a page with inner
function A(){
there is a checkbox
}
function B(){
unset(variable) or other code;
}
When page is loaded the check is off and is applied the code in B
I would like, for every click on check, to apply or not the code B,
and that check remain in the selction made;
selction achived not on server but in the pc because it is a form's check
used by other user, so not a global set

Agreed, but OP's native language is most likely not English and he is
trying his best to describe his problem in English. So, give him a
break since he is doing the best he can.
As I understand it, here is what he means -- and anver correct me if I
am wrong.
On his form he has a checkbox.
When the user checks this checkbox, he wants something done, namely to
run function B and do things.
When the user unchecks this checkbox, he doesn't want to do things.
So, the simplest way is to have a Javascript function which does the
following:
function newFunction() {
-- test on whether checked or not.
-- if not checked then return
-- if checked then do what he wants done in function B or call
function B
}
Now I am not sure what he wants as far as written to the PC, but I think
he may be able to accomplish what he wants via a cookie. As far as I
know, that is the only thing that can be written to the PC without a
user's explicit permission (and even that requires that cookies be
allowed by the user).
In any event, anver, you should take your question to
comp.lang.javascript as there is nothing in it having to do with php and
there you will find better help.

ok run a code B1 inner function B
> When the user unchecks this checkbox, he doesn't want to do things.
ok not more run code B1 inner function B (or run other code B2)

ok is necessary javascript;
steps are this
when page is loaded check is off (default) and run function B and its code
B;
if a user click on the check, is necessary to reload the page for run
function B and code B2;
> Now I am not sure what he wants as far as written to the PC,
simple:
if php or js achieved the value of check inner a db or server, oneother
user that use the same form will have the set of the first user; this isn't
correct;
thanks

The function above is a javascript function. No need to reload the
page, however you can do that if you want to. Otherwise, innerHTML does
the job.

I think you need to find someone who speaks your language and better
English and have them compose the post for you. I simply cannot
understand what you are trying to say or do. Sorry.
However, I will say this much:
php only gets the value one of three ways:
1 - the form is submitted and it gets the value of the checkbox (checked
or unchecked) from $_POST.
2 - a link on the page that passes values in the URL. You would have to
compose the value at the time of click. php gets it via $_GET.
3 - an AJAX call from javascript. It gets the values via $_GET from the
URL that the javascript sends.
In all cases php has NO connection to the user's PC because it ALL
happens on the server.
Why would you want to set anything (other than cookie) on the user's PC?
If someone else comes along is that person going to be using the same
PC? Normally you set things on the server in either a file or a
database table.
