Native RUT field injection, Module 11 validation, and clean formatting for WooCommerce checkout in Chile.

Bloqcode Chile – RUT and Checkout Validation

Bloqcode Chile &#8211; RUT and Checkout Validation adapts the native WooCommerce checkout process to comply with standard customer identification requirements in Chile.
<h4>Important Compatibility Note</h4>
⚠️ This plugin is designed to work with the Classic WooCommerce Checkout (using the [woocommerce_checkout] shortcode).
If your store is using the newer WooCommerce Checkout Block, you will need to replace that block on your Checkout page with a Shortcode block containing: 
[woocommerce_checkout]
The plugin provides server-side and client-side validation to ensure checkout data structure correctness before payment processing. It formats the required metadata fields and organizes administrative information.
