ACF Repeater Field in Flexible Content - wordpress

Question

I am trying to add a repeater field into a flexible content row but for some reason nothing is being output. I have checked the fields and they seem correct so could someone please point me out to where I am going wrong? Thanks
<?php if(get_row_layout() == "collection_title"): // layout: Collection Title ?>
<div>
<h4><?php the_sub_field("collection_title"); ?></h4>
</div>
<?php elseif(get_row_layout() == "collection_images"): // layout: Collection Images ?>
<?php if(get_field('collection_images_grid')): ?>
<?php while(has_sub_field('collection_images_grid')): ?>
<div class="collections">
<span><strong><?php the_sub_field('collection_detail'); ?></strong></span>
<a href="<?php the_sub_field('product_link'); ?>">
<img src="<?php the_sub_field('collection_image'); ?>"/>
</a>
</div>
<?php endwhile; ?>
<?php endif; ?>
<?php endif; ?>
<?php endwhile; ?>

Answer 1

your <?php if(get_field('collection_images_grid')): ?> statement should be <?php if(get_sub_field('collection_images_grid')): ?>

Answer 2

<?php
// check if the flexible content field has rows of data
if( have_rows('the_process') ){
// loop through the rows of data
while ( have_rows('the_process') ) : the_row();
if( get_row_layout() == 'content' ){
?>
<h1><?php the_sub_field('headline');?></h1>
<h2 class="tagLine paddingBottom80"><?php the_sub_field('sub_headline');?></h2>
<div class="steps clearAfter">
<?php if(get_sub_field('process_steps')): ?>
<?php
while(has_sub_field('process_steps')):
?>
<!--Step-->
<div class="processStep rel boxSizing">
<img src="images/ph.png" width="200" height="200" class="borderRadius50Perc imageBorder boxSizing" />
<div class="processBox border1 padding20 clearAfter">
<div class="third processNumber boxSizing font70 darkBlue">
<div class="border1 padding20">
<?php echo $i;?>
</div>
</div>
<div class="twothird boxSizing processContent">
<h3><?php the_sub_field('step_headline'); ?></h3>
<div class="processContentTxt grey">
<?php the_sub_field('step_content'); ?>
</div>
</div>
</div>
</div>
<!--Step-->
<?php endwhile; ?>
<?php endif; ?>
</div>
<?php
}
endwhile;
}
?>

You should change one thing in your code. Change <?php if(get_field('collection_images_grid')): ?> to <?php if(get_sub_field('collection_images_grid')): ?> and it will works! I've simulate your issue and after change to sub_field it works. Your code will be like this:
<?php if(get_row_layout() == "collection_title"): // layout: Collection Title ?>
<div>
<h4><?php the_sub_field("collection_title"); ?></h4>
</div>
<?php elseif(get_row_layout() == "collection_images"): // layout: Collection Images ?>
<?php if(get_sub_field('collection_images_grid')): ?>
<?php while(has_sub_field('collection_images_grid')): ?>
<div class="collections">
<span><strong><?php the_sub_field('collection_detail'); ?></strong></span>
<a href="<?php the_sub_field('product_link'); ?>">
<img src="<?php the_sub_field('collection_image'); ?>"/>
</a>
</div>
<?php endwhile; ?>
<?php endif; ?>
<?php endif; ?>
<?php endwhile; ?>
I had a little problems to use repeaters inside acf flexible content. So if I could say something to help in this cases is to use a variable to print the elements of repeater array, like this:
<?php if(get_row_layout() == "collection_title"): // layout: Collection Title ?>
<div>
<h4><?php the_sub_field("collection_title"); ?></h4>
</div>
<?php elseif(get_row_layout() == "collection_images"): // layout: Collection Images ?>
<?php if(get_sub_field('collection_images_grid')): ?> // considering that collections_images_grid are a repeater
<?php $collection_image = get_sub_field('collection_images_grid');?>
<?php echo $collection_image['url']; ?> <?php echo $collection_image['alt']; ?> //Or something that you would like to use [... and than the rest of code]

Assuming your repeater field is collection_images_grid, you should loop through the items with have_rows(), like this:
<?php if(get_row_layout() == "collection_title"): // layout: Collection Title ?>
<div>
<h4><?php the_sub_field("collection_title"); ?></h4>
</div>
<?php elseif(get_row_layout() == "collection_images"): // layout: Collection Images ?>
<?php if(have_rows('collection_images_grid')): ?>
<?php while(have_rows('collection_images_grid')): the_row(); ?>
<div class="collections">
<span><strong><?php the_sub_field('collection_detail'); ?></strong></span>
<a href="<?php the_sub_field('product_link'); ?>">
<img src="<?php the_sub_field('collection_image'); ?>"/>
</a>
</div>
<?php endwhile; ?>
<?php endif; ?>
<?php endif; ?>
This essentially checks if the flexible content field has rows of data (<?php if(have_rows('collection_images_grid')): ?>), and then loops through / displays them (<?php while(have_rows('collection_images_grid')): the_row(); ?>).

Answer 5

To debug all the Advanced Custom Fields on a page and get a better understanding of the structure, I often use the following PHP snippet:
echo '<pre>';
var_dump(get_fields());
echo '</pre>';
This helps to make sure the data is available, and figure out how to reach it in the nested structure.
