4WP Advanced Code extends WordPress’s native code block instead of replacing it. It adds syntax highlighting, a copy-to-clipboard button, deep-linking anchors, and SEO-friendly structured data — all without forcing you to re-enter your existing content.
Key capabilities
- Syntax highlighting via a bundled Highlight.js (no frontend CDN dependency), with automatic language detection
- Wraps the existing core Code block — no need to re-create content, and nothing breaks if the plugin is deactivated
- Dedicated Advanced Code block with per-block language and theme selection
- Copy-to-clipboard and share controls that run entirely in the visitor’s browser
- Anchor deep-linking for pointing directly at a specific code block
- SoftwareSourceCode JSON-LD structured data for search engines, togglable globally or per block
- Multiple visual themes — light, dark, terminal
- Broad language support — PHP, JavaScript, HTML/CSS, SCSS, Python, JSON, SQL, Bash, and more
- Performance-conscious loading — highlighting assets load only on pages that actually contain a code block
Pain points it solves
- No highlighting out of the box. WordPress’s native code block renders as plain, unstyled text — hard to read and easy to skim past.
- Search engines can’t parse raw snippets. Without structured data, code examples are invisible to code-aware search features.
- Existing highlighter plugins often replace core blocks. That creates lock-in: disable the plugin and your content breaks.
- No way to link to a specific snippet. Documentation and tutorials need shareable, deep-linkable anchors for individual code blocks.
- Privacy concerns with CDN-based highlighters. Copy and share actions run entirely in the visitor’s browser — nothing is sent to a third party.
Who it’s for
Developer blogs, technical documentation sites, plugin and theme developer portals, and agencies that want richer code presentation without abandoning the native block editor.
