User in every form

I am planning adding Issued By: (user who login).
Example:

Reference
1001
Issued By:
Wahyu
Date
9/27/2018

I know where to put it. it should be around

                    <div style="font-weight: bold">Reference</div>
                    <div style="margin-bottom: 10px">1001</div>
					
			____IN HERE_________________________________		
                    <div style="font-weight: bold">Issued By:</div>
                    <div style="margin-bottom: 10px">**Wahyu**</div>
                    
		______________________________________			
					<div style="font-weight: bold">Date</div>
                    <div style="margin-bottom: 10px">9/27/2018</div>
                    
                </td>

User who make this is wahyu
Is there a way to make wahyu generated automatically basically by login session or the maker without manually adding.
