我知道这不是正确的方法，您应该始终编辑模板，但我只是编辑了核心好友按导航功能。你会看到下面我添加的谷歌链接。

 function bp_get_displayed_user_nav() {
global $bp;

foreach ( (array) $bp->bp_nav as $user_nav_item ) {
    if ( empty( $user_nav_item[\'show_for_displayed_user\'] ) && !bp_is_my_profile() )
        continue;

    $selected = \'\';
    if ( bp_is_current_component( $user_nav_item[\'slug\'] ) ) {
        $selected = \' class="current selected"\';
    }

    if ( bp_loggedin_user_domain() ) {
        $link = str_replace( bp_loggedin_user_domain(), bp_displayed_user_domain(), $user_nav_item[\'link\'] );
    } else {
        $link = trailingslashit( bp_displayed_user_domain() . $user_nav_item[\'link\'] );
    }

    echo apply_filters_ref_array( \'bp_get_displayed_user_nav_\' . $user_nav_item[\'css_id\'], array( \'<li id="\' . $user_nav_item[\'css_id\'] . \'-personal-li" \' . $selected . \'><a id="user-\' . $user_nav_item[\'css_id\'] . \'" href="\' . $link . \'">\' . $user_nav_item[\'name\'] . \'</a></li>\', &$user_nav_item ) );
}

echo "<li id=\\"css-personal-li\\"><a href=\'http://www.google.com\'>Google</a></li>";
