BuddyPress.org

I’m trying to make registering on the site require a passphrase to complete the registration (a form of spam filtering / needing to be human).

when I go through the steps, to register, the field is there, and if entered correctly, it works, but if it’s blank, or just wrong, it just kicks me to a white screen error with:

“There has been a critical error on this website.

It would seem something is wrong with the error handling in my function. help?

function bp_add_passphrase_field() {
?>
  <div class="register-section" id="profile-details-section">
    <div class="editfield">
      <label for="passphrase"><?php _e( 'What sport do the Steelers play?', 'buddypress' ); ?> <?php _e( '(required)', 'buddypress' ); ?></label>
      <input type="password" name="passphrase" id="passphrase" value="" />
    </div>
  </div>
<?php
}
add_action( 'bp_before_registration_submit_buttons', 'bp_add_passphrase_field' );

// Validate the custom passphrase field on form submission
function bp_validate_passphrase_field( $result ) {
  // Set the desired passphrase
  $correct_passphrase = 'football';

  if ( $_POST['passphrase'] != $correct_passphrase ) {
    $result['errors']->add( 'passphrase_error', __( 'The passphrase you entered is incorrect.', 'buddypress' ) );
  }
  return $result;
}
add_filter( 'bp_signup_validate', 'bp_validate_passphrase_field' );
?>
