Bypass New User Approve if certain Membership(s) is purchased in MemberPress

nua-bypass-by-membership.php

<?php
function nua_allow_user_if_membership($errors) {
  $allowed_memberships = array(123,321,789,987); // CHANGE THIS

  if(!is_user_logged_in()) {
    if(in_array((int)$_POST['mepr_product_id'], $allowed_memberships)) {
      $_REQUEST['action'] = 'createuser'; //Set this so "New User Approve" plugin will not limit the subscriber
    }
  }

  return $errors;
}
add_filter('mepr-validate-signup', 'nua_allow_user_if_membership');

This can be pasted into a plugin like Code Snippets (run everywhere type snippet).

Edit line #2 and change the comma-separated list of ID's to the Membership ID's from MemberPress that you wish to allow new users to bypass approval on.

You can get a MemberPress membership ID by visiting the MemberPress > Memberships page in your wordpress dashboard and the ID's should be listed in the far-left column.
