This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

What does this plugin do?

This plugin lets you use a shortcode [onebox url="" title="optional title" description="optional description"] in place of a link that will display a lovely Facebook/Twitter-style box with additional information about the link.

WordPress has built-in support for some links like Google+ or Twitter, where it will generate a nice-looking embed from a link or shortcode, but what about other sites? Onebox aims to extend this by letting you turn any link into an embedded box, with extra features for some special sites, and with a fully customisable HTML template.

How does the plugin work?

Many webpages now have metadata in their header with a description and image to help sites like Twitter or Facebook generate embeds. Onebox can read this same data to generate similar embeds. In addition, the plugin makes use of a number of “parsers” to scan for specific sites and pull out even more data to use.

Where can I see it in action?

A demo site is set up at

The source is maintained on GitHub:

* file_get_contents

  • Plugin admin options screen


  1. Install the plugin as you would any other WordPress plugin and enable it
  2. Go to Settings > Onebox
  3. Change settings as required
  4. Click the Onebox button in the WordPress editor toolbar


Can I see a preview of how links will be rendered?

Sure, you can see an example at the bottom of the settings page for the plugin once installed (although hyperlink colours will be based on your theme and not previewed), and a preview will also be shown in the visual WordPress editor (requires WordPress 4.0+).

For live examples, see

Will this slow down page loads?

It shouldn’t. WordPress will initially render the link as a boring hyperlink, which will then get rendered as a onebox via AJAX after the page has loaded. Actually turning the links into boxes happens asynchronously, and it’s highly recommended that you install the APC extension for PHP to reduce the load on your server, as well as the servers you’re linking to.

How can I request extra features for

The best way is to open a ticket at GitHub. Bonus points if the site in question has a well-documented API.

What tags can I use when customising the template?

You can use any or all of the following:
* {url}
* {class}
* {favicon}
* {sitename}
* {image}
* {title}
* {description}
* {additional}
* {footer}
* {title-button}
* {footer-button}
