Print preview to meta-tags for Facebook

My b2evolution Version: B2 version: 1.10.3

I'm sure someone knows how this is done...

B2 version: 1.10.3

I've added the Facebook Share-link (http://www.facebook.com/share_partners.php) to every post on my blog, but I'm having some problems with the meta information.

For those unfamiliar with Facebook: Facebook sharing relies on two meta-tags (meta name="title" and meta name="description"). These two meta tags have the following properties: "title" should be the headline of the post, and "description" should be a short preview of what the shared item contains. I've added the following to "title":

        <meta name="title" content="<?php
                $Blog->disp('name', 'htmlhead');
        ?>" />

(http://agaricdesign.com/sharing-drupal-pages-on-facebook shows how the tags work)

So far -- so good: this works 100% :-)

Now, the problem is that I would like to use a similar kind of code to display either the first paragraph or the first 20 words (whichever is easiest) from the post in the meta name="description".

If first paragraph or first N words is difficult (or impossible), as a last resort, would it be possible to display the entire post as "description" (the blog posts are only short, 2 or 3 paragraph news items)?

Can this be done?

yes ;)

You'd need to get $Item out of $MainList and then remove all tags and cut the content at the length that you want

Thanks for your reply (I've been away for the weekend, sorry for the delay), but this seems like quite a job, removing all tags and so on, and I'm not sure how to go about doing it.

If it's easier than I assume, I'd really love some hints on how to do it, but if it is as complicated as it seems, then it's really no big deal -- I'll manage without :)

By the way, I guess you can never get this often enough; b2evolution is a great -- fantastic -- piece of software, and time and time again I'm impressed by the community here on the forums. So thanks anyhow -- you're all doing a great job!

I've just been trying to do this exact same thing. 


		$sfItem = & mainlist_get_item();
		$description = $sfItem->get_excerpt( 'entityencoded' );

The problem I'm having is that if I add the above to _html_header.inc.php it looks like that's iterating something* that means when the main code calls it (where it's supposed to be) it misses the first one (so if it's a one-post display there is no post! :( )

Is there some way of preventing this?

* I'm guessing because that "$Item = mainlist_get_item()" call is used as the condition in a while loop in the main body.

BTW rlyeh, the PHP function [url=http://www.php.net/strip_tags]strip_tags[/url] should get you in the right direction if you can solve the issue I'm having.
