Hi there, I am looking forward to discussions on this forum. To start
with I wanted to ask if it was possible to do clients side and server
side form validation in the same form. I think it should be ok, but it
may be a bit complex. The reason it my forms are so big that I want the
user experience to be a best as possible.

I would do this with the ajax plugin. Say I wanted to have one field
(username) be checked with AJAX (against a MySQL database) when the
field loses focus and the rest are validated with JavaScript upon submit
button press.

It this a good way to do this, do any of you have any examples of such a
php page?

best regards
