Hi,

I only get this on an article page where I have a repeater to fill a “Flickity Slider”.

My Code is:

<div class="ar-karussell-wrapper">
<div class="ar-karussell">

	<?php foreach( $images as $image ): ?>
	<div class="carousel-cell">
	<figure class="article-feat-figure">
	<img data-flickity-lazyload-src="<?php echo $image['url']; ?>" alt="<?php echo $image['caption']; ?>">
	</figure>
<?php 
								if($image['caption']!="" ){
?>
<div class="img-caption-featured"><?php echo $image['caption']; ?></div>
			<?php }
				else{ ?>
			<?php } ?>
		</div>
	<?php endforeach; ?>
					
</div>
</div>

Does anybody see what’s wrong with it? It is working… but with “Show Error” I see these Warnings.

Thanks for Help in Advance
Greeting Mikkel

Sorry, can´t edit my original post. It is not a repeater – it is a Gallery Field…

What is $images? where is it set?

I’m assuming you have something like

$images = get_field('gallery_field');

please supply the code entire code for this field

Where is the gallery field, on a post? a term?

Hello John,

yes you are right – I forgot to put in another line of code:

<?php $images = get_field('bildergalerie'); if( $images ): ?>
    <div class="ar-karussell-wrapper">
    <div class="ar-karussell">

        <?php foreach( $images as $image ): ?>
            
            <div class="carousel-cell">
                <figure class="article-feat-figure">
                <img data-flickity-lazyload-src="<?php echo $image['url']; ?>" alt="<?php echo $image['caption']; ?>">
                </figure>

            <?php 
              if($image['caption']!="" ){
            ?>

            <div class="img-caption-featured"><?php echo $image['caption']; ?></div>
                <?php }
                    else{ ?>
                <?php } ?>
            </div>
        <?php endforeach; ?>
					
    </div>
    </div>
<?php endif; ?>

The Gallery is on a post.

Thanks for your reply!
Best Mikkel

I would start by seeing what is being returned by get_field

$images = get_field('bildergalerie');
var_dump($images);

Hi,

sorry for the late reply.

This is what I get with (for testing) 1 image:

I realized that this error message also appears in the Admin Area right above the Custom Fields.

Hi,

I can inform you, that the Error Messages are not caused from your Plugin.

I did overtake a website. I found in the functions a code, which provided an image gallery with “next / prev” Navigation. So every Image has its own URL.

define('ARBP_VERSION', '0.2');
define('ARBP_TYPE', 'ar_big_pictures');
define('ARBP_IMAGE_TYPE', 'ar_biggallery');

add_action('init', 'register_arbp_type');
//add_image_size(ARBP_IMAGE_TYPE, 930, 523, true); 

add_filter( 'intermediate_image_sizes', function($sizes){
    if (!isset($_REQUEST['post_id'])) { return; }
    
    $type = get_post_type($_REQUEST['post_id']);
    foreach($sizes as $key => $value){
        /*if(($type == ARBP_TYPE  &&  $value != ARBP_IMAGE_TYPE && $value != 'thumbnail')
           || ($type != ARBP_TYPE && $value == ARBP_IMAGE_TYPE)){*/
	if ($type != ARBP_TYPE && $value == ARBP_IMAGE_TYPE) {
            unset($sizes[$key]);
        }
    }
    return $sizes;
});

 
function register_arbp_type() {
	
	$labels = array(
		'name' => 'Diashow',
		'singular_name' => 'Diashow',
		'add_new' => 'Neu',
		'add_new_item' => 'Neue Diashow',
		'edit_item' => 'Bearbeite Diashow',
		'new_item' => 'Neue Diashow',
		'all_items' => 'Alle Diashows',
		'view_item' => 'Diashow betrachten',
		'search_items' => 'Suche nach Diashows',
		'not_found' =>  'Keine Diashows gefunden',
		'not_found_in_trash' => 'Keine Diashows im Papierkorb gefunde', 
		'parent_item_colon' => '',
		'menu_name' => 'Diashows'
	  );

	$args = array(
		'labels' => $labels,
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true, 
		'show_in_menu' => true, 
		'query_var' => true,
		'rewrite' => array( 'slug' => 'diashow' ),
		'capability_type' => 'post',
		'has_archive' => true, 
		'hierarchical' => false,
		'menu_position' => null,
		
		'taxonomies' => array('category'),
		
		'supports' => array( 'title', 'editor', 'author', 'comments', 'excerpt', 'thumbnail' )
	); 
	
	register_post_type(ARBP_TYPE , $args );
}

if (is_admin() && isset($_GET['post_type']) && $_GET['post_type'] == ARBP_TYPE) {
    add_action( 'wp_print_scripts', 'ar_big_picts_de_script', 110 );
}

function ar_big_picts_de_script() {
    wp_dequeue_script('wp-category-permalink.js');
    wp_deregister_script('wp-category-permalink.js');
}

When I delete this Code, the Error Messages disappear.

Just because I’m corious – do you see where the Problem is?

Thanks a lot for your Help!

Best
Mikkel
