我正在从数据库中获取事件列表，并尝试将类似日期与一个标题相关联。截至目前，我正在<dl> <dt> <dd>根据要求使用等。这可能会改变，但我认为这不会影响我的问题的整体影响。

基本上，我试图通过查询获取 5 个最新事件：

global $wpdb;

$sql = "SELECT e.*, c.*, ese.start_time, ese.end_time
        FROM wp_events_detail e
        JOIN wp_events_category_rel r ON r.event_id = e.id
        JOIN wp_events_category_detail c ON c.id = r.cat_id
        LEFT JOIN wp_events_start_end ese ON ese.event_id= e.id 
        WHERE e.is_active =  'Y'
        AND c.category_identifier = 'main'
        ORDER BY e.start_date ASC
        LIMIT 0, 5";
$results = $wpdb->get_results($sql);

然后我通过一个循环它们foreach()：

if(count($results) > 0) {

    echo '<div class="calendar-list">';

    foreach($results as $event) {

        $event_id = $event->id;
        $event_name = $event->event_name;
        $start_date = $event->start_date;
        $start_time = $event->start_time;

        $start_time = strtotime($start_time);
        $start_time = date('g:ia', $start_time);

        $the_time =  strtotime($start_date);

        $the_day = date('d', $the_time);
        $the_month = date('M', $the_time);

        echo '<dl class="calendar-day first-child">';
        echo '<dt>';
        echo '<p class="the-month">' . $the_month . '</p>';
        echo '<p class="the-day">' . $the_day . '</p>';
        echo '</dt>';
        echo '<dd>';
        echo '<h4><a href="' . $event_id . '">' . $event_name . '</a></h4>';
        echo '<h5><span class="time">' . $start_time . '</span></h5>';
        echo '</dd>';
        echo '</dl>';

    }

    echo '</div>';
}

我的主要问题是我需要找到一种将日期相互关联的方法。例如，6 月 27 日。如果有两个日期，我希望它看起来像：

<div class="calendar-list">
    <dl class="calendar">
        <dt>
            <p class="the-month">JUN</p>
            <p class="the-day">27</p>
        </dt>
        <dd>
            <h4><a href="#">Title</a></h4>
                        <h5><span class="time">Time</span></h5>
        </dd>
        <dd>
            <h4><a href="#">Title</a></h4>
                        <h5><span class="time">Time</span></h5>
        </dd>
    </dl>
    <dl class="calendar">
        <dt>
            <p class="the-month">JUN</p>
            <p class="the-day">28</p>
        </dt>
        <dd>
            <h4><a href="#">Title</a></h4>
                        <h5><span class="time">Time</span></h5>
        </dd>
        </dl>
</div>

我很不确定如何实现这一目标。我一直在尝试设置和取消设置一些变量，但无法达到理想的结果。

如果有人能指出我该做什么的正确方向，那将不胜感激。

谢谢！

基本上，您必须记住$the_time循环结束时的每一行，并将其与当前行进行比较，$the_time以决定是否必须回显一个新的<dt>. 然而，每一天都有自己的事实让<dl>事情变得有点复杂。这是一个丑陋的解决方案：

// Init empty previous time
$previous_time = null;
// Open first definition list
echo '<dl class="calendar-day first-child">';
foreach($results as $event) {

    $event_id = $event->id;
    $event_name = $event->event_name;
    $start_date = $event->start_date;
    $start_time = strtotime($event->start_time);
    $the_time = $start_time;
    $the_day = date('d', $start_time);
    $the_month = date('M', $start_time);
    $start_time = date('g:ia', $start_time);

    // Date changed
    if($the_time != previous_time) {
        // Unless first iteration, close previous list
        if(!empty($previous_time)) {
            echo '</dl>';
        }
        // Open new list
        echo '<dl class="calendar-day first-child">'
        // Show definition term for the group of events
        echo '<dt>';
        echo '<p class="the-month">' . $the_month . '</p>';
        echo '<p class="the-day">' . $the_day . '</p>';
        echo '</dt>';
    }

    // Display current event
    echo '<dd>';
    echo '<h4><a href="' . $event_id . '">' . $event_name . '</a></h4>';
    echo '<h5><span class="time">' . $start_time . '</span></h5>';
    echo '</dd>';

    // Remember date from previous row
    previous_time = $the_time;
}
// Close last definition list
echo '</dl>';

兄弟们，有了这段编辑过的代码，你可以按时间对任何东西进行分组
