how to let the user to choose his languages?

Not sure why the language selector is not showing up. You can always change the language to a desired language by adding -lang=xx where xx is the language code of the language to change to.
So you could just add a link to
to change to english
to change to french

how to change the light to left alignement for each languages?

This can be done with CSS:

So what you need to do is add a block with css that depends on the user's chosen language.
You can always obtain the user's current language by:
Code: Select all
$app =& Dataface_Application::getInstance();
$app->_conf['lang'];  // something like 'en' or 'fr'

So you could modify the custom_stylesheets block in the ApplicationDelegate class to handle this case:

Code: Select all
function block__custom_stylesheets(){
    echo '';
    $app =& Dataface_Application::getInstance();
    switch ( $app->_conf['lang'] ){
        case 'ar': 
            echo '';


i want to count the user online

For this you'll probably want to create a table that keeps track of the users who have accessed the script in the past X number of minutes (e.g. 5 minutes). You'll want to store:
1. username (unique)
2. IP address (unique)
3. timestamp

An appropriate place to add code for this would be in the getPreferences() method in the application delegate class because it is executed on every request after the user authentication has been handled.

you might do something like:
Code: Select all
$user =& getUser();
mysql_query("delete from online_users where `username` = '".addslashes(getUsername())."' or `ip_address` = '".addslashes($_SERVER['REMOTE_ADDR'])."' or `timestamp` < '".(time() - 300)."'", df_db());

mysql_query("insert into online_users (ip_address,username,`timestamp`) values ('".addslashes($_SERVER['REMOTE_ADDR'])."','".addslashes(getUsername())."','".time()."'", df_db());

Then you could always access the number of users online with:
Code: Select all
$res = mysql_query("select count(*) from online_users", df_db());
list($num) = mysql_fetch_row($res);
echo $num; // The number of users currently online

more or less..
