Question

这里我有一个foreach循环，可以查看客户端可查看的日期日历。在第一个循环中，我将$ i作为变量等于0.然后我给出规则，声明如果$ i等于0或者可以被3整除，则回显div类组。但是，如果循环在$ i等于1时退出，或者可以被2整除以关闭类组并继续向下移动html。出于某种原因，当我有一个或两个条目时，该组未正确关闭，并且内部捕获了以下div。请你看看这段代码，看看我搞砸了......

    <div class = "calender_dates">
<div class = 'calender_select'>
    <div class = 'dates past active'></div>
    <div class = "dates future"></div>

    <?php $i=0 ?>
@foreach($past as $event)
<?php if($i==0 OR is_int($i/3)){
        if($i==0){
            echo '<div class="group_loop_first">';
        } else{
            echo '<div class="group_loop">';
        }

              } ?>

Answer 1

您遇到了问题，因为您过早地增加了计数器。下面的代码会被清理一下，但基本的想法是，在您检查是否需要结束div标签之前，不应该增加计数器。

<div class="past_events grid-calender">
    <?php $i = 0; ?>
    @foreach($past as $event)
        @if ($i == 0)
    <div class="group_loop_first">
        @elseif ($i % 3 === 0)
    <div class="group_loop">
        @endif
        <div class = "p_date grid-date">
            <!-- rest of html -->
        </div>

        @if ($i % 3 === 0)
    </div>
        @endif
        <?php $i++; ?>
    @endforeach
</div>

<div class="future_events grid-calender">
    <?php $i = 0; ?>
    @foreach($future as $event)
        @if ($i % 3 === 0)
    <div class="group_loop">
        @endif
        <div class = "p_date grid-date">
            <!-- rest of html -->
        </div>
        @if ($i % 3 === 0)
    </div>
        @endif
        <?php $i++; ?>
    @endforeach
</div>
