Dynamic Content Gallery

Hi,

since it's not possible to create a dynamic content gallery within divi itself (why? ;-)) I try to build it on my own but it drives me crazy.
I'm using Toolset and created a custom post field with the field-type: image.
I allowed multiple instances of the field. So for example if I'm uploading 3 images, there are 3 instances of this field.
The value of the field is the URL of the image.

In the internet I only found solutions in conjunction with ACF-Plugin. But this is not a solution for me.
I can't get over it with. Maybe someone have a solution. My code looks like that:
(CSS-ID of Gallery-Module is "gallerie2")
(My custom post field where imag-url's are stored is: "wpcf-post-bilder")

function custom_toolset_gallery_ids($attrs) {
// Überprüfe, ob das Divi Gallery-Modul verwendet wird
if (isset($attrs['module_class']) && strpos($attrs['module_class'], 'gallerie2') !== false) {
// Hole die Bild-URLs aus dem Toolset Custom Post Field
$image_urls = get_post_meta(get_the_ID(), 'wpcf-post-bilder', false);

// Wenn Bild-URLs vorhanden sind, setze sie in das Attribut
if ($image_urls) {
// Verwandle die URLs in eine durch Kommas getrennte Liste
$attrs['gallery_ids'] = implode(',', array_map('esc_url', $image_urls));
}
}
return $attrs;
}
add_filter('et_pb_module_shortcode_attributes', 'custom_toolset_gallery_ids');

 

Thank you very much for the hint. SOLUTION FOUND!
For everybody else who have this problem here is the code which is working for me:

function custom_toolset_gallery_ids($attrs) {
// Überprüfe, ob das Divi Gallery-Modul die CSS-Klasse "gallerie2" hat
if (isset($attrs['module_class']) && strpos($attrs['module_class'], 'gallerie2') !== false) {
// Hole die Bild-URLs aus dem Toolset Custom Post Field
$image_urls = get_post_meta(get_the_ID(), 'wpcf-post-bilder', false);

// Wenn Bild-URLs vorhanden sind, setze sie in das Attribut
if ($image_urls) {
// Verwandle die URLs in eine Liste von Attachment-IDs
$attachment_ids = array_map('attachment_url_to_postid', $image_urls);

// Wenn die Konvertierung erfolgreich war, erstelle eine durch Kommas getrennte Liste der IDs
if ($attachment_ids) {
$attrs['gallery_ids'] = implode(',', $attachment_ids);
}
}
}
return $attrs;
}
add_filter('et_pb_module_shortcode_attributes', 'custom_toolset_gallery_ids');

gallerie2 is my CSS-Klass of Gallery-Module
wpcf-post-bilder is my custom post field made with toolset.
