RedInk Design - Smart OG Image Tag
 

Currently vBulletin's facebook open graph image tag uses what's entered in Options -> Facebook Options -> Image URL. If you leave this field blank, the <og:image> meta tag is omitted and Facebook's crawler will try to use any image found on the page.

This mod looks for the first [img] or [attach] tags in a post and uses that image for the <og:image> meta tag. This will tell facebook's crawler to use that image for the post.

This mod requires the Facebook Platform to be enabled on vBulletin (Options -> Facebook Options -> Enable Facebook Platform).

It will first look for an [img] tag is the post, if none is found, it will look for an [attach] tag. If neither is found, it will use the Image you entered in the facebook options (Options -> Facebook Options -> Image URL). If that field was left empty, it will omit the <og:image> tag which is default vBulletin behavior.

This was only tested on 4.2.0 (PL3).

Installation:
Admin -> Plugin & Products -> Manage Products -> Add/Import Product

Update 12/4/2013
Changed image priorities - avatar and site logo are not priority

Update 11/19/2013
Plugin updated to support multiple images

Installed and work fine for me
Thanks,

excuseme, I installed this product but when do you config the og:image tag??

This mod looks for the first [img] or [attach] tags in a post and uses that image for the <og:image> meta tag. This will tell facebook's crawler to use that image for the post.

You don't explicitly set the og:image tag.

I made the importation and left blank the FB Image URL, but When you create the page, the tag og: image is omitted, but there are images in the the page (article of CMS Content) :(

This mod works fine for forum thread but not work for cms article

If you want it to work with the CMS articles, what should I change in the XML? There I took a look and the only thing I've noticed is that these variables: $GLOBALS['threadinfo']['description']. There is a variable that identifies those items of CMS?

OMG, thank you I have been looking for this forever!

crap fb_opengraph_array isn't a hook in my version of vbulletin

Okay, I just inserted the plugin manually into functions_facebook.php since there isn't a comparable hook.

@Waiter - $vbulletin->options['description'] is the variable, but I don't believe it includes img and attach tags for the cms.

not work for CMS :(
Any idea for this? Thx :)

Finally! Been waiting for something like this.

As long as this works on the CMS I'm good :)

Testing.

Why does the facebook platform need to be enabled for this to work? Shouldn't it just work regardless?

but this don't work in CMS :(

I need this mod for vb 3.7 pleeeeeeeeeease......

If you're promoting a forum post why not?

because the article of CMS are automatic connect with the page of Facebook and Twitter, by RSS....if I use the forum post, I don't use the custom Meta Desciption and Key :(

Works great. Suggestion for future version.

A switch selection in admincp options that say

1) First Image
2) Provide Array

1) First Image is exactly as this mod acts.

2) Provide Array - would take all IMG and ATTACH in first post, and convert them all to

<meta property="og:image" content="http://example.com/image1.jpg" />
<meta property="og:image" content="http://example.com/image2.jpg" />

that way, when a thread is posted it will give you the option to choose the pic.

your mod doesn't account for if the site is http or https properly

had to change this line

to

I'm not quite sure I understand as if this replaces the tags when you promote the post the new tags should be there and in RSS.

Good catch, I will fix this in the next release.

So this only works for posts?

What about threads, showdisplay and forumhome?

Thanks!

Doesn't work.

This is just an extension of the default vBulletin behavior.


What doesn't?

Doesn't post image. it's just a blurry green arrow. :confused:

Why does this require the facebook platform to be enabled?

Because og tags are not inserted on vbulletin without the fb platform enabled.

Why is everyone asking if the Facebook Platform has to be enabled? If you have Facebook Connect wouldn't you need it enabled anyway?

I have a problem when using this Mod. When share a thread to Facebook, It does not show the thread tittle but the site name.

This mod does not alter existing OG tags, only the <og:image> tag. The issue you're having is with the default vBulletin tags.

I will double check with this. For the time being, when I share threads to Facebook, some show thread tittle and some show site name.
Thanks for the nice mod,

Any chance for 3.8??

Or any suggestion to make first pic in post to be og:image??

Thanks!!

Sorry, I don't have a 3.8 installation to test, I would have to set one up.

By default this plugin grabs the first pic in the post and sets that as og:image. It will look for the first [img] tag.

Thanks, the problem is that facebook is not showing any thumbnails when I share a post from my forum (vb 3.8).

I'm trying to force the first image of the post (with [IMG] bbcode) to become og: image, but don?t know how.

Bye!

Any advice will be tremendously grateful, of course..

So let me get this straight. If you have an image entered in (Options -> Facebook Options -> Image URL) this mod is useless?

This mod is for VB4 NOT VB3.

This doesn't seem to be working for me, I have the plugin installed, and FB enabled.
But when you like a thread that has images, it posts to FB but no thumbnail is displayed.

Is there something else that I need to do?
I'm running VB Version 4.2

anyone have any ideas?

It seems facebook now only supports images bigger than 200x200 for og:image tags.
