Free add-on for the official <a href="https://woocommerce.com/products/gift-cards/" rel="nofollow ugc">WooCommerce Gift Cards</a> extension that allows you to use the default coupon form to apply and redeem gift cards.
After activating the plugin, the “Have a Gift Card?” form will be hidden, and customers will be able to apply gift card codes using the coupon input field.
Note: This plugin has been created to validate and refine a feature that may be rolled into WooCommerce Gift Cards — or dropped! — in the future.
Important: This plugin is not compatible with the Cart and Checkout Blocks.
Important: The code in this plugin is provided “as is”. Support via the WordPress.org forum is provided on a voluntary basis only. If you have an active subscription for WooCommerce Gift Cards, please be aware that WooCommerce Support may not be able to assist you with this experimental plugin.

Designed to make it easier to serve signup form on sites for LARP activities, this plugin aims to be very flexible in the way it handles input form fields.
What makes this plugin awesome is:
<ul>
<li>the ability for you to define the form you need to get the data you want.</li>
<li>the fact that it has been designed with the less is more paradigm in mind.</li>
</ul>
Thank you goes out to nkuttler of the IRC channel for his help sorting out my problems with $_POST.
