Repeater inside Group ACF Wordpress

Question

I'm using Advanced Custom Fields for Wordpress and trying to loop a repeater inside a group. All I get is "Notice: Array to string conversion in..."

What's wrong & how do I fix it?

<?php if( have_rows('start_horlurar') ): while ( have_rows('start_horlurar') ) : the_row();  ?>

<?php $horlur = get_sub_field('horlur'); ?>

<?php if( have_rows( $horlur['arsmodeller_lankar']) ): while ( have_rows($horlur['arsmodeller_lankar']) ) : the_row();  ?>

<?php echo get_sub_field('lank'); ?>

<?php endwhile; endif; ?>

<?php endwhile; endif; ?>

Aberration

please post minimal code – Lowbred

I did, but it disappeared. – Aberration

what is this field "lank" text or image or someother – Lowbred

It's the sub field in the repeater "arsmodeller_lankar" – Aberration

try this, the_field('lank'); – Lowbred

doesn't make a difference. – Aberration

It doesn't seem to loop the repeater at all – Aberration

Here's a plain and simple guide to repeaters inside groups (wpza.net/use-a-repeater-inside-a-group) if it helps anyone. – Diversify

Answer 1

In nested ACF Repeaters, you need not to add the reference of parent repeater - just add the repeater name alone. Try like this.

<?php
if( have_rows('start_horlurar') ): while ( have_rows('start_horlurar') ) : the_row(); 
    echo get_sub_field('horlur');
    if( have_rows('arsmodeller_lankar') ): while ( have_rows('arsmodeller_lankar') ) : the_row(); 
        echo get_sub_field('lank');
    endwhile; endif;
endwhile; endif;
?>

UPDATED CODE: You need to loop the ACF Group field too like ACF Repeater. Try like this.

<?php
if( have_rows('start_horlurar') ): while ( have_rows('start_horlurar') ) : the_row(); 
    if( have_rows('horlur') ): while ( have_rows('horlur') ) : the_row();       
        if( have_rows('arsmodeller_lankar') ): while ( have_rows('arsmodeller_lankar') ) : the_row(); 
            echo get_sub_field('lank');
        endwhile; endif;
    endwhile; endif;
endwhile; endif;
?>

It dosen't output anything. Not even echo "hello world"; – Aberration

Can you confirm that start_horlurar is parent repeater name & arsmodeller_lankar is the child repeater under that? – Starstarboard

But the lank field seems to be under start_horlurar and not arsmodeller_lankar? – Starstarboard

Seems horlur a group field between those, can you just confirm the hierarchy - start_horlurar (repeater) > horlur (group) > arsmodeller_lankar (repeater)? – Starstarboard

Yes! :) Therefore the title of the question – Aberration

No problem! :) It Worked, you're a genius! – Aberration

The updated code it was worked for me (i.e. the group needed to be looped as well). Thanks! – Departed

Answer 2

I believe this was answered correctly, but it did not seem clear enough for those looking for a generic implementation.

<?php

if( have_rows('your_group') ): while ( have_rows('your_group') ) : the_row(); 

    if( have_rows('your_repeater') ): while ( have_rows('your_repeater') ) : the_row();       

        echo get_sub_field('repeater_sub_field');

    endwhile; endif;

endwhile; endif;

?>

Normally with groups you can reach specific subfields by using:

<?php 

$group_var = get_field['your_group']; 

$group_sub_field_var = $group_var['group_sub_field']

?>

However, it seems with repeaters nested inside of groups you cannot use this strategy and are forced to loop through a group first using have_rows() to even reach the repeater.

If you look at the group documentation on ACF it mentions how looping through a group is done like a repeater. Also the have_rows() documentation has more detail about nested loops using have_rows().

Answer 3

I find the double loop messy and not needed. I realize this is old, but I just had this issue and didn't want to have two loops.

For my group ('group') and my repeater ('repeater'), with a subfield of ('subfield') this is what I did.

     $group = get_field('group');
     $repeaters = $group['repeaters'];
     foreach($repeaters as $repeater) {
         echo $repeater["subfield"];
       }

Super easy, and it's much more clean. You can add your 'if' statements if needed and not controlled my mandatory fields.

I find this method important for quick and dirty. I use groups for almost everything to be able to create a better user experience for the custom fields in the back end. Most of my custom fields are in groups and grabbing the args, I want it to be as little code and as clean as possible.

Let me know if you guys find any issues with this method, especially in regards to performance.

This worked for me, and is neater than the double loop – Calysta

...but you're loosing the benefit of checking if group, or repeater, or sub field exists. – Toolis

Answer 4

I format it like this, I think it's much cleaner:

<?php if(have_rows('features_repeater')): while(have_rows('features_repeater')): the_row(); if(have_rows('features_group')): while(have_rows('features_group')): the_row(); ?>
    
    <h1><?php echo get_sub_field('title'); ?></h1>

<?php endwhile; endif; endwhile; endif; ?>

Answer 5

This code can works with one or two repeater in one Group

<?php if (have_rows('your_group_name')): ?>
    <?php while (have_rows('your_group_name')): the_row();
        if (have_rows('your_repeater_name')): ?>
            <ul>
            <?php while (have_rows('your_repeater_name')): the_row();
                $your_repeater_item = get_sub_field('your_repeater_item');
            ?>
                <li><?php echo $your_repeater_item; ?></li>
            <?php endwhile; ?>
            </ul>
        <?php endif; ?>
    <?php endwhile; ?>
<?php endif; ?>

If you use two repeaters in Group field, just copy this code twice and replace variables names. I hope this code helps somebody.
