Getting Select Field Values From Post Object Inside Repeater

Hello,

So I know my title is confusing. So I will explain what is going on.

I have a CPT called downloads, which has a ACF Select Field for the type of download. I only have one other ACF type for the this CTP, which is a URL field type.

Then I have a page called “downloads” using an ACF Repeater, and the only sub-field being a Post Object, that allows you to select which Downloads you want to display.

To help understand my code, here are my field names and what type they are:

Downloads CPT:

button_url – URL Field
download_type – Select Field

Downloads Page Template (not used as an archive or single template for individual downloads CPT’s, but a page where I can specify which downloads I want to provide):

featured_downloads – Repeater
download – Post Object (sub field of featured_downloads)

Here is my code:

<?php

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

		$download_object = get_sub_field('download');

		if( $download_object ) :
			$post = $download_object;
			setup_postdata( $post );

			$type = get_field_object( 'download_type' );
			$value = $type['value'];
			$label = $type['choices'][ $value ];
			$url = get_field( 'button_url' );
	?>      	

	<div class="featured-download row">
		<div class="medium-5 columns text-center">
		<?php the_post_thumbnail( 'full' ); ?>
		</div>
		<div class="medium-7 columns">
			<div class="download-type"><?php echo $label; ?></div>
			<h3><?php the_title(); ?></h3>
			<a href="<?php echo $url; ?>" class="button">Download Now</a>
		</div>
	</div>
<?php wp_reset_postdata(); endif; endwhile; endif; ?>

I’m able to display exactly what I need except the $label variable that stores the label for the select value. I get this error message:

Warning: Illegal offset type in …(the path to the file the above code is on) on line 12.

Line 12 in my code is the setting of the $label variable.

Any help would be greatly appreciated

Hi @kiwicreative

Could you please share the JSON export file of your field group so I can test it out on my installation?

Thanks 🙂

Hi @kiwicreative

Thanks for sharing the JSON file.

I’ve just checked it and found out that the Return Format of the download_type field is set to “Both (Array)”. In this case, you don’t need to use the get_field_object() function anymore. You should be able to do it like this:

$type = get_field( 'download_type' );
$value = $type['value'];
$label = $type['label'];

I hope this helps 🙂
