php - 为每 4 个帖子和 8 个帖子添加课程——WordPress Loop

Question

我正在尝试构建一个内容滑块，以便每张幻灯片包含 8 个图像。为此，我需要在我的 WP 查询中每 4 个帖子添加“row-fluid”类，每 8 个帖子添加“slide”类。

我试图实现的 HTML -

<div class="coda-slider"  id="slider-id">

  <div class="slide">

    <div class="row-fluid">
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
    </div><!-- /row-fluid -->

    <div class="row-fluid">
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
    </div><!-- /row-fluid -->

  </div><!-- /slide -->

  <div class="slide">

    <div class="row-fluid">
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
    </div><!-- /row-fluid -->

    <div class="row-fluid">
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
      <div class="span3">
        <img src="...">
      </div>
    </div><!-- /row-fluid -->

  </div><!-- /slide -->

</div><!-- /coda-slider -->

我的查询无法正常工作 -

<?php

$args = array( 'post_type' => 'video', 'posts_per_page' => 10,);

$the_query = new WP_Query( $args );

echo '<section id="our-clients">';

echo '<div class="coda-slider"  id="slider-id">';   

$i = 1;

echo '<div class="slide">';

echo '<div class="row-fluid">';

if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post();

echo '<div class="span3">';

the_post_thumbnail();

echo '</div>';

     if($i % 8 == 0) {echo '</div><div class="slide">';}

     elseif($i % 4 == 0) {echo '</div><div class="row-fluid">';}

$i++; endwhile; endif;

echo '</div>'; //row-fluid

echo '</div>'; //slide

echo '</div>'; //coda-slider

echo '</section>';

查询打印的内容 -

php 为每 8 个帖子添加一个“幻灯片”类，但第一个“幻灯片”类没有正确关闭。这可能听起来很令人困惑，所以如果您需要更多信息，请告诉我。

感谢您的帮助！

尝试这个 ;）

<?php

$args = array( 'post_type' => 'video', 'posts_per_page' => 10,);

$the_query = new WP_Query( $args );

echo '<section id="our-clients">';

echo '<div class="coda-slider"  id="slider-id">';   

for($i=1; $the_query->have_posts(); $i++)
{
    $the_query->the_post();

    $prePost='';
    $postPost='';

    if($i==1)
    {
        $prePost='<div class="slide"><div class="row-fluid">';
    }
    if($i==4)
    {
        $prePost='</div><div class="row-fluid">';
    }

    if($i==8)
    {
        $postPost='</div></div>';
        $i=0;
    }

    echo $prePost, '<div class="span3">';
    the_post_thumbnail();
    echo '</div>', $postPost;
}


echo '</div>'; //coda-slider

echo '</section>';

您可以尝试使用get_posts和array_chunck

$args = array( 'post_type' => 'video', 'posts_per_page' => 10,);
$posts = get_posts($args);
$postGroups = array_chunk($posts, 8);

foreach($postGroups as $group) :
    echo "<div class='slide'>";
        $slides = array_chunk($group, 4);
        foreach($slides as $fluides) :
            echo "<div class='row-fluide'>";
                foreach($fluides as $video) : setup_postdata($video)
                    <div class="span3">
                       // ...
                    </div>
                endforeach;
            echo "</div>";
        endforeach;
    echo "</div>";
endforeach;
