OG

Simple and tiny Open Graph WordPress plugin to handle Facebook data.

This is a simple, tiny plugin to produce og:tags. Just that and only that. No configuration, pure power.

Plugin grabs data from content and if contains YouTube URL, then plugin try to get movie thumbnail and use it in og:image.

If post contains YouTube links, this plugin saves as post meta video thumbnail link and add it to og:image as post thumbnail.

The Facebook Open Graph Tags inserted by this plugin are:

for all type of content

  • og:locale - site locale
  • og:site_name - blog title
  • og:title - post/page/archive/tag/... title
  • og:url - the post/page permalink
  • og:type - "website" for the homepage, "article" for single content and blog for all others
  • og:description - site description
  • og:site_name - site name

for single content

  • og:image: From a specific custom field of the post/page, or if not set from the post/page featured/thumbnail image, or if it doesn't exist from the first image in the post content, or if it doesn't exist from the first image on the post media gallery, or if it doesn't exist from the default image defined in the options menu. The same image chosen here will be used and enclosure/media:content on the RSS feed.
  • article:author - author of post link
  • article:published_time - date of first article publication
  • article:modified_time - date of last article modification
  • article:tag - tags used in post

Init.

I installed OG and ... nothing happen!

Please be patient, sometimes you need more a day to see results. The reason of this is cache on Facebook. But check your plugins too and if you use and caching plugins, try to do "flush cache" on your site.

How to filter values?

Use auto filters. If you have value like this:

<meta property="og:title" content="WordPress Trunk" />

Then auto filter is created like this:

og_ + (word before ":") + _ + (word after ":") + _value

In this case:

og_og_title_value

add_filter('og_og_title_value', 'my_og_og_title_value');
function my_og_og_title_value($title)
{
    if ( is_home() ) {
        return __('This is extra home title!', 'translate-domain');
    }
    return $title;
}

How to filter whole meta tag?

Use auto filters. If you have value like this:

<meta property="og:title" content="WordPress Trunk" />

Then auto filter is created like this:

og_ + (word before ":") + _ + (word after ":") + _meta

In this case:

og_og_title_meta

add_filter('og_og_title_meta', 'my_og_og_title_meta');
function my_og_og_title_meta($title)
{
    if ( is_home() ) {
        return '<meta property="og:title" content="WordPress Title" />';
    }
    return $title;
}

How to setup default image?

Use filter "og_image_init":

add_filter('og_image_init', 'my_og_image_init');
function my_og_image_init($images)
{
    if ( is_front_page() || is_home() ) {
        $images[] = 'http://wordpress/wp-content/uploads/2014/11/DSCN0570.jpg';
    }
    return $images;
}

How to setup image on the front page?

Use filter "og_image_init":

add_filter('og_og_image_value', 'my_og_og_image_value');
