Interactive Walkthroughs is a custom WordPress plugin that lets non-technical users build and publish guided product, service, or software walkthroughs directly from the WordPress admin. Instead of hard-coding every demo page, an admin can create a walkthrough, add ordered stages, attach screenshots or videos, write step-by-step guidance, and embed the finished experience anywhere on the site with a shortcode.

[SCREENSHOT 1: Front-end walkthrough full view]
Show the complete published walkthrough on the front end. This should communicate the final user-facing experience: stage rail, main media area, guidance panel, and navigation controls.

The goal of the plugin was to turn static screenshots into reusable presentation-ready demo assets. This is especially useful for agencies, business owners, sales teams, and content editors who need to explain a process visually without rebuilding pages manually every time.

The plugin creates a dedicated Walkthroughs custom post type inside WordPress. Each walkthrough is managed as its own content object, making it easy to create, edit, reuse, and embed guided demos across different pages.

[SCREENSHOT 2: WordPress admin Walkthroughs CPT list]
Show the Walkthroughs area in wp-admin so the viewer immediately understands this is a real CMS-managed plugin, not a static front-end mockup.

Inside the walkthrough editor, users can build multiple stages. Each stage can include a title, short rail summary, headline, supporting copy, trigger, what the user sees, action, rule, verification notes, audience label, clone route, screen name, and media. This gives the editor a structured way to explain both the visual screen and the business logic behind each step.

[SCREENSHOT 3: Admin stage builder]
Show the stage builder interface with several fields visible. This is one of the strongest proof screenshots because it shows the admin workflow and structured data entry.

For media, each stage supports images, uploaded videos, embedded videos, poster images, and captions. The front end only displays media controls when valid media exists, keeping the presentation clean and preventing broken or empty interface states.

[SCREENSHOT 4: Media display with screenshot/video toggle]
Show a stage with a screenshot or video displayed in the front-end canvas. If both image and video exist, show the media toggle to prove conditional front-end behavior.

Technically, the plugin uses JSON-based post meta to store nested stage and settings data. The data is normalized through sanitization helpers before saving, including stage IDs, ordering, URLs, audience values, media IDs, video modes, default media views, and fallback values. This keeps the saved data predictable even when users enter incomplete or invalid information.

The front-end experience is powered by a shortcode: . When placed on any WordPress page, the shortcode renders the walkthrough shell and loads the front-end app. The app retrieves a normalized walkthrough payload from a custom REST endpoint instead of reading raw post meta directly.

[SCREENSHOT 5: Shortcode placed inside a WordPress page]
Show the shortcode inserted into a page editor. This connects the full workflow: admin builds walkthrough → shortcode embeds it → front end renders the experience.

The front-end includes a three-column presentation layout with a stage rail, sticky presenter bar, main media canvas, and right-side guidance panel. Users can move through stages using clickable navigation, previous/next controls, URL hash navigation, and keyboard shortcuts such as Left, Right, Home, and End.

[SCREENSHOT 6: Stage navigation / rail]
Show the left rail or stage navigation in action. This proves the walkthrough is interactive and stage-based, not just a single static content block.

The plugin also includes QA-focused behavior for missing media, invalid URLs, disabled clone links, embedded video handling, hash syncing, and keyboard navigation. These details make the project stronger because they show attention to real-world edge cases, not just happy-path functionality.

Technical Highlights

• Registered a custom WordPress post type for reusable walkthrough objects.
• Built an admin stage builder for creating ordered walkthrough steps.
• Stored nested stage and settings data as normalized JSON meta.
• Added sanitization helpers for IDs, order, URLs, enum values, booleans, media IDs, and fallback defaults.
• Created a REST endpoint for serving a clean front-end walkthrough payload.
• Built a shortcode renderer for embedding walkthroughs on any WordPress page.
• Added front-end stage navigation, media display, keyboard navigation, and URL hash syncing.
• Supported images, uploaded videos, embedded videos, poster images, captions, and conditional media controls.
• Included QA handling for missing media, empty stages, invalid clone routes, and disabled controls.

Business Value

Interactive Walkthroughs helps businesses turn complex services, product flows, or software demos into clear visual presentations. Instead of needing a developer to hard-code each walkthrough, a site admin can create and update demos directly inside WordPress. That makes the plugin useful for sales enablement, onboarding, product education, service explainers, internal training, and client presentations.

Developer Takeaway

This project demonstrates real WordPress plugin architecture: custom post types, admin UI, structured meta storage, sanitization, REST payload design, shortcode rendering, asset loading, front-end interaction, media handling, and QA thinking. It shows the ability to build a practical CMS tool that connects backend content management with a polished front-end user experience.
