Google +1 for Sharedaddy

Google published on 01 June the possibility to add Google +1 to your page , which is a great service to add to the existing sharing services.

Im using Sharedaddy , and I will not install another extra plugin to support Google +1 and the Sharedaddy option to add a custom service is not prepared for dynamic services like this one. That’s because I looked to integrate the service into Sharedaddy avoiding to change to much the plugin.

Sharedaddy is Object Oriented, so its easy to create a new Sevice Class which extends Sharing_Advanced_Source. But to load your class, you need to change some files.

  • sharing-sources.php

    To make it dynamic, I created an extra file called sharing-sources-custom.php and load this file from the original Sharedaddy sharing-sources.php:

    1
    2
    3
    
    // Custom Sharing services
    require_once('sharing-sources-custom.php');
        
    
  • sharing-services.php

    This file has an array with the current services and the class name for this service, here we must change directly the function to add our new class.

    1
    2
    3
    4
    5
    6
    7
    8
    
        
    private function get_all_services() {
    // Default services
    $services = array(
    ...
    'googleplusone' => 'Share_GooglePlusOne'
    );
        
    

This two changes are enought to get your new service working, if you want you can also add images and edit admin-sharing.css to have preview in your admin panel, but the Service will be working without this.

Here is the Code for the Share_GooglePlusOne class:

Here you can download this file were you will find a patch for the actual sharedaddy version and the images for the admin panel. You only need to apply patch on wp-content/plugins/sharedaddy/ and copy the images to wp-content/plugins/sharedaddy/images/
