Lightning component to Upload multiple files using public community before the record got saved. 
after the uploading the files we have submit button to save the record. and files need to attached to newly created record.

Hey everyone,
I have two components. one is a child where we collect the data for different types of fields. one is Parent where we have some buttons. when we enter the data in the child component upon clicking the save button on the Parent component it should create records in salesforce and also it should hold the saved values. Please refer to the below picture for a better understanding. Thanks in advance,

I have a visualforce page, which is published on communitis(public page),once they opened the page we are taking some inputs and creating the user with those details and redirecting to the login page and asking to login. once they login we need to open the same visualforce page and need to show other fields for entering the inputs.

"So here we need to apply some conditions to render some fields for guest user and some other fields for logged in user."

My Question is there any way to identify the the page viewer is guest user or logged in user..
