    onClick

    Does php work with onClick in an html input statement?

    <HTML>
    <input type="button" name="add_pictu re" value="Add another picture"
    onClick="<?php picture_count() ; ?>">

    I want to call the function picture_count() when button labeled "Add another
    picture" is clicked in HTML

    I do not want to use submit in place of button since I do not want to submit
    the form at this time.

    With the above statement, I receive an error expected ";" and the function
    is not called.

    Thanks!

      The function will not be called because:

      A) PHP is serverside whereas the onclick event you are trying to catch
      is client side.

      B) the onclick attribute is (to my knowledge) expected to refer to a
      javascript function/statement.

      From what you've posted I can't tell exactly what is supposed to be
      done when the user clicks the button (ie. what your function does) but
      maybe you can consider using some javascript to reload the page and
      update whatever your function was updating.

          You are mixing two different technologies together... PHP is server side
          - The onClick event is client side... This means that your PHP code is
          parsed/run BEFORE it gets to the user/client side.

          If PHP is correctly configured on your server, then view the page where
          you have the above code - My bet is that in the 'onClick' event, you
          will NOT see <?php picture_count() ; ?> but instead see the result of
          picture_count() - And unless you manage to store the value/result of
          picture_count somewhere on your server, then I'd guess that the value
          will always be the same, no matter how many uploads you did.

          Chances are, someone in comp.lang.javas cript will (at least in part)
          help you towards a solution...
