This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to create a slider. Each slide should be an image from a repeating custom field in a single post, along with its caption as stored in the Media Library.
Solution:
This isn't possible using a standard Views slider. This approach requires custom code. Follow the steps outlined in this post:
https://toolset.com/forums/topic/create-a-slider-with-multiple-images-from-image-fields/
To display the image caption, add this custom shortcode function to functions.php:
add_shortcode( 'toolset_get_image_caption', 'toolset_get_image_caption_func');
function toolset_get_image_caption_func($atts)
{
global $wpdb;
$url = $atts['url'];
$id = $wpdb->get_var( $wpdb->prepare ("SELECT ID FROM $wpdb->posts WHERE guid=%s ORDER BY `ID` DESC", $url ) );
$excerpt = get_the_excerpt($id);
if($excerpt)
return $excerpt;
$attachment_meta = get_post_meta( $id, '_wp_attachment_metadata', true );
if (isset($attachment_meta['image_meta']))
return $attachment_meta['image_meta']['caption'];
}
Then use the shortcode like so:
[toolset_get_image_caption url="[types field='gallery' url='true']"]
