Home › Forums › Front-end Issues › Select fields in repeater, in repeater…
I am pushing myself a little here and need some help please;
I am trying to have a multiple select area in a repeater, in a repeater…
This is code I have so far;
<?php while ( have_posts() ) : the_post(); ?>
<?php
// check for rows (parent repeater)
if( have_rows('certificate_area') ): ?>
<div id="certificate_area">
<div class="flex-wrapper">
<?php
// loop through rows (parent repeater)
while( have_rows('certificate_area') ): the_row(); ?>
<?php
// check for rows (sub repeater)
if( have_rows('item') ): ?>
<?php
// loop through rows (sub repeater)
while( have_rows('item') ): the_row();
// display each item as a list - with a class of completed ( if completed )
?>
<div class="flex-shell <?php the_field('class'); ?>">
<div class="flex-item">
<div class="image">
<a href="<?php the_sub_field('image'); ?>" class="fancybox">
<img src="<?php the_sub_field('image'); ?>" alt="">
</a>
</div>
<div class="copy">
<h2><?php the_sub_field('title'); ?></h2>
<p><?php the_sub_field('overview'); ?></p>
<div class="icon">
<?php
$images = array(
'Electrical' => get_template_directory_uri(). '/dist/images/elec-icon.png',
'Lighting' => get_template_directory_uri(). '/dist/images/lights-icon.png',
);
$values = get_field('area');
foreach ($values as $value) {
?>
<img src="<?php echo $images[$value] ?>" alt="">
<?php
}
var_dump( $images );
?>
</div>
</div>
</div>
</div>
<?php endwhile; ?>
<?php endif; //if( get_sub_field('items') ): ?>
<?php endwhile; // while( has_sub_field('to-do_lists') ): ?>
</div>
</div>
<?php endif; // if( get_field('to-do_lists') ): ?>
<?php endwhile; // end of the loop. ?>
As in the select section (near the bottom) I am getting the following error;
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\napit-desktop-website-wp\wp-content\themes\napit-desktop-website\templates\template-certificates.php on line 63
I have turned on debug and it added;
array(2) { [“Electrical”]=> string(107) “//localhost:3000/desktop-website-wp/wp-content/themes/desktop-website/dist/images/elec-icon.png” [“Lighting”]=> string(109) “//localhost:3000/desktop-website-wp/wp-content/themes/desktop-website/dist/images/lights-icon.png” }
Can anyone help please?
I believe it has something to do with this code:
$values = get_field('area');
If the “area” field is located in a repeater, you should get the value like this:
$values = get_sub_field('area');
If that doesn’t help, could you please share the JSON export file of your field group so I can test it out on my installation?
Thanks 🙂
Hi @acf-support
That worked, thanks! Can’t believe I didn’t realise it needed to be a sub field
Thanks 🙂
