New views handler for multiple value fields - show count

This wouldn't have (as) been easily possible in Views 1, but is very doable in Views 2.

hello all, i'm interested in doing this too in Views 2. could anybody please share how?
thanks in advance

this would be great. the nodereferer.module already do the exact with back references.
for example you could have a column in your table that shows how many nodes of type B have refered to this node.
and i think it should be discussed on views issues not cck.

I have just been looking for this. I believe the Field API would need to expose the item count of multi value fields to Views in order to do this.

Found several posts looking to do this in general

Also requested here deletion, sorting and paging for multi value fields:
#1267476: Multi Value Fields - paging, sorting, deletion

Views handlers for fields are provided by the Views module in D7/D8.

In general it would help here a lot of the new handler could be inherited from the views_handler_field_field.inc but at the moment you will always render multiple values because render_item is defined. Perhaps $items could be changed right so this doesn't matter.

You can't undefine a method of a class in a subclass in php.

You can kind of accomplish this (at least in the way I needed it) using Aggregation and Count DISTINCT. This lays it out actually - http://drupal.stackexchange.com/a/44185/6581

It would be nice to have a count of multiple values available. There are times when I would use aggregation to sum the counts of values.

In Drupal 8 the Views module was moved into core, so I'm moving this issue into the core issue queue.

Going through old issues.

Not sure if adding a field handler for this would be the way to go here, expanding the 'Multiple field settings' in \Drupal\views\Plugin\views\field\EntityField::multiple_options_form with a 'count' option might work, or people could do this in a theme since you can just run this through '#theme' => 'item_list'

But offering this option might help people avoid switching on aggregation which always brings a whole new set of problems

It would be great to have this :)

This would be great. In addition to count, it could sum, average, etc.

In the meantime, field_count_formatter module is useful.
