Description

The Open Graph protocol enables any web page to become a rich object in a social graph. Most notably, this allows for these pages to be used with Facebook’s Share Button and Graph API as well as within Twitter posts.

The Open Graph plugin inserts the Open Graph metadata into WordPress posts and pages, and provides a simple extension mechanism for other plugins and themes to override this data, or to provide additional Open Graph data.

This plugin does not directly add social plugins like the Facebook Share Button to your pages (though they’re pretty simple to add). It will however make your pages look great when shared using those kinds of tools.

How do I configure the Open Graph plugin?

You don’t; there’s nothing to configure and there is no admin page. By default, it will use whatever standard WordPress data it can to populate the Open Graph data. There are very simple yet powerful filters you can use to modify or extend the metadata returned by the plugin, described below.

How do I extend the Open Graph plugin?

There are two main ways to provide Open Graph metadata from your plugin or theme. First, you can implement the filter for a specific property. These filters are of the form opengraph_{name} where {name} is the unqualified Open Graph property name. For example, if you have a plugin that defines a custom post type named “movie”, you could override the Open Graph type property for those posts using a function like:

function my_og_type( $type ) {
    if ( get_post_type() == "movie" ) {
        $type = "movie";
    }
    return $type;
}
add_filter( 'opengraph_type', 'my_og_type' );

This will work for all of the core Open Graph properties. However, if you want to add a custom property, such as fb:admins, then you would need to hook into the opengraph_metadata filter. This filter is passed an associative array, whose keys are the qualified Open Graph property names. For example:

function my_og_metadata( $metadata ) {
    $metadata['fb:admins'] = '12345,67890';
    return $metadata;
}
add_filter( 'opengraph_metadata', 'my_og_metadata' );

Note that you may need to define the RDFa prefix for your properties. Do this using the opengraph_prefixes filter.

How does the plugin choose the images?

The plugin uses the featured image first, then the images in the post content, then the images attached to the post. If there is no image at all, it uses the site icon, the custom logo or the header image.

By default the plugin adds up to 3 images. You can change that by adding the following line to your wp-config.php

define( 'OPENGRAPH_MAX_IMAGES', 1 );

or with the opengraph_max_images filter. To add or remove image sources, use the opengraph_image_sources filter. Each source is a callable that gets the post ID and returns attachment IDs:

function my_og_image_sources( $sources ) {
    // Only use the featured image.
    return array( 'opengraph_thumbnail_image_ids' );
}
add_filter( 'opengraph_image_sources', 'my_og_image_sources' );

Does it work with Jetpack?

Yes. Jetpack also adds Open Graph metadata, so the plugin disables the Jetpack output to avoid duplicate tags. To get the Jetpack output back, deactivate this plugin.

How to enable/disable “strict mode”

The plugin populates the meta ‘name’ attribute alongside the ‘property’ attribute by default. Because both, the og:* and twitter:* names, are actually registered at https://wiki.whatwg.org/wiki/MetaExtensions, this stays compliant with the HTML5 spec. If you want to use a more strict way anyways, you can enable the strict mode by adding the following line to your wp-config.php

define( 'OPENGRAPH_STRICT_MODE', true );

Easy Plugin to Add Open Graph

By Generasi Muda Khonghucu Indonesia (generasikhonghucu) on August 7, 2022

Very easy to install and add ability to have open graph for my website

Works amazing!!

By MI (seppier) on July 26, 2021

Wow thank you for making this plugin!!! I was so stressed about thumbnails errors but now I don’t need to worry about it! Thanks!

worked on my website when others wouldn't

By stargirl1 on June 29, 2021

Great plug-in! I just installed it last night and now the og:image (large image preview) is looking correct on my posts when shared to Facebook. I normally don’t leave reviews but noticed this plug-in had very few. It worked like a charm on my website to show the big preview when others (including some well known ones) wouldn’t. I was getting frustrated and wasting time googling plug-ins that didn’t work on my site for some reason. Finally this one worked! It does what it says, and is very simple to use, no configuration needed.

Facebook previews show correctly now

By ssouthwell on December 5, 2019

Added this to a stock WordPress install, and Facebook previews for my pages began working correctly immediately! Thanks!

Does what it says on the tin

By bajandh on July 16, 2017

Runs just fine with 4.8. Had to edit the plugin and enable strict mode to make Facebook’s sharing debugger happy – it’s not happy about meta property=foo name=foo. Once that was done, the debugger showed all of the images in each post under the og:image tag, and sharing on Facebook enabled choosing one or more images for the share.
