I'm very new to web developement. I wish to develop a purchase order application wherein it has fields po_no, item, item_description, quantity, price. Out of these items po_no is common to all entries. Initially the form will have one row containing item, item_description, quantity, price. I need an option of adding multiple rows by the click of a button and the generated form fields need to have dynamic name. On submitting the form, the same must be saved in the database.
I tried out the code from
but found no result.
Would be really grateful if anyone could help me out or suggest me where can i get the solution.
