WordPress Shortcode & Image Handling Fix - Complete Summary

Overview

Successfully enhanced the ContentRenderer and html-compat.ts to properly handle WordPress shortcodes and ensure all images display correctly with Next.js Image optimization.

Completed Tasks

1. Enhanced Shortcode Processing in lib/html-compat.ts

Added comprehensive shortcode conversion functions:

  • processVcRowShortcodes() - Converts [vc_row] to flex containers with background support
  • processVcColumnShortcodes() - Converts [vc_column] to responsive width classes
  • processVcColumnTextShortcodes() - Converts [vc_column_text] to prose styling
  • processVcImageShortcodes() - Converts [vc_single_image] to img tags with data attributes
  • processVcButtonShortcodes() - Converts [vc_btn] to styled buttons
  • processVcSeparatorShortcodes() - Converts [vc_separator] to HR elements
  • processVcVideoShortcodes() - Converts [vc_video] to video elements
  • processBackgroundShortcodes() - Handles background image/video attributes

Key Features:

  • Parses shortcode attributes (bg_image, bg_color, color_overlay, etc.)
  • Converts to Tailwind classes and inline styles
  • Handles complex attributes like gradients, overlays, and video backgrounds
  • Supports Salient/Visual Composer specific attributes

2. Enhanced ContentRenderer in components/content/ContentRenderer.tsx

Updated image handling:

  • Uses getMediaById() and getMediaByUrl() from data layer
  • Converts WordPress image IDs to local paths
  • Properly dimensions images using media metadata
  • Uses Next.js Image component with optimization
  • Handles external images with regular img tags

Enhanced HTML parsing:

  • Added parseStyleString() helper for inline styles
  • Support for video elements with sources
  • Background image/video handling with data attributes
  • Color overlay support with opacity
  • Parallax background support
  • Style prop conversion from string to object

Safe element rendering:

  • Only allows safe HTML tags and attributes
  • Uses Next.js Link for internal links
  • External links open in new tabs with security attributes
  • Proper error handling for missing media

3. Integration with Data Layer

Image URL replacement:

  • Uses getAssetMap() for bulk URL replacement
  • Falls back to getMediaByUrl() for individual images
  • Handles both full URLs and relative paths
  • Supports WordPress upload directory structure

4. Test Page Creation

Created comprehensive test page:

  • app/[locale]/example/components-demo/page.tsx
  • Tests all shortcode types
  • Tests image handling with real media IDs
  • Tests background images and overlays
  • Tests button styles and layouts
  • Tests typography and spacing

🎯 WordPress Shortcodes Now Supported

Layout Shortcodes

  • [vc_row]<div class="flex flex-wrap -mx-4">
  • [vc_column width="6"]<div class="w-full md:w-1/2 px-4">
  • [vc_column_text]<div class="prose max-w-none">

Background & Styling

  • bg_image="1234" → Background image from media library
  • bg_color="#ffffff" → Background color
  • color_overlay="#000000" → Dark overlay with opacity
  • enable_gradient="true" → Gradient backgrounds
  • top_padding="4%" → Padding styles

Content Elements

  • [vc_btn color="primary" title="Click" link="#"] → Styled buttons
  • [vc_single_image src="1234" align="center"] → Next.js Image
  • [vc_separator color="primary"] → Styled HR
  • [vc_video mp4="url" webm="url"] → Video backgrounds

Image Handling

  • WordPress media IDs → local paths
  • Automatic dimensions from metadata
  • Next.js Image optimization
  • Alignment (left, right, center)
  • Sizing (thumbnail, medium, large, full)

🔧 Technical Implementation Details

Shortcode Processing Flow

  1. Input: WordPress HTML with shortcodes
  2. processHTML(): Calls enhanced shortcode processor
  3. Shortcode conversion: Converts to HTML with data attributes
  4. Asset replacement: URLs → local paths
  5. Class conversion: WordPress → Tailwind classes
  6. HTML parsing: Safe React element creation
  7. Output: Clean React components

Image Processing Flow

  1. Detect: data-wp-image-id or src attributes
  2. Lookup: getMediaById() or getMediaByUrl()
  3. Extract: localPath, width, height, alt
  4. Render: Next.js Image with proper props
  5. Fallback: Regular img for external URLs

Background Processing

  1. Data attributes: data-bg-image, data-video-bg
  2. Style generation: Inline styles for backgrounds
  3. Overlay handling: Absolute positioned overlay divs
  4. Video backgrounds: Auto-playing muted videos
  5. Parallax: CSS classes for scroll effects
