Frequently Asked Questions
Common questions about Block Accessibility Checks
Once activated, navigate to Block Checks → Core Block Checks to configure your preferences Choose which checks should be errors (prevent publishing), warnings (allow publishing with notice), or disabled Start editing content in the Gutenberg editor - accessibility checks run automatically across blocks, meta fields, and document structure Blocks with issues will show red borders (errors) or yellow borders (warnings) with detailed messages in the block inspector panel Fix the highlighted issues or adjust check severity levels as needed
The plugin provides immediate visual feedback through its three-tier validation system: * Red borders and icons around blocks with critical accessibility errors * Yellow borders and icons around blocks with warnings * Detailed error messages in the block inspector sidebar panel, grouped by severity and category * Publishing prevention for critical errors in blocks, meta fields, or editor-level checks (configurable) * Warning indicators for less critical issues that still allow publishing with user awareness * Post locking when required meta fields fail validation
Yes! The plugin includes a comprehensive developer API with extensive hooks and filters. You can register custom accessibility checks for: Block validation - ba11yc_register_block_check() Meta field validation - ba11yc_register_meta_check() Editor-level validation - ba11yc_register_editor_check() Heading sources - ba11yc_register_heading_source() Register these on the ba11yc_ready action. See the developer documentation for complete examples and quick start guides.
Absolutely! Any WordPress block works, whether from core, themes, or third-party plugins. Their checks appear in the single Block Checks settings table, attributed and filterable by plugin, and headings they render count toward heading order validation.
Yes, all checks can be configured as errors (prevent publishing), warnings (allow publishing with notice), or disabled entirely. Visit Block Checks in your WordPress admin to access: Core block check settings Meta field check settings Site editor check settings External plugin check settings (automatically created)
Yes! Register required meta fields with ba11yc_register_meta_check() and implement the validation in JavaScript with the ba11yc.validateMeta filter. The plugin locks post saving when validation fails and surfaces the issues alongside block validation.
Yes! The plugin works in both the post editor and site editor. The site editor has separate configurable settings accessible at Block Checks → Site Editor Checks, allowing you to configure different validation rules for template/template part editing versus post-level content.
No, the plugin is optimized for performance with smart caching and efficient validation algorithms. All validation runs in JavaScript for real-time feedback without server round-trips. Checks run in real-time without impacting editor responsiveness.
Simply deactivate and delete the plugin through the WordPress admin interface.
