Usage

Adding Discounts

  1. Navigate to Nuolaidos in WordPress admin

    • CSV Upload: Upload a CSV file with SKU codes (one per line)
    • Category Selection: Select a product category from dropdown
  3. Enter discount percentage (1-100%)
  4. Set start and end dates (optional)
  5. Check "Skip products with existing discounts" if needed
  6. Check "Clear Cloudflare cache" if you have Cloudflare integration
  7. Click "Update Prices"

Viewing Discounted Products

  1. Navigate to Nuolaidos → Prekės su nuolaida
  2. View all products with active discounts
  3. Filter by category using the dropdown
  4. Use bulk actions to remove discounts from multiple products
  5. See discount schedules for each product

Removing Discounts

  1. Navigate to Nuolaidos → Ištrinti nuolaidas
  2. Choose one of three methods:
    • CSV Upload: Upload a CSV with SKUs to clear
    • Category Selection: Clear discounts from specific category
    • Clear All: Remove all discounts from all products
  3. Check "Clear Cloudflare cache" if needed
  4. Click "Update Prices"

SKU Tag Assignment

  1. Navigate to Nuolaidos → Priskirti TAG
  2. Choose method (CSV or Category)
  3. Select the tag to assign
  4. Click "Assign Product Tags"

CSV Format

CSV files should contain one SKU per line:

SKU001
SKU002
SKU003

Cloudflare Integration

If you have a Cloudflare plugin installed that provides a flush_cloudflare_cache() function, you can optionally purge the cache after discount operations by checking the "Clear Cloudflare cache" checkbox.

WPML Multilingual Support

The plugin includes full WPML compatibility for multilingual WooCommerce stores:

  • Automatic Detection: Detects WPML and identifies original language products
  • Cross-Language Sync: Applies discounts to all language versions automatically
  • One-Time Operation: Apply discounts once, works across all languages
  • Price Consistency: Ensures consistent pricing across English, Lithuanian, and all other languages

How It Works

When you apply a discount in any language (e.g., Lithuanian admin):

  1. Plugin finds the original language product (usually English)
  2. Retrieves all translation IDs (English, Lithuanian, German, etc.)
  3. Applies discount to ALL translations automatically
  4. Result: Consistent prices across all languages

No more manual work per language! See WPML-GUIDE.md for detailed documentation.

Batch Processing

For stores with thousands of products, the plugin includes intelligent batch processing:

  • Automatic Activation: Engages for 100+ products
  • Progress Tracking: Shows processing status and estimated time
  • No Timeouts: Handles 10,000+ products reliably
  • Server Friendly: Processes in batches of 50 with small pauses
  • Error Recovery: Continues processing even if individual products fail

Example: Processing 1,500 products across 3 languages (4,500 total operations) completes in ~90 seconds.

Filters and Hooks

The plugin uses standard WordPress and WooCommerce hooks. No custom filters are currently exposed, but you can extend the classes as needed.

Product Meta Fields

The plugin uses the following custom meta fields:

  • _nuolaida_pr: Stores the discount percentage
  • Standard WooCommerce fields: _sale_price, _sale_price_dates_from, _sale_price_dates_to

Security

  • All forms use WordPress nonces for CSRF protection
  • User capabilities are checked (requires manage_options)
  • All inputs are sanitized and escaped
  • SQL queries use prepared statements

Translation

The plugin is translation-ready with the text domain wc-discount-manager. Lithuanian translations are included by default.
