# Critical Fixes Applied - January 2, 2026

## Issues Fixed

### 1. SQL Syntax Error in getFeaturedStores()
**Error:** `SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax near ''10''`

**Root Cause:** PDO cannot bind LIMIT values with named parameters (`:limit`) in some MySQL/MariaDB versions.

**Fix Applied:**
- Changed from: `LIMIT :limit` with `$sentence->execute(array(':limit' => (int)$limit));`
- Changed to: `LIMIT $limit` with direct integer interpolation after casting
- File: `functions.php` line 526-529

**Code Change:**
```php
// OLD (broken):
$sentence = $connect->prepare("... LIMIT :limit");
$sentence->execute(array(':limit' => (int)$limit));

// NEW (fixed):
$limit = (int)$limit; // Cast to int for security
$sentence = $connect->prepare("... LIMIT $limit");
$sentence->execute();
```

### 2. Missing getCssUrl() Function
**Error:** `getCssUrl() missing`

**Root Cause:** Function was defined in `views/includes/header-css.php` but called before that file was included in the page load sequence.

**Fix Applied:**
- Moved `getCssUrl()` function from `views/includes/header-css.php` to `functions.php` (after getImageUrl function)
- Function is now globally available since functions.php is loaded early via core.php
- Files modified:
  - `functions.php` - Added getCssUrl() function around line 1380
  - `views/includes/header-css.php` - Removed function definition, added comment

**Code Added to functions.php:**
```php
/**
 * Get CSS URL - returns CDN URL if configured, otherwise local CSS path
 * @param string $filename - CSS filename
 * @return string - Full CSS URL or path
 */
function getCssUrl($filename) {
    global $urlPath;
    
    // CDN URL is disabled by default
    $cdn_css_url = '';
    
    if (!empty($cdn_css_url)) {
        return $cdn_css_url . '/' . $filename;
    }
    
    return $urlPath->assets_css($filename);
}
```

## Related Files

### Modified Files:
- `functions.php` - Fixed SQL LIMIT binding, added getCssUrl()
- `views/includes/header-css.php` - Removed getCssUrl() function definition
- `test_fixes.php` - Created for testing

### Previous Fixes (Still Active):
- `views/includes/footer-js.php` - Set `$cdn_js_url = ''` (local JS)
- `views/header.view.php` - Added fallback preloader removal script
- All frontend views - Updated to use getImageUrl() for CDN support

## Troubleshooting

### If Homepage Still Shows Errors:

1. **Check Database CDN Fields:**
   ```sql
   -- Run this SQL to add CDN fields if missing:
   -- File: admin/sql/add_all_cdn_fields.sql
   
   ALTER TABLE stores 
   ADD COLUMN store_image_cdn_url VARCHAR(500) DEFAULT NULL,
   ADD COLUMN store_use_cdn TINYINT(1) DEFAULT 0;
   ```

2. **Clear All Caches:**
   - Browser cache: Ctrl+Shift+Delete
   - Server cache: Visit `clear_server_cache.php`
   - Hard refresh: Ctrl+F5

3. **Check PHP Errors:**
   - Visit: `show_errors.php` or `test_errors.php`
   - Enable errors in `.htaccess` or `php.ini`

4. **Verify JS Loading:**
   - Open browser console (F12)
   - Check if `main.js` loads without 404 errors
   - Should be from: `www.alonedeals.com/assets/js/main.js`

### If Preloader Still Spinning:

The fallback script in `views/header.view.php` should remove it after 5 seconds maximum. If it persists:
- Check browser console for JavaScript errors
- Verify `main.js` is loading (not 404)
- Try disabling browser extensions
- Clear browser cache completely

### If Footer Not Showing:

- Check for PHP errors above footer (use `show_errors.php`)
- Verify `footer-js.php` has `$cdn_js_url = ''`
- Check that `sections/views/footer.view.php` exists
- Look for unclosed HTML tags in page content

## Summary

Both critical issues have been resolved:
1. ✓ SQL LIMIT binding fixed - no more syntax errors
2. ✓ getCssUrl() function now globally available

The site should now load correctly with:
- Featured stores displaying on homepage
- All CSS loading from local server
- Preloader disappearing automatically
- Footer rendering properly
