分页有效，但不太正确.在第二页上重复第一篇文章

Question

我的分页不太有效。只有 4 个事件，分页设置为每页 3 个。当我加载第二页时，它会自行再次加载第一个事件，而不是最后一个帖子。

我的代码如下。我正在使用 kirby 内容管理器，但我认为这些东西在各个网站上非常统一。我很确定它不起作用，因为我的事件循环内部的循环，但我不知道如何纠正它。

<div id="main-container">
  <div class="content">

              $i++; ?>
              <li class="event-list-item">
                <?php $calendar = page('events')->children()->nth($i)->calendar()->yaml();
                  foreach($calendar as $calendarEntry) { ?>

Wall，我很乐意在这里提供帮助，但需要更多上下文进入您的代码。你的循环中似乎有一些重复。不奇怪为什么你在循环中使用$i变量。从外观上看，您可以摆脱更简单的事情：

<div id="main-container">
<div class="content">
    <div class="container">
      <div class="row">
        <div class="col-md-12 content-block">
          <ul class="events-list">
          <?php $events = $page->children()->paginate(3);
            foreach($events as $event): ?>
              <li class="event-list-item">
                <?php $calendar = $event->calendar()->yaml();
                  foreach($calendar as $calendarEntry) { ?>
                      <span class="event-date">
                        <span class="date">
                          <?php

                            echo date('j',$eventday);
