Php foreach 循环包装每 2 个项目

Question

<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 );

        $i = 0;
        //Build custom items 
        foreach($children as $child){ 
        $i++;

        /*
        if (i % 2 == 0) { ?>

        <?php
        } */
        ?>

<div class="col-sm-6">
    <div class="puff">
        <div class="puff-image-holder">
            <?php echo get_the_post_thumbnail( $child->ID, 'full' ); ?>

嗨堆垛机!

我需要一些关于如何包装循环元素的 php 帮助。我想将 2 个元素包装在 <div class="row">. 中所以基本上 <row> <item> <item> </row>

如您所见，我尝试了一些模数，一些 if 语句仍然存在。我将 i 设置为 0，并试图将 <div class="row">当 1 % 2 = 0 但没有找到关于如何正确关闭标签的解决方案(应该在第二项之后关闭)你有没有机会帮助我这个新手 php 黑客？

编辑:

    <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", $child->ID ) == "popup") {
        ?>
        <fieldset class="linedHeadline hlmedium">
            <legend><a class ="linktopage open-popup" href="<?php echo get_page_link($child->ID); ?>"><?php echo get_field( "puff_lanktext", $child->ID ); ?> </a></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
        $i++;  
        if ($i % 2 == 0) { 
            echo "</div><div class='row'>";
        }
        } else { }
        ?>
    </div>
</div>

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

这只包装了我所有的循环项目，我希望 div class=row 只包装每 2 个项目

你快到了:

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

        echo "item "; 

        $i++;  
        if ($i % 2 == 0 && $i != count($children)) { 
            echo "</row><row>";
        }

    }
    echo "</row>"
