/**
 * Allow users to add an avatar at checkout for the Basic User Avatars plugin.
 *
 * This recipe assumes that you have the Basic User Avatar plugin installed and activated.
 * @link https://wordpress.org/plugins/basic-user-avatars/
 *
 * This recipe requires a custom user field created with the name basic_user_avatar.
 * The field should be set to "No" for the display on the profile option for either
 * the group (Show fields on user profile?) or the field (Show field on user profile?).
 *
 * You can add this recipe to your site by creating a custom plugin
 * or using the Code Snippets plugin available for free in the WordPress repository.
 * Read this companion article for step-by-step directions on either method.
