Reply To: custom fields?

Where would I put:

   add_shortcode( 'connections_edit_link', 'cn_edit_my_entry_shortcode' );

function cn_edit_my_entry_shortcode() {

    // Grab an instance of the Connections object.
    $instance = Connections_Directory();

    // Get the current user ID.
    $userID  = get_current_user_id();

    // Check to see if the entry has been linked to a user ID.
    $entryID = get_user_meta( $userID, 'connections_entry_id', TRUE );

    $results = $instance->retrieve->entries( array( 'id' => $entryID ) );

    if ( is_user_logged_in() &&
        ( $userID == $results[0]->user && $entryID == $results[0]->id ) &&
        ( current_user_can( 'connections_edit_entry' ) || current_user_can( 'connections_edit_entry_moderated' ) )
       ) {

        return cnURL::permalink( array( 'type' => 'edit', 'slug' => $results[0]->slug, 'text' => 'Edit My Entry', 'return' => TRUE ) );
    }
}

Thanks!
