Intended for use by Woocommerce shop admin who manage a shop with no pre-defined catalog number for the products. Adds button to the prod. edit page.

== Description ==

When adding or editing a product it is common that you do not have a pre-set catalog number for the product. 
The button enables you to add random SKU (catalog number) to the product, with specified format and length. 
It also checks that the suggested SKU does not exist in the product list at your Woocommerce shop. 
At the same time you can use it to check a SKU number you enter.
Starting on V 1.0.1 you can choose to add automatic SKU for every new product or existing product without a SKU (no need to click a button or select).

ATR Random sku for Woocommerce plugin is intended for use by Woocommerce shop administrators that manage a shop with no pre-defined catalog number for the products.
If you do not have a pre-defined catalog number for the products you upload to the shop, you must be wasting time on each product’s sku that you have to come up with.

In that case you have to come up with a new sku string and you probably want it to have a pre-defined format. You surely want a unique sku number.

That takes time and is susceptible to errors.

The plugin deals exactly with this issue. It adds a button to the Edit or New product page, that by clicking on it you get a random sku string and insert it to the product’s sku textbox.
You also can select not to generate a random sku, but write it yourself, and the plugin will check asynchronously if the sku already exist in the database.
This way you save the time of trying to save before you know if your sku is unique.

== Installation ==

Installing "ATR random sku for Woocommerce" can be done either by searching for "ATR random sku for Woocommerce" via the "Plugins > Add New" screen in your WordPress dashboard, 
or by using the following steps:

1. Upload the plugin files to the '/wp-content/plugins/atr-random-sku-for-woocommerce' directory, or install the plugin through the WordPress plugins screen directly.
1. Activate the plugin through the 'Plugins' screen in WordPress
1. Use the Settings->ATR All Menu Settings screen to configure the plugin
1. Select the format you require for the sku: "Use max min" or "Use string"
1. Set the relevant options for your selection
1. If you want the plugin to auto fill new products SKU for you select the option "Check this to fill auto SKU when field is empty (also for new products)"

= Settings =

The plugin options allows you to select between numeric and alpha numeric strings. The random sku format will be generated according to these selections.

=Numeric string ("Use max min")=
If you select a numeric string, you should set a minimum and maximum numbers.
Setting the min/max numbers will force the random sku generated to hold only numbers between those numbers.

That way you can also define how many digits will be in the sku.
For example, if you select min: 10000 and max: 99999 you’ll get sku’s with 5 digits long between these two numbers.

=Characters strings ("Use string")=
If you select a characters string, you’ll have to define

    The characters to be used in the string
    The length of the string

For example, if you select "abcdefghijklmnopqrstuvwxyz123456789" for the characters and "8" for the length, the sku string will be 8 characters long and with all the letters and numbers except 0 (zero) and capital letters.
