Cookie Errors

[pinehead18]

Ok this is a great question for you.....

function welcome() {
        if ($_HTTP_COOKIE_VARS['user']) {
        $sql = "SELECT fname FROM users WHERE user='$name'";
        $result = mysql_query($sql) or die(mysql_error());
        $row = mysql_fetch_array($result) or die(mysql_error());
        $fname = $row['fname'];
        } else {
        $fname = "Guest - <a href=loginbox.php>Login";
}
        echo "Welcome, $fname";
}

this is my code.. However it does not work correctly.. it always displays $fname= "Gest" login .. and not the other part.... HOwever i know that the cookie named user is present.

When i change if(!$HTTP_COOKIE_var['user'] the screen goes white.. and will not post anything.. or if i use $_COOKIE it does the same thing. And the code up top doens't even read the cookie.

Any suggestions?

Thank you
Anthony

The variable $name that you are using in your query is not available to that function. You must use the global statement inside your function to bring it into the scope.

function welcome()
{
global $name;
//code here....
}

see http://php.net/variables.scope for more information on accessing global variables in your functions.

Actually, since you mentioed that i defined what name was on the same page. Then echoed the name on the same page.. YEt the function still does not work...

Any other suggestions?
