如何在我的代码中的第3列之后创建新行

我正在自定义主题, 其中可以选择仅添加三个服务部分。我添加了更多的三个部分, 并且在我的HTML中得到了体现。 defacult正在创造这样的东西：

行> col1> col1> col1> col1> col1> col1

我想创建像这样：

行> col1> col1> col1行> col1> col1> col1

请帮助我

你可以使用类似以下的逻辑：

<?php 

                            $col_count = 1;
                            while( $lesson_qry->have_posts() ){ $lesson_qry->the_post(); ?>


                                  <?php if($col_count==1){ ?>
                                    <div class="row"> 
                                  <?php } ?>                                

                                        <div class="col">

                                            <?php 
                                                if( has_post_thumbnail() ){ ?>
                                                    <div class="img-holder">

                                                    </div>
                                            <?php } ?>

                               } ?>

一个非常简单的解决方案是包括一个计数器, 并使用一个模运算符关闭并重新打开行div, 如下所述：

if( $lesson_qry->have_posts() ){ 
  $counter = 0;
   ?>
                <div class="row">

                   <?php 
                    while( $lesson_qry->have_posts() ){ $lesson_qry->the_post();
                      if ($counter%3 == 0) {
                       ?>
                       </div>
                       <div class="row">
                      <?php }?>
                        <div class="col">

                            <?php 
                                if( has_post_thumbnail() ){ ?>
                                    <div class="img-holder">
                                        <?php the_post_thumbnail( 'preschool-and-kindergarten-lesson-thumb', array( 'itemprop' => 'image' ) ); ?>
                                    </div>
                            <?php } ?>

                            <div class="text-holder">
                                <h3 class="title"><?php the_title(); ?></h3>
                                <?php the_content(); ?>
                            </div>

                        </div>      

                    <?php 
                     $counter++;
                     } ?>

                </div>
            <?php }

更改

可能你需要这样的东西

if( $lesson_qry->have_posts() ){ ?>
       <?php 
        $i = 0;
        while( $lesson_qry->have_posts() ){ $lesson_qry->the_post(); ?>

            <?php if( ($i % 3) == 0) {?>
                <div class="row">
            <?php } ?>
            <div class="col">
                <?php 
                    if( has_post_thumbnail() ){ ?>
                        <div class="img-holder">
                            <?php the_post_thumbnail( 'preschool-and-kindergarten-lesson-thumb', array( 'itemprop' => 'image' ) ); ?>
                        </div>
                <?php } ?>

                <div class="text-holder">
                    <h3 class="title"><?php the_title(); ?></h3>
                    <?php the_content(); ?>
                </div>

            </div>      
            <?php if( ($i % 3) == 0) { ?>
                </div>
            <?php
                }
           $i++;
        } ?>

    </div>
<?php } ?>
