It is possible to add your own custom sharing buttons to Scriptless Social Sharing, if the one you want doesn’t exist yet. This code shows you how to add a button for Facebook Messenger to your site.
First, register Facebook Messenger as an allowed protocol for links:
| add_filter( 'kses_allowed_protocols', 'prefix_allow_messenger' ); | |
| /** | |
| * Add Facebook Messenger to the list of allowed URL protocols in WordPress. | |
| * | |
| * @param $protocols | |
| * | |
| * @return array | |
| */ | |
| function prefix_allow_sms( $protocols ) { | |
| $protocols[] = 'fb-messenger'; | |
| return $protocols; | |
| } |
Then add Facebook Messenger to the list of buttons available to the plugin:
| add_filter( 'scriptlesssocialsharing_networks', 'prefix_scriptless_networks' ); | |
| /** | |
| * Add FB Messenger to settings/allowed sharing buttons | |
| * | |
| * @param $networks | |
| * | |
| * @return mixed | |
| */ | |
| function prefix_scriptless_networks( $networks ) { | |
| $networks['messenger'] = array( | |
| 'name' => 'messenger', | |
| 'label' => __( 'Facebook Messenger', 'scriptless-social-sharing' ), | |
| 'icon' => 'f39f', | |
| 'color' => '#333', // change this to whatever color you want the button to be | |
| ); | |
| return $networks; | |
| } |
Then define the URL for the Messenger button. Please note that you will have to create and add your own app ID ($app_id) for the URL to use. Also note that the hook here is scriptlesssocialsharing_messenger_url, but you will want to replace messenger with whatever you are using as the name for your button.
| add_filter( 'scriptlesssocialsharing_messenger_url', 'prefix_add_fb_messenger', 10, 3 ); | |
| /** | |
| * Add SMS to settings/allowed sharing buttons | |
| * | |
| * @param $url | |
| * @param $button | |
| * @param $attributes | |
| * | |
| * @return mixed | |
| */ | |
| function prefix_add_fb_messenger( $url, $button, $attributes ) { | |
| $app_id = ''; // enter your fb app ID here | |
| if ( ! $app_id ) { | |
| return $url; | |
| } | |
| $url = add_query_arg( | |
| array( | |
| 'link' => $attributes['permalink'], | |
| 'app_id' => $app_id, | |
| ), | |
| 'fb-messenger://share/' | |
| ); | |
| return $url; | |
| } |
These instructions are specifically for Facebook Messenger, but you can use the general concepts for any kind of sharing button you would like to create. If your preferred button uses a standard link, then you can skip the first filter–that’s just needed here because Facebook Messenger uses a different protocol for launching the link.
