Re: [PHP] Saving css state in javascript and passing to php via form submit

I think you want to use sessions for this :)
Ok, i can put the data in the session variable, but i can
only get the
"current" state through javascript

ie:onsubmit="getstate()"; which would get the id's of the
blocks that
are set to display:block;

But in getstate() how do i pass that to php to set that
session variable?

You could use AJAX to get things from/to PHP, but why should you?
You can use session within javascript too i believe.
Hmm javascript setting server-side session data??
Sounds weird, but i'll look into it..
server-side session data? i never heard of server-side sessions...
AFAIK they are send in the HTTP headers from and to the server.
Cookies are nearly the same as sessions, i found this article (with
examples) that goes about parsing cookies from javascript. So
you could also do it with cookies.

Ermmm...
Isn't $_SESSION a superglobal available only during script execution?
Yes it sets a session_id in a cookie to which is sent to the server to
identifie the client, but to my knowledge $_SESSION['my_var'] = 'some_data';
is stored server side and set only through a server side script...

Now storing data in cookies is client-side, that i agree..
Am i confused or are you confusing me? :P

ps. Maybe you could also use AJAX instead of submitting forms
the whole time.
In the next version of my framework i would like to, i still
havent quite understood the whole concept, not enough research
yet, but yes
i'll be doing that next ;) (you know deadlines, can't sit
and read docs all day etc..
Although i'd rather!)

Really, it's not that hard to use AJAX. You might want to look at
www.tizag.com, there it is really easy explained.
It's nothing more then making new request to scripts inside
javascript.
Nice tutorial thanks for that, i'll look it up, maybe
intergrate it
right away, would really make my day if i could :))

It's not too hard, but if you already did a lot of work on
the form processing, you prefer not to write it all over
again i think ;)

Wrote a class to do the form validation, so i could always make a .php that
runs the form data through the validator and sends back the response.. In
xml i think it has to be?

the response doesn't have to be in any particular form ... ofcourse the X in AJAX
refers to XML but it's not obligatory .... in the end your just spitting out
a big long string and your clientside code can do with it whatever it wants.

personally I prefer JSON formatted data, for which there are even a couple of
functions available in newer versions of php (otherwise you can find code on the net
easily enough to handle JSON data creation/parsing):
