我正在为一位客户开发一个自定义模板，该客户希望在其网站中能够按月筛选帖子。创建存档后。php页面，并将小部件“归档”放在我的侧边栏中，我能够循环并过滤他想要发布的所有帖子，但实际上每个月的最后一篇帖子都没有加载。基本上每个帖子都会每月过滤一次，但不是最后一篇。这是我的存档页面，其中包含存档简单循环：

<?php get_header(); /** Template Name: Archivio */ ?>

<?php if ( have_posts() ) : the_post(); ?>


<section id="news-eventi">
    <div class="container">
        <div class="breadcrumb-site">
            <div class="breadcrumbs" typeof="BreadcrumbList" vocab="http://schema.org/">

                <h5 class="text-uppercase font-weight-light"><?php
    if(function_exists(\'bcn_display\')) {
        bcn_display();
    }
?></h5>
            </div>
        </div>
        <div class="row border-left">
            <div class="col-lg-9">
                <div class="page-title">
                    <h1 class="text-uppercase"><?php if ( is_month() ) { echo \'ARCHIVIO NEWS: \' . get_the_date(\'F Y\'); } ?></h1>
                </div>



    <!-- Start the Loop. -->
