Add a formatter for file entities?

Pretty sure you can use views to achieve this.

I mean, why not just use a view to create a flexslider block/panelpane or even use a views-field to print it where you want? I just had to do this exact same thing today, that's why I came across your post. Just seems unnecessary to create a module for it... I ended up using a view in a panel pane and it works like a charm, I am using a media field with files, images, youtube and vimeo video's, all displayed in a uniform way through views.

I agree it would be a lot more easy if the module provided this functionality :)

I think that we have "simply" to add some code to the module, that now works only for "media" and "image" fields.
Adding "file" is not enough..

I won't be adding this to the module myself. But if someone wants to write the patch I'll be glad to review.

Changed to htmlentities

Here we go.
The attached patch adds a formatter that integrates with file entity view modes.
That way the rendering of the single file item is handled by the file entity module with the file display settings and flexslider fields just takes care of, well, sliding.
This should work with image, media and file fields.

This approach also provides a away to render responsive images with the picture module.

Patch looks good, only found 2 minor code style issues.

@attiks Thanks for the review :)
Both comments are adjusted.

Btw. a bit off-topic but is there a reason why we've to render the things to put into $item['slide']?
I think the code would be more "flexible" and thus easier extensible when we would do a render($vars['item']) in theme_flexslider_list_item().

Works for me. RTBC?

Nope. Kept getting the following notice:

Notice: Undefined variable: is in flexslider_fields_field_formatter_settings_summary() (line 134 of /sites/all/modules/flexslider/flexslider_fields/flexslider_fields.module).

The attached patch fixes the issue.

The patch from #12 works. Thank you all very much, it was exactly what I needed.

Would this formatter allow for a mix/choice of

- responsive images (picture)
- video embed

at the same time?

@groovedork

Yes, both responsive images and video embeds are possible with the file entities formatter. The one thing I haven’t been able to do is to make video stills responsive.

I've never applies a patch before, so I might be doing it wrong, but I get an error.

// nevermind, the patch should be run against the dev version. Could have known that..

#12 is working well for me, too. Let's get it committed, please.

Re-rolled #12 against the latest dev.

Instead of calling the hook_field_formatter_view in File Entity directly

    $file_items = file_entity_field_formatter_view($entity_type, $entity, $field, $instance, $langcode, $items, $file_display);

It should be using module_invoke instead. That way other modules can alter (I know right now field_formatter_view doesn't have an alter hook but there's a contrib module that adds one or something apparently). Either way, shouldn't call hook invocations directly.

Also, could you include some docs in the README.md file explaining how to use this and in what cases it makese sense to use it.

Once that's done, I'll give it another look and I think we'll be good to go.

@minorOffense Thanks for the feedback.
Here we go, hope the readme addition makes sense.

This appears to be working fine for me. Thanks, das-peter.

Thanks everyone.
