Register Multiple Donation Fields

/**

 * If you want to add multiple new fields to your donation form,

 * you can do that in a single function.

 *

 * In the example below, we add three separate fields:

 *

 * - a text field

 * - a checkbox field

 * - a textarea field

 *

 * Note that we can use the show_before and show_after settings

 * in the donation_form array to specify where the field should appear.

 *

 * Also note that these fields will be included in the admin donation

 * form as well. Set admin_form to false if you would like to disable that.

 *
