Custom Icons

WordPress plugin that adds a Custom Icons admin screen under Design and registers SVG icons from the Media Library for the core/icon block.

Features

• Custom post type Custom Icons under Design
• Select SVG files from the Media Library
• Default icon name from the media item's post title
• Optional custom slug per icon
• Registers icons in WP_Icons_Registry
• Adds REST/editor integration so custom icons can be discovered by the block editor

Installation

1. Copy this plugin into your WordPress plugins directory.
2. Activate the plugin.
3. Ensure SVG uploads are allowed in your WordPress install.

Usage

1. Go to Design → Custom Icons.
2. Create a new Custom Icon.
3. Choose an SVG from the Media Library.
4. Optionally adjust the title and slug.
5. Publish the Custom Icon.

The icon will be registered with a name like:

custom-icons/my-icon

This can then be used by the core/icon block.

Notes

• The editor integration uses a REST endpoint at /wp-json/custom-icons/v1/icons.
• Access to the endpoint is limited to users who can edit_posts.
• SVG sanitization is intentionally conservative but lightweight.
