每 4 个帖子和 8 个帖子添加类别 -- WordPress Loop

我正在尝试构建一个内容滑块，以便每张幻灯片包含 8 张图像。为此，我需要在 WP 查询中为每 4 个帖子添加“row-fluid”类，并为每 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>';

查询打印出什么 -

php 正在将“slide”类添加到每 8 个帖子中，但第一个“slide”类未正确关闭。这听起来可能真的很令人困惑，所以如果您需要更多信息，请告诉我。

我很感激你的帮助！

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>';
