on

RewriteCond %{QUERY_STRING} ^(.*)\%2C(.*)$ [NC]
RewriteRule ^read.php$ read.php$1?%1,%2 [L]

Its case insensitive [NC] so covers both %2C and %2c
hope that helps...

Thanks Phil, I appreciate you taking the time to answer.. I'll have a think about how to approach this.

What's happening is that the extra arguments Facebook is adding (in your attachment, the stuff in the URL starting at the &fb_action_ids=10151337719510579.....) is not being handled by Phorum's core. There is logic in the core that looks for an ampersand, and if it is found, then Phorum switches to use that to delimit query string arguments instead of commas. The Facebook constructed URL has your original Phorum IDs delimited by commas, but the ampersand has Phorum looking for its IDs using the wrong delimiter. Not finding any, Phorum will default to your list of forums.

It would technically be possible to modify Facebook URL Fixer to strip off the stuff after the ampersand, but the module runs on every single request your Phorum receives, not just the ones that come from Facebook. We wouldn't want it to blindly muck up a perfectly good URL just because there is a & symbol in it somewhere. It would also technically be possible to manipulate the query string data that Phorum reads from to include message IDs, but that is a real hacky way to fix a problem.

So, after that quickie analysis, I have to say I don't really have a satisfactory solution (just two unsatisfactory ones - well, three if I suggest just hacking the core in common.php around line 367). Maybe someone else has an idea I missed :)

hi there, thanks very much for posting these fixes..
they do seem to work, the facebook_url_fixer.php and the og: facebook meta tags..

however, i have noticed something..

when viewing the linked article on my Facebook page, sometimes facebook adds some tracking parameters to the link on my facebook page
eg [www.vetclick.com]

when these are added, the facebook_url_fixer.php does not work, and instead one goes back to the index page of the forum.

when facebook leaves these out, it works fine. it's random when FB attach this to the links on my Facebook page it seems.

is there a way around it?

PS i've attached a text file with the full link as it's sanitised in my post

I have solved the issue by applying one of the suggestions Phil gave on this thread:

[code="html4strict"]

[/code]

You can use the Facebook URL debugger to see how it's being translated (incorrectly)

I have experienced something different.
Up to a couple of weeks ago links worked fine on FB. Then for some unknown reason stopped working and although the URL fix module is active still it shows the link page. :-(((

I can understand someone who has issues to make it work but honestly can't possibly understand why in my case it stopped working.

Well, your test post just confirms that Facebook is not reaching the post properly via its URL. Their URL Linter reports a title "Cats lost in South Australia" instead of "This is just a test", meaning Facebook is parsing your forum list page (http://perfectpetfinder.com.au/lostandfound/list.php?5) because, no surprise if you followed this whole thread, Facebook can't handle Phorum's commas in the URL. Your OG properties are fine. Phorum is fine. Facebook for some reason after all this time still can't properly encode and decode a comma.

The question is, how come Facebook URL Fixer module is not doing its job? If you have that installed, and activated, your site should be working, so I am not sure what more to advise.

Re: post URL links in facebook

PerfectPetFinder — Fri, 29 Jul 2011 01:06:54 -0500

Thanks again for your reply Phil. It would be great if you can take a look. My website is http://perfectpetfinder.com.au/lostandfound/. The Phorum is not properly integrated into the rest of my site, so if you navigate away from the Phorum installation you will manually have to enter the URL again.

I decided to remove the code I quoted above from the header.tpl and instead installed your group of Facebook modules. They are really good - thanks for sharing!

However, I still have the same issue that the body of the message (or at least some of it) doesn't make it over to the Facebook wall. For example, you would expect this post to have at least included some of the "Just Lorem ipsum dolor sit amet..." when it appears on Facebook, but it doesn't. If I make a comment, that appears, but none of the text from the Phorum post.

Any advice would be greatly appreciated.

Cheers

Aaron

I've had success using the OG properties, as well as having Facebook just read the content in my pages (which it does in the absence of relevant OG properties). But in all cases within Phorum, for me it requires the Facebook URL Fixer module, and public permissions for the message read page. That second requirement has got me a few times... a page that is behind any security will not work with Facebook's robots because obviously they have no way to log in. So at the moment, that is all I have for help. If you post a link to your phorum page having your like button I can look. You can also analyze your URL using This tool which has a Facebook tab in the results which will tell you any specific problems Facebook might have. And Facebook has there own tool here: URL Linter

Hi Phil,

As you may have already guessed, but I'm a noob so I'm not too sure that I'm using the right HTML code. I'm just using my best educated guess and experimentation to try and achieve what I want. For example, instead of using the {DESCRIPTION} tag I was previously trying to use the {MESSAGES->body} tag from the read.tpl in order to display the message content on Facebook (with no success). I figured that trying to use a tag that is referenced in another template just doesn't work.

In relation to Facebook mangling Phorum URLs, I have previously installed the Facebook URL Fixer module. Is that all I need to worry about, or is there still an issue?

Your help is much appreciated.

Cheers

Aaron

Hi Aaron,

If you have confirmed that the generated HTML returned by Phorum contains what you are expecting, i.e., you can see it, then the problem is on the Facebook side. They are not reading the same page as the one with your like button. There is discussion about this at the beginning of this thread where people report Facebook is mangling Phorum URLs, which based on your description of the problem seems to be what is happening to you. Have you tried the Facebook URL Fixer module?

-phil.

Re: post URL links in facebook

PerfectPetFinder — Tue, 26 Jul 2011 19:35:50 -0500

Thanks Phil for your reply.

At the moment I am using the following code (in full) in the header template:

[code="html4strict"]
www.w3.org];
xml:lang="{LOCALE}"
lang="{LOCALE}"
xmlns:og="[ogp.me];
xmlns:fb="[www.facebook.com];

{HTML_TITLE}

perfectpetfinder.com.au]; />

[/code]

Using this code, all that appears on Facebook, after I have clicked 'like', is the title of the forum (rather than the subject of the individual post), the base URL (i.e. perfectpetfinder.com.au) and my logo. The message body from the post, where the 'like' button is located, does not appear in the Facebook post.

I really would like each 'like' button to take the content from a particular post and have that appear on Facebook, rather than just a generic information about my site as a whole.

I suppose what I'm really asking is if anyone knows what {tags} to use (e.g. {HTML TITLE}) in order to have the subject of each post appear in title, and the message body appear in the description meta for each post.

I hope this makes sense :-)

Thanks for your help!

Aaron

What exactly isn't working? The og:description property is parsed by facebook, so if you have it populated, it should work. The og:image question is kinda outside of the scope of this thread, so maybe it would be better to start another one where you ask how to get a reference to a user's uploaded images into Phorum variables that you can use in your header templates.

Re: post URL links in facebook

PerfectPetFinder — Tue, 26 Jul 2011 00:53:19 -0500

What do people use for the "og:description" tag? I'm wanting to display the content of each post- if that is possible. I've tried using
[code="html4strict"]

[/code]
But that hasn't worked...don't know why?

Also, what code would you use in order to display a user's uploaded photo in "og:image" tag?

Essentially I'm wanting to display a mini version of a user's post when someone click's 'like'. Does anyone know if this is even possible?

Some SEO people are really nervous about having multiple URLs for the same content (not that I think that it really matters for engines like Google.)

Providing alternative URLs wouldn't really work well either, would they? As long as Phorum uses the comma-driven URLs, users would cut and paste that URL to Facebook, not being aware that they should replace all commas with ampersands.

For Phorum, there's already a perfect emergency band aid available: the Facebook URL Fixer module, which works wonders, without having to change anything drastically basic.

Re: post URL links in facebook

jidanni — Fri, 14 Jan 2011 07:43:57 -0600

No, I merely suggested always providing alternative ways to reach the
same page in an emergency, just as
[en.wikipedia.org]
[en.wikipedia.org]
[en.wikipedia.org]
all reach the same page.

The administrators that use our software will love it when all of a sudden all their URLs are modified into something different.

Surely, some rewrite rules on Apache servers or possibly a module could handle the redirection to the new location, but as long as it's only Facebook not respecting the standards, we rather stick to the (valid) URL format to ensure that no migration issues can occur.

Thanks for voting for the bug at Facebook's bugtracker.

Well it seems this problem has been forgotten there. At least one can add their vote to it.

Perhaps in the future phorum could provide an alternate URL syntax containing no commas, they all being replaced with &xxx=...&yyy=... etc. That way there will be a workaround already ready the next time it happens with some other website.

Re: post URL links in facebook

Did you try adding the OG meta tags to your pages?

They look something like this:
[code="html4strict"]

[/code]

In Phorum templates you could just make it automatic for any page, put this in your header.tpl:
[code="html4strict"]

[/code]

This works for me.

anyone did any looking into the 'title' issue that I mentioned above? Or have any ideas how to solve this.

Re: post URL links in facebook

Phil Connolly — Mon, 22 Nov 2010 11:40:26 -0600

Facebook looks for information about your pages using the open graph protocol, and here is their implementation of it: [developers.facebook.com]

Try placing their meta tags on your pages and see if that works. You should test on a fresh thread, one that facebook hasn't seen yet, they seem to cache their results for a time. You can use this tool at Facebook [developers.facebook.com] to verify your tags are working.

-phil.

Added a little later: ... and I can also say that facebook doesn't parse their own meta tags consistently it seems. I have some pages that work, and some that don't, but can't tell why.

And added more a little later: I just did some tests to check that the URL facebook's parser is actually reaching the correct page. Looking at my logs, they are (with the %2C instead of commas, of course), and I can see my code to fix the commas is working. So even when facebook is parsing the wrong title (i.e., the forum title instead of the thread title), they are reading the correct URL. They seem to have an issue in their parsing... I am starting to hate facebook...

And one more addition: Arrrrgggggghhhhhhh! Sorry Facebook, you seem to be working right after all. I was testing with several forums and most worked. But one has read permissions (which I forgot). And of course facebook's parser can't read those threads, so Phorum sends back the generic content.

Re: post URL links in facebook

Phil Connolly — Mon, 22 Nov 2010 11:15:24 -0600

I tried the common.php hack works, it works. I noticed there is a parse_request hook that makes it possible to do this without a hack ;-) so here is a simple module to work around facebook's bug [www.phorum.org] until they fix it on their end.

ok so I added that and it does solve links on facebook, so that they are directed to the correct thread.

The other issue is with 'Like'.

It now likes the correct thread, however the 'title' of the page is incorrect. Facebook uses the section the thread was in as the title rather than the title of the thread.

If you have a facebook account, you can test this by visiting a thread here

[www.iloveqatar.net]

and then clicking on the like button on the bottom of the page on the toolbar.

Re: post URL links in facebook

amnesia — Tue, 16 Nov 2010 10:23:11 -0600

Yeah I've been using a url shortner but besides being tedious for users, it doesn't help with the 'like' button.

I'll give this a go!
