WordPress-新发布的通知数量

Question

我正在尝试在不使用任何插件的情况下发布新帖子时在前端获得一个简单的通知，此代码有效，但是如何将通知作为新帖子的计数器而不是（如果单击（在“隐藏”按钮上，我将消失。）和（隐藏）按钮像贝尔一样收集通知计数数字。

另一个问题是Cookie会在有新通知的情况下删除旧通知，因此我需要保留计数器，直到每个用户单击它为止。

hide.notification.bar.js

jQuery(document).ready(function($) {

    $("#notification_hide_button").click(function(){
        $(this).hide();
        $(".notifications_bar").hide();

        if ($.cookie( 'hide_post_cookie' ) ) { 
            $.cookie( 'hide_post_cookie', null ) 
        }
        var post_id = parseInt( cookie_Data.post_id, 10 );

        $.cookie( 'hide_post_cookie', post_id, { expires: 2, path: '/' } );

    });

});

Function.php

function enqueue_cookie_scripts() {

    wp_enqueue_script( 'jquery-cookie', get_stylesheet_directory_uri() . '/custom-js/jquery.cookie.js', array( 'jquery' ), '' , true );
    wp_register_script( 'set-cookie-option', get_stylesheet_directory_uri() . '/custom-js/hide.notification.bar.js', array( 'jquery', 'jquery-cookie'), '' , true );

    $cookie_data = array(
        'post_id' => get_option( 'new_post_notification' )->ID
    );
    wp_localize_script( 'set-cookie-option', 'cookie_Data', $cookie_data ); // this one do the magic

    wp_enqueue_script( 'set-cookie-option' );
