ACF奇/偶中继器

Question

I'm trying to create a two column element using ACF repeater fields. The only thing is I'm trying to alternate this so that the content in the two columns switches left/right depending on the row being even or odd.

The output will look something like:

Row 1: Image (left column), Description (right column)

Row 2: Description (left column), Image (right column)

Row 3: Image (left column), Description (right column)

Row 4: Description (left column), Image (right column)

.

.

.

This is how I looped it:

<section id="projects" class="container specific-margin-1">
        <div class="row specific-padding-4">
            <div class="container col-lg-12">
                <center><h2>FEATURED PROJECTS</h2></center>
            </div><!-- col-lg-12  --> 
        </div><!-- row  -->

            <!-- Repeater --> 
            <div class="row">
            <?php $row = 0; //<-- set your counter to 0
                        if(get_field('featured_projects')): ?>
            <?php while(has_sub_field('featured_projects')): ?>

                <?php if ($counter % 2 === 0) :?>
                <div class="row">
                    <!-- right column -->
                    <div class="col-lg-9 col-md-8 col-sm-6">
                        <img src="<?php the_sub_field('project_image'); ?>" />
                    </div>

                    <div class="col-lg-3 col-md-4 col-sm-6">
                            <?php the_sub_field('project_details'); ?>
                    </div><!-- right column -->
                </div>

                <?php else: ?>

                <div class="row">
                    <!-- left column -->
                    <div class="col-lg-3 col-md-4 col-sm-6">
                        <?php the_sub_field('project_details'); ?>
                    </div>

                    <div class="col-lg-9 col-md-8 col-sm-6">
                        <img src="<?php the_sub_field('project_image'); ?>" />
                    </div><!-- left column -->
            </div>
            <?php endif; ?>

            <?php $row++; endwhile; ?>

            <?php endif; ?>
        </div><!-- Repeater -->
    </section>

Make sure to change your ACF Image field to 'Image Array':

ACF Image Field

<!-- Repeater -->
<div class="row">
  <?php $i=0 ; if(get_field( 'featured_projects')): ?>
  <?php while(has_sub_field( 'featured_projects')): $i++; ?>
  <?php $image=get_sub_field( 'project_image'); ?>
  <div class="row">
    <!-- right column -->
    <div class="col-lg-9 col-md-8 col-sm-6">
      <?php if (($i % 2)==0 ): ?>
      <?php the_sub_field( 'project_details'); ?>
      <?php else: ?>
      <img src="<?php echo $image['url']; ?>" />
      <?php endif; ?>
    </div>

    <div class="col-lg-3 col-md-4 col-sm-6">
      <?php if (($i % 2)==0 ): ?>
      <img src="<?php echo $image['url']; ?>" />
      <?php else: ?>
      <?php the_sub_field( 'project_details'); ?>
      <?php endif; ?>
    </div>
    <!-- right column -->
  </div>

  <?php endwhile; ?>

  <?php endif; ?>
</div>
<!-- Repeater -->

</div>
