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 + +## Examples + +### Complete Theme Example + +```php + + */ + public static array $registered_block_names = []; + + /** + * Static array to track block registration sources for conflict detection. + * + * @var array Block name => source class + */ + public static array $block_sources = []; + + /** + * Whether the allowed_block_types_all filter has been registered. + * + * @var bool + */ + public static bool $filter_registered = false; + + /** + * Get the blocks directory paths. + * + * @return array Array of paths to the blocks directories. + */ + abstract public function get_blocks_directory(): array; + + /** + * Can this module be registered? + * + * @return bool + */ + public function can_register(): bool { + return true; + } + + /** + * Register hooks. + * + * @return void + */ + public function register(): void { + add_action( 'init', [ $this, 'register_blocks' ], 10, 0 ); + } + + /** + * Automatically registers all blocks from the blocks directories. + * + * @return void + */ + public function register_blocks(): void { + // Check if WordPress and block editor are available + if ( ! function_exists( 'register_block_type_from_metadata' ) ) { + error_log( 'BlockRegistrar: WordPress block editor not available' ); // phpcs:ignore WordPress.PHP.DevelopmentFunctions.error_log_error_log + return; + } + + $blocks_dirs = $this->get_blocks_directory(); + $block_names = []; + $errors = []; + + foreach ( $blocks_dirs as $blocks_dir ) { + // Validate directory path + $validated_dir = $this->validate_directory_path( $blocks_dir ); + if ( ! $validated_dir ) { + $errors[] = "Invalid directory path: {$blocks_dir}"; + continue; + } + + if ( ! file_exists( $validated_dir ) ) { + continue; + } + + // Check if directory is readable + if ( ! is_readable( $validated_dir ) ) { + $errors[] = "Directory not readable: {$validated_dir}"; + continue; + } + + $block_json_files = glob( $validated_dir .
