Modify create content flow I want to do the following:


filling content (create new content)
after pressing the save button (submit) will display the contents of the data has been filled,and other additional information required
select save to submit the content, or cancel it


How do I show data that has been filled as a confirmation before the data saved?

I have tried using the Form API to change the flow of the process (_form_alter) but no success. And i can't find the examples to altering the content type.
Provide the roles to user to make any content and after save the content it will show with restriction.
Or 
you can make custom module for that.
