Drupal 8.x

I am creating a custom field widget where a user can click a button and edit some fields in a form inside a dialog modal.

Opening the modal works fine, but I cannot seem to make any buttons inside the modal form react to anything I throw at it.

In the below example, when clicking the "submit" inside the modal form, the "submitAjax" function is not executed, and I receive a standard AjaxResponse in my network debugger. I've tried using different class names "use-ajax" and "use-ajax-submit", I also tied without any.

I have a view filter criteria that includes a zip code and miles field. Zip is text box while miles is a radio button with options 5,10,15,20.

When zip and miles are entered the below query should be called:

@from_zip should come from zip field @miles should come from miles field

I am using View data export module to perform data export in Excel. I am getting

Error: Class 'Drupal\xls_serialization\Encoder\Spreadsheet' not found in Drupal\xls_serialization\Encoder\Xls->encode() (line 70 of modules\xls_serialization\src\Encoder\Xls.php).

I am aware that the below query can fix this issue:

I have an "entity_reference" field which displays an "entity_autocomplete" form field.

I would like the user to select only one value.

The problem is that the field allows the user to enter multiple values (separated by commas), even though I set the field cardinality to 1 and "Tags" is false by default.

Greetings Smart Jedi Drupal Masters:

I am creating a campground directory. I have a question. I want campground owners to upload updated images to a particular node (Campground) instead of dumping them in a big folder with everything else.

I am trying to keep all the images tucked in a simple folder concept -- easier for me to ensure keep tabs on everything.

The structure I have for campground images is public:/listing-gallery/state/campgroundname/images
