php - how to insert in a table like shown in this image where tusername is come from previous page -

I have a page where I send it to Tuenza and found on page 2 where a form is formed. I want to add more than one data to the table using that form. Where the id is requested and the sub-code is entered by the table, it will save the data like this.

  & lt ;? Includes php ("db.php"); $ Tusername = $ _ Request ['tusername']; Update in values ​​('$ sub_code', '$ tusername'), in 'TechSub' (subcoda, tusname), where tusername = '$ tusername');? & Gt; & lt; html & gt; LT; body & gt; form method = "post" & gt; subject one: input type = "text" name = "subcode" & gt; & lt; br & gt; subject two: & lt; ; Input Type = "Text" name = "subcode"> <3> topic three:  
 
 subject Four: input type = "text" name = "subcode"> 
 input type = "submit" value = "ass In ">     

I think it can help you
