<?php
/**
 * This recipe replaces the function for the shortcode [pmpro_member_profile]
 * with a custom shortcode function that applies wpautop to the user bio,
 * which creates paragraphs from double line breaks, and nl2br to other fields,
 * which converts line breaks to html line break <br />.
 *
 * @link https://developer.wordpress.org/reference/functions/wpautop/
 * @link https://www.php.net/manual/en/function.nl2br
 *
 * This recipe is compatible with PMPro Member Directory
 * @version 1.1
 * @link https://www.paidmembershipspro.com/add-ons/member-directory/
 *
 * It is important to regularly check for any changes to the profile shortcode
 * that this recipe is derived from and apply any updates to this recipe where necessary.

 * 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.
