+# BlockRegistrar Usage Guide
+
+The `BlockRegistrar` class provides automatic block registration from `block.json` files. This guide shows how to use it in themes and plugins.

+
+## Basic Usage
+
+### 1. Extend BlockRegistrar
+
+Create a class that extends `BlockRegistrar` and implement the required method:
+
+```php
+ Array of paths to the blocks directories.
+ */
+ public function get_blocks_directory(): array {
+ return [ YOUR_BLOCKS_DIRECTORY ];
+ }
+}
+```
+
+### 2. Automatic Registration
+
+The framework automatically discovers and registers your `Blocks` class through `ModuleInitialization`. No manual registration needed!
+
+## Theme Implementation
+
+### Directory Structure
+
+```
+your-theme/
+├── src/
+│ └── Blocks.php
+├── blocks/
+│ ├── example-block/
+│ │ ├── block.json
+│ │ ├── edit.js

+│ ├── block.json
+│ ├── edit.js
+│ ├── index.js
+│ ├── markup.php
+│ └── save.js
+└── functions.php
+```
+
+### Theme Blocks Class
+
+```php
+ Array of paths to the blocks directories.
+ */
+ public function get_blocks_directory(): array {
+ return [
+ get_template_directory() . '/blocks/',
+ ];
+ }
+}
+```
+
+### Block Definition (block.json)
+
+```json
+{
+ "name": "your-theme/hero",
+ "title": "Hero Block",
+ "description": "A hero section block",
+ "category": "layout",
+ "icon": "cover-image",
+ "keywords": ["hero", "banner", "header"],
+ "supports": {
+ "align": ["wide", "full"],
+ "color": {
+ "background": true,
+ "text": true
+ }
+ },
+ "attributes": {
+ "title": {
+ "type": "string",
+ "default": "Welcome"
+ },
+ "subtitle": {
+ "type": "string",
+ "default": "Subtitle text"
+ }
+ },
+ "editorScript": "file:./build/index.js",
+ "editorStyle": "file:./build/editor.css",
+ "style": "file:./build/style.css"
+}
+```
+
+## Plugin Implementation
+
+### Directory Structure
+
+```
+your-plugin/
+├── src/
+│ └── Blocks.php
+├── blocks/
+│ ├── contact-form/
+│ │ ├── block.json
+│ │ ├── edit.js
+│ │ ├── index.js

+│ └── testimonials/
+│ ├── block.json
+│ ├── edit.js
+│ ├── index.js

+│ └── save.js
+└── plugin.php
+```
+
+### Plugin Blocks Class
+
+```php
+ Array of paths to the blocks directories.
+ */
+ public function get_blocks_directory(): array {
+ return [
+ plugin_dir_path( __FILE__ ) . 'blocks/',
+ ];
+ }
+}
+```
+
+## Multiple Directories
+
+You can register blocks from multiple directories:
+
+```php
+public function get_blocks_directory(): array {
+ return [
+ get_template_directory() . '/blocks/', // Theme blocks
+ get_template_directory() . '/custom-blocks/', // Custom theme blocks
+ plugin_dir_path( __FILE__ ) . 'vendor-blocks/', // Third-party blocks
+ ];
+}
+```
+
+## Block Structure
+
+### Required Files
+
+Each block directory must contain:
+
+- **`block.json`** - Block metadata (required)
+- **`index.js`** - Block JavaScript (required)
+
+### Standard Files (Recommended)
+
+- **`edit.js`** - Editor component (recommended)
+- **`save.js`** - Save component (recommended)
+- **`markup.php`** - Server-side rendering (recommended for dynamic blocks)
+
+### Optional Files
+
+- **`style.css`** - Block styles
+- **`editor.css`** - Editor-only styles
+
+### Dynamic Blocks with Server-Side Rendering
+
+For blocks that need server-side rendering, add a `markup.php` file:
+
+```php
+
+
+
+```
+
+The `BlockRegistrar` automatically detects `markup.php` files and creates render callbacks.
+
+## Advanced Features
+
+### Conflict Detection
+
+The `BlockRegistrar` automatically detects block name conflicts between themes and plugins:
+
+```php
+// Check if a block has conflicts
+if ( \TenupFramework\BlockRegistrar::has_block_conflict( 'theme/hero' ) ) {
+ $source = \TenupFramework\BlockRegistrar::get_block_source( 'theme/hero' );
+ error_log( "Block 'theme/hero' already registered by: {$source}" );
+}
+
+// Get all registered blocks and their sources
+$sources = \TenupFramework\BlockRegistrar::get_all_block_sources();
+foreach ( $sources as $block_name => $source_class ) {
+ echo "Block '{$block_name}' registered by: {$source_class}\n";
+}
+```
+
+### Error Handling
+
+The `BlockRegistrar` provides comprehensive error handling:
+
+- **Invalid directories** - Skipped with error logging
+- **Malformed JSON** - Skipped with error logging
+- **Missing required fields** - Skipped with error logging
+- **Block registration failures** - Logged with details
+
+### Security Features
+
+- **Path validation** - Prevents directory traversal attacks
+- **JSON validation** - Ensures proper block metadata
+- **File permission checks** - Verifies readable directories
+- **Block name validation** - Enforces proper naming conventions
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Blocks Not Appearing
+
+**Problem**: Blocks don't appear in the editor.
+
+**Solutions**:
+- Check that `block.json` exists and is valid JSON
+- Verify the block name follows `namespace/name` format
+- Ensure the directory path is correct
+- Check WordPress error logs for registration errors
+
+#### 2. Block Name Conflicts
+
+**Problem**: "Block name conflict detected" error.
+
+**Solutions**:
+- Use unique block names (e.g., `theme/hero`, `plugin/form`)
+- Check which class registered the conflicting block
+- Consider using different namespaces
+
+#### 3. Server-Side Rendering Not Working
+
+**Problem**: Dynamic blocks don't render on the frontend.
+
+**Solutions**:
+- Ensure `markup.php` exists in the block directory
+- Check that `markup.php` has proper PHP syntax
+- Verify the block is registered as dynamic in `block.json`
+
+#### 4. Styles Not Loading
+
+**Problem**: Block styles don't appear.
+
+**Solutions**:
+- Check `style.css` path in `block.json`
+- Ensure the CSS file exists
+- Verify the `style` property is correctly set
+
+### Debug Information
+
+Enable WordPress debug logging to see detailed error messages:
+
+```php
+// In wp-config.php
+define( 'WP_DEBUG', true );
+define( 'WP_DEBUG_LOG', true );
+```
+
+Check `/wp-content/debug.log` for `BlockRegistrar` error messages.
+
+### Testing Your Implementation
+
+```php
+// Test that your blocks class is working
+$blocks = new YourTheme\Blocks();
+$directories = $blocks->get_blocks_directory();
+
+// Check if directories exist
+foreach ( $directories as $dir ) {
+ if ( ! file_exists( $dir ) ) {
+ error_log( "Block directory does not exist: {$dir}" );
+ }
+}
+```
+
+## Best Practices
+
+1. **Use descriptive block names** - `theme/hero` instead of `theme/block1`
+2. **Organize blocks logically** - Group related blocks in subdirectories
+3. **Include proper metadata** - Complete `block.json` with all required fields
+4. **Test thoroughly** - Verify blocks work in both editor and frontend
+5. **Handle errors gracefully** - Check error logs regularly
+6. **Use consistent naming** - Follow your project's naming conventions
