Capture Resource Name (as Field Value)

<?php
/**
 * Gravity Perks // Inventory // Capture Resource Name (as Field Value)
 * https://gravitywiz.com/documentation/gravity-forms-inventory/
 *
 * If you intend to map different Resources to different fields throughout the life of your form, you may wish to capture
 * the current Resource at the time of submission and save that value to a field. This snippet can help.
 *
 * Instructions
 *
 * 1. Install the snippet.
 *    https://gravitywiz.com/documentation/how-do-i-install-a-snippet/
 *
 * 2. Enable "Allow field to be populated dynamically" option under the "Advanced" field settings for the field
 *    in which you would like to capture the Resource name.
 *
 * 3. Set the parameter name to `gpi_capture_resource_1` replacing the "1" with the GPI-enabled field ID for which
 *    you would like to capture the current resource.
