$HTTP_USER_AGENT not available from within header.html?

$HTTP_USER_AGENT not available from within header.html?

placing

print "$HTTP_USER_AGENT";

in the body of the /theme/standard/header.html file does not return anything. I need to do a browser picker using

if (strstr($HTTP_USER_AGENT,"MSIE")) {
    print "Your browser is Internet Explorer";
}elseif (strstr($HTTP_USER_AGENT,"Mozilla")) {
    print "Your browser is  Netscape";
}

Where in the moodle code is the return of $HTTP_USER_AGENT stopped from being called from header.html OR does anyone have a solution to this problem?

You should access it using this syntax:

$_SERVER['HTTP_USER_AGENT']

...this will work in any context. On a related note, I'm currently trying out this code in lib/setup.php to let Google into the moodle.org forums as a guest:

    if (empty($_SESSION['USER'])) {
        if (!empty($_SERVER['HTTP_USER_AGENT'])) {
            if (strpos($_SERVER['HTTP_USER_AGENT'], 'Googlebot') !== false ) {
                $USER->id = 153;
                $USER->firstname = "Guest";
                $USER->lastname = "User";
                $USER->username = "guest";
                $USER->email = "guest@moodle.org";
                $USER->loggedin = true;
                $USER->confirmed = 1;
                $USER->site = $CFG->wwwroot;
            }
        }
    }


I'll let you know how it goes and might make it an admin option.

Thank you Martin. It all works now!

See a friend is online in the moodle application, click their name , their user profile is displayed with extra button "Chat to me Now". On selecting the button the friend gets (on their next action in moodle) in IE a predetemined chat opens with both parties within it, or on Netscape a button appears in the header "Alan wants to chat with you Now. Click to chat." then the chat window opens. [Netscape will not open unrequested popups].

Solves client request but I would like something like a private chat to open, not a general social chat I have already set up.

Again thank you

Code attached.
