Ce fil est résolu. Voici une description du problème et la solution proposée.
Problem:
The user would like to use a background image from a custom field and fallback to a different image when no images are available.
Solution:
This can be done using a conditional block and checking if the image exists. If it does, then use a container that has the background set that image field. Otherwise, use another container that has the background image set to a specific image in the Media library.

Set an dynamic background-image in toolset container with Gutenberg. Background image is a toolset custom type "image".
In single template i want to check if the background-image exist and if not, show an autogenerated image.
So i tried to catch the type field rendering with the filter "wpv-post-field-meta-{name}", to check if meta-value is a valid, existing image.
I expect that filter should be fired if i use the shortcode [types field='meetup-pre-image'][/types] for rendering this field.
Unfortunatelly the filter doesn´t fire. Question is why or how could i reach my goal to render an alternative image if background-image not exist?
function cb_prefix_empty_meetup_pre_image( $meta ) {
if ( empty( $meta ) ) {
die();
$meta = array( __('No value') );
}
return $meta;
}
add_filter( 'wpv-post-field-meta-meetup-pre-image', 'cb_prefix_empty_meetup_pre_image' );
add_filter( 'wpv-post-field-meta-wpcf-meetup-pre-image', 'cb_prefix_empty_meetup_pre_image' );
