Question:

We are only able to add one row in the database, using forms in HTML. How can we do multirow operations on the HTML before sending it to the server?

Answer:

Present your database records in a grid format of text boxes. The user can fill the data into the text boxes and when the Submit button is pressed, all the data will go back to the server.

On the server side, you will have to write code to access all the rows of data and update your database. You need a unique primary key (say ID) to identify each row.
