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?

Hi @forbiddenchunk

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 🙂
