    Keyboard navigation in photoalbum

    Hi!

    I've just started to learn PHP, so this may be a dumb quiestion, but I'll
    ask it anyway...

    Is it possible to create a photoalbum (or make use of such) with PHP,
    where I could navigete with my keyboard? When some picture from a gallery
    would be selected, could I navigate to next or previous picture by using
    for example buttons "n" and "p" from my keyboard? Is this possible to do
    with PHP or should I use JavaScript or such instead?

    Thanks!

      php is server side. Your script has finished execution by the time the
      document is displayed.

      Javascript can capture keys:

      function keypress() {
      key = event.keyCode;
      }

      document.onkeyd own = keypress();

          If you want to use an existing album site, try Opera 7. It can
          automatically work out which links are the "previous" and "next" ones.
          You can navigate these links by pressing CTRL+ the left and right
          arrow keys. I find this feature invaluable for speedy browsing of
          search results from Google, eBay, etc.

          If you're writing one and want to add this feature, try adding LINK
          elements in your <head> thus:
          <link rel="prev" href="album.php ?page=4">
          <link rel="next" href="album.php ?page=6">

          Some browsers may allow keyboard navigation of these links.

          I was also going to suggest using the accesskey attribute, but from
          what I've read it appears poorly supported and inconsistently
          implemented.
