How to display exactly?

WordPress has messed up the usage area where the code is but let paste it over here.

<?php
	//Get the images ids from the post_metadata
	$images = acf_photo_gallery('gallery_images', $post->ID);
	//Check if return array has anything in it
	if( count($images) ):
		//Cool, we got some data so now let's loop over it
		foreach($images as $image):
			$title = $image['title']; //The title
			$caption= $image['caption']; //The caption
			$full_image_url= $image['full_image_url']; //Full size image url
			$full_image_url = acf_photo_gallery_resize_image($full_image_url, 262, 160); //Resized size to 262px width by 160px height image url
			$thumbnail_image_url= $image['thumbnail_image_url']; //Get the thumbnail size image url 150px by 150px
			$url= $image['url']; //Goto any link when clicked
			$target= $image['target']; //Open normal or new tab
			$alt = get_field('photo_gallery_alt', $id); //Get the alt which is a extra field (See below how to add extra fields)
			$class = get_field('photo_gallery_class', $id); //Get the class which is a extra field (See below how to add extra fields)
?>
<div class="col-xs-6 col-md-3">
	<div class="thumbnail">
		<?php if( !empty($url) ){ ?><a href="<?php echo $url; ?>" <?php echo ($target == 'true' )? 'target="_blank"': ''; ?>><?php } ?>
			<img src="<?php echo $full_image_url; ?>" alt="<?php echo $title; ?>" title="<?php echo $title; ?>">
		<?php if( !empty($url) ){ ?></a><?php } ?>
	</div>
</div>
<?php endforeach; endif; ?>

Thanks for your response. I added this code to my template and changed:

$images = acf_photo_gallery(‘image_gallery’, $post->ID);

to

$images = acf_photo_gallery(‘my_acf_gallery_slug’, $post->ID);

But it is not showing anything. Is there something else that I need to change?

Thanks

Hi @phoenixobia
You can do var_dump( $images ); to see if anything is being received by the function. Also make sure the images are uploaded. Check your error logs to see if any conflict errors.

Let me know

Hi. I added <?php var_dump( $images ); ?> in my template and made sure I have images added to the field. On the front end it displays:

NULL

Let me know if that helps. I can also give you access to my testing site if you need.

Thanks

I added the var dump as follows:

$images = acf_photo_gallery(‘photo_gallery’, $post->ID);
var_dump( $images );

It displays:
array(0) { }

I made sure I have added the photos and set their captions too.

Hi @phoenixobia
There is something else that you can try. Locate this function in your code acf_photo_gallery('gallery_images', $post->ID);. Hard Code the $post->ID something like acf_photo_gallery('gallery_images', 11);//11 is my $post->ID.

Which theme and plugins are you using, maybe if I can replicate this issue on my test site.
