获取数据到数据库并重新插入（如果匹配）

I'm making a php search form that the user will type their id and if has match it will re-insert the data to database.

I manage get the data and display the value under my submit button.

My problem now is how to insert data after search. Is it possible to re-insert the data in same table if has a match?

Here is my code:
