Possible to prepopulate an inline entity form multiple with a url parameter?

Question

Is is possible to add multiple entries into an inline entity form field with url parameters

I am able to populate almost any other field with the prepopulate module, just having difficulty with the IEF.

Scenario:

I have two content types of quote, and sales order. each of which has an entity reference of inventory (another content type) which has IEF as its widget.

I want to be able to create a sales order off of the quote, and bring over all the values of the entity reference field to the quote. The issue is i want to maintain the data on the quote, but be able to edit the "same" data on the sales order.

Please try with Entity reference autofill and Entityreference prepopulate Modules.

1. Add an entity reference field in your entityform.
2. The entity reference autofill will automatically fill reference value into field. We can load default value from URL. (?field_name = value)
3. Entityreference prepopulate will prepopulate the values. (you have to add existing fields for that.)

For more details please refer project page.

Another approach is,

If you want to do this by coding, Just pass nid through url and use node_load() to load that node and create an entity form submission. If you want to create entity form with node creation use hook_node_insert or hook_node_presave.

Hope this will help you.
