After using this I saw the description is automaticly copied from the meta description, but I’ld still like to ‘fill’ that og:description tag, if possible.
It is possible by using WPSEO_Frontend::metadesc() I think.

I tested with
WPSEO_Frontend::metadesc()
$wpseo_front->metadesc()
$wpseo_frontend->metadesc()
nothing works
WPSEO_Frontend::metadesc() inserts the normal meta tag (incl <meta> not just the value)
$wpseo_front->metadesc() and $wpseo_frontend->metadesc() break the site

anyone have a solution ???
Looks like it works when you send false as an argument to the function.
in other words WPSEO_Frontend::metadesc(false); – I’m using that right now to create my og:description tags based on the meta description from WordPress SEO.
WPSEO_Frontend::title(); grabs the title as well 🙂
Here’s the snippet i use to generate my open graph/Facebook tags with WordPress SEO
<meta property="fb:admins" content="*Facebook ID*" />
<mata property="og:author" content="Jens Ahrengot Boddum" />
<?php
$og_title = get_bloginfo('name');
if (class_exists('WPSEO_Frontend')) $og_title = WPSEO_Frontend::title();
$og_description = get_bloginfo('description');
if (class_exists('WPSEO_Frontend')) $og_description = WPSEO_Frontend::metadesc(false);
$og_type = "article";
if (is_front_page()) $og_type = "website";
$og_url = get_permalink();
if (is_front_page()) $og_url = get_bloginfo('url');
echo '<meta property="og:type" content="' . $og_type . '"/>' . "\n";
echo '<meta property="og:url" content="' . $og_url . '"/>' . "\n";
echo '<meta property="og:site_name" content="' . get_bloginfo("name") . '"/>' . "\n";
echo '<meta property="og:title" content="' . $og_title . '" />' . "\n";
echo '<meta property="og:description" content="' . $og_description . '" />' . "\n";
if (has_post_thumbnail()){
global $post;
$img_src = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'thumbnail');
echo '<meta property="og:image" content="' . $img_src[0] . '" />' . "\n";
}
?>

I ran into a new issue… what if $og_description is empty, so I adapted it a bit…
$default_description = "BLA BLA BLA";
if (class_exists('WPSEO_Frontend'))
{
$og_description = WPSEO_Frontend::metadesc(false);
if (!$og_description)
{
$og_description = $default_description;
}
}
else
{
$og_description = $default_description;
}
echo '<meta property="og:description" content="' . $og_description . '" />' . "\n";
Good to hear it works. By the way, I don’t think WPSEO_Frontend::metadesc(false) would ever return an empty string. As far as I know it grabs a description from within the content when you haven’t manually created one.
I could be wrong though …

it will if no description is entered (it did on my site)…
that’s how I got to it…
For me it just generates a meta description from my content when i don’t manually enter one.

then you probably don’t show the meta tag at all…
that makes sense. because I noticed if the tag description is not used (and i mean not show at all, empty is not ‘not used’), it takes the first x words/chars.

I ran into a new problem (probably due to updates on the plugin).
The site breaks on this piece of code (which you can see in the source code on http://www.berryplasman.com/tag/wordpress/ because if I remove it, it works fine). I think WPSEO_Frontend::metadesc(false); breaks it but I hope Yoast can answer this…
The error is “Using $this when not in object context in /public_html/wp-content/plugins/wordpress-seo/frontend/class-frontend.php on line 555”
if (class_exists('WPSEO_Frontend'))
{
$og_description = WPSEO_Frontend::metadesc(false);
if ($og_description)
{
echo '<meta property="og:description" content="' . $og_description . '" />' . "\n";
}
}
else
{
$og_description = $default_description;
}
I got this error as well. I’m about to give up though and just go with the plugin defaults.
I think you need to do something like this:
$object = new WPSEO_Frontend();
$og_title = $object->title();
But I can’t quite get it to work.
