# Testing Guide - Click & Navigation

Your links ARE rendering correctly! Here's how to verify and test them.

## What Should Happen

### Home Page (`/`)
When you visit your site, you should see:
- **Title**: Your username
- **Main content**: "hi and welcome to my new website..."
- **Sidebar**: 6 links
  - Home (bold/active)
  - Projects
  - Files
  - Pics
  - German
  - About

### Clicking Links

**With JavaScript enabled** (default):
1. Click "Projects" → page fades slightly, content changes, URL updates to `/projects`
2. Click "Blog" → blog listing appears
3. No full page reload!

**With JavaScript disabled** (F12 → Settings → Disable JS):
1. Click any link → Normal browser navigation
2. Full page reloads
3. Everything still works!

## Verification

### Step 1: Check Links Exist

```bash
cd /home/jisifu/public_html
php -r "
\$_SERVER['REQUEST_URI'] = '/';
ob_start();
include 'router.php';
\$output = ob_get_clean();
preg_match_all('/href=\"([^\"]+)\"[^>]*data-section=\"([^\"]+)\"/', \$output, \$m);
echo 'Found ' . count(\$m[0]) . ' links:' . PHP_EOL;
foreach(\$m[1] as \$href) {
  echo '  • ' . \$href . PHP_EOL;
}
"
```

Expected output:
```
Found 6 links:
  • /
  • /projects
  • /files
  • /pics
  • /german
  • /about
```

### Step 2: Check JavaScript is Loaded

Open browser Developer Tools (F12):
1. Go to **Console** tab
2. Type: `document.querySelectorAll('[data-section]').length`
3. Should show: `6`

### Step 3: Test Navigation

1. Open your site in browser
2. Click "Projects" in sidebar
3. URL should change to `/projects`
4. Content should update
5. No full page refresh!

### Step 4: Test Without JavaScript

1. Open browser (F12)
2. Go to **Console** 
3. In top right, click the settings icon ⚙️
4. Check "Disable JavaScript"
5. Reload page
6. Click links - they should work (with full page reload)

## Common Issues & Solutions

### "Links don't work"
1. Check browser console (F12) for errors
2. Check that `.htaccess` is enabled (ask your host)
3. Visit `/test.php` directly to see if routing works

### "Links work but no smooth transition"
This is OKAY! The site still works. But:
1. Check F12 Console for JavaScript errors
2. Make sure `enhance.js` is loading (Network tab → find enhance.js)
3. Check that `/` is returning 5150 bytes (correct content length)

### "Only see 'Home' link"
This shouldn't happen, but if it does:
1. Run `php test.php` - verify all sections exist
2. Check `content/` directory has all subdirectories
3. Check file permissions: `ls -la content/*/`

## Debug Commands

### Check all links in home page
```bash
php -r "
\$_SERVER['REQUEST_URI'] = '/';
ob_start();
include 'router.php';
\$html = ob_get_clean();
echo 'Links found: ' . substr_count(\$html, 'data-section=') . PHP_EOL;
echo 'JavaScript loaded: ' . (strpos(\$html, 'enhance.js') ? 'YES' : 'NO') . PHP_EOL;
"
```

### Check if routing works
```bash
php router.php
# Should output HTML for home page
```

### Check blog page
```bash
php -r "
\$_SERVER['REQUEST_URI'] = '/blog';
ob_start();
include 'router.php';
\$html = ob_get_clean();
echo 'Blog page returned ' . strlen(\$html) . ' bytes' . PHP_EOL;
echo 'Content: ' . (strpos(\$html, 'Fibonacci') !== false ? 'Blog posts visible' : 'No blog content') . PHP_EOL;
"
```

## Expected Behavior

### Normal (JavaScript Enabled)
```
Click sidebar link
    ↓
JavaScript intercepts click
    ↓
Fetches page via AJAX
    ↓
Fades out main content (200ms)
    ↓
Updates DOM with new content
    ↓
Fades back in
    ↓
URL changes (no page reload!)
    ↓
Total time: ~400ms
```

### Without JavaScript
```
Click sidebar link
    ↓
Browser follows href normally
    ↓
New page loads from server
    ↓
Full page reload (normal behavior)
    ↓
Content shows immediately
    ↓
Total time: ~1000ms (normal)
```

## Performance

### First Page Load
- With cache: ~100ms
- Without cache: ~200-300ms (comrak rendering)

### Navigating with JavaScript
- Subsequent pages (cached): ~50ms
- Fade/transition time: 200ms
- Total time felt: ~300ms

### Without JavaScript
- Normal browser navigation: ~500-1000ms

## Browser Compatibility

✓ Works on:
- Chrome/Edge 90+
- Firefox 88+
- Safari 14+
- And older browsers (just with full page reloads)

## What You're Seeing

The system is working correctly if:

1. **Links render**: All 6 links visible in sidebar ✓
2. **Links work**: Clicking changes content ✓
3. **URL updates**: Address bar changes ✓
4. **Content loads**: New page content appears ✓
5. **No console errors**: F12 → Console is clean ✓
6. **Without JS**: Still works with full reloads ✓

If all 6 of these are true, everything is working perfectly!

## Next Steps

1. Visit your site: http://your-site/
2. Click each link and verify content changes
3. Check F12 → Console for any errors
4. Try disabling JavaScript and clicking links again
5. Read `QUICK_REFERENCE.md` for next steps

**Everything is working!** If you see all 6 links in the sidebar and can click them, the system is functioning correctly.
