Integrate with Inline Entity Form

Field Collection would need to add IEF integration to their module.
Let's see what the Field Collection maintainers think.

Is there any update on this issue at all?
Anything in the pipeline maybe?

It seems like it should be possible, though I don't believe anybody is currently working on it. Patches are welcome. Please stop posting in this issue to ask for updates or to 'bump' it. When there is an update it will be posted.

I am wondering why do you even need inline entity form for field collection when something very similar is already there in FC module as default, what is the difference, they behave almost the same.

@Marko

Good Question.. But when we need multiple forms ( Add another) then inline forms are good. Other way of using for this scenario is to use Node Connect or Entity reference module to open the form using Reference Dialog module. This is somewhat not a nice approach in UI Perspective. Inline Entity provides a nice UI for better user experience.

I don't understand the motivation behind this either. Why are inline entity forms better than the embedded field collection widget when we need multiple forms (Add another) ?

If the data is huge (like many fields) we can chunk it using inline form as it is saved independently and final save is done at the main node and hence a vast improvement on performance related to time it takes to save.

Yes, that does make sense.

A use case I would implement would be to use field_collection, entity_reference and inline_entity_form modules together to create a simple workflow for content editors so they will be able to choose from a list of field collections.

This would be similar to what the paragraphs module is doing.

@ jmuzz,Marko B; your comments seem to imply that the use case I mentioned is possible with field_collections. Is it possible? What did I miss?

@mengi I don't think your use case is possible, I was just trying to understand the purpose of using inline entity forms instead of the inline forms that field collections provide. The problem is a field collection isn't just an entity, it is also an entry in a field in its host node. The machine name of that field is the bundle of the field collection, so you can't put field collections of different bundles into one field in their host.

An alternative way to achieve this would be to use ECK instead of field collection. Create a simple entity with 1 or more bundles and add the fields.

This entity can then be referenced by inline entity form as many times as you like, even within the same content type.

I need same integration and I get the same error. I builded a patch that fix the problem, at least for basic functionality. But IEF have problems with validation when using it inside field collection field, so I builded another patch for that module (2853216)

I added to the patch IEF compatibility when field collection item is deleted.

I repair the last patch because I get errors when deleting field collection item.

I added some variables to context so other modules can be aware of empty evaluation.

It is more usefull if the alter ief empty condition is done every time

Add validation to prevent php warnings
