How It Works

Frontend Behavior
When a visitor accesses a mapped domain:

1. Plugin detects the current domain mapping
2. Checks if a custom favicon is configured for that mapping
3. Outputs the custom favicon HTML tags
4. Suppresses WordPress default site icon to prevent conflicts

Admin Interface
The plugin adds favicon management fields to each domain mapping:

• Integrates seamlessly with the existing Multiple Domain Mapping interface
• Provides intuitive upload and selection tools
• Shows preview of selected favicons
• Validates favicon URLs automatically

Button Functions

• Upload New (Blue) – Upload fresh favicon files from your computer
• Browse Media (Green) – Select from existing files in your media library
• Search by Name (Orange) – Find specific files by filename when media browser doesn』t show all files
• Convert URL (Purple) – Convert between base domain and mapped domain URLs

File Format Support

Supported favicon formats:

• .ico – Traditional favicon format
• .png – Modern format, recommended for most uses
• .svg – Scalable vector format
• .jpg/.jpeg – JPEG images
• .gif – GIF images
