BuddyPress.org

I’m using WPMUDEV’s Membership 2 Pro plugin. I’d like to add XProfile fields to the registration form. Here’s my attempt:

<?php

add_action('signup_extra_fields', 'igi_change_reg_fields');

function igi_change_reg_fields() {
  if ( bp_is_active( 'xprofile' ) ) : if ( bp_has_profile() ) : while ( bp_profile_groups() ) : bp_the_profile_group();
  echo '<input type="hidden" name="'.bp_the_profile_field_input_name().'" id="'. bp_the_profile_field_input_name().'" value="'. bp_the_profile_field_edit_value().'"';

   endwhile; endif; endif;

}

This produces:

field_field_
Warning: Creating default object from empty value in /home/bennyp5/public_html/israelguides.info/wp-content/plugins/buddypress/bp-xprofile/bp-xprofile-template.php on line 520

Please help me to understand where I’m going wrong.

Best,
