functions

I have this function that looks for the user's group session variable and assigns a variable to the group session variable. Take a look at the third & fourth commented out lines. If i uncommented those lines it actually verifies that $group has a value and it is NOT EMPTY. Now going back to commenting out lines 3 & 4 when it runs thru the if(!empty($group)) {..... it actually comes out as being empty... :eek: .....what's wrong with my code? am i missing something? Please help. Thanks!

function getUserConfiguration() {

$group = $_SESSION["MM_UserGroup"];
//echo $group;
//die();

if(!empty($group)) {
    switch($group) {
    case "access1" : $configuration = "access1"; break;
    case "access2" : $configuration = "access2"; break;
    default: $configuration = "default";
    }
} else {
$configuration = "noaccess";
}

return $configuration;		
}

Well, I can confirm you're not crazy. 😉

I cut-and-paste your code and tried the following:

$_SESSION["MM_UserGroup"] = 'access1';
//$_SESSION["MM_UserGroup"] = 'access2';
//$_SESSION["MM_UserGroup"] = 'denyme';
echo getUserConfiguration();

As I uncommented each line everything worked fine. I got 'access1', 'access2', and 'default' on my test page.

It looks like something else going on in your code is changing things before your function is called.

Do you have the proper session_start syntax and so forth at the top of the page before any other output? (http://us3.php.net/function.session-start)

I would also try var_dump on the $_SESSION["MM_UserGroup"] variable just before you call your procedure to make sure the value is what you think it is and that it's being set.

Anyhow, my 2 cents, and I hope you get this resolved!

Thanks!

What is the actual value of $group when you echo it? Note that a value of 0 (zero) will cause empty() to return true (as well boolean false or an empty string value).
