## Disgrifiad

The Open Graph protocol enables any web page to become a rich object in a social
graph. For instance, this is used on Facebook to enable any web page to have the
same functionality as a Facebook Page.

While many different technologies and schemas exist and could be combined together,
there isn’t a single technology which provides enough information to richly represent
any web page within the social graph. The Open Graph protocol builds on these existing
technologies and gives developers one thing to implement. Developer simplicity is
a key goal of the Open Graph protocol which has informed many of the technical design
decisions.

#### For Developers

Use `add_action('open_graph_head_pre','your_function');` and `add_action('open_graph_head_post','
your_function');` to edit the meta data. For an instance of the class.

Always use `open_graph_instance()`

## Gosod

 1. Upload `open-graph.php` to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Set the default image for your domain (not available via admin panel in version
    1.0, replace the image `open_graph_protocol_logo.png` for now)

## Cwestiynau Cyffredin

  How to override opengraph metadata?

You can add/edit meta data by using 2 actions ‘open_graph_head_pre’ and ‘open_graph_head_post’.
‘
open_graph_head_pre’ executes before the setup takes place. ‘open_graph_head_post’
executes after the setup but before echoing meta data. I’ll add more functions for
editing in later versions.

  How to override default image of the plugin?

 * Use the `add_action('open_graph_head_pre','my_function')` .
 * In `my_function` grab an instance `$og = open_graph_instance();` and call `$og-
   >set_default_img( $url );`
 * Also you can use `'open_graph_head_post'` action and `$og->set_og_data( 'og:image'
   => $url )` but this will over ride for all pages/ posts etc

  How to override default type of homepage?

 * Use the `add_action('open_graph_head_pre','my_function')` .
 * In `my_function` grab an instance `$og = open_graph_instance();` and call `$og-
   >set_home_type( $type );`
 * Also you can use `'open_graph_head_post'` action and `if(is_home()) { $og->set_og_data('
   og:type' => $type );}`
