Quoting Alain Roger <raf.news@xxxxxxxxx>:
you understood right.
basically my problem is that the layout avoid it.
here is "something like" my layout :
<div#0>
<div#1>Lanague (label) : <img flag> <img arrow to show all languages from
div#2></div#1>
<div#2> all flags</div#2>
<div#3> login field + pwd field + submit button</div#3>
</div#0>
till now i only use AJAX to refresh the content of div#3
but it does not change the label from div#1 when user selects another
language from div#2.
Well it looks like you need a extra Ajax call to the server.
Click a language flag sends a request to the server. The server
responds with an JSON object. Containing the content for <div#2>. With
javascript you can update the contents of <div#2>
if i place the whole form into a PHP i face several questions :
- how the ajax will reload this PHP page (reloading itself) in the parent
control div#0 ?
If you would like to reload the whole of <div#0> You could send and
JSON object from PHP to javascript. And let javascript generate the
div structure and update the DOM.
- when user will click on submit button, where will be loaded the content
return of checking if log+pwd are correct ?
When a user logs in a Ajax request is send to the server. the server
responds with an JSON object containing the error message. With
javascript you could update the contents of <div#3> to display a
message.
- how to redirect to another PHP page, when user click on submit button ?
the redirection will happen only in the content div, so only in div#0 and
not into the browser :-(
I have a hard time understanding this last issue. What exactly do you
mean by redirecting to another PHP page?

Making an Ajax request for one little label maybe a bit overkill.
As i understand you request the whole form through an Ajax request. And
display this to the user? And every language generates a new form?
Why not just create the form dynamically with javascript and load the data
from PHP. So the form can stay the same for all calls. You just fill it with
data depending on the language selected. You can fill the form for instance
by sending a JSON encoded object from PHP to javascript.
