Required On Publish

Synopsis:
It will let you save any node in unpublished state even if there are some required fields left unfilled.

Generally no user is allowed to save any node in either published/unpublished state if you have some fields left unfilled which are required.

But what if you want your user to save partially filled node creation form even if they have left some required fields empty?

Their comes "Required On Publish" module, which provides another option in parallel to required in field settings form for each field of every content type. Now check mark the required on publish check-box wherever you want your field to be required.

This gives user the liberty to save node in unpublished state irrespective of any required field.

Now, when the user publish the node then required fields act accordingly and generate error if any required field is left empty.
