  • No external dependencies

Installation

1. Upload the add-to-some folder to /wp-content/plugins/
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Configure settings under Settings > AddToSome

Configuration

Basic Settings

• Icon Style: Set the size of share button icons (10-300 pixels)
• Share Buttons: Enable/disable individual sharing services
• Placement: Choose where buttons appear on single posts

Advanced Options

Facebook App ID

For enhanced Facebook sharing features:

1. Visit developers.facebook.com
2. Create a new app (Consumer type)
3. Copy the App ID from your app dashboard
4. Paste it in the plugin settings

Without an App ID, the plugin uses Facebook's basic sharer functionality.

X (Twitter) Handle

Add your X handle to include "via @yourhandle" in shared tweets.

Architecture

The plugin follows a modern, object-oriented architecture with clear separation of concerns:
