我有以下代码，我将根据中继器字段是奇数还是偶数显示不同的div 顺序，但它是不正确的，因为它重复偶数两次。有关该问题的任何帮助将不胜感激。
<!-- If Even -->
<?php if(get_field('services_repeater')): $i = 0;
while(has_sub_field('services_repeater')): $i++;
if($i % 2 == 0 ):?>
<div class="row">
<div class="span6 area-text">
<?php the_sub_field('area_text'); ?>
</div>
<div class="span6">
<!-- Carousel Open -->
<div class="slider lazy">
<?php
$variable = get_sub_field('choose_slider');
$args = array(
'post_type' => 'portfolio',
'portfolio-item' => $variable->slug
);
$the_query = new WP_Query( $args );
if($the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<div><a class="group1" href="<?php the_permalink(); ?>" title="<?php printf( the_title_attribute( 'echo=0' ) ); ?>"><div class="image">
<?php $imageID = get_field('thumbnail');
$attachment_id = get_field('thumbnail');
$size = "carousel_main_img";
$imageURL = wp_get_attachment_image_src( $attachment_id, $size ); ?>
<img data-lazy="<?php echo $imageURL[0]; ?>" />
<div class="post-content"><p class="caption"><?php printf( the_title_attribute( 'echo=0' ) ); ?></p></div>
</div></a></div>
<?php endwhile; else: ?>
<?php endif; wp_reset_postdata(); ?>
</div></div>
<!-- Carousel Closed -->
</div>
</div>
<div id="separator"></div>
<!-- End If Even -->
<?php endif; ?>
<div class="row">
<div class="span6 area-text">
<?php the_sub_field('area_text'); ?>
</div>
<div class="span6">
<!-- Carousel Open -->
<div class="slider lazy">
<?php
$variable = get_sub_field('choose_slider');
$args = array(
'post_type' => 'portfolio',
'portfolio-item' => $variable->slug
);
$the_query = new WP_Query( $args );
if($the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<div><a class="group1" href="<?php the_permalink(); ?>" title="<?php printf( the_title_attribute( 'echo=0' ) ); ?>"><div class="image">

恐怕我没有这个在线向您展示，我尝试将其简化为以下代码，但第二个仍然重复两次。
<?php if ( get_field( 'services_repeater' ) ): ?>
<?php $index = 1; ?>
<?php $totalNum = count( get_field('services_repeater') ); ?>
<?php while ( has_sub_field( 'services_repeater' ) ): ?>
<div class="col-sm-4">
<?php the_sub_field('area_text'); ?>
</div>
<? if ($index % 2 == 0) : ?>
<? if ($index < $totalNum) : ?>
Row 2<?php the_sub_field('area_text'); ?>
<? elseif ($index == $totalNum) : ?>
<? endif; ?>
<? endif; ?>
<?php $index++; ?>
<?php endwhile; ?>
<?php endif; ?>
您没有else块。您的代码简而言之如下所示：
if (($i % 2)==0) {
// do even
}
// do odd.
在偶数的情况下，偶数和做奇数将会发生。奇数部分必须进入 else 块：
if (($i % 2)==0) {
// do even
} else {
// do odd
}
代码中缺少的 else 块是以下行：
<!-- End If Even -->
<?php endif; ?>
// do odd
将其替换为
<?php else: ?>
// do odd
<?php endif ?>
while( have_rows('custom_section') ): the_row();
if( get_row_index() % 2 == 0 ){
// this is an even row
// code to display the image on the left
} else{
// this is an odd row
// code to display the image on the right
}
结束;
