    you'll certainly need Ajax
    or to send the form and get-it back
    So, the user selected the date ($pdate) from the combobox,
    what is a "combobox" ?
    where it is ?
    I know this can be

      The combo box is in another part of the screen. The page is rather
      large. It is not a form. It just has one combo box, and once the
      user selects an item, I want the script to get the results from MySQL
      and display them, without having to redraw the entire page.......

      I know this can be done, I just do not know how.....

          As mentioned in a previous post you have only two options if you do
          not want a total page refresh...

          1). To bring over not only the options, but also the results of each
          option, and generate the entire page at once storing the results in a
          series of hidden div elements. Then when they select an option make
          that matching div visible. or...

          2). Query the server when an option is selected. If this is your
          choice then you must either use XMLHttpRequest and process the results
          in your callback handler or put your combo box in a form and set the
          target of the form to a (i)Frame.

          Unless you are dealing with a script that is being called from a
          different domain I would use XMLHttpRequest as any modern browser that
          can do one, can also do the other as they both require Javascript and
          all modern browsers support XMLHttpRequest in one form or another.

          If you choose method 2 (the (i)Frame method) your return code can
          include javascript that calls javascript methods in the parent frame.

          You're not going to be able to include PHP code inside your HTML and
          have it magically generate results for you on the client side.

          HTH.

              No, cannot include PHP on the client side, but how about calling a PHP
              routine on the server and returning the results? I've seen simple
              examples of this, though mine is a bit more complex......

                  That's where XMLHttpRequest comes in, that or the form submission
                  option. AFAIK there's no other way for a browser to initiate a server
                  request. So where are the simple examples you've seen, maybe that
                  would help enlighten me to your specific task.

                  Is it that you don't know/want to learn XMLHttpRequest or do you
                  really think there's an easier way? If you're uncomfortable with the
                  idea, you're pretty much stuck with encapsulating your select within a
                  form and plain ol' submitting the form, having PHP generate your
                  updated response page. But without a complete page refresh, you're
                  going to have to intiate an XMLHttpRequest, or generate a form
                  submission to an (i)Frame.
