中继器高级自定义字段中的随机中继器

Question

我正在使用高级自定义字段并且在转发器中有一个转发器。我需要嵌套的中继器随机拉一排。这是我没有用的东西：

<?php $i = 0; while(the_repeater_field('squares')): ++$i;
        $repeater = get_sub_field( 'images' );
        $rand = rand(0, (count($repeater) - 1));?>
        <a href="<?php the_sub_field('link'); ?>" class="fs-square" style="background-image:url('<?php echo $rand['four-square']; ?>')">    
            <div class="main-text"><?php the_sub_field('main_text'); ?></div>
            <div class="icon-section">
                <div class="icon"><?php the_sub_field('icon'); ?></div>
                <div class="icon-text"><?php the_sub_field('icon_text'); ?></div>
            </div>
        </a>
    <?php endwhile; ?>

基本上，我有一个正方形中继器，然后我有一个图像中继器。我需要图像中继器是随机的。

Answer 1

你可能想试试

<?php echo $repeater[$rand]['four-square']; ?>

而不是

<?php echo $rand['four-square']; ?>

HTH！

Answer 2

这是为我修复的。

<?php 
    $i = 0; 
    while(have_rows('squares')): 
    the_row();
        $i++;
        $repeater = get_sub_field( 'images' );
        $rand = rand(0, (count($repeater) - 1)); //does not select a specific row but rather just a number
        ?>
        <a href="<?php the_sub_field('link'); ?>" class="fs-square" style="background-image:url('<?php echo $repeater[$rand]['image']['sizes']['four-square']; ?>')">   
            <div class="main-text"><?php the_sub_field('main_text'); ?></div>
            <div class="icon-section">
                <div class="icon"><?php the_sub_field('icon'); ?></div>
                <div class="icon-text"><?php the_sub_field('icon_text'); ?></div>
            </div>
        </a>
    <?php endwhile; ?>
