Lax Block Binder

Block Binder is a WordPress plugin that provides a user-friendly interface for binding post meta to supported core blocks using WordPress’s Block Bindings API (available in WordPress 6.5+).

Instead of manually editing block HTML or writing custom code, editors can now: – Select a supported block in the editor – Choose which block attribute to bind (text, URL, image, etc.) – Select a post meta key from the available options – Click “Bind” to connect the meta value to the block attribute

The block will automatically display the post meta value on the frontend without hardcoding content.

Features

• Visual Block Binding Interface — Sidebar panel for intuitive meta-to-block connections
• 16+ Supported Blocks — Paragraph, Heading, Image, Button, List, Quote, Audio, Video, Columns, Cover, File, Gallery, Table, and more
• Dynamic Meta Key Discovery — Automatically discovers available post meta keys from your site
• REST API Integration — Asynchronous meta key loading for optimal performance
• Block Bindings API Compliant — Uses WordPress’s official Block Bindings API (WP 6.5+)
• Secure — Respects WordPress security standards with capability checks and nonce verification

Usage

1. Edit a Post/Page — Open the WordPress block editor
2. Select a Block — Click on a supported block (Paragraph, Heading, Image, Button, etc.)
3. Open Block Binder Panel — Find the “Block Binder” panel in the document settings sidebar
4. Choose Attribute — Select which block attribute to bind (e.g., “content” for Paragraph, “url” for Image)
5. Select Meta Key — Choose a post meta key from the dropdown (dynamically populated from your site)
6. Bind — Click the “Bind” button to connect the meta value to the block attribute
7. Unbind — Click “Unbind” to remove an existing binding

On the frontend, the bound block attribute will automatically display the post meta value without requiring additional code.
