Problem with adding custom CSS class to image in ACF Photo Gallery plugin [closed]

Question

I am using the ACF Photo Gallery plugin (ACF addon that adds an image gallery option). I'm trying to add the option of giving my own CSS class to a particular image, all by the tutorial ->https://wordpress.org/plugins/navz-photo-gallery/ (Usage, Add Extra Field), but unfortunately for some reason the CSS class does not appear In the code. I paste below my comment code (there is not much). Where did I make a mistake?

/// I put this to functions.php, in edition in particular image window appears with css class field <?php function my_extra_gallery_fields( $args, $attachment_id, $field ){ $args['class'] = array('type' => 'text', 'label' => 'Kolor produktu', 'name' => 'class', 'value' => get_field($field . '_class', $attachment_id) ); /// I think the problem may be here return $args; } add_filter( 'acf_photo_gallery_image_fields', 'my_extra_gallery_fields', 10, 3 ); ?> /// I put this code to single-portfolio.php <?php $images = acf_photo_gallery('gallery_images', $post->ID); /// gallery_images to slug pola galeria w ACF if( count($images) ): foreach($images as $image): $full_image_url= $image['full_image_url']; $class = get_field('gallery_images_class', $id); endforeach; endif; ?> /// This code displays image, CSS class should appers, but it doesn't <?php foreach($images as $image) { ?> <img src="<?php echo $image['full_image_url']; ?>" class="<?php echo $class; ?>" > <?php } ?>

Try this code at the place where you want your gallery:

<?php $images = acf_photo_gallery('gallery_images', $post->ID); /// gallery_images to slug pola galeria w ACF if( count($images) ): foreach($images as $image): $full_image_url= $image['full_image_url']; $class = get_field('gallery_images_class', $id); echo '<img src="'.$image['full_image_url'].'" class="'.$class.'" >'; endforeach; endif; ?> 

Do try to check if '$id' gives you the image/post id (not sure what is needed here).

EDIT: Please check if $id and $class are correct. you can do this by using this code:

<?php $images = acf_photo_gallery('gallery_images', $post->ID); /// gallery_images to slug pola galeria w ACF if( count($images) ): foreach($images as $image): $full_image_url= $image['full_image_url']; $class = get_field('gallery_images_class', $image['id']); echo '<img src="'.$image['full_image_url'].'" class="'.$class.'" >'; endforeach; endif; ?> 

It could be possible that `$image' in your foreach has an ID. Try to use that one instead.
