# 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
|
||||
