I really think you should read through the examples given under the ajax()
documentation, and the tutorials available on Ajax (and possibly some of the
others too) - look for Tutorials on the jQuery website Documentation page.
The ajax() examples show you what needs to go in your calling program
(presumably test.php), and I've already explained one way to get php to
return data (HTML or JSON).
The 'block' is simply the JSON structure that the success handler would see
in my particular example.
Is it complete? You can see it is by comparing it to what my example php
code echoed. For what you might want to do, who knows.
