wordpress页面中仅限Facebook的登录按钮

我需要在页面中插入一个仅限Facebook的登录按钮，不使用其中一个功能重定向（登录后的用户保持在同一页面上），如果可能的话创建一个短代码 . 这些功能来自网站上的活动插件 . 该插件管理所有wordpress登录，但我需要在一个页面上只登录Facebook .

add_action('userpro_inside_form_submit','userpro_social_connect');

function userpro_social_connect($array){

    global $userpro;



    // only in login/register

    if ($array['template'] == 'login' || $array['template'] == 'register' ) {



        echo '<div class="userpro-social-connect">';



        if (userpro_get_option('facebook_app_id') != '' && userpro_get_option('facebook_connect') == 1) {

            ?>



            <div id="fb-root" class="userpro-column"></div>

            <script>

            window.fbAsyncInit = function() {



                FB.init({

                    appId      : "<?php echo userpro_get_option('facebook_app_id'); ?>", // Set YOUR APP ID

                    status     : true, // check login status

                    cookie     : true, // enable cookies to allow the server to access the session

                    xfbml      : true  // parse XFBML

                });



                FB.Event.subscribe('auth.authResponseChange', function(response)

                {

                if (response.status === 'connected')

                {



                //SUCCESS



                }   

                else if (response.status === 'not_authorized')

                {



                //FAILED



                } else
