        </div>
    <?php } ?>
</div>
</div>

我希望每个渲染出的2个项目都包含在<div class="row">中，但我无法理解。任何人都可以帮助我吗？

所以基本上这行应该包含每个循环的元素。我一直坚持这个...希望任何人都有比我更好的专业知识呵呵。

div="row"应该包裹col-sm-6和class="puff"。

Answer 1

使用正确的逻辑

    if ($i % 2 == 0) { 
        echo "</div><div class='row'>";
    }
    $i++;

首先检查其mod是否为2（在MOD之后给出0值），然后关闭div，打开新的。

现在增加反击。因为第一次，我将为0，然后你增加它，然后你使用逻辑。因此，在执行任何操作/逻辑之前，简而言之，最终只能在两端之间递增。

使用代码原样**：问题是你有i ++和你的条件在第三个，如果从未执行过。所以把它带到了All之外，就在foreach之前。

<div class="puffar">
    <?php
    //Set up the objects needed
    $my_wp_query = new WP_Query();
    $all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

    //Get children
    $children = ($post->post_parent) ? get_page_children($post->post_parent, $all_wp_pages) : get_page_children($post->ID, $all_wp_pages);

    $i = 0;
    //Build custom items
    echo "<div class='row'>";
    foreach ($children as $child) {
        ?>

        <div class="col-sm-6">
            <div class="puff">
                <div class="puff-image-holder">
                    <?php echo get_the_post_thumbnail($child->ID, 'full'); ?>
                </div>
                <fieldset class="linedHeadline hlmedium">
                    <legend><?php echo get_the_title($child->ID); ?></legend>
                </fieldset>
                <?php echo get_field("puff_introtext", $child->ID); ?>
                <?php
                $values = get_field('puff_lanktext', $child->ID);
                if (get_field("popup_eller_lank", $child->ID) == "popup") {
                    ?>
                    <fieldset class="linedHeadline hlmedium">
                        <legend><a class="linktopage open-popup"

                        </legend>
                    </fieldset>
                <?php
                } elseif (get_field("popup_eller_lank", $child->ID) == "extern") {
                ?>
                <fieldset class="linedHeadline hlmedium">
                    <legend><a class="linktopage"
                               href="<?php echo get_field("puff_lank", $child->ID); ?>"><?php echo get_field("puff_lanktext", $child->ID); ?> </a>
                    </legend>
                    <?php

                } else {
                }
                ?>
            </div>
        </div>
    <?php
        if ($i % 2 == 0) {
            echo "</div><div class='row'>";
        }

        $i++;
    } ?>
</div>
</div>

Answer 2

$i = 0;
foreach ($children as $child) {
    $i++;

    // your code goes here 
    if($i % 2 == 0) { 
        echo "</div><div class='row'>";
        // reset the counter to 0 
        $i = 0 ;
    }
}

Answer 3

首先设置$ i = 0;

if ($i % 2 == 0) { 
        echo "</div><div class='row'>";
    }
    $i++;

Php foreach循环每隔2行包裹一行
