Hi Chris,
Can I try to clear something up here, Javascript and PHP validation are
two mutually exclusive activities, the only ways they relate to each
other are:
1. PHP can output the validation JavaScript to make it semi-dynamic (eg
check for a specific value based on a database field etc.)
2. JavaScript validation can stop a response being sent back to the
server (so PHP validation will not occur.)
3. JavaScript can also be used to initiate and listen for AJAX
communications to a PHP page. (May be used for validation, but is often
used for dynamic sorting or additional information display)
My advice with the JavaScript side of things is make it work by hand in
Firefox (about 90% of the time if it works here it will work in Opera,
IE and Safari). Then include the working JavaScript in the PHP you are
using to generate your page . If the JavaScript now stops working, view
the client-side page source, not the server-side, to see what's wrong.
Often having a look at the JavaScript Console in FireFox will give you
a few pointers with JavaScript faults. Once you figure out what is
wrong with the generated html, update the server-side source to stop
the problem from being regenerated.
Hope this helps
William
