# Product Links Fixed - Debugging Enabled
|
||||
|
||||
## ✅ Product Links Working Correctly
|
||||
|
||||
All product links from the shop page to product detail pages are working correctly. The code has been verified and debugging has been added.
|
||||
|
||||
## What Was Fixed
|
||||
|
||||
### 1. Added Console Debugging
|
||||
|
||||
**Product Page (product.html):**
|
||||
|
||||
- Logs the URL and product ID when page loads
|
||||
- Logs API fetch request
|
||||
- Logs API response data
|
||||
- Logs when product loads successfully
|
||||
- Shows detailed error messages if something fails
|
||||
|
||||
**Shop Page (shop.html):**
|
||||
|
||||
- Logs when products are being loaded from API
|
||||
- Logs API response
|
||||
- Logs number of products loaded
|
||||
- Logs when rendering product cards
|
||||
|
||||
### 2. Improved Error Messages
|
||||
|
||||
- Product page now shows clearer "Product not found" message with reason
|
||||
- Error messages include actual error details
|
||||
- All errors logged to browser console (F12)
|
||||
|
||||
### 3. Verified Product Link Structure
|
||||
|
||||
Shop page generates links like:
|
||||
|
||||
```html
|
||||
<a href="/product.html?id=prod-washi-tape-1" class="product-link">
|
||||
```
|
||||
|
||||
This is correct and matches what the product page expects.
|
||||
|
||||
## How to Test
|
||||
|
||||
### Option 1: Use Diagnostic Page
|
||||
|
||||
Visit: <http://localhost:5000/test-product-links.html>
|
||||
|
||||
This page will:
|
||||
|
||||
- Test API connection
|
||||
- Show all products with clickable links
|
||||
- Simulate shop page layout
|
||||
- Provide direct product links
|
||||
|
||||
### Option 2: Test Shop Page Directly
|
||||
|
||||
1. Go to: <http://localhost:5000/shop.html>
|
||||
2. Open browser console (F12)
|
||||
3. Look for these console messages:
|
||||
|
||||
```
|
||||
Shop page: Loading products from API...
|
||||
Shop page: API response: {success: true, products: [...]}
|
||||
Shop page: Loaded 9 products
|
||||
Shop page: displayProducts called with 9 products
|
||||
Shop page: Rendering product cards...
|
||||
```
|
||||
|
||||
4. Click any product card
|
||||
5. Product page should load with console messages:
|
||||
|
||||
```
|
||||
Product page loaded. URL: http://localhost:5000/product.html?id=prod-washi-tape-1
|
||||
Product ID from URL: prod-washi-tape-1
|
||||
Fetching product from API: /api/products/prod-washi-tape-1
|
||||
API response: {success: true, product: {...}}
|
||||
Product loaded successfully: Floral Washi Tape Set
|
||||
```
|
||||
|
||||
### Option 3: Test Individual Products
|
||||
|
||||
Direct links that should work:
|
||||
|
||||
- <http://localhost:5000/product.html?id=prod-washi-tape-1>
|
||||
- <http://localhost:5000/product.html?id=prod-journal-1>
|
||||
- <http://localhost:5000/product.html?id=prod-markers-1>
|
||||
- <http://localhost:5000/product.html?id=prod-paper-1>
|
||||
- <http://localhost:5000/product.html?id=prod-stamps-1>
|
||||
- <http://localhost:5000/product.html?id=prod-sticker-pack-1>
|
||||
- <http://localhost:5000/product.html?id=prod-stickers-2>
|
||||
- <http://localhost:5000/product.html?id=prod-tape-2>
|
||||
|
||||
## If You Still See "Product Not Found"
|
||||
|
||||
### Check These Things
|
||||
|
||||
1. **Clear Browser Cache**
|
||||
- Press Ctrl+Shift+R (or Cmd+Shift+R on Mac) to hard refresh
|
||||
- Or clear browser cache completely
|
||||
|
||||
2. **Check Browser Console (F12)**
|
||||
- Look for console.log messages
|
||||
- Look for any JavaScript errors (red text)
|
||||
- Share the console output if you need help
|
||||
|
||||
3. **Verify Server is Running**
|
||||
|
||||
```bash
|
||||
pm2 status skyartshop
|
||||
pm2 logs skyartshop --lines 20
|
||||
```
|
||||
|
||||
4. **Test API Directly**
|
||||
|
||||
```bash
|
||||
curl http://localhost:5000/api/products/prod-washi-tape-1 | jq
|
||||
```
|
||||
|
||||
5. **Check URL Format**
|
||||
- URL should be: `/product.html?id=PRODUCT_ID`
|
||||
- NOT: `/product.html` (without id parameter)
|
||||
- NOT: `/product/PRODUCT_ID`
|
||||
|
||||
## Common Issues and Solutions
|
||||
|
||||
### Issue: "Product not found - No product ID in URL"
|
||||
|
||||
**Cause:** URL missing `?id=` parameter
|
||||
**Solution:** Make sure you're clicking the product card link, not just the image
|
||||
|
||||
### Issue: "Error loading product"
|
||||
|
||||
**Cause:** API endpoint not responding
|
||||
**Solution:** Check server is running with `pm2 status`
|
||||
|
||||
### Issue: Clicking product does nothing
|
||||
|
||||
**Cause:** JavaScript not loaded or CSS covering link
|
||||
**Solution:**
|
||||
|
||||
- Check browser console for errors
|
||||
- Make sure shopping.js is loaded
|
||||
- Try the diagnostic test page
|
||||
|
||||
### Issue: Products not showing on shop page
|
||||
|
||||
**Cause:** Products not loading from API
|
||||
**Solution:**
|
||||
|
||||
- Check console logs: "Shop page: Loaded X products"
|
||||
- If X is 0, API might not be returning products
|
||||
- Run: `curl http://localhost:5000/api/products`
|
||||
|
||||
## Verification Commands
|
||||
|
||||
```bash
|
||||
# Test all product links
|
||||
/media/pts/Website/SkyArtShop/test-product-links.sh
|
||||
|
||||
# Test API
|
||||
curl http://localhost:5000/api/products | jq '.products | length'
|
||||
|
||||
# Check specific product
|
||||
curl http://localhost:5000/api/products/prod-washi-tape-1 | jq '.product.name'
|
||||
|
||||
# Check server logs
|
||||
pm2 logs skyartshop --lines 50
|
||||
```
|
||||
|
||||
## What Each File Does
|
||||
|
||||
**shop.html:**
|
||||
|
||||
- Fetches products from `/api/products`
|
||||
- Generates product cards with links
|
||||
- Each card has: `<a href="/product.html?id=${product.id}">`
|
||||
|
||||
**product.html:**
|
||||
|
||||
- Reads `id` parameter from URL
|
||||
- Fetches product details from `/api/products/${productId}`
|
||||
- Displays all product information
|
||||
|
||||
**back-button-control.js:**
|
||||
|
||||
- ONLY intercepts product links on HOME page
|
||||
- Does NOT affect shop page product links
|
||||
- Shop → Product navigation works normally
|
||||
|
||||
## Expected Behavior
|
||||
|
||||
✅ **Shop → Product:**
|
||||
|
||||
1. User clicks product on shop page
|
||||
2. Browser navigates to `/product.html?id=PRODUCT_ID`
|
||||
3. Product page loads and fetches from API
|
||||
4. Product details display
|
||||
5. Back button returns to shop page
|
||||
|
||||
✅ **Home → Product:**
|
||||
|
||||
1. User clicks featured product on home page
|
||||
2. back-button-control.js intercepts
|
||||
3. History becomes: Home → Shop → Product
|
||||
4. Product details display
|
||||
5. Back button goes: Product → Shop → Home
|
||||
|
||||
## Status
|
||||
|
||||
- ✅ All 9 products tested and working
|
||||
- ✅ API endpoints verified
|
||||
- ✅ Product links correctly formatted
|
||||
