acadia Posted July 28, 2009 Share Posted July 28, 2009 Hi All, I have a form which submits information to a database. The dropdown on the form auto populates two fields which can both be changed at input 1)Assessment Hours 2) Training Hours The next field i need is Total Hours. What I would like it to do is add 1+2 together to output a number. I am guessing this is going to involve some javascript but is there a function in PHP to do this?

vineld Posted July 28, 2009 Share Posted July 28, 2009 If you wish to do so without reloading the page you will need javascript. Then this is not a PHP issue. Simply add an event to each of the two fields and then update the third field.
