## Description

**Auto SKU Generator** takes the hassle out of creating SKUs for your WooCommerce
products. Instead of manually typing a SKU for every product, this plugin automatically
generates structured, unique SKUs based on your product’s category and ID.

#### How It Works

When you create or save a WooCommerce product without a SKU, Auto SKU Generator 
automatically assigns one using a consistent format:

**[Prefix][Product ID][Suffix]**

 * The **prefix** is derived from the product’s category ID (zero-padded to 3 digits)
   or a custom prefix you define per category.
 * The **product ID** portion is zero-padded to fill the remaining SKU length.
 * A trailing digit is appended to ensure uniqueness in case of collisions.

#### Features

 * **Automatic SKU assignment** — Products saved without a SKU get one automatically.
 * **Two prefix modes** — Use the category ID as a prefix, or define your own custom
   prefix for each category.
 * **Configurable SKU length** — Set your preferred total SKU length between 8 and
   20 characters.
 * **Live SKU preview** — A suggested SKU appears below the SKU field on the product
   edit screen, updating in real time as you change categories.
 * **Click-to-insert** — Click the suggested SKU to instantly populate the SKU field.
 * **Collision handling** — If a generated SKU already exists, the plugin automatically
   tries alternative suffixes.
 * **Settings page** — Configure everything from Products > Auto SKU Generator in
   your WordPress admin.
 * **Clean uninstall** — All plugin data is removed when you delete the plugin.

#### Use Cases

 * Online stores with large product catalogs that need consistent SKU formatting.
 * Shops where multiple team members add products and you want standardized SKUs.
 * Stores migrating from another platform that need to establish a new SKU system.
 * Any WooCommerce store that wants to save time on manual SKU entry.

#### Requirements

 * WordPress 5.6 or higher
 * WooCommerce 5.0 or higher
 * PHP 7.4 or higher

## Installation

 1. Upload the `auto-sku-generator` folder to the `/wp-content/plugins/` directory,
    or install the plugin through the WordPress Plugins screen.
 2. Activate the plugin through the ‘Plugins’ screen in WordPress.
 3. Go to **Products > Auto SKU Generator** to configure your settings.
 4. Choose your prefix mode (Category ID or User-Defined) and set your preferred SKU
    length.
 5. Start creating products — SKUs will be generated automatically!

## FAQ

### Does this plugin require WooCommerce?

Yes. Auto SKU Generator is built specifically for WooCommerce and requires WooCommerce
5.0 or higher to function.

### Will it overwrite my existing SKUs?

No. The plugin only generates a SKU when a product is saved without one. If a product
already has a SKU, it is left untouched.

### What happens if the generated SKU already exists?

The plugin automatically appends a different trailing digit (0-9) to find a unique
SKU. This prevents duplicate SKU errors.

### Can I use my own custom prefixes instead of category IDs?

Yes. On the settings page (Products > Auto SKU Generator), switch to “User-Defined
Prefixes” mode and enter a custom alphanumeric prefix for each product category.

### What format are the generated SKUs?

SKUs follow the pattern: [Prefix][Zero-padded Product ID][Suffix digit]. For example,
with category ID mode and a SKU length of 13, product ID 42 in category 5 would 
get a SKU like `005000000420`.

### Can I change the SKU length?

Yes. You can set the total SKU length anywhere from 8 to 20 characters on the settings
page.

### What happens when I delete the plugin?

All plugin settings are removed from your database. Your product SKUs remain unchanged
since they are part of the product data, not the plugin settings.

### Does it work with variable products?

The plugin generates SKUs for the parent product. Variation SKUs are managed through
WooCommerce’s built-in variation system.

### Is the plugin compatible with the block editor?

Yes. The plugin works with both the classic WooCommerce product editor and the block-
based product editor.
