<meta property="fb:admins" content="1234" />
<meta property="fb:app_id" content="your_app_id" />

// Set Facebook meta data
$document = JFactory::getDocument();
$uri = JURI::getInstance();
$document->setMetaData('og:url', $uri->toString());
$document->setMetaData('og:title', (K2_JVERSION == '15') ? htmlspecialchars($document->getTitle(), ENT_QUOTES, 'UTF-8') : $document->getTitle());
$document->setMetaData('og:type', 'article');
$facebookImage = 'image'.$params->get('facebookImage', 'Small');
if ($item->$facebookImage)
{
$parts = parse_url($item->$facebookImage);
if (JFile::exists(JPATH_SITE.$parts))
{
$image = substr(JURI::root(), 0, -1).str_replace(JURI::root(true), '', $item->$facebookImage);
$document->setMetaData('og:image', $image);
$document->setMetaData('image', $image);
}

Hi,

This has nothing to do with K2. You need to either add those tags directly in your template's source code or look for a plugin that will do that.

I know the question was asked about a year ago, but maybe somebody would like to see an answer how to add the App ID and some other Open Graph meta tags
You can make an override in of the templates - ex. category.php or item.php
Right after
in the top of the file you can add the following code

The code seems correct.

You could omit this part since it is most likely already present in your template.
defined('_JEXEC') or die;

This code should be placed in the template's index.php file or a file that is present in all views.

I've corrected to avoid misunderstanding

Got, it.

My answer is the same however, you can place it in K2 overrides but it would still not appear on every page.

You need to place this code in a core template file, like the index.php file.

I understand what you mean, and if the site is using K2 overall you are absolutely correct.

But I don't think I'm the only one, which have some subsites without K2, where we add Open Graph in another way.
In such cases it can be done with overrides in K2

For the sake of consistency, for additional og:tags I always use a helper file which is loaded on top of the index.php file.

This way all the functionality is bundled (or bootstrapped) in one file and regardless of the extensions I am using the tags will always be present in one location.
