    Compute and display data on the same page

    well,
    when user inputs the data, i should be able to fetch the data from the database and do some numerical computaions and display the result on the same page before i submit the data to the php script,

    the php script takes all the posted data and dump it into the database,


    how to achieve this

    me using
    PHP 5.0/MySQL 4.0

      What code do you have so far?

      This should be posted in the PHP forum, but don't double post. A moderator will probably move it soon.

              Look into the use of Javascript to process data on the client side, or if you really want to get creative, AJAX.

                  Looks indeed like the perfect problem to tackle with an Ajax solution. That way you can, after the user has inputted some field(s), go to the server database, get the data and display it on the screen. All without screen refreshes.

                  But, as acoder put to you in an earlier post: "What code do you have so far?". Show it and we will see where we can assist you.

                      {
                      f = document.form1;
                      superficial = parseFloat(f.a. value) + parseFloat(f.b. value)
