  1. Day 17 Programming for Designers

  2. Javascript and PHP • Client side and Server side • Since PHP is Server side and can output anything we want, we can output to JS. • With JS libraries, we can create flash like effects that go beyond the client side. • Common uses: • Transition Effects/feedback • In-place editing, form controls • Many more…

  3. JS Libraries • jQuery • Prototype • MooTools • Yahoo YUI • EXT JS • DoJo Toolkit • MochiKit • Many many more..

  4. jQuery • Write Less, Do More • “jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages.” • Easy to use, extensive documentation, plugin ability, well supported, small download.

  5. What about PHP again? • PHP and JS work together in two ways. • PHP output to JS • JS output to PHP through AJAX • Once a page is sent to the client, JS can work, but can’t directly communicate with PHP on the server without AJAX. • jQuery makes this process simple.

  6. Method • PHP output to JS on server side. <?php echo ‘<script> alert(“This is javascript.”); </script>’; ?> • You can output JS the same way you output HTML, PHP makes no distinction.

  7. Cool PHP and JS Uses • Automatic Random Picture Rotator • Self Submitting Forms • Auto-save capabilities • Unique Username and Email checker for new user account creation • Change CSS formatting on the fly • Edit in-place form data • Instant rating system
